I'd like tests pods to persist after running helm test so that I can inspect the logs.
But in Helm 3, running helm test runs the tests, prints the results (success/failure), and then deletes the pods.
How can I get Helm to keep the pods around after test execution?
I was using a test Pod that included the "helm.sh/hook-delete-policy": hook-succeeded annotation. Here it is in a lightly-modified version of the test created by helm create:
apiVersion: v1
kind: Pod
metadata:
name: "{{ include "test-helm-logs.fullname" . }}-test-connection"
labels:
{{ include "test-helm-logs.labels" . | nindent 4 }}
annotations:
"helm.sh/hook": test-success
"helm.sh/hook-delete-policy": hook-succeeded
spec:
containers:
- name: wget
image: busybox
command: ['wget']
args: ['{{ include "test-helm-logs.fullname" . }}:{{ .Values.service.port }}']
restartPolicy: NeverRemoving the delete annotation allowed the pod to stick around for inspection.
