❌ Docker & containerization: Optimize Dockerfiles with multi-stage builds and avoid running containers as root for security.

These are the improvements you should make:

• Use multi-stage builds in Dockerfile to optimize image size and security.
• Avoid running as root in Dockerfile: Add a non-root user and switch to it with the USER instruction.

Use multi-stage builds in Dockerfile to optimize image size and security.

You are currently using a single-stage build in your Dockerfile. Implementing multi-stage builds will help reduce the final image size and improve security by only including necessary files in the runtime image. Here’s how you can modify your Dockerfile:

# Builder stage
FROM node:14-alpine AS builder
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .

# Runtime stage
FROM node:14-alpine
WORKDIR /usr/src/app
COPY --from=builder /usr/src/app/dist ./dist
ENV PORT 8080
EXPOSE 8080
CMD ["npm", "start", "--no-update-notifier"]

Avoid running as root in Dockerfile: Add a non-root user and switch to it with the USER instruction.

Running containers as the root user poses security risks. You should create a non-root user and switch to it before running your application. Here’s how to implement this in your Dockerfile:

+ RUN addgroup -S appgroup && adduser -S appuser -G appgroup
+ USER appuser

This ensures that your application runs with limited privileges, enhancing security.
