Explanation

docker run Is the command to run the container, here we briefly explain the parameters used above.

-it: These are two parameters, a is -i: interactive operation, one is -t terminal. We intend to enter here bash to execute commands and return the results to see, so we need interactive terminals.
--rm: This parameter is to say after the vessel exit will be deleted. By default, the demand for troubleshooting, exit the container does not delete immediately, unless manually docker rm. We are here only just execute a command, look at the results, does not require troubleshooting and retention results, so use --rm to avoid wasting space.
ubuntu:16.04: This is a ubuntu:16.04 mirror image basis starting container.
bash: The image name is placed in command, here we want to have an interactive Shell, so use is bash.

After entering the container, we can operate under the Shell, execute any desired command. Here, we have implemented cat /etc/os-release, which is commonly used Linux command to view the current version of the system, from the returned results can be seen within the container is a Ubuntu 16.04.4 LTS system.

By the end we exit pulled out of the container.
