I was wondering if it's possible to refer to image field in Kubernetes deployment yaml file, as
env:
- name: VERSION
value:
valueFrom:
containerField: spec.image
Please let me know. Thank you.
image
value in pod definition cannot be passed as environment variable using fieldRef
.
The only supported values are metadata.name, metadata.namespace, metadata.labels, metadata.annotations, spec.nodeName, spec.serviceAccountName, status.hostIP, status.podIP, status.podIPs
and resource
fields (memory, cpu request/limits) and container ephemeral storage limit/request.
As a workaround it can be passed using labels and then passing this label as an environment variable, example:
env:
- name: VERSION
valueFrom:
fieldRef:
fieldPath: metadata.labels['version']
