Is this a bug or a permission issue?

Hello,
The permissions of the directory where the program sources are located are as follows:

# ls -la
drwxr-xr-x 18 jason jason 4096 May 12 23:05 portal

The compose and Dockerfile files are as follows:

services:
  portal:
    container_name: portal
    build:
      context: /home/jason/portal/
      dockerfile: Dockerfile
    environment:
      - NODE_ENV=development
      - CHOKIDAR_USEPOLLING="true"
      - USER_ID=${USER_ID:-999}
      - GROUP_ID=${GROUP_ID:-995}
    user: "${USER_ID:-999}:${GROUP_ID:-995}"
    volumes:
      - /home/docki/dev/portal-view:/app
      - /app/node_modules
      - /app/.next
    ports:
      - "127.0.0.1:3000:3000"
    deploy:
      resources:
        limits:
          cpus: '4.0'
          memory: 4G

And:

FROM node:23-alpine

# Create app directory with proper permissions
RUN mkdir -p /home/node/app/node_modules && \
    chown -R node:node /home/node/app

WORKDIR /home/node/app

# Copy package files first
COPY --chown=node:node package*.json ./

# Update npm and install dependencies
USER root
RUN npm install -g npm@latest
USER node

RUN npm install --legacy-peer-deps

# Copy app files (excluding problematic paths)
COPY --chown=node:node . .

EXPOSE 3000

CMD ["npm", "run", "dev"]

After running the container I got the following error:

✓ Starting...

}

But inside the container, the file permissions are as follows:

Can’t we say that this problem is unfounded?

Thank you.

Hello,
The problem can be solved by adding RUN chmod -R 777 . to the Dockerfile, but this creates a security issue.
