Rotating Docker Log Files
Sometimes containers log a lot of things, and the logfile can become huge.
This happens because containers aren’t supposed to run for a long time but to be created/disposed regularly. Here’s how to fix this.
You have to instruct Docker, at launch, and tell how much you want the log file to grow before rotating and how many old logs you want to keep.
For example,
--log-opt max-size=50m --log-opt max-file=5
