Docker + NestJS Dev Environment

Docker development environments for NestJS enable instant code changes through hot-reload by mounting your source code into a container running a development server. This Skill generates optimized Dockerfiles, docker-compose.yaml files, and VSCode debugging configuration so you can start developing immediately after running docker-compose up without manual setup.

Yes, remote debugging with VSCode works by exposing the Node.js debugger port inside your container and configuring launch settings. This Skill automatically generates the debugging configuration, allowing you to set breakpoints and inspect variables in your NestJS code running inside Docker.

Docker Compose services for PostgreSQL, MySQL, Redis, and RabbitMQ are defined in a single docker-compose.yaml with health checks, persistent volumes for data retention, and environment variables. This Skill templates these services pre-configured so your NestJS application connects to them immediately without separate installation or configuration steps.

Docker volumes dedicated to node_modules prevent conflicts by keeping dependencies isolated inside the container, separate from your host machine. This Skill configures the volume strategy so npm install runs inside Docker, eliminating mismatches between local and containerized development.

Timezone synchronization ensures logs, timestamps, and scheduled tasks in your NestJS application match your local time zone, preventing debugging confusion. This Skill automatically configures timezone mapping between host and container so times stay consistent across your development workflow.

Development-focused Dockerfiles skip production build steps and enable hot-reload by keeping the dev server running, whereas multi-stage builds optimize for production deployment. This Skill generates a lean development Dockerfile that prioritizes fast iteration and debugging over production image size.
