Docker Hub
Docker Syntax | Description |
---|---|
docker search search_word | Search docker hub for images. |
docker pull user/image | Downloads an image from docker hub. |
docker login | Authenticate to docker hub |
docker push user/image | Uploads an image to docker hub. |
Clean Up
Volumes
docker volume prune
Remove all volumes not used by at least one container
Images
Remove all dangling (not tagged and is not associated with a container) images:
docker image prune
Remove all images which are not used by existing containers
docker image prune -a
Containers
Stop all running containers
docker stop $(docker ps -a -q)
Delete stopped containers
docker container prune
Clean All
Cleans up dangling images, containers, volumes, and networks (ie, not associated with a container)
docker system prune
Additionally, remove any stopped containers and all unused images (not just dangling images)
docker system prune -a
Docker Networking
Creating Networks
docker network create -d overlay MyOverlayNetwork docker network create -d bridge MyBridgeNetwork docker network create -d overlay \ --subnet=192.168.0.0/16 \ --subnet=192.170.0.0/16 \ --gateway=192.168.0.100 \ --gateway=192.170.0.100 \ --ip-range=192.168.1.0/24 \ --aux-address="my-router=192.168.1.5" \ --aux-address="my-switch=192.168.1.6" \ --aux-address="my-printer=192.170.1.5" \ --aux-address="my-nas=192.170.1.6" \ MyOverlayNetwork
Docker Images
Building Images
$ docker build . $ docker build github.com/creack/docker-firefox $ docker build - < Dockerfile $ docker build - < context.tar.gz $ docker build -t eon/my-nginx . $ docker build -f myOtherDockerfile . $ curl example.com/remote/Dockerfile | docker build -f - .
Docker Containers
Manipulating
Renaming a Container
docker rename my-nginx my-nginx
Removing a Container
docker rm my-nginx
Updating a Container
docker update --cpu-shares 512 -m 300M my-nginx
Creating
docker create [options] IMAGE -a, --attach # attach stdout/err -i, --interactive # attach stdin (interactive) -t, --tty # pseudo-tty --name NAME # name your image -p, --publish 5000:5000 # port map (host:container) --expose 5432 # expose a port to containers -P, --publish-all # publish all ports --link container:alias # linking -v, --volume `pwd`:/app # mount (absolute paths needed) -e, --env NAME=hello # env vars
#Example
$ docker create --name my\_redis --expose 6379 redis:3.0.2

Getting Started
Create and run a container in background
$ docker run -d -p 80:80 docker/getting-started
-d
- Run the container in detached mode-p 80:80
- Map port 80 to port 80 in the containerdocker/getting-started
- The image to use Create and run a container in foreground
$ docker run -it -p 8001:8080 --name my-nginx nginx
-it
- Interactive bash mode-p 8001:8080
- Map port 8001 to port 8080 in the container--name my-nginx
- Specify a namenginx
- The image to use
