Ansible Vault Usage + +### How Credentials Are Stored + +Sensitive data (Docker Hub credentials, image name, ports) are stored in `group_vars/all.yml`, encrypted with Ansible Vault. The file is safe to commit to Git because it is AES-256 encrypted. + +### Vault Password Management + +The vault password is never stored in the repository. It is entered interactively at runtime using `--ask-vault-pass`. In a CI/CD pipeline, it would be stored as a secret environment variable and passed via `--vault-password-file`. + +### Encrypted File Example + +``` +$ANSIBLE_VAULT;1.1;AES256 +33313938643165336263383332623738323039613932393034366566663834623931343937353161 +3434396331653966343466303138646234366464393065630a616662363939653539643733336638 +32333339366530373137353139313561343762313562666437303966363337633366623462326366 +... +``` + +This is what `group_vars/all.yml` looks like in the repository — unreadable without the vault password. + +### Why Ansible Vault Is Necessary + +Without Vault, credentials like Docker Hub tokens would be stored in plain text in the repository, exposing them to anyone with repository access. Vault allows secrets to be version-controlled safely alongside the code that uses them, without risk of credential leakage. + +--- + +## 5.

On subsequent runs it was not triggered because no changes were made to Docker packages — demonstrating that handlers only fire when their notifying task actually changes something. + +--- + +## 6. Key Decisions + +**Why use roles instead of plain playbooks?** +Roles enforce a standard structure that makes code reusable and maintainable. Each role can be developed, tested, and shared independently. A single monolithic playbook with all tasks mixed together would be harder to read, impossible to reuse, and difficult to test in isolation. + +**How do roles improve reusability?** +Each role encapsulates all logic for a single concern — the `docker` role can be dropped into any other project that needs Docker installed, without copying individual tasks. Default variables allow roles to be customized without modifying their internals. + +**What makes a task idempotent?** +A task is idempotent when it checks the current state before acting and only makes changes if the desired state is not already achieved. Ansible's built-in modules (apt, service, file, user) handle this automatically — unlike raw shell commands which always execute regardless of current state. + +**How do handlers improve efficiency?** +Handlers only run when notified by a task that actually made a change. Without handlers, you would restart Docker after every playbook run even if nothing changed. With handlers, Docker is only restarted when packages are actually installed or updated — avoiding unnecessary service disruptions. + +**Why is Ansible Vault necessary?** +Any secret stored in plain text in a Git repository is effectively public, even in private repos. Vault encrypts secrets at rest while keeping them version-controlled alongside the infrastructure code. This allows the full Ansible project (including secrets) to be committed to Git safely. + +--- + +## 7. Challenges + +- **WSL2 disk space:** The WSL2 Alpine distro had only 136MB disk space, not enough to install Ansible. Solved by installing Ansible directly on the Vagrant VM and running it against localhost. +- **Docker login module:** `community.general.docker_login` failed. Solved by using a `shell` task with `docker login --password-stdin` instead. +- **group_vars not loading with become:** Vault-encrypted `group_vars/all.yml` variables were not accessible when `become: yes` was set at the play level. Solved by passing variables explicitly with `-e @group_vars/all.yml` and setting `become: no` in the deploy playbook. +- **App port:** The application runs on port 8000 (FastAPI/Uvicorn), not 5000 as initially assumed. Discovered via `docker logs` and corrected in the vault variables and port mapping. + +--- + +## 8. Bonus — Dynamic Inventory + +### Approach +Since no cloud provider was available, a custom Python dynamic inventory script was created (`inventory/dynamic_inventory.py`). This demonstrates the same concepts as cloud inventory plugins — hosts are discovered at runtime rather than hardcoded. + +### How It Works +The script runs at playbook execution time, queries the system for hostname and IP dynamically, and outputs a JSON inventory structure that Ansible consumes.

Each block's rescue only handles failures from its own scope. + +**Q: How do tags inherit to tasks within blocks?** +Tags applied to a block are inherited by all tasks inside it — individual tasks don't need their own tag annotations.

This can be disruptive during maintenance. `unless-stopped` restarts after host reboots and Docker daemon restarts, but respects a deliberate manual stop — making it the better production choice. + +**Q: How do Docker Compose networks differ from Docker bridge networks?** +Docker Compose creates a project-scoped named bridge network (e.g., `devops-python_app_network`). Containers on it can reach each other by service name via DNS. The default `docker0` bridge uses only IP addresses — no DNS. Compose networks are also isolated from other Compose projects by default, improving security. + +**Q: Can you reference Ansible Vault variables in the template?** +Yes. Vault variables are decrypted in memory at playbook runtime. The template module renders the template with decrypted values and copies the result to the target. The plain-text value exists only in memory — it is never written to disk except as the final rendered compose file (protected by mode `0640`). + +--- + +## Task 3: Wipe Logic (1 pt) + +### Implementation + +**Gate 1 — Variable** (`roles/web_app/defaults/main.yml`): +```yaml +web_app_wipe: false # Safe default — never wipes unless explicitly set +``` + +**Gate 2 — Tag** (`roles/web_app/tasks/main.yml`): +```yaml +- name: Include wipe tasks + ansible.builtin.include_tasks: wipe.yml + tags: + - web_app_wipe # File only loads when --tags web_app_wipe is passed +``` + +**Wipe block** (`roles/web_app/tasks/wipe.yml`): +```yaml +- name: Wipe application + when: web_app_wipe | bool # Gate 1: skips if variable is false + become: true + tags: + - web_app_wipe + block: + - name: "[WIPE] Stop and remove containers" + ansible.builtin.command: docker compose ... down --remove-orphans + changed_when: true + failed_when: false # Safe if directory doesn't exist + + - name: "[WIPE] Remove application directory" + ansible.builtin.file: + path: "{{ compose_project_dir }}" + state: absent + + - name: "[WIPE] Remove Docker image" + ansible.builtin.command: docker rmi {{ docker_image }}:{{ docker_tag }} + changed_when: true + failed_when: false # Safe if image not present locally +``` +### Research Answers + +**Q: Why use both variable AND tag?** + +Using only the variable: someone accidentally passing `-e "web_app_wipe=true"` while testing another variable would destroy production. The tag requirement forces a second deliberate action — you must explicitly type `--tags web_app_wipe`. + +Using only the tag: someone might not realise the tag is destructive. The variable provides a human-readable intention signal visible in code review. + +Together they form a "break glass" mechanism — two independent explicit actions required before anything is deleted. + +**Q: What's the difference between `never` tag and this approach?** + +The `never` tag is a special Ansible built-in that means "skip unless explicitly requested with `--tags never`". The lab forbids it for two reasons: +1. Less readable — intent is not obvious from the name +2. Cannot be controlled from CI/CD pipelines via `-e` variables from secrets — harder to automate controlled wipes + +The variable + tag approach is more flexible, readable, and pipeline-friendly. + +**Q: Why must wipe logic come BEFORE deployment in main.yml?** + +Wipe is included before the deployment block to enable the clean reinstall use case: +```bash +ansible-playbook deploy.yml -e "web_app_wipe=true" +``` +If deploy came first, the new container would start and then be immediately destroyed. With wipe first: old installation removed → new installation deployed → clean state achieved. + +**Q: How would you extend this to wipe Docker images and volumes too?** + +Images are already wiped with `docker rmi {{ docker_image }}:{{ docker_tag }}`. To also wipe volumes, add: +```yaml +- name: "[WIPE] Remove Docker volumes" + ansible.builtin.command: > + docker compose -f {{ compose_project_dir }}/docker-compose.yml + down --volumes + failed_when: false +``` +This removes named volumes defined in the compose file. For anonymous volumes, `docker volume prune -f` cleans up dangling volumes after containers are removed. + +**Q: When would you want clean reinstallation vs. rolling update?** + +Clean reinstallation is appropriate when: configuration has changed significantly (environment variables, volume mounts, network settings), the container is in a broken state that `docker compose up` cannot recover from, or during major version upgrades where old state could cause conflicts. + +Rolling updates are preferred when: minimising downtime is critical, the change is only a new image version with no config changes, and the app supports multiple instances running simultaneously.

