Docker Patterns

Docker and Docker Compose best practices for containerized development.

When to Activate

• Setting up Docker Compose for local development
• Designing multi-container architectures
• Troubleshooting container networking or volume issues
• Reviewing Dockerfiles for security and size
• Migrating from local dev to containerized workflow
• Separating dev and production Dockerfile stages to keep the production image minimal and rootless
• Configuring custom bridge networks so database containers are unreachable from the frontend service
