There are a number of input variables that Terraform expects in an [name].auto.tfvars file. I just use secrets.auto.tfvars.
- primary_account_email = "primary email for Google Cloud account"
- project = "internal Google Cloud project ID"
- master_authorized_networks_config_ip = "an IP address that should have access to the control plane"
- github_workload_assertion = "assertion constraint for a GitHub integration"
- github_workload_principal = "principalSet name for a GitHub integration"
- zones = "list of domain names to be managed by external-dns"
Just run terraform plan, and if everything looks OK, run terraform apply.
