RELATED_IMAGE_AUTHORINO env var

[eguzki]

What

Authorino image can be read from RELATED_IMAGE_AUTHORINO env var. Defaults to quay.io/kuadrant/authorino:latest

Required to specify the authorino image from the CSV manifest

The authorino image being used in the deployment is read from different sources with some order of precedence:

1. Authorino CR's spec.image
2. RELATED_IMAGE_AUTHORINO env var
3. Value set at the operator compilation time passed as ldflags -X github.com/kuadrant/authorino-operator/controllers.DefaultAuthorinoImage=VALUE
4. quay.io/kuadrant/limitador:latest

Verification steps

run cluster

kind create cluster --name authorino-operator-system

install CRDs

make install

run operator locally with specific RELATED_IMAGE_AUTHORINO env var.

RELATED_IMAGE_AUTHORINO=quay.io/kuadrant/authorino:v0.18.0 make run

Create authorino object without spec.image to deploy version from env var.

k apply -f - <<EOF
apiVersion: operator.authorino.kuadrant.io/v1beta1
kind: Authorino
metadata:
  name: authorino
spec:
  listener:
    tls:
      enabled: false
  oidcServer:
    tls:
      enabled: false
EOF

Check authorino's version is quay.io/kuadrant/authorino:v0.18.0

$ kubectl get deployments authorino -o jsonpath='{.spec.template.spec.containers[0].image}'

The response should be

quay.io/kuadrant/authorino:v0.18.0

Clean up

kind delete cluster --name authorino-operator-system
