What will happen to evicted pods in kubernetes?

Solution 1:

A quick workaround I use, is to delete all evicted pods manually after an incident. You can use this command:

kubectl get pods --all-namespaces -o json | jq '.items[] | select(.status.reason!=null) | select(.status.reason | contains("Evicted")) | "kubectl delete pods \(.metadata.name) -n \(.metadata.namespace)"' | xargs -n 1 bash -c

Solution 2:

To delete pods in Failed state in namespace default

kubectl -n default delete pods --field-selector=status.phase=Failed

Solution 3:

Evicted pods should be manually deleted. You can use following command to delete all pods in Error state.

kubectl get pods --all-namespaces --field-selector 'status.phase==Failed' -o json | kubectl delete -f -

Solution 4:

Depending on if a soft or hard eviction threshold that has been met, the Containers in the Pod will be terminated with or without grace period, the PodPhase will be marked as Failed and the Pod deleted. If your Application runs as part of e.g. a Deployment, there will be another Pod created and scheduled by Kubernetes - probably on another Node not exceeding its eviction thresholds.

Be aware that eviction does not necessarily have to be caused by thresholds but can also be invoked via kubectl drain to empty a node or manually via the Kubernetes API.
