Key Docker Commands - John Kevin Losito's Blog

Compilation of most used Docker commands.

docker build . : Build a Dockerfile and create your own Image based on the file
- -t NAME:TAG : Assign a NAME and a TAG to an image
  - docker build -t myapp:1.0 .
docker run IMAGE_NAME : Create and start a new container based on image IMAGE_NAME
- --name NAME : Assign a NAME to the container. The name can be used for stopping and removing etc.
- -d : Run the container in detached mode – i.e. output printed by the container is not visible, the command prompt/terminal does NOT wait for the container to stop
- -it : Run the container in “interactive” mode – the container/application is then prepared to receive input via the command prompt/terminal. You can stop the container with CTRL + Cwhen using the -it flag.
- --rm : Automatically remove the container when it’s stopped
docker ps : List all running containers.
- -a : List all containers including stopped ones.
docker images : List all stored images
docker rm CONTAINER : Remove a container with the name CONTAINER
docker rmi IMAGE : Remove an IMAGE
docker container prune : Remove all stopped containers
docker image prune : Remove all untagged images
- -a : Remove all locally stored images
docker push IMAGE : Push an image to DockerHub (or another registry) – the image name/tag must include the repository name/ URL
- docker push johnkevinlosito/myapp
docker pull IMAGE : Pull (download) an image from DockerHub (or another registry) – this is done automatically if you just docker run IMAGEand the image wasn’t pulled before
docker run -v /path/in/container IMAGE : Create an anonymous volume inside the container
docker run -v some-name:/path/in/container IMAGE : Create a named volume (some-name) inside a Container
docker run -v /path/on/your/host/machine:path/in/container IMAGE : Create a BindMount and connect a local path on your host machine to some path in the Container
docker volume ls : List all currently active/stored volumes (by all Containers)
docker volume rm VOL_NAME : Remove a volume by its name
docker volume prune : Remove all unused volumes (i.e. not connected to a currently running or stopped container)
docker network create NETWORK_NAME : Create a container network
docker run -network NETWORK_NAME --name my-container my-image : Run a container on the network (network must be created first)
docker-compose up: Start all containers/services mentioned in the Docker Compose file
- -d: Start in detached mode
- --build : Force Docker Compose to rebuild all images
docker-compose down : Stop and remove all containers/services
- -v : Remove all Volumes used for the Containers – otherwise, they stay around, even if the Containers are removed
