Document how to consume post-submit / nightly images

[sbueringer]

After the recent changes in #2051 we are now publishing images on every merge to the main and release branches.

Additionally for the main branch we tag images with a nightly tag and publish corresponding manifests (e.g. infrastructure-components.yaml & cluster-templates) to GCS.

Let's document where those images are available / how to consume them (e.g. via clusterctl if that is easily possible (?)).

Images:

• Build via: https://prow.k8s.io/?repo=kubernetes-sigs%2Fcluster-api-provider-vsphere&job=post-cluster-api-provider-vsphere-push-images
  • gcr.io/k8s-staging-capi-vsphere/cluster-api-vsphere-controller:main
  • gcr.io/k8s-staging-capi-vsphere/cluster-api-vsphere-controller:v20230802-v1.8.0-beta.1-8-g2fae0a97
  • gcr.io/k8s-staging-capi-vsphere/cluster-api-vsphere-controller:release-1.7
  • gcr.io/k8s-staging-capi-vsphere/cluster-api-vsphere-controller:v20230802-v1.7.1-25-g3ec8d66d
• Build via: https://prow.k8s.io/?job=cluster-api-provider-vsphere-push-images-nightly
  • gcr.io/k8s-staging-capi-vsphere/cluster-api-vsphere-controller:nightly_main_20230802

Manifests:

• Build via: https://prow.k8s.io/?job=cluster-api-provider-vsphere-push-images-nightly
  • Google Cloud UI: https://console.cloud.google.com/storage/browser/artifacts.k8s-staging-capi-vsphere.appspot.com/components/nightly_main_20230802

Hey @sbueringer

RE: documenting this process, I'm working on this for CAPA and wanted to see if this could be replicated for CAPV in some capacity, so we can somehow align how some of the providers document this. See: kubernetes-sigs/cluster-api-provider-aws#4968
LMK what you think here.
Thanks!

[sbueringer]

Nice, yup roughly the same should work for CAPV so we can document it the same way

[damdo]

Awesome, thank you!

Let's document where those images are available / how to consume them (e.g. via clusterctl if that is easily possible (?)).

I did some work in the past to use CAPI/CAPD nightly builds (see https://cluster-api.sigs.k8s.io/clusterctl/developers.html?highlight=nightl#nightly-builds)
We could probably build up on this work. Happy to pair if it can help

[sbueringer]

Interesting. Now that you're referring to clusterctl, I remember this one recent PR: https://github.com/kubernetes-sigs/cluster-api/pull/9797/files
