Delete pods using kubectl containing a substring-CodePudding

When I run the command kubectl get pods | grep "apisix", I get the following data

apisix-dev-78549978b7-pvh2v                           1/1     Running             6 (4m19s ago)   8m14s

Is there any way to delete all the pods containing the word apisix instead of mentioning every pod name in kubectl delete command?

CodePudding user response：

You can run a simple command:

kubectl delete pod $(kubectl get pod | grep apisix | awk '{print $1}')

A common way to select (and then, maybe delete) a set of Pods is via selector labels.

For example, assuming that a proper label app with value apisix exists:

# Find which Pods are selected (just to be sure)
kubectl get pod --selector=app=apisix

# Delete them (probably with --dry-run=client, if still unsure about what is selected)
kubectl delete pod --selector=app=apisix
