Hello Rancher team, I have a Rancher cluster that is deployed on top of a Kubernetes K3s cluster. Currently, the disk usage on the worker VM/instance has reached 80%. Do you have any recommendations for the best cleanup practices to reduce disk usage for cleaning up logs on a VM/instance running K3s. I am using Ubuntu.

This is for general linux, but I use journalctl --vacuum-size=0B or journalctl --vacuum-time=1s often

have you looked at

imageGCHighThresholdPercent

and

imageGCLowThresholdPercent

https://kubernetes.io/docs/reference/config-api/kubelet-config.v1beta1/ You can also manually run

crictl rmi --prune

to remove unused container images to free up disk usage

Is it safe to run the following commands on a worker node?

sudo journalctl --vacuum-time=7d

sudo k3s crictl rmi --prune

I run

crictl rmi --prune

daily Never done the vacuum command
