test workflow fails after bootstrap - Failed initializing schema about flux2-kustomize-helm-example

[ogomezm]

I am having the same issue and tried to workaround it without success.

First thing i did was trying to ignore-missing-schemas in the kubeval command scripts/validate.sh
kubeval ${file} **--ignore-missing-schemas** --strict --additional-schema-locations=file:///tmp/flux-crd-schemas

After doing that I am able to progress yet having the next issue.

As you can see it detects missing metadata in the kustomization.yaml...

I then added the a metadata field in the kustomization.yaml

metadata:
  name: flux

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
metadata:
  name: flux
resources:
- gotk-components.yaml
- gotk-sync.yaml

After doing this I've got and exit 1 and the same error from the begining ;).

PASS - ./clusters/production/apps.yaml contains a valid Kustomization (flux-system.apps)

Error: Process completed with exit code 1.

Then I tried downloading the missing schema

curl -sL -o /tmp/flux-crd-schemas/master-standalone-strict/customresourcedefinition-apiextensions-v1.json https://raw.githubusercontent.com/instrumenta/kubernetes-json-schema/master/master-local/customresourcedefinition-apiextensions-v1.json

I also had to add the following base dependency of the schema.

curl -sL -o /tmp/flux-crd-schemas/master-standalone-strict/_definitions.json https://raw.githubusercontent.com/instrumenta/kubernetes-json-schema/master/master-local/_definitions.json

Then I had an exit 1 with no more details.

After that i removed the --ignore-missing-schemas from the kubeval command in scripts/validate.sh as the dependencies should be already in place.

kubeval ${file} --strict --additional-schema-locations=file:///tmp/flux-crd-schemas

I got the same result. There weren't schema missing errors yet the exit code 1.
There were some warnings in the gotk-components.yaml file flux bootstrap pushes into clusters/staging/flux-system.

These are the warnings i got.
