+      - "80:80/tcp"  # Web管理界面
+      - "443:443/tcp"


adguard publishes 80/443 to the host, but nginx-proxy-manager also publishes 80/443 in the same compose file. Docker will fail to start one of the containers due to port binding conflicts. Use unique host ports (e.g. map AdGuard UI to 3001/8443, or only expose one service on 80/443) and route everything else via the shared reverse proxy network.

Suggested change

- "80:80/tcp" # Web管理界面

- "443:443/tcp"

- "3001:80/tcp" # Web管理界面（通过主机端口 3001 访问）

- "8443:443/tcp" # HTTPS Web 管理界面（通过主机端口 8443 访问）

+      - "81:81"      # 管理界面
+      - "80:80"      # HTTP
+      - "443:443"    # HTTPS


This stack binds 80:80 and 443:443 for Nginx Proxy Manager, which will conflict with the base Traefik stack (also binds 80/443) and with AdGuard in this same compose. If this repo expects Traefik as the single edge proxy, NPM should not bind host 80/443 (run it behind Traefik and only expose the admin UI), or explicitly document that Traefik must be stopped.

Suggested change

- "81:81" # 管理界面

- "80:80" # HTTP

- "443:443" # HTTPS

- "81:81" # 管理界面（仅暴露管理端口；HTTP/HTTPS 由 Traefik/其他反向代理处理）

+      - WG_ALLOWED_IPS=0.0.0.0/0, ::/0


WG_DEFAULT_DNS is set to 172.20.0.2 with a comment implying it's the AdGuard Home IP, but adguard (and unbound) do not have static IPs assigned—only wireguard does. This makes the DNS setting non-deterministic across restarts. Prefer using the service name (adguard) for DNS where supported, or assign fixed ipv4_address values to adguard/unbound in the network-stack network.

+    ports:
+      - "5353:53/tcp"
+      - "5353:53/udp"
+    volumes:
+      - ./unbound/unbound.conf:/etc/unbound/unbound.conf
+      - ./unbound/cache:/var/cache/unbound
    networks:


unbound is published on host port 5353 (5353:53) while the Unbound config allows queries from 0.0.0.0/0/::/0. This effectively exposes a recursive resolver on the host, which is a common abuse vector (open resolver). If Unbound is only meant as AdGuard’s upstream, remove the host ports: mapping and keep it internal to the Docker network, or restrict access-control to only the Docker subnet.

+    healthcheck:
+      test: ["CMD", "sh", "-c", "echo 'Health check passed'"]
+      interval: 60s
+      timeout: 10s
+      retries: 3


The cloudflare-ddns healthcheck always succeeds (echo 'Health check passed'), so it won’t detect crashes or misconfiguration (e.g., missing API token). Replace this with a real liveness check (process/HTTP endpoint if available) or remove the healthcheck to avoid giving a false sense of health.

Suggested change

healthcheck:

test: ["CMD", "sh", "-c", "echo 'Health check passed'"]

interval: 60s

timeout: 10s

+### 3. Access the services
+
+- **ntfy Web UI**: https://ntfy.your-domain.com
+- **Gotify Web UI**: http://your-server:8080


The README says Gotify is reachable at http://your-server:8080, but the compose file does not publish port 8080 on the host; it’s only reachable via Traefik on the proxy network. Update the access instructions to match the actual exposure (e.g., https://gotify.${DOMAIN} via Traefik) or add an explicit ports: mapping if host access is intended.

Suggested change

- **Gotify Web UI**: http://your-server:8080

- **Gotify Web UI**: https://gotify.your-domain.com

+    local title="$2"
+    local message="$3"
+    local priority="${4:-default}"
+    local tags="$5"


With set -u, local tags="$5" will throw an “unbound variable” error when the caller provides only 3–4 args (since $5 is not set). Use a default expansion like ${5:-} (and similarly ensure downstream functions handle empty tags) so the script works with the documented optional tags argument.

Suggested change

local tags="$5"

local tags="${5:-}"

Copilot · 2026-04-01T03:05:04Z

+        for tag in "${TAG_ARRAY[@]}"; do
+            tags_json+="\"${tag}\","
+        done
+        tags_json="${tags_json%,}]"


The tag array JSON builder is broken: tags_json="${tags_json%,}]" will not remove the trailing comma and also does not append the closing ], resulting in invalid JSON when tags are provided. Fix the trimming/closing logic (or build the payload with a JSON tool like jq).

Suggested change

tags_json="${tags_json%,}]"

# Remove trailing comma and close JSON array

tags_json="${tags_json%,}"

tags_json+="]"

Copilot · 2026-04-01T03:05:04Z

+    local json_payload="{
+        \"topic\": \"${topic}\",
+        \"title\": \"${title}\",
+        \"message\": \"${message}\",
+        \"priority\": ${priority}"
+
+    if [[ -n "$tags" ]]; then
+        # Convert comma-separated tags to array
+        IFS=',' read -ra TAG_ARRAY <<< "$tags"
+        local tags_json="["
+        for tag in "${TAG_ARRAY[@]}"; do
+            tags_json+="\"${tag}\","
+        done
+        tags_json="${tags_json%,}]"
+        json_payload+=", \"tags\": ${tags_json}"
+    fi
+
+    json_payload+="}"
+


json_payload is assembled via string interpolation without JSON escaping for title/message/topic. If any argument contains quotes, backslashes, or newlines, the request body becomes invalid JSON (or could change the payload structure). Use jq -n --arg ... (or another JSON encoder) to build the payload safely before sending.

Suggested change

local json_payload="{

\"topic\": \"${topic}\",

\"title\": \"${title}\",

\"message\": \"${message}\",

\"priority\": ${priority}"

if [[ -n "$tags" ]]; then

# Convert comma-separated tags to array

IFS=',' read -ra TAG_ARRAY <<< "$tags"

local tags_json="["

for tag in "${TAG_ARRAY[@]}"; do

tags_json+="\"${tag}\","

done

tags_json="${tags_json%,}]"

json_payload+=", \"tags\": ${tags_json}"

fi

json_payload+="}"

local json_payload

json_payload="$(

jq -n \

--arg topic "$topic" \

+      - url: 'https://ntfy.example.com/homelab-alerts'
+        send_resolved: true


The default route receiver is switched to ntfy, but the configured webhook URL is a placeholder (https://ntfy.example.com/...). This will break alert delivery out-of-the-box (Alertmanager will attempt to POST to an invalid endpoint). Keep default as the default receiver and make ntfy an opt-in route, or parameterize the URL via env expansion and document the required Alertmanager flags/env vars.
