1. Redis has outdated specs for GKE Autopilot Clusters:

Error from server (GKE Warden constraints violations): error when creating "redis-ha-1_manifest.yaml": admission webhook "warden-validating.common-webhooks.networking.gke.io" denied the request: GKE Warden rejected the request because it violates one or more constraints.
Violations details: {"[denied by autogke-pod-limit-constraints]":["workload 'redis-ha-1-haproxy' cpu requests '250m' is lower than the Autopilot minimum required of '500m' for using pod anti affinity."]}
Requested by user: '<id>', groups: 'system:authenticated'.

Changing cpu: 100m to cpu: 500m was needed.

2. The code that was used to generate the helm template seems to have copied the name of the pointer to the variable rather than the label itself:
   • https://github.com/GoogleCloudPlatform/click-to-deploy/blob/master/k8s/redis-ha/chart/redis-ha/templates/haproxy-deployment.yaml#L14
   • https://github.com/GoogleCloudPlatform/click-to-deploy/blob/master/k8s/redis-ha/chart/redis-ha/templates/redis-statefulset.yaml#L5

The helm chart / Application CRD seems to be fairly outdated yet GCP seems to be using this as the click-to-deploy solution in https://console.cloud.google.com/kubernetes/application, is there a private fork that is being used?