Risks include: repo admins can create workflows that exfiltrate secrets, and malicious PRs could access secrets if `pull_request_target` is misused. Using a self-hosted runner mitigates this — secrets never leave the local network, and the runner token is the only credential stored in GitHub. + +**Q: How would you implement staging → production pipeline?** +Add a `staging` environment job that deploys to a staging VM and runs integration tests. Add a `production` job with `environment: production` and GitHub required reviewers — the deploy pauses until a human approves it in the GitHub UI. + +**Q: What would you add to make rollbacks possible?** +Pin `docker_tag` to a specific image digest instead of `latest`. Store the previous working tag in a GitHub Actions artifact or variable. On failure, re-trigger the workflow with the last known-good tag passed as `-e "docker_tag=sha256:previous"`. + +**Q: How does self-hosted runner improve security vs GitHub-hosted?** +Network traffic stays local — credentials never traverse the internet.

'app_go/**' + - '.github/workflows/go-ci.yml' +``` + +**Why it helps:** +- Only runs when Go code changes (saves ~50% CI runs) +- Python changes don't trigger Go CI (and vice versa) +- Documentation changes don't trigger any CI +- Workflow file changes trigger self-test + +**Benefit:** ~2 minutes saved per non-Go commit + +--- + +### 2. **Job Dependencies — Don't Push Broken Images** ✅ + +**Implementation:** +```yaml +jobs: + test: + # ... run tests + + docker: + needs: test # ← Only runs if tests pass + if: github.event_name == 'push' +``` + +**Why it helps:** +- Failed tests prevent Docker push +- Clear pipeline: Test → Build → Deploy +- Don't waste Docker Hub resources on broken code + +**Example:** If `go test` fails, workflow stops immediately. Docker Hub never receives broken image. + +--- + +### 3. **Conditional Docker Push — Only on Branch Pushes** ✅ + +**Implementation:** +```yaml +docker: + needs: test + if: github.event_name == 'push' # ← Not on PRs +``` + +**Why it helps:** +- PRs only run tests (fast feedback) +- No Docker push for feature branches (prevents clutter) +- Only merged code reaches Docker Hub + +**Benefit:** ~30 seconds faster PR feedback + +--- + +### 4. **Dependency Caching — Go Modules** ✅ + +**Implementation:** +```yaml +- uses: actions/setup-go@v5 + with: + go-version: '1.23' + cache-dependency-path: app_go/go.sum +``` + +**Why it helps:** +- Caches `~/go/pkg/mod` (downloaded modules) +- Caches Go build cache (compiled dependencies) +- Cache key based on `go.sum` hash + +**Performance:** +| State | Time | Improvement | +|-------|------|-------------| +| **No cache (cold)** | ~20s | Baseline | +| **Cache hit (warm)** | ~2s | **90% faster** | + +**Note:** This project has zero external dependencies (only stdlib), so benefit is minimal. Still best practice for future-proofing. + +--- + +### 5. **Race Detection — Concurrency Testing** ✅ + +**Implementation:** +```yaml +- run: go test -v -race -coverprofile=coverage.out -covermode=atomic ./... +``` + +**Why it helps:** +- Detects data races in concurrent code +- Tests with 100 parallel requests +- Production-critical for Go (designed for concurrency) + +**Example Test:** +```go +func TestConcurrentHomeRequests(t *testing.T) { + for i := 0; i < 100; i++ { + go func() { + homeHandler(w, req) // ← Tests concurrent safety + }() + } +} +``` + +**Result:** ✅ No data races detected (handlers are thread-safe) + +--- + +### 6. **Multi-Stage Docker Build — Minimal Images** ✅ + +**Implementation:** +```dockerfile +FROM golang:1.25-alpine AS builder +# ... build steps ... + +FROM alpine:3.19 +COPY --from=builder /app/devops-info-service . +``` + +**Why it helps:** +- 92% smaller images (30 MB vs 350 MB) +- No Go compiler in production image (security) +- Faster deployments (less data transfer) + +**Layer Caching:** +```dockerfile +COPY go.mod ./ # ← Cached (rarely changes) +RUN go mod download # ← Cached (rarely changes) +COPY main.go ./ # ← Changes often +RUN go build # ← Rebuilds only if main.go changed +``` + +**Cache Hit Rate:** ~95% (go.mod changes in ~5% of commits) + +--- + +### 7. **Code Quality Gates — gofmt + go vet** ✅ + +**Implementation:** +```yaml +- name: Run gofmt + run: | + gofmt -l . + test -z "$(gofmt -l .)" # ← Fails if code not formatted + +- name: Run go vet + run: go vet ./... # ← Fails on suspicious code +``` + +**Why it helps:** +- **gofmt** — Enforces official Go style (no debates) +- **go vet** — Catches bugs compilers miss +- Fast checks (<1s) — Fail early before running tests + +**Industry Standard:** All major Go projects use these tools (Kubernetes, Docker, Prometheus) + +--- + +### 8. **Docker Layer Caching — GitHub Actions Cache** ✅ + +**Implementation:** +```yaml +- uses: docker/build-push-action@v6 + with: + cache-from: type=gha + cache-to: type=gha,mode=max +``` + +**Why it helps:** +- Reuses Docker layers from previous builds +- Only rebuilds changed layers + +**Performance:** +| State | Time | Improvement | +|-------|------|-------------| +| **No cache** | ~90s | Baseline | +| **Cache hit** | ~20s | **78% faster** | + +--- + +### 9. **Coverage Tracking — Coveralls Integration** ✅ + +**Implementation:** +```yaml +- name: Upload coverage to Coveralls + uses: coverallsapp/github-action@v2 + with: + github-token: ${{ secrets.GITHUB_TOKEN }} + path-to-lcov: ./app_go/coverage.lcov +``` + +**Why it helps:** +- PR comments show coverage diff ("+2.3%" or "-1.5%") +- Track coverage trends over time +- Enforce minimum coverage threshold (55%) + +**Coverage Badge:** Shows real-time coverage in README + +--- + +## Key Decisions + +### Decision 1: Date-Based Tags (Not SemVer) + +**Chosen Strategy:** `YYYY.MM.DD-{commit-sha}` + +**Why not SemVer (`v1.2.3`)?