Jumping onto the train. Not exactly a project but a tip that comes in handy often.

Day to day I'm often working with a slew of containers, occasionally I'll wish I had exposed a port on it earlier.

In this case it was a production instance that entered a failure state which was intermittent and we've been unable to reproduce it. Restarting to open the port is out.

Using some socat magic you can force open a port:
