# Lab 3 — CI/CD with GitHub Actions
2+
3+
## Task 1
4+
5+
### What I did:
6+
1. Created `.github/workflows/ci.yml` file
7+
2. Configured trigger on push to "Feature/lab3" branch
8+
3. Added basic steps to print "Hello World"
9+
10+

12+
13+
### Key concepts learned:
14+
- **Workflow** — automated process defined in YAML file
15+
- **Jobs** — set of steps that execute on the same runner
16+
- **Steps** — individual commands or actions within a job
17+
- **Runners** — GitHub-hosted virtual machines (ubuntu-latest)
18+
- **Triggers** — events that start workflow (push, workflow_dispatch)
19+
20+
### What triggered the run:
21+
Push commit to `Feature/lab3` branch triggered the workflow automatically.

## Task 2
26+
27+
### Changes made to workflow:
28+
- Added `workflow_dispatch` event to enable manual triggering
29+
- Added "System Information" step to collect runner details
30+

### Comparison of manual vs automatic triggers:
109+
110+
| Type | How it triggers | Use case |
111+
|------|-----------------|----------|
112+
| Automatic (push) | On every push to branch | CI — code validation, testing |
113+
| Manual (workflow_dispatch) | Button click in GitHub UI | Deployments, releases, debugging |
114+
115+
### Runner environment analysis:
116+
- **OS:** Ubuntu 24.04.3 LTS (Noble Numbat)
117+
- **CPU:** AMD EPYC 7763 64-Core Processor, 4 vCPUs (2 cores × 2 threads)
118+
- **RAM:** 15 GB total, ~13 GB available
119+
- **Disk:** 145 GB total, 92 GB available
120+
- **Virtualization:** Microsoft Azure (AMD-V)
121+
122+
GitHub-hosted runners provide powerful virtual machines with pre-installed development tools, making them suitable for most CI/CD tasks.
