Frequently asked questions

How can I remove unused Docker resources?

Use the `docker system prune` command to remove unused resources. This command will remove stopped containers, unused networks, dangling images, and build caches.

Does `prune` remove unused volumes or networks?

`docker system prune` removes unused containers, networks, images, and build caches. To specifically remove unused volumes, use the `docker volume prune` command; to remove unused networks, use `docker network prune`. Be cautious as these commands permanently delete data.

How can I check disk usage before cleaning my Docker environment?

Use the `docker system df` command to view disk space utilization by Docker images and containers. This allows you to identify which resources are consuming the most storage.

What is the difference between `ENTRYPOINT` and `CMD`?

`ENTRYPOINT` defines the main executable for a container, while `CMD` provides default arguments to that executable. The combination of both determines the final command executed when the container starts.
