wasm shim image from env var

[eguzki]

what

In order to pin the wasm shim image from the manifest bundle, the image needs to be exposed in the manifests and read from an env var by the controller

Additionally, the operator configures the kuadrant core controller (aka kuadrant-controller) with the WASM_FILTER_IMAGE env var.

verification steps

run dev env

make kind-create-kuadrant-cluster

Create kuadrant CR

k apply -f - <<EOF
---
apiVersion: kuadrant.kuadrant.io/v1beta1
kind: Kuadrant
metadata:
  name: kuadrant-sample
spec: {}
EOF

Check that the kuadrant core controller has the wasm shim image url specified in the deployment object

k get deployments kuadrant-controller-manager -o jsonpath='{.spec.template.spec.containers[].env}' | yq_pretty
- name: LIMITADOR_NAMESPACE
  value: default
- name: LIMITADOR_NAME
  value: limitador
- name: WASM_FILTER_IMAGE
  value: oci://quay.io/kuadrant/wasm-shim:latest
