Docker run command
Use Docker run command to launch containers from an image. It provides a large number of options.
docker run [OPTIONS] IMAGE [COMMAND] [ARG...]
For example, run the hello-world example officially provided by Docker community to test your installation. Run command will also download the image from docker hub it not found locally.
$ sudo docker run hello-world
As a better use, you can use -i to keep STDIN open and -t to allocate a TTY to the container. You can also use -d to run container in detached (background) mode. I have also run bash shell as a startup script to the container.
$ sudo docker run -it -d ubuntu /bin/bash
