Docker Cheatsheet

#cloud #docker #kubernetes #discuss

I often find myself looking up commands or forgetting what I did for a simple task. Thought it would be a good opportunity to compile all the Docker commands I am using on a regular basis for developing applications with Docker. Hoping to crowdsource this, so let me know in the comments below!

DOCKER MACHINE

List all Docker engines:

docker-machine ls
Enter fullscreen mode Exit fullscreen mode

Create a Docker engine:

docker-machine create --driver virtualbox default
Enter fullscreen mode Exit fullscreen mode

Set environment variables for Docker engine:

docker-machine env default
eval $(docker-machine env default)
Enter fullscreen mode Exit fullscreen mode

Start a Docker engine:

docker-machine start default
Enter fullscreen mode Exit fullscreen mode

Stop a Docker engine:

docker-machine stop default
Enter fullscreen mode Exit fullscreen mode

Retrieve IP address for running Docker engine:

docker-machine ip default
Enter fullscreen mode Exit fullscreen mode

DOCKER IMAGES

List Docker images:

docker images
Enter fullscreen mode Exit fullscreen mode

Remove Docker image:

docker rmi <image_id>
docker image rm <image_id>
Enter fullscreen mode Exit fullscreen mode

Create Docker image (requirement: Dockerfile):

docker build -t <dockerhub_username>/<custom_docker_image_name> .
Enter fullscreen mode Exit fullscreen mode

DOCKER CONTAINERS

List Docker containers:

docker ps
docker container ls -a
Enter fullscreen mode Exit fullscreen mode

Stop and remove Docker container:

docker stop <container_id>
docker rm <container_id>
Enter fullscreen mode Exit fullscreen mode

Remove all stopped Docker containers:

docker container prune
Enter fullscreen mode Exit fullscreen mode

Delete all stopped containers:

docker rm $(docker ps -a -q)
Enter fullscreen mode Exit fullscreen mode

Create Docker container (requirement: Docker image):

docker run --name <custom_container_name> -p <new_port>:<defined_port> -d <dockerhub_username>/<custom_docker_image_name>
Enter fullscreen mode Exit fullscreen mode

DOCKER COMPOSE

If development, build, run and keep running (e.g. service_id equals dev):

docker-compose build <service_id>
docker-compose up <service_id>
Enter fullscreen mode Exit fullscreen mode

If testing, build and run once (e.g. service_id equals test):

docker-compose build <service_id>
docker-compose run --rm <service_id>
Enter fullscreen mode Exit fullscreen mode

DOCKER SYSTEM

Remove all unused containers, networks, images (both dangling and unreferenced), volumes and any resource created. Note: Do not apply this command for resources in production. Recommended for use in dev/test environments.

docker system prune -a
Enter fullscreen mode Exit fullscreen mode

Great Cheatsheet !!
I would add:
docker rm $(docker ps -a -q)
to delete all stopped containers

It's wrong this command since it will remove all containers (running and stopped containers)!
docker ps -a -q will show you all containers into short syntax and docker rm will remove them!
The right syntax should be docker rm $(docker ps --filter status=exited -q) to remove all stopped containers

No you have to use -f (force) to remove also running containers

it's really nice cheatsheet.
I would like to add :
docker system prune -a
to delete all the resources which has been created by user.
Note: Do not apply this command in production like environment. it is just for practice purpose.
