Google Cloud Platform

Overview

CCX supports Google Cloud Platform (GCP) as a cloud provider.

It requires the following things enabled on the GCP side: - A GCP project must be created. - A service account must be created with the necessary permissions. The list of permissions is as follows:

compute.disks.create
compute.disks.delete
compute.disks.get
compute.disks.list
compute.disks.use
compute.instances.create
compute.instances.delete
compute.instances.get
compute.instances.list
compute.networks.create
compute.networks.delete
compute.networks.get
compute.networks.list
compute.networks.use
compute.zones.get
compute.zones.list
compute.operations.get
compute.operations.list

- A VPC network may be created for CCX, where CCX will create necessary rules. If no VPC network is created, CCX will use default. - Cloud Storage Service account HMAC key must be created in Cloud Storage > Settings > Interoperability.

This Access key and Secret pair will be used to create a Kubernetes secret that will be used for backups.

• A valid image id must be provided. This is typically a public image id of ubuntu 22.04.

Configuration

Deployer configuration

In the deployer configuration (ccx-values-deployer.yaml) we configure how CCX will access the GCP APIs.

gcp_vendor:
  project: gcp-project # replace with created project name
  image_id: projects/ubuntu-os-cloud/global/images/ubuntu-2204-jammy-v20240614 # replace with the image id
  network: default # replace with the network name if created
  s3:
    enabled: true # needed for backups

europe-west1 is the region name and europe-west1-b, europe-west1-c, europe-west1-d are the availability zones.

Replace x.x.x.x/x with the CIDR of the IP address that the CCX cluster will use to access the database nodes.

Cloud configuration

To configure the cloud details like volumes, instance types, the cloud name we will define the new section in ccx-values-config.yaml.

Secrets

For the GCP S3 backup, we need to create a Kubernetes secret that will be used for backups.

yaml apiVersion: v1 kind: Secret metadata: name: gcp-s3 type: Opaque data: GCP_S3_ACCESSKEY: BASE64_ENCODED_CLOUD_STORAGE_ACCESS_KEY GCP_S3_SECRETKEY: BASE64_ENCODED_CLOUD_STORAGE_HMAC_SECRET_KEY

Replace BASE64_ENCODED_CLOUD_STORAGE_ACCESS_KEY and BASE64_ENCODED_CLOUD_STORAGE_HMAC_SECRET_KEY with the base64 encoded values of the access key and secret key from the Cloud Storage Service account HMAC key.

For example, using the output of: echo -n "MY_VALUE" | base64
