Delete pods using kubectl containing a substring

Question

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?

Answer 1

You can run a simple command:

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

Answer 2

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
