Essential Docker Commands: How to Efficiently Manage All Your Containers

Posted by

Docker is a sophisticated containerization solution that enables developers to bundle programs and their dependencies into separate environments. Maintaining a healthy and scalable system requires effective Docker container management. This article covers the core commands for controlling all Docker containers, such as listing, starting, stopping, deleting, and inspecting containers.

To manage all Docker containers, several commands can be useful. Here is a comprehensive list of commands that you might need for managing all containers in Docker:

1. List All Containers

To list all running and stopped containers:

bashCopy codedocker ps -a

2. Stop All Running Containers

To stop all running containers:

bashCopy codedocker stop $(docker ps -q)

3. Start All Stopped Containers

To start all stopped containers:

bashCopy codedocker start $(docker ps -aq -f "status=exited")

4. Restart All Running Containers

To restart all running containers:

bashCopy codedocker restart $(docker ps -q)

5. Remove All Stopped Containers

To remove all stopped containers:

bashCopy codedocker rm $(docker ps -aq -f "status=exited")

6. Remove All Containers (Running and Stopped)

To remove all containers, whether they are running or stopped:

bashCopy codedocker rm -f $(docker ps -aq)

7. Remove All Containers and Their Volumes

To remove all containers and their volumes:

bashCopy codedocker rm -vf $(docker ps -aq)

8. Kill All Running Containers

To kill all running containers:

bashCopy codedocker kill $(docker ps -q)

9. Attach to All Running Containers

To attach to all running containers (useful for logging purposes):

bashCopy codedocker attach $(docker ps -q)

10. Export All Containers

To export all containers to tar files:

bashCopy codefor container in $(docker ps -aq); do
  docker export $container > ${container}.tar;
done

11. Import All Containers

To import all containers from tar files:

bashCopy codefor file in *.tar; do
  cat $file | docker import -;
done

12. Inspect All Containers

To inspect all containers and get detailed information:

bashCopy codefor container in $(docker ps -aq); do
  docker inspect $container;
done

13. Show Logs for All Running Containers

To show logs for all running containers:

bashCopy codefor container in $(docker ps -q); do
  docker logs $container;
done

14. Prune All Containers

To remove all stopped containers, unused networks, and dangling images:
