How to run an Ubuntu Docker container and access the bash shell

This basic example tutorial will run an Ubuntu Docker container and the bash shell inside. To start with, run the docker run towards Ubuntu as shown here:

sudo docker run -it ubuntu /bin/bash

• sudo – if you are using a non-root user (which is recommended)
• the docker run command
• -it means to be interactive with tty
• Then the image name docker
• And the command you want to execute, in our case /bin/bash

Demo – docker run Ubuntu Bash shell

How to verify whether your docker Ubuntu container is running?

If you are inside the bash shell, as shown above, your container is running successfully.
