The CMD ["bun", "run", "start"] command on line 35 will fail because it's executed from /app, but the application files are in /app/apps/frontend/. The start command needs to run from the correct directory.

Suggested fix: Update the command to specify the working directory:

WORKDIR /app/apps/frontend
CMD ["bun", "run", "start"]

Or update the CMD:

CMD ["bun", "run", "start", "--cwd", "./apps/frontend"]

The Railway deployment step is missing critical information for a successful deployment. The railwayapp/cli-action@v1 requires additional parameters such as:

  • service: The service name to deploy
  • environment: The environment to deploy to (e.g., production, staging)

Without these parameters, the deployment may fail or deploy to an unintended target.

[nitpick] The Docker image is tagged only as latest (line 57), which makes it difficult to track which version is deployed and can cause issues with rollbacks. Consider implementing a versioning strategy using commit SHA or semantic versioning.

Suggested improvement:

- name: Build and push
  uses: docker/build-push-action@v4
  with:
    context: apps/backend
    push: true
    tags: |
      ghcr.io/${{ github.repository }}/backend:latest
      ghcr.io/${{ github.repository }}/backend:${{ github.sha }}

This allows you to track deployments and roll back to specific versions if needed.

The bun run build command on line 15 will fail because it's executed from /app, but the Next.js project is located in /app/apps/frontend/. The build command needs to run from the correct directory.

Suggested fix: Add --cwd flag or change working directory:

RUN bun run build --cwd ./apps/frontend

Or set the working directory:

WORKDIR /app/apps/frontend

The Trivy security scan on line 59 will attempt to scan an image that may not be publicly accessible from the GitHub Actions runner. Additionally, using @master for the action version is not a best practice as it can lead to unexpected breaking changes.

The bun install command on line 9 will fail because it runs from /app directory, but the package.json and bun.lock are copied to /app/apps/frontend/. The install command needs to specify the correct working directory or be run from the subdirectory.

Or change to the directory first:

The Docker build context is set to apps/frontend, but the Dockerfile copies files from apps/frontend/ within the container. This creates a mismatch where the Dockerfile expects to be run from the repository root, but the workflow sets the context to the apps/frontend directory.

This will cause the build to fail because paths like COPY apps/frontend/package.json won't work when the context is already apps/frontend.

Suggested fix: Either change the context to . (repository root):

context: .
file: apps/frontend/Dockerfile

Or update the Dockerfile to work with apps/frontend as the context by removing the apps/frontend/ prefix from COPY commands.

Suggested change
context: apps/frontend
context: .

The Trivy security scan on line 63 will attempt to scan an image that may not be publicly accessible from the GitHub Actions runner, since it was just pushed to GHCR. The scan should either:

  1. Pull the image first after authenticating, or
  2. Scan the local image before pushing, or
  3. Include proper authentication for pulling from GHCR

Additionally, using @master for the action version is not a best practice as it can lead to unexpected breaking changes.

[nitpick] The workflow uses push to main branch as a trigger (lines 5-7), which means every push to main will trigger build, push, and deploy. This could lead to unnecessary deployments if multiple commits are pushed quickly or if the deploy should only happen on releases.

Consider adding conditions to prevent deployment on every push:

on:
  push:
    branches:
      - main
    tags:
      - 'v*'  # Deploy only on version tags
  pull_request:
    branches:
      - main

jobs:
  # ... test and build jobs ...
  
  deploy:
    runs-on: ubuntu-latest
    needs: build_and_push
    if: github.event_name == 'push' && github.ref == 'refs/heads/main'  # Only deploy on push to main, not PRs

Hey! Thanks for the PR. I found a few issues that need fixing:

Main Issues:

  1. Wrong frontend path - The workflows and Dockerfile reference apps/frontend but the actual frontend is in apps/frontend-new. This will cause the workflows to fail.

  2. Duplicate workflows - We already have CI/CD workflows in .github/workflows/ci-cd.yml that do similar things. This might cause conflicts or duplicate runs.

  3. Missing type-check script - The frontend workflow runs bun run type-check but that script doesn't exist in apps/frontend-new/package.json. The existing workflow uses bunx tsc --noEmit instead.

  4. Backend should use uv - The backend workflow uses pip but we prefer uv for Python (see existing ci-cd.yml).

  5. Outdated action versions - Using actions/checkout@v3 and setup-python@v4 while existing workflows use v4/v5.

  6. Missing permissions - The workflows don't set proper permissions which might cause issues.

  7. Dockerfile path issue - The frontend Dockerfile references apps/frontend which doesn't exist.

Suggestions:

  • Either update the paths to use apps/frontend-new or consolidate with the existing workflows
  • Use uv for backend instead of pip
  • Add proper permissions blocks
  • Update action versions to match existing workflows
  • Fill out the PR description template (it's currently empty)

The CI/CD pipeline implementation is well-structured and covers the necessary stages for build, test, and deployment. I appreciate the use of environment variables and the separation of concerns within the workflow files.
However, it would be beneficial to include more granular error handling, especially for deployment steps, to ensure easier debugging in case of failure. Please also consider adding caching for dependencies in the build stage to improve performance.
Lastly, a brief README update summarizing the workflow changes would help future contributors quickly understand the CI/CD process.