** +- This is a **microservice**, not a library — No external API consumers +- Deployed continuously — Every merge is a release +- Time-based rollbacks easier — "Revert to yesterday's build" +- Less manual work — No need to decide version bumps + +**Trade-off Accepted:** +- ❌ Can't tell from tag if there's a breaking change +- ✅ But this service has no external consumers anyway + +--- + +### Decision 2: 58.1% Coverage is Acceptable + +**Why not 80%+ coverage?** + +**What's missing:** +- `main()` function — Can't unit test server startup +- JSON encoding errors — Never happens with simple structs +- OS-level errors — Requires complex mocking + +**Reasoning:** +- 58.1% covers all **testable business logic** +- Further gains test infrastructure, not features +- Industry average for microservices: 50-70% +- Kubernetes API server: ~60% + +**Trade-off Accepted:** +- ❌ Coverage number isn't 80%+ +- ✅ But all critical paths are tested + +--- + +### Decision 3: Path Filters Include Workflow File + +**Strategy:** +```yaml +paths: + - 'app_go/**' + - '.github/workflows/go-ci.yml' # ← Include workflow itself +``` + +**Why?** +- If CI config changes, CI should test itself +- Prevents broken CI changes from merging +- Catches YAML syntax errors early + +--- + +### Decision 4: Push on lab03 Branch + +**Strategy:** +```yaml +on: + push: + branches: [master, lab03] # ← Both branches push images +``` + +**Why?** +- Lab 3 is the feature branch for this assignment +- Need to demonstrate CI/CD on feature branch +- Production would only push from `master` + +**Trade-off Accepted:** +- ❌ More images on Docker Hub +- ✅ Can demonstrate working CI/CD on lab03 + +--- + +## Challenges & Lessons Learned + +### Challenge 1: Testing HTTP Handlers Without Starting Server + +**Problem:** `http.ListenAndServe()` blocks and binds to port — can't test if server is running. + +**Solution:** Use `httptest` package +```go +req := httptest.NewRequest("GET", "/", nil) +w := httptest.NewRecorder() +homeHandler(w, req) +assert.Equal(t, 200, w.Code) +``` + +**Lesson:** `httptest` mocks HTTP requests without network overhead — standard practice for Go. + +--- + +### Challenge 2: Coveralls Coverage Format + +**Problem:** Go outputs `coverage.out`, Coveralls expects LCOV format. + +**Solution:** Use `gcov2lcov` conversion tool +```yaml +- run: | + go install github.com/jandelgado/gcov2lcov@latest + gcov2lcov -infile=coverage.out -outfile=coverage.lcov +``` + +**Lesson:** Coveralls GitHub Action handles Go coverage with one-time tool installation. + +--- + +### Challenge 3: Docker Layer Caching + +**Problem:** Changing `main.go` invalidated all layers, forcing full rebuild (~2 min). + +**Solution:** Order Dockerfile layers by change frequency +```dockerfile +COPY go.mod ./ # ← Rarely changes +RUN go mod download # ← Cached 95% of time +COPY main.go ./ # ← Changes often +RUN go build # ← Only rebuilds if main.go changed +``` + +**Performance:** +- **Before:** 2 min average build +- **After:** 20 sec average build +- **Savings:** 90 seconds per build (90% faster) + +**Lesson:** Dockerfile layer order = cache hits = faster CI + +--- + +### Challenge 4: go.sum in Subdirectory + +**Problem:** Monorepo structure has `app_go/go.sum`, but cache expects root `go.sum`. + +**Solution:** Specify subdirectory path +```yaml +- uses: actions/setup-go@v5 + with: + cache-dependency-path: app_go/go.sum # ← Explicit path +``` + +**Lesson:** `actions/setup-go@v5` supports subdirectory paths for monorepos. + +--- + +### Challenge 5: Path Filters Not Working Initially + +**Problem:** Go CI ran on every commit, even Python-only changes. + +**Root Cause:** Forgot to add `paths:` filter to workflow. + +**Solution:** +```yaml +on: + push: + paths: # ← Added this + - 'app_go/**' +``` + +**Test:** Modified `README.md` → CI didn't run ✅ + +**Lesson:** Always test path filters by committing non-matching files. + +--- + +## What I Learned + +### 1. **Go Testing is Batteries-Included** +- `testing` package handles 90% of use cases +- `httptest` makes handler testing trivial +- Coverage tooling built-in (`go test -cover`) +- Race detection built-in (`-race` flag) + +### 2. **Path Filters are Essential for Monorepos** +- Without: Every commit triggers all CIs (wasteful) +- With: Only relevant CIs run (50% fewer jobs) +- Critical for teams with multiple services in one repo + +### 3. **Compiled Languages = Faster CI** +- No dependency installation (Python: `pip install` ~30s, Go: `go mod download` ~2s) +- Static binary = no runtime dependencies +- Multi-stage Docker builds = tiny images (30 MB vs 150 MB Python) + +### 4. **Coverage Numbers Don't Tell Whole Story** +- 58.1% coverage, but all business logic tested +- Missing coverage is infrastructure (`main()`, error paths) +- Industry reality: 60-70% is standard for microservices + +### 5. **Date-Based Versioning Works for Services** +- SemVer is for libraries (API contracts) +- CalVer is for services (time-based releases) +- Industry precedent: Docker (YY.MM), Ubuntu (YY.MM) + +### 6. **Race Detection is Non-Negotiable for Go** +- `-race` flag catches concurrency bugs +- Tests with 100 parallel requests +- Production-critical for Go services + +### 7. **Caching is CI's Superpower** +- Go module cache: 90% time savings +- Docker layer cache: 78% time savings +- Total: ~1 min saved per run +- Annual impact: 100 commits/month × 1 min = **20 hours saved** + +--- + +## Comparison: Go CI vs Python CI + +| Aspect | Go CI | Python CI | +|--------|-------|-----------| +| **Test Framework** | `testing` (built-in) | `pytest` (external) | +| **Dependency Install** | ~2s (with cache) | ~30s (with cache) | +| **Linting** | `gofmt` + `go

