Comment on Help with understanding memory usage discrepancy

Most of those containers are probably grabbing more memory than they actually need. Consider applying some resource constraints to some of them.

Dozzle is an excellent addition to your docker setup, giving you live performance graphs for all your containers. It can help a lot with fine tuning your setup.

It took a bit of trial and error with Portainer, but under Runtime & Resources, you can adjust the amount of needed resources:

Shared memory size

Memory reservation (MB)

Memory limit (MB)

Maximum CPU usage

  You can also set these limits in your compose file, if you use compose (which you should).

    Sure, it’s just easier for me to tweak in Portainer. But, yeah. There are many ways to skin the cat.
