+ `docker ps`
  —  Lists running containers. Some useful flags include: -a / -all for all containers (default shows just running) and —-quiet /-q to list just their ids (useful for when you want to get all the containers).
+ `docker pull`
  —  Most of your images will be created on top of a base image from the Docker Hub registry. Docker Hub contains many pre-built images that you can pull and try without needing to define and configure your own. To download a particular image, or set of images (i.e., a repository), use docker pull.
+ `docker build`
  —  The docker build command builds Docker images from a Dockerfile and a “context”. A build’s context is the set of files located in the specified PATH or URL. Use the -t flag to label the image, for example docker build -t my_container . with the . at the end signalling to build using the currently directory.
+ `docker run`
  —  Run a docker container based on an image, you can follow this on with other commands, such as -it bash to then run bash from within the container. Also see Top 10 options for docker run — a quick reference guide for the CLI command. docker run my_image -it bash
+ `docker logs`
  —  Use this command to display the logs of a container, you must specify a container and can use flags, such as --follow to follow the output in the logs of using the program. docker logs --follow my_container
+ `docker volume ls`
   — This lists the volumes, which are the preferred mechanism for persisting data generated by and used by Docker containers.
+ `docker rm`
  —  Removes one or more containers. docker rm my_container
+ `docker rmi`
  —  Removes one or more images. docker rmi my_image
+ `docker stop`
  —  Stops one or more containers. docker stop my_container stops one container, while docker stop $(docker ps -a -q) stops all running containers. A more direct way is to use docker kill my_container, which does not attempt to shut down the process gracefully first.

Use them together, for example to clean up all your docker images and containers:

+ kill all running containers with `docker kill $(docker ps -q)`
+ delete all stopped containers with `docker rm $(docker ps -a -q)`
+ delete all images with `docker rmi $(docker images -q)`
