ArgoCD "custom health check"

[MPV]

Anyone else using ArgoCD to deploy this operator?

I'd like to suggest we create an ArgoCD "Custom Health Check" for this operator.

Read more about what that is here: https://argo-cd.readthedocs.io/en/stable/operator-manual/health/

And here's how to add one: https://argo-cd.readthedocs.io/en/stable/operator-manual/health/#way-2-contribute-a-custom-health-check

Essentially something like this:

$ cd github.com/argoproj/argo-cd
$ cat resource_customizations/acid.zalan.do/postgresql/health.lua
hs = {}
if obj.status == nil or obj.status.PostgresClusterStatus == nil then
  hs.status = "Progressing"
  hs.message = "Waiting for postgres cluster status..."
  return hs
end

if obj.status.PostgresClusterStatus == "Running" then
  hs.status = "Healthy"
  hs.message = obj.status.PostgresClusterStatus
  return hs
end

if obj.status.PostgresClusterStatus == "Creating" or obj.status.PostgresClusterStatus == "Updating" then
  hs.status = "Progressing"
  hs.message = obj.status.PostgresClusterStatus
  return hs
end

hs.status = "Degraded"
hs.message = obj.status.PostgresClusterStatus
return hs

How to show the resources created by the operator?

• @MPV, how can I show the StatefulSets and Services associated with the Database?
  • ArgoCD is just showing the postgres crd...

@marcellodesales https://github.com/zalando/postgres-operator/issues/498 is required for those resources to show up (as they’re not created by ArgoCD but by the operator — ArgoCD requires this owner reference link to understand that they are related).

@MPV

According to https://github.com/zalando/postgres-operator/issues/1766#issuecomment-1028168636, we just need to add labels... (See Argo's latest discussion on the thread)... thank you!

Are there any plans to provide this health check to argo-cd?
