Hi @zioproto. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

This is how I tested this:

cd cluster-api-operator/hack/charts
helm template --set infrastructure=azure:v1.13.0   \
                         --set addon=helm --set cert-manager.enabled=true \
                         --set image.manager.tag=v0.8.1 \
                         --set manager.featureGates.EXP_MACHINE_POOL=true  \
                         --set manager.featureGates.CLUSTER_TOPOLOGY=true \
                         --set manager.featureGates.EXP_CLUSTER_RESOURCE_SET=true \
                         --wait capi ./cluster-api-operator \
                         | grep -C 10 featureGates

This is the output template I got:

kind: InfrastructureProvider
metadata:
  name: azure
  namespace: azure-infrastructure-system
  annotations:
    "helm.sh/hook": "post-install"
    "helm.sh/hook-weight": "2"
spec:
  version: v1.13.0
  manager:
    featureGates:
      CLUSTER_TOPOLOGY: true
      EXP_CLUSTER_RESOURCE_SET: true
      EXP_MACHINE_POOL: true

@Fedosin - looks like all the tests pass. Appreciate you taking a look.

[Fedosin]

I think it's okay for now. But in the future I want to separate this into 2 charts: one to manage CAPI operator and another to deploy provider CRs with different parameters.

cd cluster-api-operator/hack/charts
helm template --set infrastructure=azure:v1.13.0
--set addon=helm --set cert-manager.enabled=true
--set image.manager.tag=v0.8.1
--set manager.featureGates.EXP_MACHINE_POOL=true
--set manager.featureGates.CLUSTER_TOPOLOGY=true
--set manager.featureGates.EXP_CLUSTER_RESOURCE_SET=true
--wait capi ./cluster-api-operator
| grep -C 10 featureGates

Everything works but for the sake of completeness the correct way to set this parameters is:

cd cluster-api-operator/hack/charts
helm template --set infrastructure=azure:v1.13.0   \
                         --set addon=helm --set cert-manager.enabled=true \
                         --set image.manager.tag=v0.8.1 \
                         --set manager.featureGates.MachinePool=true  \
                         --set manager.featureGates.ClusterTopology=true \
                         --set manager.featureGates.ClusterResourceSet=true \
                         --wait capi ./cluster-api-operator \
                         | grep -C 10 featureGates
