Custom health-checks for resources with wildcard for AWS Controllers for Kubernetes (ACK)

[devzaak]

As part of our argo system we have a lot of resources created by AWS Controllers for Kubernetes (ACK)
For this we have implemented a simple health check lua using wildcard to target all resource under *.services.k8s.aws/*

        "*.services.k8s.aws/*":
          health.lua: |
            hs = {}
            if obj.status ~= nil then
              if obj.status.conditions ~= nil then
                for i, condition in ipairs(obj.status.conditions) do
                  if condition.type == "ACK.ResourceSynced" and condition.status == "True" then
                    hs.status = "Healthy"
                    hs.message = condition.message
                    return hs
                  end
                  if condition.type == "ACK.ResourceSynced" and condition.status == "False" then
                    hs.status = "Progressing"
                    hs.message = condition.reason
                    return hs
                  end
                  if condition.type == "ACK.ResourceSynced" and condition.status == "Unknown" then
                    hs.status = "Degraded"
                    hs.message = condition.reason
                    return hs
                  end
                end
              end
            end

            hs.status = "Progressing"
            hs.message = "Waiting for Status conditions"
            return hs

Unfortunately this does not seem to be working, in objects status I can see that condition is met, but the status is not applied.
Currently We are thinking it might be due to access to the standard Lua libraries being disabled by default.

The (health check documentation)(https://github.com/schakrad/argo-cd/blob/master/docs/operator-manual/health.md) shows an example of how to enable it for a specific resource/kind but I can't seem to figure out how to enable it for a wildcard based check?

tried with adding health.lua.useOpenLibs: true that also did not make it work.

....
"*.services.k8s.aws/*":                                                                                                                                                                                                                          
   health.lua.useOpenLibs: true                                                                                                                                                                                                                   
   health.lua: |                                                                                                                                                                                                                                  
     hs = {}                                                                                                                                                                                                                                      
     if obj.status ~= nil then
....

any ideas how to make this work? or globally allow the useOpenLibs?
thank you

[stefanmcshane]

Hey @aslezak, did you ever get this to work globally for all resources?

[patpicos]

im also interested in this question...

[devzaak]

No, unfortunately never did. We used a different approach in the end

[patpicos]

ive tried the equivalent of the following under resource.customizations and the libraries were enabled...

"*.services.k8s.aws/*":                                                                                                                                                                                                                          
   health.lua.useOpenLibs: true                                                                                                                                                                                                                   
   health.lua: |                                                                                                                                                                                                                                  
     hs = {}                                                                                                                                                                                                                                      
     if obj.status ~= nil then
