Rancher crashloopback daily issue

rafael.sisweb · January 5, 2021, 5:56pm

Hi we are facing problems with rancher 2.4.5.
We had the rancher application stuck with crashloopbackoff after a few hours running and get back healthy after hours of downtime.

This behaviour starts 3 weeks ago without any previus occurence for almost 400days of cluster operation.

I appreciate any tips or a way to fix that.

Thanks all.

We’ve got this log of rancher (cattle-system).

Please share more information on the setup:

On what cluster is Rancher running (RKE/K3S/other, what k8s version)
Does it happen every day around the same time or different times/random
What do the k8s components log at the time it happens (especially etcd/kube-apiserver/kubelet)
What are the specs of the machines of the cluster Rancher is running on and how many resources are there in the cluster (apps/pods/secrets/configmaps etc)

Hi there! Thanks for the quick reply. Here it goes:

On what cluster is Rancher running (RKE/K3S/other, what k8s version)
k8s 1.15 - RKE latest
Does it happen every day around the same time or different times/random
Everyday, random times
What do the k8s components log at the time it happens (especially etcd/kube-apiserver/kubelet)
Etcd seems normal as usual
Kubelet seems like this:

Got exactly at this moment. Results may vary depending on requests/attempts to make it work
What are the specs of the machines of the cluster Rancher is running on and how many resources are there in the cluster (apps/pods/secrets/configmaps etc)
On that cluster - by the way… this cluster is a intermediate cluster used to have access to the k8s API which means the server entry on kubeconfig is that cluster endpoint - we have 3 nodes with 16vCPU and 64GB RAM with essential services:

Can you check memory usage of Rancher and cattle-cluster-agent pod? How many resources are in the cluster? And do you have any info what happened 3 weeks ago that could have caused the issue (maybe onboarding new clusters/projects which bumped the resource count)
