maas CAPI struggle

I’m having difficulty finding success with these instructions: https://documentation.ubuntu.com/canonical-kubernetes/capi/tutorial/getting-started/

I’ve even tried adding the infrastructure provider to clusterctl.yaml:

providers:
  - name: "maas"
    url: "https://github.com/spectrocloud/cluster-api-provider-maas/releases/download/v0.6.1/infrastructure-components.yaml"
    type: "InfrastructureProvider"

I don’t think it’s a networking issue since this works just fine:

root@k8s-vm:~# wget https://github.com/spectrocloud/cluster-api-provider-maas/releases/download/v0.6.1/infrastructure-components.yaml

What am I doing wrong here?

I was doing a few things wrong here.

First, I was using clusterclt v1.11.0 (because I like using the latest…) which wasn’t the one listed in the tutorial → v1.9.3. That might have had something to do with it.

Secondly, SpectroCloud’s MaaS infra provider is on v0.6.1 but it looks like they didn’t publish an amd64 image for it. Their GitHub tutorial says to use v0.5.0, which works.

I’m currently a lot further down the road, but still do not have a working k8s deployment because cluster-api keeps hitting 401 forbidden when hitting some of the MaaS API endpoints. I don’t think this is a cluster api issue, since I confirmed this with an admin API key and hitting the endpoints with curl.

Very frustrating user experience.
