Clean up Docker images and volumes by running targeted prune commands and reviewing Docker system reports first. This reclaims disk space by removing dangling images and orphaned storage layers while validating active containers to prevent unintended data loss during deletion.

Docker Compose stacks fail to start due to port conflicts, misconfigured environment variables, or unhealthy dependencies. Diagnose these failures by inspecting per-service logs, validating the resolved configuration, and checking container health and process visibility.

The best way to restart a Docker Compose stack without losing data is running `docker compose down` followed by `docker compose up -d`. This safely tears down and rebuilds the multi-service app while preserving persistent volume data.

Debug a stuck Docker container using the CLI by accessing an exec shell, reviewing container logs, and running `docker inspect` to check status and health. Use `docker stats` to monitor resource consumption and identify operational bottlenecks.

Yes, you can manage Docker container lifecycle operations via CLI by running start, stop, restart, remove, and pause/unpause commands. Each action requires validation through `docker ps` and logs to confirm the resulting container status and health.

Avoid pruning Docker networks and volumes when containers are actively running or when storage layers contain critical unpersisted data. Always inspect active processes and validate system reports before executing cleanup to prevent unintended data loss.
