Kubernetes Workload in GKE

This page shows how to deploy a Kubernetes workload on Google Kubernetes Engine (GKE) using the Fractal SDK.

For prerequisites, setup, and deployment file structure, see the main guide.

Java SDK

public static GoogleKubernetesEngine getGke(String id) {
  return GoogleKubernetesEngine.builder()
    .withId(id)
    .withRegion(EU_WEST1)
    .withNodePools(getNodePools())
    .withK8sWorkload(getK8sWorkload())
    .build();
}

public static CaaSKubernetesWorkload getK8sWorkload() {
  return CaaSKubernetesWorkload.builder()
    .withId("fractal-samples")
    .withDescription("Fractal Service on K8S")
    .withNamespace("fractal")
    .withSSHRepositoryURI("git@github.com:YanchWare/fractal-samples.git")
    .withRepoId("YanchWare/fractal-samples")
    .withBranchName("env/prod")
    .withEnvironmentSecretShortName("my-secret-name") // Add secret access
    // Optional: Use a specific CI/CD profile
    //.withCiCdProfileShortName("my-other-cicd-profile")
    .build();
}

public static Collection<? extends GcpNodePool> getNodePools() {
  return List.of(
    GcpNodePool.builder()
      .withName("nodes")
      .withMachineType(E2_STANDARD2)
      .build()
  );
}

TypeScript SDK

import { GcpGkeCluster, LiveSystem } from '@fractal_cloud/sdk';

const gkeCluster = GcpGkeCluster.getBuilder()
  .withId('my-gke-cluster')
  .withVersion(1, 0, 0)
  .withDisplayName('GKE with Custom Workload')
  .withKubernetesVersion('1.28.5')
  .withNetworkPolicyProvider('calico')
  .withNodePools([
    {
      name: 'nodes',
      machineType: 'e2-standard-2',
      initialNodeCount: 1,
    },
  ])
  .withWorkloadIdentityEnabled(true)
  .build();
