echo “deb https://apt.dockerproject.org/repo ubuntu-xenial main” | sudo tee /etc/apt/sources.list.d/docker.list
sudo apt-get update
apt-cache policy docker-engine
You should see output similar to the follow:
Output of apt-cache policy docker-engine
docker-engine:

sudo apt-get install -y docker-engine
sudo systemctl status docker
The output should be similar to the following, showing that the service is active and running:

now you must logout to ensure all privilage is write
run : runs an image
start : starts a container.
The docker run doc does mention: The docker run command first creates a writeable container layer over the specified image, and then starts it using the specified command.
That is, docker run is equivalent to the API /containers/create then /containers/(id)/start. You do not run an existing container, you docker exec to it (since docker 1.3). You can restart an exited container.

You will need to save the docker image as a tar file:
docker save -o <save image to path> <image name>
Then copy your image to a new system with regular file transfer tools such as cp or scp. After that you will have to load the image into docker:
docker load -i <path to image tar file>
PS: You may need to sudo all commands.
docker run –net=”bridge” (default)
docker run –net=”host”
If you do “docker attach “container id” you get into the container. To exit from the container without stopping the container you need to enter “Ctrl+P+Q” better to Ctrl+P and Ctrl+Q
