Problem: stackablectl stack install airflow fails with 503 Service Unavailable

[hosseinpirhadi]

I'm trying to install the Airflow stack using stackablectl, and the following error is returned:

ERROR failed with status 503 Service Unavailable

Caused by these errors:
1: failed to create Kubernetes client
2: failed to run GVK discovery
3: ApiError: "service unavailable\n"

CONTEXT:

    1-The airflow-operator has already been deployed and is running.
    2-Kubernetes is up, and I can interact with it via kubectl (e.g., kubectl get nodes works fine).
    3-I'm running on Rocky Linux with containerd.
    4-stackablectl version: 25.3.0
    5-kubectl version: Client Version: v1.29.15
                                  Kustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3
                                  Server Version: v1.29.15

Question:
What causes this 503 error in the context of GVK discovery?
Is there a known issue or workaround to allow stackablectl to proceed with the stack install?

Any help or pointers would be appreciated. Thanks!

Hi, can you provide the exact command and the stackablectl version you are using?

The error indicates that a failure is happening very early in the lifecycle of (in this case) a stack installation. It is pretty much the first step we need to take when trying to talk to the Kubernetes apiserver.

What would be really helpful is more detailed log output. You can set the log level with the -l parameter. I would recommend at least INFO.

This confirms my suspicion.

stackablectl immediately fails after starting to run the discovery. As previously mentioned this indicates that the cluster (or more specifically the apiserver) you are running against is not working properly. If you'd drop the log level even lower, we might be able to peek at the URLs being queried.

Also, is it possible for you to post these outputs as text for easier searchability?

I uploaded logs.txt, with debug level.
