What do the -it flags in docker run -it signify?

The -it flags in the context of the docker run command are crucial for running a container interactively. Specifically, the -i flag stands for "interactive," which allows you to keep the standard input (STDIN) open even if not attached, enabling you to send commands to the container. The -t flag stands for "pseudo-TTY," which allocates a terminal interface for the container, allowing for a more user-friendly command line experience, similar to what you would experience in a regular terminal.

When used together, -it allows you to interact with the container in real-time, making it possible to run commands as if you were in a shell. This functionality is particularly useful for debugging, development, or when you want to run applications that require user input within the container. Thus, the answer reflects the intended use of these flags, focusing on their role in facilitating an interactive shell within the container environment.
