ENOENT: PS, Spawn PS - Common Issues when Working with Nestjs, Nodejs and Docker

Working Environment:

• VsCode
• Debug Mode
• Nestjs
• Dockerfile
  

What did that happened?

After i ran docker compose up and then i change some file content in my local machine , it will trigger changed in the file system between local and remote host.

Problem: The problem is the docker container image you're using is missing procps

Solution: 

RUN apt-get update && apt-get install -y procps

Example:

FROM node:21-bullseye-slim as development

RUN apt-get update && apt-get install -y procps

WORKDIR /usr/src/app

COPY package.json ./
COPY tsconfig.json tsconfig.json
COPY nest-cli.json nest-cli.json
COPY apps/auth/prisma ./prisma
