@Lajithaalagarbabu Lajithaalagarbabu commented Jul 23, 2025

his Pull Request introduces the necessary Docker configuration files to enable containerized deployment of our application(s).

Key Changes:

docker-compose.yml:** Added to the root directory to define the multi-service application stack. This file orchestrates our:
* frontend service (built from apps/my-frontend/Dockerfile)
* backend service (built from apps/my-backend/Dockerfile)
* mongo database service (pre-built image for persistence)
*(Adjust service names and Dockerfile paths as per your actual implementation)

Dockerfiles: Individual Dockerfiles have been added within their respective application directories (e.g., apps/my-frontend/Dockerfile, apps/my-backend/Dockerfile) to define how each service's Docker image should be built.

Purpose & Benefits:

Containerization: Allows our application components to run in isolated, portable Docker containers.
Simplified Deployment: Enables easy local testing using Docker Compose (docker-compose up --build) and streamlined deployment to environments like Portainer.
Consistent Environments: Ensures consistent development and production environments, reducing "it works on my machine" issues.

Next Steps (after merge):

Once this PR is merged into the develop branch, the application can be deployed as a stack in Portainer using the "Repository" build method, pointing to this docker-compose.yml file.

Please review the changes and let me know if any adjustments are needed.

Walkthrough

A new Dockerfile has been added to the apps/page directory. This file sets up a Node.js 20 Alpine-based container for building and running the frontend app, handling dependency installation, build steps, and exposing port 3000.

Poem

In a Docker burrow, neat and small,
A Node app waits to serve us all.
With pnpm snacks and port three-oh-oh,
The page hops live, ready to go!

13-15: Prefer corepack over globally installing pnpm

Node 20 ships with corepack; enabling it keeps the image slimmer and pins the pnpm version.

-RUN npm install -g pnpm
+RUN corepack enable && corepack prepare pnpm@8.10.0 --activate

6-11: Leverage build-cache & reduce context size

  1. Copy only the files needed for dependency resolution before pnpm install; moving COPY . . later tightens the cache.
  2. Add a .dockerignore to avoid sending node_modules, dist, etc., which bloats the context.
node_modules
dist
.git

17-24: Consider a multi-stage build to ship a slimmer runtime image

Right now the final image contains dev dependencies and build toolchain.
Typical pattern:

# ---- build stage ----
FROM node:20-alpine AS build
WORKDIR /app
# …copy lockfiles & install deps
RUN pnpm run build

# ---- runtime stage ----
FROM node:20-alpine
WORKDIR /app
COPY --from=build /app/apps/my-frontend/.output ./ # or dist path
EXPOSE 3000
CMD ["node", "server.js"]

This can cut image size by >50 % and reduce attack surface.

⚠️ Potential issue

Inline comment after JSON array breaks the Dockerfile syntax

Docker does not allow trailing characters after the JSON‐array form of CMD.
This line will fail to build (hadolint DL1000 confirms).

-CMD ["pnpm", "start"] # Or "node dist/index.js", etc.
+# Optional: choose one of the two commands below
+# CMD ["node", "dist/index.js"]
+CMD ["pnpm", "start"]
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🤖 Prompt for AI Agents
In apps/page/Dockerfile at line 24, remove the inline comment after the JSON
array in the CMD instruction because Dockerfile syntax does not allow trailing
characters after the JSON array form. Place any comments on separate lines above
the CMD instruction to fix the build error.
