Build a Docker image
docker build -t NAME .
List Docker Images
List Running Docker Containers
List All Docker Containers, includig the ones that were stopped
docker ps -a
Run a docker image in an interactive mode and open /bin/bash
docker run -it IMAGE /bin/bash
Run the Docker image called IMAGE as the container called NAME in an interactive mode. Attach the current working directory in the host filesystem to the /opt in the container.
docker run -it -v $(pwd):/opt --name NAME IMAGE
List all the docker containers in quiet mode - CONTAINER IDs only
docker ps -aq
Remove docker container by DOCKER ID
docker rm DOCKER_ID
Combine the above two and remove all exited (stopped) the Docker containers:
docker rm $(docker ps -aq)
docker run -it -d -p 8080:80 sudoku /bin/bash
Attach to running container based on CONTAINER ID that can be listed by docker ps -a.
docker attach CONTAINER_ID
Then we can exit the container.
Once we havd a Dockerfile in our GitHub project we can configure Docker to host our public image. For this we need to register on the Docker HUB. In there we need to click on Create/Create Automated Build in the menu. If we have not linked our GitHub account yet then we need to do it now. (See Configure automated builds on Docker Hub for further details.)

Where xxxx is the Access token you generate in your Digital Ocean account. docker-sandbox is an arbitrary name that will be used as the name of the VPS on Digial Ocean.
$ docker-machine ls $ docker-machine ip docker-sandbox $ docker-machine inspect docker-sandbox
There all Run locally and lists the machne we have in the cloud and maybe also locally or inspect the configuration of one of the machines.
docker-machine env docker-sandbox
eval $(docker-machine env docker-sandbox)
