Profile dependsOn and validateHealths

Managing multiple applications across different teams, each of them requiring the presence of the cert-manager, consider utilizing a ClusterProfile to deploy cert-manager centrally.

This approach enables other ClusterProfiles, responsible for deploying applications that depend on cert-manager, to leverage the dependsOn field to ensure the cert-manager is present prior to application deployment.

To guarantee that cert-manager is not only deployed but also functional, employ the validateHealths flag. The below ClusterProfile will deploy cert-manager in any cluster matching the label selector env=fv and subsequently wait for all deployments in the cert-manager namespace to reach a healthy state (active replicas matching requested replicas) before setting the ClusterProfile as provisioned.

        local hs = {healthy = false, message = "available replicas not matching requested replicas"}
        if obj.status and obj.status.availableReplicas ~= nil and obj.status.availableReplicas == obj.spec.replicas then
          hs.healthy = true
        end
        return hs
      end

Example: Nginx and Cert Manager

In the below example, the ClusterPofile to deploy the nginx ingress depends on the cert-manager ClusterProfile defined above.

kind: ClusterProfile
metadata:
  name: ingress-nginx
spec:
  clusterSelector:
    matchLabels:
      env: fv
  syncMode: Continuous
  helmCharts:
  - repositoryURL:    https://kubernetes.github.io/ingress-nginx
    repositoryName:   ingress-nginx
    chartName:        ingress-nginx/ingress-nginx
    chartVersion:     "4.8.4"
    releaseName:      ingress-nginx
    releaseNamespace: ingress-nginx
    helmChartAction:  Install
  dependsOn:
  - cert-manager
