## Introduction
|
|
|
|
I was playing with the percona xtradb operator on one of my test clusters last week and left it in a state where mysqld error logs were piling up over the week-end. On Monday morning my nodes had their file systems full and I discovered what kubernetes evicted pods were : pods that fail when a node's resources get constrained.
|
|
|
|
My problem is : these evicted pods lingered, so I looked for a way to clean them up.

## How to delete all evicted pods
|
|
|
|
My google fu directed me towards several commands similar to the following, but they all had a thing or another that did not work properly. Here is the one I pieced together from these various sources :
|
|
```sh
|
|
kubectl get pods --all-namespaces -o json |
|
|
jq '.items[] | select(.status.reason!=null) |
|
|
select(.status.reason | contains("Evicted")) |
|
|
"kubectl -n \(.metadata.namespace) delete pod \(.metadata.name)"' |
|
|
xargs -n 1 bash -c
|
|
```
