Cert Manager Helm Operator

A Kubernetes Operator based on the Operator SDK (Helm version) to configure official cert-manager operator helm chart, so it can be installed via OLM without having to do any change on current Helm Charts.

The usual Helm Chart file values.yaml, like:

prometheus:
  enabled: true
  servicemonitor:
    enabled: true
    targetPort: 9402
    path: /metrics
    interval: 30s
podDnsConfig:
  nameservers:
    - 1.1.1.1
    - 8.8.8.8
resources:
   requests:
     cpu: 10m
     memory: 96Mi
   limits:
     cpu: 100m
     memory: 256Mi

Need to be encapsulated into a new custom resource called OperatorConfig:

apiVersion: operatorconfigs.operator.cert-manager.io/v1alpha1
kind: OperatorConfig
metadata:
  name: cluster
spec:
  prometheus:
    enabled: true
    servicemonitor:
      enabled: true
      targetPort: 9402
      path: /metrics
      interval: 30s
  podDnsConfig:
    nameservers:
      - 1.1.1.1
      - 8.8.8.8
  resources:
   requests:
     cpu: 10m
     memory: 96Mi
   limits:
     cpu: 100m
     memory: 256Mi

So the operator will create all helm chart resources, using the custom resource name as a prefix for all resources names.

Quick release

You can easily generate the operator for any particular version of the Cert Manager Helm Chart using the container-build target with a specific VERSION.
