when creating first byoh cluster, its first controller node stuck with 'Installer config is not ready, requeuing'

[haiwu]

What steps did you take and what happened:
I followed the exact step in the quickstart guide, except I am using an external existing k8s cluster as its management cluster, and I am trying to create the first worker node k8s cluster. I have 2 VMs in the same vlan as the management cluster nodes, and I picked another free IP address in the same vlan as all these nodes (5 nodes in the management cluster, and 2 nodes for the new worker node cluster, they are all in the same vlan)

What did you expect to happen:
It should work to first join the first node to the new worker node cluster as controller node, then join the 2nd node to the new worker node cluster as a worker node.

Anything else you would like to add:
On manager side:

clusterctl describe cluster byoh-cluster

• Cluster-api-provider-bringyourownhost version: latest
• Kubernetes version: (use kubectl version --short):
  on the management server side:

kubectl version --short

Flag --short has been deprecated, and will be removed in the future. The --short output will become the default.
Client Version: v1.27.2
Kustomize Version: v5.0.1
Server Version: v1.27.2

• OS (e.g. from /etc/os-release): Debian Bullseye

Hey @haiwu, From the information above it seems like you are using a non-supported OS. Please note that CAP-BYOH only supports Ubuntu 20.04 OS

[haiwu]

@dharmjit : Where in the source code it would reject any non-Ubuntu 20.04 OS? How could I add support for another non-Ubuntu 20.04 OS? I saw in the TGIK video that there might be a way, but the docs here do not mention that..

[dharmjit]

How could I add support for another non-Ubuntu 20.04 OS

@haiwu Different OS installer implementations have to go here. The complex part is that with more OS/Versions, the complexity of maintaining agent code, artifacts distribution(bundles), and maintaining tests/CI will increase.

Could you let me know which OS are you trying to use BYOH with?

[haiwu]

@dharmjit: Yes, I have the patch for new OS tested ok already (with support for k8s 1.27), I will try to get ok from my side and put in a new PR later.
