Cluster configuration samples

This document provides YAML samples of the most common Google Distributed Cloud cluster configurations. The sample cluster configuration files provide permutations of the following features and capabilities:

How to use the samples

This collection of YAML samples is intended primarily as an educational reference that illustrates how various features look when properly configured. If you want to use these samples to create your own clusters, you need to make changes. Many of the values used, such as the values for the storage section, are defaults and work for most clusters. However, other values, such as spec.authentication.oidc.clientID and spec.gkeConnect.projectID, are specific to your project and environment.

Familiarize yourself with the related feature documentation before attempting to use any of the YAML content provided in this document.

Standalone clusters

Note the following capabilities of a standalone cluster:

  • It can administer itself
  • It can run workloads
  • It can't create or manage other/user clusters

Standalone clusters are suited for cluster installations that require a small footprint or in situations where you want to run clusters in network-isolated partitions.

For more information about standalone clusters, see Standalone cluster deployment and Create standalone clusters.

Basic edge profile

Note the following features and options in this standalone cluster configuration:

  • Single node
  • Edge profile
  • No node pools

Hybrid clusters

Note the following capabilities of a hybrid cluster:

  • It can administer itself
  • It can run workloads
  • It can manage other user clusters

Hybrid clusters function like admin clusters that can run user workloads. Just like admin clusters, hybrid clusters can manage other user clusters. For more information about standalone clusters, see Hybrid cluster deployment and Create hybrid clusters.

Admin clusters

An admin cluster is used to manage other user clusters. Use admin clusters if you have a fleet of clusters in the same data center that you want to manage from a centralized place, and for larger deployments that need isolation between different teams or between development and production workloads.

For more information about admin clusters, see Multi-cluster deployment and Create admin clusters.

User clusters

A user cluster runs your containerized workloads. User clusters must contain one or more worker nodes that run user workloads. Use user clusters if you have a fleet of clusters in the same data center that you want to manage from a centralized place. User clusters are also recommended for larger deployments that need isolation between different teams or between development and production workloads.

For more information about admin clusters, see Multi-cluster deployment and Create user clusters.
