How to use UpdateStatus

[basilfx]

I'm trying to update the status of a (custom) entity, but I don't see how I should use it properly. Can you provide an example?

I have the following code:

var deployment = new V1Deployment()
{
    ...
}

await _kubernetesClient.UpdateStatus(deployment);

Which gives me the following error:

The type 'k8s.Models.V1Deployment' cannot be used as type parameter 'TResource' in the generic type or method 'IKubernetesClient.UpdateStatus<TResource>(TResource)'. There is no implicit reference conversion from 'k8s.Models.V1Deployment' to 'k8s.IStatus<object>'.

I have the same problem with a custom entity that was defined as follows:

public class V1MyEntity : CustomKubernetesEntity<V1Alpha1ConnectorSetSpec, V1Alpha1ConnectorSetStatus>
{
    ...
}

I think this error is because UpdateStatus expects an instance that implements IStatus<object>: https://github.com/buehler/dotnet-kubernetes-client/blob/master/src/DotnetKubernetesClient/IKubernetesClient.cs#L130

I'm using this library via the dotnet-operator-sdk (version 4.0.20).

@buehler can you help me with this question?

Hey @basilfx

Sorry, I did not see the question in the first place!

Exactly, to update the status of an object, it must inherit the status interface. At least this is what I was expecting. The reason is, that CRD's are generated in a unique way with a status object. If this object is not generated with the updateable status object, updating the status only is not possible.

But when you use the custom entity, it should generally be possible (when you generate the CRD with my SDK at least)

Do you use the .net sdk (https://github.com/buehler/dotnet-operator-sdk)?

When we have a look at the code:
https://github.com/buehler/dotnet-kubernetes-client/blob/master/src/DotnetKubernetesClient/KubernetesClient.cs#L245-L258

This uses "ReplaceClusterCustomObjectStatus"

I just had a look at the base code... in theory, we could insert an object there (instead of IStatus).
Maybe this would work.

I don't see how that works.

I am using dotnet-operator-sdk, and the custom entity I am using is as shown above. Do you have an example that works?

Hmm weird. yes: https://github.com/smartive/hosted-database-operator/blob/f75a127fc32dddd7268cc5ad830c387a274ddd80/src/HostedDatabaseOperator/Controller/ClusterDatabaseHostController.cs#L94-L127 this is working. But I have a CRD instead of V1Deployment.

I think I need to investigate this matter
