Remove All Containers

Forcefully remove all containers (running or stopped).

docker rm -f $(docker ps -aq)

View Container Logs

Stream logs from a specific container to your terminal.

docker logs -f <container_id_or_name>

Execute Command in Running Container

Open an interactive shell inside a running container.

docker exec -it <container_id_or_name> /bin/bash
# Or for alpine-based images
docker exec -it <container_id_or_name> /bin/sh

Inspect Container Details

Get detailed JSON information about a container's configuration.

docker inspect <container_id_or_name>

Copy Files to/from Container

# From host to container
docker cp ./local-file.txt <container_id>:/path/in/container

# From container to host
docker cp <container_id>:/path/in/container ./local-file.txt

Image Management

Remove All Unused Images

Free up disk space by removing dangling images.

docker image prune -a

Check Disk Usage

See how much space Docker is using for images, containers, and volumes.

docker system df

Deep Clean (System Prune)
