Common Docker Commands¶
This is a short summary of the most commonly used Docker commands. If you're new to Docker, or even experienced Docker, it can be helpful to have a quick reference to the most commonly used Docker commands for managing the Docker environment.
Show all Containers Including Running and Stopped¶
docker ps -a
Show Docker Container Logs¶
docker logs <container_id>
Get A Container Shell¶
docker exec -it <container_id> /bin/bash
or
docker exec -it <container_id> /bin/sh
depending on the shells available on the Docker image.
Stoping Containers¶
docker stop <container_id>
foce stop with kill
docker kill <container_id>
Removing Containers¶
docker rm <container_id>
force remove
docker rm -f <container_id>
Find Container IP Address¶
docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' <container name/id>
Copy Files into Docker Container¶
docker cp <local file> <container name/id>:<remote file>
Copy Files from Docker Container¶
docker cp <container name/id>:<remote file> <local file>
Purging¶
Purging All Unused or Dangling Images, Containers, Volumes, and Networks Docker provides a single command that will clean up any resources — images, containers, volumes, and networks — that are dangling (not associated with a container):
docker system prune
To additionally remove any stopped containers and all unused images (not just dangling images), add the -a flag to the command:
docker system prune -a
Monitor System Resource Utilization for Running Containers¶
To check the CPU, memory, and network I/O usage of a single container, you can use:
docker stats <container>
For all containers listed by ID:
docker stats $(docker ps -q)
For all containers listed by name:
docker stats $(docker ps --format '{{.Names}}')
For all containers listed by image:
docker ps -a -f ancestor=ubuntu
Remove all untagged images:
docker rmi $(docker images | grep “^” | awk '{split($0,a," "); print a[3]}')
Remove container by a regular expression:
docker ps -a | grep wildfly | awk '{print $1}' | xargs docker rm -f
Remove all exited containers:
docker rm -f $(docker ps -a | grep Exit | awk '{ print $1 }')