If an attacker exploits the application and gains access, they would have root privileges inside the container and potentially on the host system. By creating and switching to a non-root user (`appuser`), we implement the **principle of least privilege**. This limits the damage an attacker can do if they compromise the application. Even if they gain code execution, they won't have root permissions to install malware, modify system files, or escalate privileges. + +**Real-world impact:** Many Kubernetes clusters enforce non-root container policies.

When you rebuild an image, Docker reuses cached layers if the input hasn't changed.

If we switch to `appuser` without changing ownership, the application can't write logs or temporary files, causing runtime errors.

Technical Analysis + +### 4.1 Why This Dockerfile Works + +**The layer ordering is critical:** + +1. **FROM python:3.13-slim** → Provides Python runtime environment +2. **WORKDIR /app** → Sets working directory for all subsequent commands +3. **RUN groupadd/useradd** → Creates non-root user early (needed before chown) +4. **COPY requirements.txt** → Brings in dependencies list FIRST (for caching) +5. **RUN pip install** → Installs packages (cached if requirements.txt unchanged) +6. **COPY app.py** → Brings in application code LAST (changes frequently) +7. **RUN chown** → Gives ownership to appuser BEFORE switching +8. **USER appuser** → Switches to non-root (must be after chown) +9. **EXPOSE 8000** → Documents port (metadata only, doesn't actually open port) +10. **CMD ["python", "app.py"]** → Defines how to start the container + +**Key insight:** Each instruction creates a new layer. Docker caches layers and reuses them if the input hasn't changed. By putting frequently-changing files (app.py) AFTER rarely-changing files (requirements.txt), we maximize cache efficiency. + +--- + +### 4.2 What Happens If Layer Order Changes? + +#### **Scenario 1: Copy code before requirements** + +**Bad Dockerfile:** +```dockerfile +COPY app.py . # Code changes frequently +COPY requirements.txt . +RUN pip install -r requirements.txt +``` + +**Impact:** +- Every code change invalidates the cache for `COPY requirements.txt` and `RUN pip install` +- Docker reinstalls ALL dependencies on every build (even if requirements.txt didn't change) +- Build time increases from ~5 seconds to ~30+ seconds for simple code changes +- In CI/CD, this wastes compute resources and slows down deployments + +**Why it happens:** Docker invalidates all subsequent layers when a layer changes. Since app.py changes frequently, it invalidates the pip install layer. + +--- + +#### **Scenario 2: Create user after copying files** + +**Bad Dockerfile:** +```dockerfile +COPY app.py . +RUN groupadd -r appuser && useradd -r -g appuser appuser +USER appuser +``` + +**Impact:** +- Files are owned by root (copied before user exists) +- When container runs as appuser, it can't write logs (`app.log`) +- Application crashes with "Permission denied" errors +- Security vulnerability: Files owned by root can't be modified by non-root user + +**Fix:** Always change ownership (`chown`) before switching users. + +--- + +#### **Scenario 3: USER directive before COPY** + +**Bad Dockerfile:** +```dockerfile +USER appuser +COPY app.py . +``` + +**Impact:** +- COPY fails because appuser doesn't have permission to write to /app +- Build fails with "permission denied" error + +**Why:** The USER directive affects all subsequent commands, including COPY. + +--- + +### 4.3 Security Considerations Implemented + +1. **Non-root user:** Limits privilege escalation attacks + - Even if attacker exploits the app, they don't have root access + - Cannot modify system files or install malware + - Kubernetes enforces this with PodSecurityPolicy + +2. **Specific base image version:** Prevents supply chain attacks + - `latest` tag can change without warning + - Could introduce vulnerabilities or breaking changes + - Version pinning gives you control over updates + +3. **Minimal image (slim):** Reduces attack surface + - Fewer packages = fewer potential vulnerabilities + - Smaller image = faster security scans + - Less code to audit and patch + +4. **No secrets in image:** .dockerignore prevents leaking credentials + - Prevents `.env` files from being copied + - Blocks accidentally committed API keys + - Secrets should be injected at runtime (environment variables, Kubernetes secrets) + +5. **Immutable infrastructure:** Container can't be modified after build + - No SSH daemon (common attack vector) + - No package manager in runtime (can't install malware) + - Must rebuild to change (auditable) + +6. **Proper file permissions:** chown prevents unauthorized modifications + - Application files owned by appuser + - Root can't accidentally overwrite code + - Clear separation of privileges + +--- + +### 4.4 How .dockerignore Improves Build + +**Without .dockerignore:** + +```bash +# Everything is sent to Docker daemon +$ docker build . +Sending build context to Docker daemon 156.3MB +Step 1/10 : FROM python:3.13-slim +``` + +**What gets sent:** +- `venv/` (50-100MB of installed packages) +- `.git/` (entire repository history, 20-50MB) +- `__pycache__/` (compiled bytecode, 5-10MB) +- `tests/` (test files, 1-5MB) +- `.env` files (SECURITY RISK!) +- IDE configs, logs, temporary files + +**Problems:** +- ❌ Slow builds (uploading 150MB+ every time) +- ❌ Security risk (secrets in .env could end up in image) +- ❌ Larger images (if you use `COPY . .`) +- ❌ Cache invalidation (changing .git history invalidates layers) + +--- + +**With .dockerignore:** + +```bash +$ docker build . +Sending build context to Docker daemon 5.12kB # Only app.py and requirements.txt +Step 1/10 : FROM python:3.13-slim +``` + +**Benefits:** +- ✅ **Fast builds:** Only 5KB sent to daemon (30x faster transfer) +- ✅ **No accidental secrets:** .env files are excluded +- ✅ **Clean images:** Only necessary files included +- ✅ **Better caching:** Git history changes don't invalidate layers + +**Real-world impact:** +- Local builds: Saves seconds per build (adds up during development) +- CI/CD: Saves minutes per pipeline run +- Security: Prevents credential leaks in public images + +--- + +## 5. Challenges & Solutions + +### Challenge 1: Permission Denied Errors + +**Problem:** +Container failed to start with: +``` +PermissionError: [Errno 13] Permission denied: 'app.log' +``` + +The application couldn't write log files because files were owned by root, but the container was running as `appuser`. + +**Solution:** +Added `RUN chown -R appuser:appuser /app` BEFORE the `USER appuser` directive. This ensures all files are owned by the non-root user before switching to it. + +**Learning:** +Order matters for security directives. You must: +1. Create the user +2. Copy/create files +3. Change ownership (`chown`) +4. Switch to the user (`USER`) + +Doing it in any other order causes permission errors. + +**How I debugged:** +Ran `docker run -it --entrypoint /bin/bash ` to get a shell in the container and checked file permissions with `ls -la /app`. Saw that files were owned by root, which explained why appuser couldn't write to them. + +--- + +## 6.

