[ameukam]

Define the VCL configuration needed to authenticate to GCS private bucket and use it as origin. This configuration leverage S3 authentification mechanism.
The endpoint is currently not publicly exposed.

I had to pass the variables manually while running terraform apply for this config.

To test. add to the /etc/hosts:

151.101.0.204   cdn.dl-sandbox.k8s.dev
2a04:4e42::204 cdn.dl-sandbox.k8s.dev

and run cd $(mktemp -d) && curl -fSsLv -O http://cdn.dl-sandbox.k8s.dev/release/v1.29.1/kubernetes-node-linux-amd64.tar.gz && tar -xvzf kubernetes-node-linux-amd64.tar.gz

Can we at least add a comment outlining how to obtain the values?

@BenTheElder We could use terraform to passe the values. Put the creds required in a GCP Secret and get them using https://registry.terraform.io/providers/hashicorp/google/latest/docs/data-sources/secret_manager_secret_version. This implies the operator to have some GCP permissions binded to the GCP secret.

SGTM, I'm also fine with manual (like deploying boskos resources...) as long as we leave some markdown covering how this works for the next people doing this :-)
