1. Deploy the jx-app-anchore helm chart on Google Kubernetes Engine (GKE)


    To deploy the jx-app-anchore Helm chart on Google Kubernetes Engine (GKE), we will follow these steps:

    1. Create a GKE Cluster: We'll start by defining a GKE cluster resource using Pulumi's google-native.container.v1beta1.Cluster resource. This represents a Kubernetes cluster on GCP.

    2. Configure Kubeconfig: After creating the cluster, we'll obtain the kubeconfig file that allows us to interact with the cluster using kubectl and other Kubernetes tools.

    3. Deploy Helm Chart: Finally, we'll use Pulumi's kubernetes.helm.v3.Chart resource to deploy the jx-app-anchore Helm chart to our GKE cluster.

    Below is the TypeScript program that accomplishes this task:

    import * as gcp from '@pulumi/gcp'; import * as k8s from '@pulumi/kubernetes'; import * as pulumi from '@pulumi/pulumi'; // Step 1: Create a GKE cluster const cluster = new gcp.container.Cluster('gke-cluster', { initialNodeCount: 1, minMasterVersion: 'latest', nodeVersion: 'latest', nodeConfig: { machineType: 'n1-standard-1', oauthScopes: [ "https://www.googleapis.com/auth/compute", "https://www.googleapis.com/auth/devstorage.read_only", "https://www.googleapis.com/auth/logging.write", "https://www.googleapis.com/auth/monitoring" ], }, }); // Export the Cluster name export const clusterName = cluster.name; // Step 2: Configure Kubeconfig const kubeconfig = pulumi. all([ cluster.name, cluster.endpoint, cluster.masterAuth ]). apply(([ name, endpoint, masterAuth ]) => { const context = `${gcp.config.project}_${gcp.config.zone}_${name}`; return `apiVersion: v1 clusters: - cluster: certificate-authority-data: ${masterAuth.clusterCaCertificate} server: https://${endpoint} name: ${context} contexts: - context: cluster: ${context} user: ${context} name: ${context} current-context: ${context} kind: Config preferences: {} users: - name: ${context} user: auth-provider: config: cmd-args: config config-helper --format=json cmd-path: gcloud expiry-key: '{.credential.token_expiry}' token-key: '{.credential.access_token}' name: gcp `; }); // Export the Kubeconfig export const kubeConfig = kubeconfig; // Step 3: Deploy jx-app-anchore Helm chart const jxAppAnchore = new k8s.helm.v3.Chart('jx-app-anchore', { chart: 'jx-app-anchore', version: '0.0.1', // Specify the version of the Helm chart you want to deploy fetchOpts:{ repo: 'https://charts.jenkins-x.io', // Specify the Helm chart repository }, }, { provider: new k8s.Provider('k8s-provider', {kubeconfig}) }); // Export the Helm chart name export const helmChartName = jxAppAnchore.chart;

    This program does the following:

    • Defines a GKE cluster with the required node configuration, including machine type and OAuth scopes.
    • Exports the cluster name, which is generated by Pulumi and is needed to interact with the cluster.
    • Generates a kubeconfig file that allows you to connect to the GKE cluster using the Kubernetes CLI kubectl.
    • Exports this kubeconfig so you can easily set your KUBECONFIG environment variable to this output for kubectl use.
    • Deploys a specific version of the jx-app-anchore Helm chart from the Jenkins X chart repository to the GKE cluster.
    • Utilizes the generated kubeconfig to create an instance of the Pulumi Kubernetes provider to interact with the GKE cluster.
    • Exports the name of the deployed Helm chart.

    To run this Pulumi program, you need to have Pulumi installed and configured with your GCP credentials. You would place this code in a file (e.g., index.ts), run pulumi up, and Pulumi will perform the necessary steps to provision the resources and deploy the Helm chart on GKE.
