Summary

Add Woodpecker CI pipeline, multi-stage Dockerfile, and Kubernetes manifests to enable automated container builds and deployment via Harbor registry
Standardize container port to 8000 and migrate from old direct-pip-install Docker pattern to multi-stage build with Forgejo PyPI index
Add ruff linting configuration and format fixes

Changes

Dockerfile: Multi-stage build (python:3.12-slim), PIP_INDEX_URL build arg for Forgejo PyPI, BUILD_SHA label, port 8000, python server.py entrypoint
.woodpecker.yml: Lint step (ruff==0.15.2 check + format), build-and-push step (Kaniko to Harbor linkedin-scheduler-remote/server), ArgoCD path exclusion
k8s/deployment.yaml: Deployment (harbor image, imagePullSecrets harbor-creds, env from linkedin-mcp-secrets, PVC at /app/data, resource limits, health probes), Service (port 8000), PVC (100Mi local-path)
.dockerignore: Exclude .env, .venv, .git, k8s, systemd, build artifacts
pyproject.toml: Add [tool.ruff] config (py312, line-length 120, E/F/I/W rules), add [project.optional-dependencies] dev group
server.py: Add ruff: noqa: I001 directive for intentional import ordering (monkey-patch pattern)
client_patch.py: Ruff format fixes (line length normalization)

Test Plan

ruff check . passes
ruff format --check . passes
Woodpecker CI lint step passes on PR
Container builds successfully with Kaniko on main merge
K8s deployment applies cleanly (no namespace hardcoded, secrets match)

Review Checklist

No secrets committed
No unnecessary file changes
Commit messages are descriptive
Port standardized to 8000
Secret name updated to linkedin-mcp-secrets
PVC name updated to linkedin-mcp-data
imagePullSecrets set to harbor-creds
Resource limits included

fix: rename lint step to test, add pip install .[dev] and pytest

ci/woodpecker/pr/woodpecker Pipeline was successful

Details

3237ef5ebd

Match the task spec by combining lint and test into a single step
named "test" that installs dev dependencies, runs ruff, and runs
pytest with soft-fail (|| true) for when tests/ does not yet exist.

Review-fix round 1:

Self-review found the .woodpecker.yml was missing the pip install .[dev] and python -m pytest tests/ || true commands from the task spec. The lint-only step has been renamed to test and expanded to include dev dependency installation and a soft-fail pytest invocation, matching the standard pattern.

Pushed fix in commit 3237ef5.

PR #2 Review

BLOCKERS

B1. ${CI_COMMIT_SHA} uses curly braces in .woodpecker.yml (2 occurrences)

tags: ${CI_COMMIT_SHA}

- BUILD_SHA=${CI_COMMIT_SHA}

Per deployment-lessons SOP: "Use $CI_COMMIT_SHA (without curly braces) in plugin settings. Curly braces (${CI_COMMIT_SHA}) conflict with Woodpecker's compiler." Both the tags: field and the BUILD_SHA build arg must use $CI_COMMIT_SHA.

B2. Test step uses || true, silently swallowing failures

- python -m pytest tests/ || true

This means CI will never fail on broken tests. Per the plan's Phase 2 decisions: "Tests that silently skip when creds are missing are lazy and give false confidence. If credentials are missing, tests should fail." The || true contradicts this philosophy. If tests require runtime secrets, those secrets should be added to Woodpecker and the step should fail honestly when they are missing.

B3. Missing k8s/kustomization.yaml

The plan Phase 3 explicitly requires: "Add k8s/ directory to each repo: kustomization.yaml, deployment.yaml, servicemonitor.yaml." The kustomization.yaml is missing. ArgoCD can work in directory mode, but the plan mandates it. At minimum it should list deployment.yaml as a resource.

B4. Missing k8s/servicemonitor.yaml

Same as B3 -- the plan Phase 3 requires a servicemonitor.yaml for Prometheus scraping. Even a basic ServiceMonitor targeting port 8000 on /health or /metrics is needed.

NITS

N1. Ruff target-version is py312, task checklist says py310

The pyproject.toml sets target-version = "py312" which is consistent with the python:3.12-slim Dockerfile base image. If py312 is intentional (it appears to be), this is fine. Just flagging the discrepancy with the task description.

N2. pyproject.toml URLs still point to GitHub

Repository = "https://github.com/ldraney/linkedin-scheduler-remote"
Issues = "https://github.com/ldraney/linkedin-scheduler-remote/issues"

These should be updated to Forgejo URLs since the repo has been migrated. Non-blocking but worth fixing.

N3. .dockerignore does not exclude tests/

Tests are not needed in the container image. Adding tests/ to .dockerignore would reduce image size slightly. Non-blocking.

SOP COMPLIANCE

PR #2 Review

BLOCKERS

1. Service port not named -- ServiceMonitor will fail to scrape metrics

In k8s/deployment.yaml, the Service defines its port without a name:

spec:
  ports:
    - port: 8000
      targetPort: 8000

But k8s/servicemonitor.yaml references port: http:

endpoints:
  - port: http
    path: /metrics
    interval: 30s

The ServiceMonitor matches endpoints by port name, not by number. Since the Service port has no name, the ServiceMonitor will find zero endpoints and no metrics will be scraped.

Fix: Add name: http to the Service port definition:

spec:
  ports:
    - name: http
      port: 8000
      targetPort: 8000

NITS

None.

Dockerfile runs as root. No USER directive -- the container runs as root. Best practice is to create a non-root user (RUN adduser --system appuser && USER appuser).
