Hi folks,

Just a quick tip on how to keep a docker container running. Assuming you set up a docker container and you just want to do some inspections on the container before making it run its single long-running command, you may realize that the container will exit with exit code 0 if there is no “command” flag. How then do you keep the container alive without its intended long-running command?

You can do this by using a command like:

command: tail -f /dev/null

Then once you are through with your inspection you can remove that command and add the actual desired one.

That’s all for now. Till next time, happy software development.
