How is a container launched using command line?

Starting a container using the command line is usually done with Docker. The main command to run a container looks like this:

docker run [options] <image_name> [command]

Example of running a container with an interactive terminal:

docker run -it ubuntu /bin/bash

Here:

• -it — interactive mode with terminal,
• ubuntu — image name,
• /bin/bash — command that runs inside the container.

You can also specify ports, volumes, and environment variables through additional options.
