Mapping ntfy to host port 80 will conflict with the existing Traefik service in stacks/base (also binds 80/443), and it bypasses the repo’s standard reverse-proxy approach. Consider attaching ntfy to the existing external proxy network and exposing it via Traefik labels instead of ports: 80:80.

Healthcheck test is declared as a JSON-array CMD, but includes shell syntax (|| exit 1) which will be passed as an argument to wget and makes the healthcheck invalid. Use CMD-SHELL with a single string, or remove the || exit 1 and rely on wget’s exit code.

Same issue as ntfy: the healthcheck uses test: ["CMD", ... "http://..." || exit 1], which is not valid for CMD array form. Switch to CMD-SHELL or drop the shell operators.

There was a problem hiding this comment.
GOTIFY_DEFAULTUSER_PASS defaults to a hard-coded password (ChangeMe123!). This creates an insecure default and violates the repo’s pattern of requiring secrets to be provided via .env (see .env.example where GOTIFY_PASSWORD is marked REQUIRED). Make GOTIFY_PASSWORD mandatory (no default) and fail fast / document setup.

This stack introduces an external network named homelab, but the rest of the repository standardizes on the external proxy network (created in stacks/base). Using a new network name will break cross-stack connectivity expectations and the documented bootstrap steps; consider reusing proxy instead of introducing homelab.

The script always sends an Authorization: Bearer ... header even when NTFY_TOKEN is unset/empty, and NTFY_TOKEN isn’t documented in the help text. Only include the header when a token is set, and document the variable (or support basic auth) to avoid confusing auth failures.

Same as ntfy: Gotify requests use curl -s which won’t fail on HTTP 4xx/5xx. This can report success when the token is invalid or the server returns an error. Use -f and handle non-2xx responses as failures.

After sanitizing the topic, the script doesn’t validate that it’s still non-empty. Inputs like --- or only invalid characters will produce an empty topic and result in a broken publish request. Add a post-sanitization check and fail with a clear error.

There was a problem hiding this comment.
The README suggests GOTIFY_PASSWORD is optional and provides ChangeMe123! as an example/default, but this encourages an insecure deployment. Prefer marking it REQUIRED (matching .env.example) and avoid documenting weak/default passwords.
| # Gotify password (optional) | |
| GOTIFY_PASSWORD=ChangeMe123! | |
| # Gotify admin password (required - set a strong, unique value) | |

The Quick Start instructs creating a homelab network, but the rest of the repo bootstraps an external proxy network (stacks/base). Consider updating the docs (and compose) to reuse proxy to avoid deployment confusion and ensure services are reachable via the existing Traefik setup.