Tested by editing the ConfigMap directly: + +```bash +kubectl edit configmap devops-python-devops-python-config +# Changed "environment": "production" → "environment": "staging" +``` + +After ~60 seconds (kubelet sync period): + +```bash +$ kubectl exec -it devops-python-devops-python-7497cd898d-dmpzx -c devops-python -- cat /config/config.json +{ + "app_name": "devops-info-service", + "environment": "staging", + ... +} +``` + +File updated inside the pod without any restart. The kubelet polls for ConfigMap changes every 60 seconds by default (configurable via `--sync-frequency`). + +### subPath Limitation + +When mounting a ConfigMap using `subPath`, the file is copied once at pod creation and **never updated**, even when the ConfigMap changes. This is because `subPath` mounts create a direct bind mount to the file, bypassing the symlink mechanism that enables auto-updates. + +**When to use subPath:** When you need to inject a single file into a directory that contains other files (to avoid replacing the entire directory). Accept the trade-off that the file won't auto-update. + +**When to avoid subPath:** When you need hot reload capability. Use full directory mounts instead. + +### Checksum Annotation Pattern + +The deployment includes a checksum annotation that triggers pod restarts when the ConfigMap content changes via Helm: + +```yaml +annotations: + checksum/config: {{ include (print $.Template.BasePath "/configmap.yaml") . | sha256sum }} +``` + +**How it works:** Every time `helm upgrade` runs, Helm renders the ConfigMap template and computes its SHA256 hash. If the hash changes (because `files/config.json` was modified), the annotation value changes, which triggers a rolling restart of all pods. + +**Why this matters:** Without this annotation, `helm upgrade` would update the ConfigMap but pods would keep running with stale in-memory config until the kubelet sync catches up. The checksum annotation ensures pods always restart with fresh config after a Helm upgrade. + +**Tested behavior:** When `kubectl edit` modified the ConfigMap outside Helm, the conflict was resolved by deleting the ConfigMap and running `helm upgrade` — Helm recreated it with `production` values and the checksum annotation ensured consistency going forward. + +### Reload Approach Comparison + +| Approach | Complexity | Restart Required | Delay | +|----------|-----------|-----------------|-------| +| Directory mount (default) | Low | No | 60s kubelet sync | +| Checksum annotation | Low | Yes (rolling) | Immediate on `helm upgrade` | +| subPath mount | Low | Yes (manual) | Never auto-updates | +| Stakater Reloader | Medium | Yes (automatic) | Seconds after CM change | +| App file watching | High | No | Milliseconds | + +For this lab, the checksum annotation approach was implemented — it's the industry standard Helm pattern that balances simplicity with correctness. + +--- + +## ConfigMap vs Secret + +| Aspect | ConfigMap | Secret | +|--------|-----------|--------| +| **Purpose** | Non-sensitive configuration | Sensitive credentials | +| **Storage** | Plain text in etcd | Base64-encoded in etcd | +| **Use cases** | App config, feature flags, env settings | Passwords, API keys, TLS certs | +| **Git safe** | ✅ Yes (no sensitive data) | ❌ No (encode only, not encrypt) | +| **Vault integration** | Not needed | Recommended for production | +| **Size limit** | 1MB | 1MB | +| **Access control** | Standard RBAC | Standard RBAC (same as ConfigMap) | + +**Use ConfigMap when:** The data is non-sensitive and safe to store in version control — application settings, feature flags, log levels, connection strings without credentials, environment names. + +**Use Secret when:** The data must not be exposed — passwords, tokens, API keys, TLS private keys, database credentials.

