Day 20: Docker Cheat Sheet

Docker Images

List all available Docker images on your system:

$docker images

Lists images:

$docker image ls

Download a Docker image from a repository:

$docker pull <image-name>

Push an image to a registry:

$docker push <image-name>

Remove a Docker image from your system:

$docker rmi <image-name>

Build a Docker image from a Dockerfile:

$docker build -t <image-name><path of dockerfile>

Build an image from a Dockerfile located in the current directory:

$docker build .

Create an image from a Dockerfile and tag it:

$docker build -t [name] : [tag] [dockerfile]

Tag an image:

$docker tag [image] : [tag]

Show history for an image:

$docker history [image]

Remove unused images:

$docker image prune

Clears all images that are not being used by containers:

$docker image prune -a

Removes all stopped containers, all networks not used by containers, all dangling images, and all build cache:

$docker system prune

Leaves a swarm:

$docker swarm leave

Removes a swarm:

$docker stack rm stack name

Docker Containers

Create and start a new container from a Docker image

$docker run <image-name>

List all running containers:

$docker ps

Stop a running container:

$docker stop <container-id>

Start a container:

$docker start <container-id>

Restart a running container:

$docker restart <container-id>

Pause process in a running container:

$docker pause <container-id>

Remove a stopped container from your system:

$docker rm <container-id>

Send a KILL signal to stop a container:

$docker kill <container-id>

Execute a command inside a running container:

$docker exec -it <container-id><command>

View the logs of a container:

$docker logs <container-id>

Run a container and remove it after it stops:

$docker run -rm <image>

Run an interactive process:

$docker run -it <image>

Inspects changes to directories and files in the container filesystem:

$docker diff container

Shows all running processes in an existing container:

$docker top container

docker top container:

$docker stats container

Docker Compose

Start containers defined in a Docker Compose file:

$docker-compose up

Stop and remove containers defined in a Docker Compose file:

$docker-compose down

Build or rebuild services defined in a Docker Compose file:

$docker-compose build

View the logs of a specific service defined in a Docker Compose file:

$docker-compose logs <service-name>

Docker Networks

List all available Docker networks:

$docker network ls

Create a new Docker network:

$docker network create <network-name>

Inspect details about a Docker network:

$docker network inspect <network-name>

Remove a Docker network:

$docker network rm <network name>

Docker Volumes

List all available Docker volumes:

$docker volume ls

Create a new Docker volume:

$docker volume create <volume-name>

Inspect details about a Docker volume:

$docker volume inspect <volume-name>

Remove a Docker volume:

$docker volume rm <volume-name>

$docker login

Log out of a Docker registry:

$docker logout

List low-level information on Docker objects:

$docker inspect [object]

Show the version of the local Docker installation:

$docker version

Display information about the system:

$docker info

Remove unused images, containers, and networks:
