Cleaning old images from worker nodes

I have a small 3 node cluster, and 2 worker nodes seem to be keeping old images on them, and it’s eating up a lot of space. I’ve been combing through all the Rancher docs and google to try and find a way to clear these images, or why Rancher isn’t doing it, but I have not been able to find anything regarding this specific issue. I’ve tried cordoning and draining, then a reboot, but no change.

Thought maybe i could just go on the VM and use docker to remove images, but docker is not installed, so i’d rather not put it on there if I don’t have to. Any suggestions?

Rancher 2.6.6

run crictl rmi on the nodes.
