I have a template part like:
spec:
containers:
- name: webinspect-runner-{{ .Values.pipeline.sequence }}
...
env:
- name: wi_base_url
valueFrom:
secretKeyRef:
name: webinspect
key: wi-base-url
- name: wi_type
valueFrom:
secretKeyRef:
name: webinspect
key: wi-type
The webinspect/wi_type
secret may be missing. I want the container also don't have the wi_type envvar or get a default value (better) when the secret is missing, but k8s just reports CreateContainerConfigError: couldn't find key wi-type in Secret namespace/webinspect
and the pod fails.
Is there a way to use a default value, or skip the block if the secret does not exist?
Two options, the first is add optional: true
to the secretKeyRef block(s) which makes it skip. The second is a much more complex approach using the lookup
template function in Helm . Probably go with the first:)
