Editing Docker (section)

===Docker===

 // general options
 -H=<REMOTE_DOCKER_ENGINE>:<PORT> // e.g. docker -H=<IP>:<PORT> run nginx

 docker build [--tag <IMAGE_NAME>] . // uses the file 'Dockerfile' in the actual directory and creates an image named <IMAGE_NAME>

 docker container ls

 docker exec // e.g. docker exec -it <CONTAINER_ID> bash

 docker image (ls | prune | remove <IMAGE_NAME>)

 docker images // lists all images

 docker inspect <CONTAINER_NAME>

 docker logs <CONTAINER_NAME> // shows log of the container

 docker network create <NETWORK_NAME>
 docker network ls
 docker network inspect bridge // show details for the default network 'bridge'

 docker pull <IMAGE> // e.g. docker pull mysql/mysql-server:latest

 docker ps [<OPTIONS>] // lists all running containers
 // -a all e.g. all containers in exited state

 docker restart <CONTAINER_ID> // eg. docker restart d4

 docker rm <CONTAINER_NAME>

 docker rmi <IMAGE_NAME> // deletes an image

 docker run [<[https://docs.docker.com/engine/reference/commandline/run/ RUN_OPTIONS]>]  <IMAGE_NAME>:<TAG> [<COMMANDS>] [<ARGS>] // runs an image
 // RUN_OPTIONS are:
 // --cpus=<NUMBER>
 // -d detach, run in background
 // -e <ENV_VARIABLE_NAME>=<VALUE>
 // --entrypoint <OVERWRITTEN_ENTRYPOINT>
 // -i use stdin
 // --link <CONTAINER_REF>:<CONTAINER_NAME>
 // --memory=<AMOUNT>
 // --mount type=bind,source=<HOST_DIR>,target=<CONTAINER_DIR> // moderne volume mounting
 // --name <NAME>
 // --network=<NETWORK_NAME>
 // -p <HOST_PORT_NUMBER>:<CONTAINER_PORT_NUMBER>
 // -rm // to remove the container after it has executed
 // -t attach terminal
 // -v <VOLUME_NAME>:<CONTAINER_DIR>, <VOLUME_NAME> is located in /var/lib/docker/volumes/... of the host file system, this is called volume mounting
 // -v <HOST_DIR>:<CONTAINER_DIR>, this is called bind mounting
 // <TAG> can be a version number, default is 'latest'
 // <COMMANDS> overwrite the CMD of the docker file
 //
 // e.g. docker run --name=TestMySQL -d mysql/mysql-server:latest


 docker start
 docker stop <CONTAINER_NAME>

 docker system prune // removes all stopped container, unused container, dangling images, dangling build cache

 docker volume (create | ls | rm | prune | …) // /var/lib/docker/volumes/<VOLUME_NAME>
