Unable to determine type when creating Ingress resource (apiVersion==networking.k8s.io/v1)

[kmadisa]

I get an error when I try to create a Ingress resource in my test.

Sample ingress.yaml file:

---
# Source: ska-tango-base/templates/ingress.yaml
# use Nginx
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: rest-api-ska-tango-base
  namespace: default
  labels:
    app: ska-tango-images
    component: tango-rest
    function: tango-http-interface
    domain: tango-configuration
    intent: enabling
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/rewrite-target: /$1
    app.gitlab.com/app: CI_PROJECT_PATH_SLUG
    app.gitlab.com/env: CI_ENVIRONMENT_SLUG
spec:
  rules:
    - http:
        paths:
        - path: /default/(tango/rest/.*)
          pathType: Prefix
          backend:
           service:
            name: ska-tango-base-tango-rest
            port:
              number: 8080

Sample test_ingress.py test:

import pytest


@pytest.mark.namespace(create=True, name='test')
@pytest.mark.applymanifests('.', files=[
    'ingress.yaml'
])
def test_ingress(kube):
    """An example test against an tangodb deployment."""

    # wait for the manifests loaded by the 'applymanifests' marker
    # to be ready on the cluster
    kube.wait_for_registered(timeout=30)

    ingresses = kube.get_ingresses()
    tango_ingress = ingresses.get('rest-api-ska-tango-base-RELEASE-NAME')
    assert tango_ingress is not None
    assert tango_ingress.is_ready()

The error that I get when I run pytest -s test_ingress.py --kube-config=~/.kube/config:
