unknown field "includeTemplates"

[Eric-zch]

This is related to configuration in file https://github.com/CrunchyData/postgres-operator-examples/blob/main/kustomize/install/default/kustomization.yaml

I tried to apply it in my openshift with version 4.14.21, I got error message: error: json: unknown field "includeTemplates"

oc apply --server-side -k kustomize/install/default
error: json: unknown field "includeTemplates"

Hey @Eric-zch, sorry you're running into this. I have a hunch, but just to double-check, what's the output you get for oc version --client?

I haven't updated my oc in a while, so here's what I get if I just use what's on my path:

> oc version --client
Client Version: 4.10.17
> oc kustomize ../crunchydata/pgo-examples-june/kustomize/install/default
error: json: unknown field "includeTemplates"

But when I download the oc for 4.14, I get

> ./oc version --client
Client Version: 4.14.27
Kustomize Version: v5.0.1

And the oc kustomize command produces the expected YAML.

We have a section in our docs about using older kubectl or kustomize, but we don't talk about oc there; if this solves the problem for you, we might want to add a line to the docs about that.
