Kafka Cluster configurationInfo.arnSelector property incorrectly applies Kafka Configuration arn

[vgiannone3]

What happened?

I created a crossplane composition which creates Kafka Configuration and Cluster resources. In order to link the two, I used the configurationInfo.arnSelector property in the cluster resource definition, with a match label.

After applying the composition, the configuration resource is created, and then the configuration arn property for the cluster is updated, but not with the arn. It is updated with the name of the Configuration resource. This puts the Cluster resource into a bad state, where it is reporting that the arn does not exist.

As a workaround, I delete the Cluster resource, and once crossplane creates it again, the arn is correctly set. To make this automated, I created a status variable within the composite resource definition, and set the status to the arn. This works for now, but it would be great if the selector worked as advertised.

How can we reproduce it?

Refer to the description above.

What environment did it happen in?

• Crossplane version: 1.9.0
• Provider-aws version: 0.29.0
• Cloud provider: aws
• Kubernetes version: 1.22
• Kubernetes distribution: AWS EKS

I am also using ArgoCD as the GitOps tool. It's version is 2.3.3

Could you please do

kubectl get configuration.kafka

I see

a504ae8-kafkacluster-2-config   True    True     arn:aws:kafka:reg:123:configuration/kafkacluster-2-config/uuid-4

If it's not True/True, then kubectl describe it.

Finally,

k describe cluster.kafka

(The securitygroup had a bug so it took a while before we fixed that, you should not see the same message)
