Custom health checks on argocd application discrepancy

[themaroqa]

Long Story short:
We need to build an external dashboard (for non tech people) that needs to provide the status of our argocd apps.
Those apps have a few peculiarities:

• can be scaled down to 0 replica by a cronjob
• can be disabled (it means the Deployment is not created)

In those 2 cases ArgoCD by default marks the application as Healthy, we wanted to change it to Suspended.

We correctly managed the the first case by adding a custom health check on Deployment (resource.customizations.health.apps_Deployment).

I thought managing the same would be pretty similar by creating a custom health check for argoproj.io_Application resources checking if a Deployment resource exists.

I actually implemented it but the App manifest doesn't mark the app as Suspended.

It marks instead the same (as you can see from the first screenshot) it as suspended in the AppOfApps application manifest

Here's the LUA script I used:

"resource.customizations.health.argoproj.io_Application" = <<-EOF
          hs = {}
          hs.status = "Progressing"
          hs.message = ""
          if obj.status ~= nil then
            if obj.status.health ~= nil then
              hs.status = obj.status.health.status
              if obj.status.health.message ~= nil then
                hs.message = obj.status.health.message
              end
            end
            -- Check if the application has no resources
            if obj.status.resources == nil then
              hs.status = "Suspended"
              hs.message = "No resources found"
            -- Check if the application has no Deployment resources
            else
              local hasDeployment = false
              for i, resource in ipairs(obj.status.resources) do
                if resource.kind == "Deployment" and resource.status == "Synced" then
                  hasDeployment = true
                  break
                end
              end
              if not hasDeployment then
                hs.status = "Suspended"
                hs.message = "Application has no Deployment resources"
              end
            end
          end
          return hs
        EOF

Is there something obvious I am missing? I cannot figure out why ArgoCD correctly change the status of the App to suspended only when "looking at it" from the AppOfApps perspective.