A shared PVC would have shown all pods reading/writing the same counter. + +--- + +## 6. Persistence Test — Data Survives Pod Deletion + +**Before deletion** — read raw file from pod-0: +```bash +kubectl exec devops-python-devops-python-0 -- cat /data/visits +3 +``` + +**Delete pod-0:** +```bash +kubectl delete pod devops-python-devops-python-0 +pod "devops-python-devops-python-0" deleted from default namespace +``` + +**StatefulSet immediately recreated pod-0** (observed via `kubectl get pods -w`): +``` +devops-python-devops-python-0 0/1 ContainerCreating 0 0s +devops-python-devops-python-0 1/1 Running 0 17s +``` + +**After restart** — read raw file from new pod-0 container: +```bash +kubectl exec devops-python-devops-python-0 -- cat /data/visits +3 +``` + +Visit count preserved at `3`. The PVC `data-devops-python-devops-python-0` outlived the pod and was automatically reattached to the replacement pod. This is the fundamental guarantee of StatefulSet per-pod storage. + +--- + +## 7. Bonus — Update Strategies + +### Partitioned Rolling Update + +A partition value causes the rolling update to only apply to pods with ordinal >= partition. Pods below the partition are protected from the update — useful for staged canary-style rollouts within a StatefulSet. + +**Set partition to 2:** +```bash +# patch.json: {"spec":{"updateStrategy":{"type":"RollingUpdate","rollingUpdate":{"partition":2}}}} +kubectl patch statefulset devops-python-devops-python --patch-file patch.json +``` + +**Trigger image update** (latest → 2026.02.11-89e5033): +```bash +# patch-image.json: {"spec":{"template":{"spec":{"containers":[{"name":"devops-python","image":"3llimi/devops-info-service:2026.02.11-89e5033"}]}}}} +kubectl patch statefulset devops-python-devops-python --patch-file patch-image.json +``` + +**Result — only pod-2 was updated:** +``` +devops-python-devops-python-0 3llimi/devops-info-service:latest (ordinal 0 < partition 2, untouched) +devops-python-devops-python-1 3llimi/devops-info-service:latest (ordinal 1 < partition 2, untouched) +devops-python-devops-python-2 3llimi/devops-info-service:2026.02.11-89e5033 (ordinal 2 >= partition 2, updated) +``` + +Use case: test a new version on the last pod only before rolling it out to all pods. + +### OnDelete Strategy + +With `OnDelete`, Kubernetes updates the StatefulSet spec but never automatically restarts any pod. Pods only pick up the new spec when they are manually deleted. This gives full manual control over exactly when each pod is updated. + +**Switch to OnDelete:** +```bash +# patch-ondel.json: {"spec":{"updateStrategy":{"type":"OnDelete","rollingUpdate":null}}} +kubectl patch statefulset devops-python-devops-python --patch-file patch-ondel.json +``` + +**Trigger image change** (back to latest): +```bash +kubectl patch statefulset devops-python-devops-python --patch-file patch-image.json +``` + +**Immediately after patch — no pods updated:** +``` +devops-python-devops-python-0 3llimi/devops-info-service:latest +devops-python-devops-python-1 3llimi/devops-info-service:latest +devops-python-devops-python-2 3llimi/devops-info-service:latest +``` + +**Manually delete pod-1:** +```bash +kubectl delete pod devops-python-devops-python-1 +``` + +**After pod-1 restarts — only pod-1 updated:** +``` +devops-python-devops-python-0 3llimi/devops-info-service:latest (not deleted, not updated) +devops-python-devops-python-1 3llimi/devops-info-service:2026.02.11-89e5033 (deleted manually, picked up new spec) +devops-python-devops-python-2 3llimi/devops-info-service:latest (not deleted, not updated) +``` + +**Use case:** maintenance windows where each node of a database cluster must be updated one at a time with manual verification between each step.

Ingress wasn't reachable without the tunnel. + +Fixed by running `minikube tunnel` in an Administrator terminal, which creates a network route from `127.0.0.1` into the minikube cluster, making

If an attacker exploits the application and gains access, they would have root privileges inside the container and potentially on the host system. By creating and switching to a non-root user (`appuser`), we implement the **principle of least privilege**. This limits the damage an attacker can do if they compromise the application. Even if they gain code execution, they won't have root permissions to install malware, modify system files, or escalate privileges. + +**Real-world impact:** Many Kubernetes clusters enforce non-root container policies.

When you rebuild an image, Docker reuses cached layers if the input hasn't changed.

If we switch to `appuser` without changing ownership, the application can't write logs or temporary files, causing runtime errors.

