Why does `docker exec -it bash` sometimes fail with 'executable file not found'?

This happens frequently when dealing with minimalist 'Alpine' images. Alpine does not have `bash` installed to save space. You must use the standard, more primitive shell instead: `docker exec -it sh`.

Can I clear the logs if they get too big?

You cannot clear them directly via the CLI without restarting the container. In production, you must configure 'Log Rotation' in the Docker Daemon settings (`daemon.json`) to automatically truncate log files when they reach a certain size (e.g., 50MB).

What do the `-i` and `-t` flags actually mean?

`-i` (Interactive) keeps the Standard Input (stdin) open, allowing you to type commands. `-t` (TTY) allocates a pseudo-terminal, formatting the output so it looks like a real terminal with colors and proper spacing. They are almost always used together as `-it`.
