Is there an include directive for Kubernetes yaml resource definitions?

Question

Consider the following ConfigMap definition, in, say, foo.yml:

apiVersion: v1
kind: ConfigMap
metadata:
  name: foo-data
data:
  foo.json: |-
    {
      "foo": "foo",
      "bar": 42
    }

Is there a way to load the foo.json data from an external file, instead of inlining it in the template? It would be nice if I could put the data in a file foo.json next to foo.yml, reference it somehow, and have K8s figure it out when I apply the template.

Is that possible? How?

If not, is the feature on the roadmap?

Answer 1

Afaik there is no build-in templating as for now but you can use ansible templating capabilities with k8s yaml files saute or together with e.g. k8s plugin.

Works like a charm :)
