gke-fleet-examples

This project contains easy-to-follow examples for managing multiple Google Kubernetes Engine (GKE) clusters via GKE fleets.

Contents

1. fleet-and-teams-setup: Contains a Terraform configuration for provisioning a fleet encompassing three clusters and two teams. This serves as a straightforward Terraform implementation of fleet team management.

2. config-management/configs: A repository demonstrating the use of Anthos Config Management to sync configurations to team namespaces in clusters across the fleet established in the "fleet-and-teams-setup" directory.

3. fleet-and-argocd: Contains an example using Argo CD to deploy applications to Fleet team namespaces.

   • The fleet has three application clusters on GKE, one app operator team frontend with a webserver namespace.

     

   • Platform admin intalls an argocd-fleet-syncer in the Argo CD central cluster. This tool will poll your fleet clusters and teams' tenancy topoloy, and creates Argo CD cluster secrets labeled with the teams.

   • Platform admins deploys a webserver-applicationset in the Argo CD central cluster. The ApplicationSet specifies a Git repo path as the source of the CD pipeline, and Fleet team frontend's webserver namespace as the destination. Then the CD pipeline is ready!

   • The frontend app operator team can now create deployments and configurations in the source Git repo path. They will be automatically synced into the webserver Fleet namespace.