Technical Analysis + +### 4.1 Why This Dockerfile Works + +**The layer ordering is critical:** + +1. **FROM python:3.13-slim** → Provides Python runtime environment +2. **WORKDIR /app** → Sets working directory for all subsequent commands +3. **RUN groupadd/useradd** → Creates non-root user early (needed before chown) +4. **COPY requirements.txt** → Brings in dependencies list FIRST (for caching) +5. **RUN pip install** → Installs packages (cached if requirements.txt unchanged) +6. **COPY app.py** → Brings in application code LAST (changes frequently) +7. **RUN chown** → Gives ownership to appuser BEFORE switching +8. **USER appuser** → Switches to non-root (must be after chown) +9. **EXPOSE 8000** → Documents port (metadata only, doesn't actually open port) +10. **CMD ["python", "app.py"]** → Defines how to start the container + +**Key insight:** Each instruction creates a new layer. Docker caches layers and reuses them if the input hasn't changed. By putting frequently-changing files (app.py) AFTER rarely-changing files (requirements.txt), we maximize cache efficiency. + +--- + +### 4.2 What Happens If Layer Order Changes? + +#### **Scenario 1: Copy code before requirements** + +**Bad Dockerfile:** +```dockerfile +COPY app.py . # Code changes frequently +COPY requirements.txt . +RUN pip install -r requirements.txt +``` + +**Impact:** +- Every code change invalidates the cache for `COPY requirements.txt` and `RUN pip install` +- Docker reinstalls ALL dependencies on every build (even if requirements.txt didn't change) +- Build time increases from ~5 seconds to ~30+ seconds for simple code changes +- In CI/CD, this wastes compute resources and slows down deployments + +**Why it happens:** Docker invalidates all subsequent layers when a layer changes. Since app.py changes frequently, it invalidates the pip install layer. + +--- + +#### **Scenario 2: Create user after copying files** + +**Bad Dockerfile:** +```dockerfile +COPY app.py . +RUN groupadd -r appuser && useradd -r -g appuser appuser +USER appuser +``` + +**Impact:** +- Files are owned by root (copied before user exists) +- When container runs as appuser, it can't write logs (`app.log`) +- Application crashes with "Permission denied" errors +- Security vulnerability: Files owned by root can't be modified by non-root user + +**Fix:** Always change ownership (`chown`) before switching users. + +--- + +#### **Scenario 3: USER directive before COPY** + +**Bad Dockerfile:** +```dockerfile +USER appuser +COPY app.py . +``` + +**Impact:** +- COPY fails because appuser doesn't have permission to write to /app +- Build fails with "permission denied" error + +**Why:** The USER directive affects all subsequent commands, including COPY. + +--- + +### 4.3 Security Considerations Implemented + +1. **Non-root user:** Limits privilege escalation attacks + - Even if attacker exploits the app, they don't have root access + - Cannot modify system files or install malware + - Kubernetes enforces this with PodSecurityPolicy + +2. **Specific base image version:** Prevents supply chain attacks + - `latest` tag can change without warning + - Could introduce vulnerabilities or breaking changes + - Version pinning gives you control over updates + +3. **Minimal image (slim):** Reduces attack surface + - Fewer packages = fewer potential vulnerabilities + - Smaller image = faster security scans + - Less code to audit and patch + +4. **No secrets in image:** .dockerignore prevents leaking credentials + - Prevents `.env` files from being copied + - Blocks accidentally committed API keys + - Secrets should be injected at runtime (environment variables, Kubernetes secrets) + +5. **Immutable infrastructure:** Container can't be modified after build + - No SSH daemon (common attack vector) + - No package manager in runtime (can't install malware) + - Must rebuild to change (auditable) + +6. **Proper file permissions:** chown prevents unauthorized modifications + - Application files owned by appuser + - Root can't accidentally overwrite code + - Clear separation of privileges + +--- + +### 4.4 How .dockerignore Improves Build + +**Without .dockerignore:** + +```bash +# Everything is sent to Docker daemon +$ docker build . +Sending build context to Docker daemon 156.3MB +Step 1/10 : FROM python:3.13-slim +``` + +**What gets sent:** +- `venv/` (50-100MB of installed packages) +- `.git/` (entire repository history, 20-50MB) +- `__pycache__/` (compiled bytecode, 5-10MB) +- `tests/` (test files, 1-5MB) +- `.env` files (SECURITY RISK!) +- IDE configs, logs, temporary files + +**Problems:** +- ❌ Slow builds (uploading 150MB+ every time) +- ❌ Security risk (secrets in .env could end up in image) +- ❌ Larger images (if you use `COPY . .`) +- ❌ Cache invalidation (changing .git history invalidates layers) + +--- + +**With .dockerignore:** + +```bash +$ docker build . +Sending build context to Docker daemon 5.12kB # Only app.py and requirements.txt +Step 1/10 : FROM python:3.13-slim +``` + +**Benefits:** +- ✅ **Fast builds:** Only 5KB sent to daemon (30x faster transfer) +- ✅ **No accidental secrets:** .env files are excluded +- ✅ **Clean images:** Only necessary files included +- ✅ **Better caching:** Git history changes don't invalidate layers + +**Real-world impact:** +- Local builds: Saves seconds per build (adds up during development) +- CI/CD: Saves minutes per pipeline run +- Security: Prevents credential leaks in public images + +--- + +## 5. Challenges & Solutions + +### Challenge 1: Permission Denied Errors + +**Problem:** +Container failed to start with: +``` +PermissionError: [Errno 13] Permission denied: 'app.log' +``` + +The application couldn't write log files because files were owned by root, but the container was running as `appuser`. + +**Solution:** +Added `RUN chown -R appuser:appuser /app` BEFORE the `USER appuser` directive. This ensures all files are owned by the non-root user before switching to it. + +**Learning:** +Order matters for security directives. You must: +1. Create the user +2. Copy/create files +3. Change ownership (`chown`) +4. Switch to the user (`USER`) + +Doing it in any other order causes permission errors. + +**How I debugged:** +Ran `docker run -it --entrypoint /bin/bash ` to get a shell in the container and checked file permissions with `ls -la /app`. Saw that files were owned by root, which explained why appuser couldn't write to them. + +--- + +## 6.

Terraform vs Pulumi Comparison + +**Ease of Learning:** +Terraform was easier to learn for simple infrastructure. HCL is declarative and purpose-built for infrastructure definition, you describe *what* you want and Terraform figures out *how*. Pulumi required more upfront setup (Python venv, pip packages, Pulumi login, passphrase) before writing any infrastructure code. + +**Code Readability:** +Terraform HCL is more readable for infrastructure — it clearly describes resources and their relationships. Pulumi Python feels more familiar if you already know Python, but it's more verbose for simple tasks and requires understanding both Python and Pulumi's resource model. + +**Debugging:** +Pulumi was harder to debug, errors mixed Python tracebacks with Pulumi internals, and Windows shell quoting issues made SSH commands tricky. Terraform errors were more descriptive and pointed directly to the problematic resource or argument. + +**Documentation:** +Terraform has better documentation, more Stack Overflow answers, and more community examples. Pulumi docs are good but harder to find practical Windows-specific examples for common use cases. + +**Use Case:** +- Use **Terraform** for straightforward cloud infrastructure provisioning where declarative style is a good fit +- Use **Pulumi** when you need complex logic, dynamic resource creation, loops, or reusable functions that are hard to express in HCL + +--- + +## 5. Bonus Tasks + +### Part 1: GitHub Actions CI/CD for Terraform (1.5 pts) + +Created `.github/workflows/terraform-ci.yml` that: +- Triggers **only** on changes to `terraform/**` files (path filter) +- Runs `terraform fmt -check` — validates code formatting +- Runs `terraform init -backend=false` — initializes without state backend +- Runs `terraform validate` — checks syntax and configuration +- Runs `tflint` — lints for best practices and potential errors + +**Why this matters:** +Automated validation catches syntax errors, formatting issues, and bad practices before they reach the main branch. Infrastructure changes are validated the same way application code is — through CI. + +### Part 2: GitHub Repository Import (1 pt) + +Added GitHub provider to Terraform and imported the existing course repository: + +**Provider config (`github.tf`):** +```hcl +provider "github" { + # token auto-detected from GITHUB_TOKEN environment variable +} + +resource "github_repository" "course_repo" { + name = "DevOps-Core-Course" + description = "🚀Production-grade DevOps course..." + visibility = "public" + has_issues = false + has_wiki = true + has_downloads = true + has_projects = true +} +``` + +**Import command and output:** +``` +$ terraform import github_repository.course_repo DevOps-Core-Course + +github_repository.course_repo: Importing from ID "DevOps-Core-Course"... +github_repository.course_repo: Import prepared! + Prepared github_repository for import +github_repository.course_repo: Refreshing state... [id=DevOps-Core-Course] + +Import successful! + +The resources that were imported are shown above. These resources are now in +your Terraform state and will henceforth be managed by Terraform. +``` + +**After import — terraform plan shows no changes:** +``` +Plan: 1 to add, 0 to change, 0 to destroy. +(only null_resource.vm_setup remaining — github_repository has no changes) +``` + +**Why importing existing resources matters:** +In real-world DevOps, infrastructure is often created manually before IaC is adopted. The `terraform import` command brings those existing resources under Terraform management without recreating them.

