Create GCP credentials¶

Prerequisites¶

Install gcoud CLI on your machine by following this guide.
Initialize gcloud CLI by following this guide.
Authorize cloud CLI by following this guide

Creating GCP credentials for Claudie¶

Create a GCP project:
```
gcloud projects create claudie-project
```

Set the current project to claudie-project:

gcloud config set project claudie-project

Attach billing account to your project:

gcloud alpha billing accounts projects link claudie-project (--account-id=ACCOUNT_ID | --billing-account=ACCOUNT_ID)

Enable Compute Engine API and Cloud DNS API:

{
  gcloud services enable compute.googleapis.com
  gcloud services enable dns.googleapis.com
}

Create a service account:

gcloud iam service-accounts create claudie-sa

Attach roles to the servcie account:

{
  gcloud projects add-iam-policy-binding claudie-project --member=serviceAccount:claudie-sa@claudie-project.iam.gserviceaccount.com --role=roles/compute.admin
  gcloud projects add-iam-policy-binding claudie-project --member=serviceAccount:claudie-sa@claudie-project.iam.gserviceaccount.com --role=roles/dns.admin
}

Recover service account keys for claudie-sa:

gcloud iam service-accounts keys create claudie-credentials.json --iam-account=claudie-sa@claudie-project.iam.gserviceaccount.com

DNS setup¶

If you wish to use GCP as your DNS provider where Claudie creates DNS records pointing to Claudie managed clusters, you will need to create a public DNS zone by following this guide.

GCP is not my domain registrar

If you haven't acquired a domain via GCP and wish to utilize GCP for hosting your zone, you can refer to this guide on GCP nameservers. However, if you prefer not to use the entire domain, an alternative option is to delegate a subdomain to GCP.

Input manifest examples¶

Single provider, multi region cluster example¶

Create a secret for Cloudflare and GCP providers¶

The secret for an GCP provider must include the following mandatory fields: gcpproject and credentials.

# The ./claudie-credentials.json file is the file created in #Creating GCP credentials for Claudie step 7.
kubectl create secret generic gcp-secret-1 --namespace=mynamespace --from-literal=gcpproject='project-claudie' --from-file=credentials=./claudie-credentials.json
