Preparing GCP infrastructure for installing DevOps Loop on GKE

You must set up the required Google Cloud Platform (GCP) infrastructure including DNS, a global static IP address, and RWX Storage, before deploying DevOps Loop on Google Kubernetes Engine (GKE).

Before you begin

You must have completed the following tasks:
  • Ensured that your GCP environment includes the required roles and APIs:
    • The service account used for the GKE cluster must have the roles/file.serviceAgent IAM role.
    • Enabled the following APIs at the project level:
      • file.googleapis.com
      • gkehub.googleapis.com

        These APIs and permissions are required for filestore provisioning, CSI driver operations, and certificate management within GKE.

Procedure

  1. Perform the following steps to configure DNS and network resources:
    1. Create a host name in Cloud DNS for the DevOps Loop application.
    2. Reserve a global static IPv4 address in the same GCP project.
    3. Create a DNS A record that maps the domain name to the global static IP address.
    For example:
    • Name: <host-name>
    • Type: A
    • Value: <GLOBAL_STATIC_IP>
    Note: DNS must resolve and must be visible from the public internet or at least from GCP checkers for GKE-managed certificate provisioning to succeed.
  2. Perform the following steps to configure RWX StorageClass for DevOps Loop:

    1. Create a custom RWX StorageClass with the following requirements:

      • Minimum 1 TiB storage

      • Provisioner: filestore.csi.storage.gke.io

      • VPC: must match the VPC network used by your GKE cluster

    Note: A custom StorageClass is required so filestore volumes are created within your cluster’s VPC. Otherwise, GCP-provided filestore classes attempt provisioning under the default network.
  3. Verify available StorageClasses by running the following command: 
    kubectl get storageclass

Results

You have prepared the required Google Cloud Platform (GCP) infrastructure for deploying DevOps Loop on Google Kubernetes Engine (GKE).

What to do next

You can now proceed with installing DevOps Loop on GKE.