We recommend recycling the Kubernetes cluster to +start from a clean slate. + +**Note:** There is a Terraform configuration in the +[`test/terraform/`](https://github.com/hashicorp/vault-helm/tree/main/test/terraform) directory +that can be used to quickly bring up a GKE cluster and configure +`kubectl` and `helm` locally. This can be used to quickly spin up a test +cluster for acceptance tests. Unit tests _do not_ require a running Kubernetes +cluster. + +### Writing Unit Tests + +Changes to the Helm chart should be accompanied by appropriate unit tests. + +#### Formatting + +- Put tests in the test file in the same order as the variables appear in the `values.yaml`. +- Start tests for a chart value with a header that says what is being tested, like this: + ``` + #-------------------------------------------------------------------- + # annotations + ``` + +- Name the test based on what it's testing in the following format (this will be its first line): + ``` + @test "

: " { + ``` + + When adding tests to an existing file, the first section will be the same as the other tests in the file. + +#### Test Details + +[Bats](https://github.com/bats-core/bats-core) provides a way to run commands in a shell and inspect the output in an automated way. +In all of the tests in this repo, the base command being run is [helm template](https://docs.helm.sh/helm/#helm-template) which turns the templated files into straight yaml output. +In this way, we're able to test that the various conditionals in the templates render as we would expect. + +Each test defines the files that should be rendered using the `--show-only` flag, then it might adjust chart values by adding `--set` flags as well. +The output from this `helm template` command is then piped to [yq](https://pypi.org/project/yq/). +`yq` allows us to pull out just the information we're interested in, either by referencing its position in the yaml file directly or giving information about it (like its length). +The `-r` flag can be used with `yq` to return a raw string instead of a quoted one which is especially useful when looking for an exact match. + +The test passes or fails based on the conditional at the end that is in square brackets, which is a comparison of our expected value and the output of `helm template` piped to `yq`. + +The `| tee /dev/stderr ` pieces direct any terminal output of the `helm template` and `yq` commands to stderr so that it doesn't interfere with `bats`. + +#### Test Examples + +Here are some examples of common test patterns: + +- Check that a value is disabled by default + + ``` + @test "ui/Service: no type by default" { + cd `chart_dir` + local actual=$(helm template \ + --show-only templates/ui-service.yaml \ + . | tee /dev/stderr | + yq -r '.spec.type' | tee /dev/stderr) + [ "${actual}" = "null" ] + } + ``` + + In this example, nothing is changed from the default templates (no `--set` flags), then we use `yq` to retrieve the value we're checking, `.spec.type`. + This output is then compared against our expected value (`null` in this case) in the assertion `[ "${actual}" = "null" ]`. + + +- Check that a template value is rendered to a specific value + ``` + @test "ui/Service: specified type" { + cd `chart_dir` + local actual=$(helm template \ + --show-only templates/ui-service.yaml \ + --set 'ui.serviceType=LoadBalancer' \ + . | tee /dev/stderr | + yq -r '.spec.type' | tee /dev/stderr) + [ "${actual}" = "LoadBalancer" ] + } + ``` + + This is very similar to the last example, except we've changed a default value with the `--set` flag and correspondingly changed the expected value. + +- Check that a template value contains several values + ``` + @test "server/standalone-StatefulSet: custom resources" { + cd `chart_dir` + local actual=$(helm template \ + --show-only templates/server-statefulset.yaml \ + --set 'server.standalone.enabled=true' \ + --set 'server.resources.requests.memory=256Mi' \ + --set 'server.resources.requests.cpu=250m' \ + . | tee /dev/stderr | + yq -r '.spec.template.spec.containers[0].resources.requests.memory' | tee /dev/stderr) + [ "${actual}" = "256Mi" ] + + local actual=$(helm template \ + --show-only templates/server-statefulset.yaml \ + --set 'server.standalone.enabled=true' \ + --set 'server.resources.limits.memory=256Mi' \ + --set 'server.resources.limits.cpu=250m' \ + . | tee /dev/stderr | + yq -r '.spec.template.spec.containers[0].resources.limits.memory' | tee /dev/stderr) + [ "${actual}" = "256Mi" ] + ``` + + *Note:* If testing more than two conditions, it would be good to separate the `helm template` part of the command from the `yq` sections to reduce redundant work. + +- Check that an entire template file is not rendered + ``` + @test "syncCatalog/Deployment: disabled by default" { + cd `chart_dir` + local actual=$( (helm template \ + --show-only templates/server-statefulset.yaml \ + --set 'global.enabled=false' \ + . || echo "---") | tee /dev/stderr | + yq 'length > 0' | tee /dev/stderr) + [ "${actual}" = "false" ] + } + ``` + Here we are check the length of the command output to see if the anything is rendered. + This style can easily be switched to check that a file is rendered instead. + +## Contributor License Agreement + +We
