Bash Script: Clean Up Evicted Pods

If you use Spot Instances or have tight resource limits, you’ve seen them. Rows and rows of pods with status Evicted.

They don’t consume resources, but they are noise. They make kubectl get pods hard to read and can slow down some dashboards.

The Cleanup Command

Here is the command to delete only the pods that are Failed or Evicted, across all namespaces:

kubectl get pods -A | grep Evicted | awk '{print $1, $2}' | xargs -n2 bash -c 'kubectl delete pod $2 -n $1'

How it works

1. kubectl get pods -A: List everything.
2. grep Evicted: Filter for the noise.
3. awk '{print $1, $2}': Extract the Namespace ($1) and Pod Name ($2).
4. xargs: Pass them to the delete command.

Run this once a week, or add it to your CI/CD cleanup job. Keep your cluster tidy.
