We have a Kubernetes cluster running on AWS Elastic Kubernetes Service.

In this cluster, we have an application which is usually working fine but sometimes our monitoring system notifies about unhealthy pods:

Check pods:

$ kk -n eks-prod-1-web-projectname-admin-backend-ns get pod
NAME READY STATUS RESTARTS AGE
bttrm-web-projectname-admin-backend-64648597fc-9j29n 1/1 Running 0 43m
bttrm-web-projectname-admin-backend-64648597fc-kptjj 1/1 Running 0 43m
bttrm-web-projectname-admin-backend-7f4b5bdb4c-wlbjf 0/1 Evicted 0 12d
bttrm-web-projectname-admin-backend-8478d778f9–5mrnc 0/1 Evicted 0 15d

Here we can see that two pods are in the Evicted status — let’s go to see what is going on.
