Docker Operations

To start Docker containers with docker-compose, run docker-compose up -d to bring up the backend, frontend, and MongoDB services in detached mode. Stop the containers using docker-compose down to cleanly tear down the environment.

Docker container health checks fail when the backend or frontend service crashes on startup. Inspect the logs with docker-compose logs to identify the error, then verify your docker-compose.yml network and volume configurations are correct.

Yes, you need both Docker and Docker Compose installed locally to manage containers for a web app. You also need a docker-compose.yml file in your project root to define the backend, frontend, and database services.

The best way to troubleshoot containerized services is to inspect logs, check health status, and review resource usage with Docker CLI. This diagnostic approach helps resolve issues across backend, frontend, and MongoDB containers.

Rebuild Docker images using docker-compose build to apply code changes, then prune unused resources with docker system prune to clear stale containers and networks. This ensures reliable deployments and resolves configuration conflicts.

Yes, docker-compose orchestrates MongoDB alongside backend and frontend containers by defining them as services in the docker-compose.yml file. This provides a consistent, production-like deployment environment for local development.
