CLI Cheat Sheet

Create

• Build an Image from a Dockerfile docker build -t <image_name> .
• Build an Image from a Dockerfile without the cache docker build -t <image_name> . –no-cache
• Pull an image from a Docker Hub docker pull <image_name>

  Start Stop

• Start the docker daemon docker -d
• Create and run a container from an image, with a custom name: docker run --name <container_name> <image_name>
• Run a container with and publish a container’s port(s) to the host. docker run -p <host_port>:<container_port> <image_name>
• Run a container in the background docker run -d <image_name>
• Run and open Shell docker run -it <image_name>
• Open a shell inside a running container docker exec -it <container_name> sh
• Run a docker file docker run <image_name>
• Start or stop an existing container docker start|stop <container_name> (or <container-id>)

  Remove

• Remove a stopped container docker rm <container_name>
• Delete an Image docker rmi <image_name>
• Remove all unused images docker image prune
• Delete an Image by force docker rmi -f <image_name>

  List

• List local images docker images
• List all docker containers (running and stopped) docker ps --all
• Fetch and follow the logs of a container: docker logs -f <container_name>
• To inspect a running container docker inspect <container_name> (or <container_id>)
• Inspect running container to show IP PORTS docker inspect -f 'IP: , Ports: ' <container_id>
• Show open ports in docker docker port <container_id>
• To list currently running containers docker ps

  File Transfer

• Host to docker docker cp /path/to/local/file <container_id>:/path/inside/container
• Docker to host docker cp <container_id>:/path/inside/container/file /path/to/local/folder

  Docker Hub

• Login into Docker docker login -u <username>
• Publish an image to Docker Hub docker push <username>/<image_name>
• Search Hub for an image docker search <image_name>

  Docker persistence

• Command to make docker persistent docker update --restart=always <CONTAINER_ID>
• list all killed containers docker ps -all to copy container id
• restart that container docker start <CONTAINER_ID>
• attatch that container docker attach <CONTAINER_ID>
• get shell docker exec -it <CONTAINER_ID> /bin/zsh
• For persitent docker volume, follow https://docs.docker.com/get-started/docker-concepts/running-containers/persisting-container-data/

  Others

• View resource usage stats docker container stats
• Get help with Docker. Can also use –help on all subcommands docker --help
• Display system-wide information docker info
