Where < > width up parameters is required, [] wide up is optional
See docker docker version version number, including client, server, and so dependent on the Go
docker info View System (docker) level information, including the management of images, containers and number
docker search image search in the docker index
docker pull docker registry server from the drop-down image
docker push a push to the image repository or registry
docker push: TAG above, specify the tag
docker inspect or see the underlying image information of container
docker images TODO filter out the intermediate image layers (intermediate image layers what is)
docker images -a list all images
docker ps default display the running container
docker ps -l displays the last created container, including not running
docker ps -a displays all container, including not running
See docker logs container logs, some of which is executing the command output
docker rm delete one or more container
docker rm `docker ps -a -q` remove all container
docker ps -a -q | xargs docker rm above, remove all container
docker rmi delete one or more image
docker start / stop / restart Start / Stop / Restart container
docker start -i to start a container and enter interactive mode
docker attach attach a running container
docker run using the image to create container and execute the appropriate command, and then stop
docker run -i -t / bin / bash to create a container using the image and enter interactive mode, login shell is / bin / bash
docker run -i -t -p container port will be mapped to the host port
docker commit [repo: tag] will solidify a container as a new image, behind the repo: tag optional
docker build
Looking Dockerfile under the path named path configuration files, use this profile to generate a new image
docker build -t repo [: tag] Ibid., you can specify the repo and optional tag
