Docker containers stop when their foreground process terminates, making debugging challenging. Five methods can keep containers running for debugging: overriding commands with interactive shells, using 'tail -f /dev/null', using 'sleep infinity', committing container state to new images, and wrapping entrypoints with custom scripts. Additional debugging practices include checking container logs and exit codes, using shell sessions to investigate environments, implementing monitoring systems, and considering process managers like supervisord for advanced scenarios.
