1. Deploy the servicemesh-kiali-resource helm chart on Google Kubernetes Engine (GKE)


    To deploy a Helm chart for a service mesh with Kiali on Google Kubernetes Engine (GKE), we'll need to perform a series of steps using Pulumi. Before we start, you need a GCP account and a Pulumi account. You also need to have Pulumi CLI installed and configured for use with your chosen programming language and cloud provider.

    Here's what the program will do:

    1. Create a GKE cluster where our Helm chart will be deployed.
    2. Install and configure the Helm provider to manage Helm releases on this Kubernetes cluster.
    3. Define a Helm release for the servicemesh-kiali-resource or an equivalent, including necessary configurations.

    Below is the TypeScript program which demonstrates these steps:

    import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create a GKE cluster const cluster = new gcp.container.Cluster("my-gke-cluster", { initialNodeCount: 2, nodeVersion: "latest", minMasterVersion: "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; // Export the Kubeconfig so Pulumi can connect to the cluster 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 `; }); // Create a Kubernetes Provider referencing the new Kubeconfig const k8sProvider = new k8s.Provider("gkeK8s", { kubeconfig: kubeconfig, }); // Install the Helm chart for the service mesh with Kiali on the GKE cluster // Refer to the Helm chart repository for `servicemesh-kiali-resource` for its config values const kialiRelease = new k8s.helm.v3.Release("kiali", { chart: "kiali", version: "1.29.0", // Specify the chart version you want to deploy repositoryOpts: { repo: "https://kiali.org/helm-charts", // Use the correct Helm repository URL }, namespace: "istio-system", // Deploy Kiali in the Istio system namespace values: { // Set the values for the Kiali Helm chart as required }, }, { provider: k8sProvider }); // Export the Helm release name export const kialiReleaseName = kialiRelease.name;

    Here's an explanation for each part of the program:

    1. Import the required Pulumi packages: The @pulumi/gcp, @pulumi/kubernetes, and @pulumi/pulumi packages are imported to be used within the program. These packages allow us to define resources related to GCP and Kubernetes.

    2. Create a GKE cluster: We define a GKE cluster with a specified number of nodes, node version, and the necessary OAuth scopes for the nodes to interact with other GCP services. The machineType is set to n1-standard-1, which can be adjusted according to your needs.

    3. Export the cluster name: The name of the GKE cluster is exported so that it can be easily accessed after the deployment.

    4. Generate and export Kubeconfig: This configuration file enables Pulumi to connect and interact with the Kubernetes cluster. It uses the cluster details and GCP authentication provider.

    5. Create a Kubernetes Provider instance: This provider uses the generated Kubeconfig, allowing Pulumi to manage Kubernetes resources on the GKE cluster.

    6. Install the Helm chart: We define a Helm release using Pulumi's Kubernetes provider. This references the Kiali Helm chart and its specific version, along with the Helm repository that contains the chart. The namespace and values fields should be specified based on how you want to configure Kiali and your service mesh.

    Remember to replace "servicemesh-kiali-resource" with the actual chart name if it's different, and ensure that you are using the correct chart version and repository URL. For the values, provide the configuration according to the Helm chart's documentation.

    After this Pulumi program is executed, it will:

    • Create a GKE cluster.
    • Configure kubectl using the outputted Kubeconfig.
    • Deploy the specified Helm chart onto the GKE cluster.

    Please remember to replace dummy values like chart, version, repositoryOpts.repo, and values in the chart deployment with the actual values specific to the Kiali Helm chart you intend to deploy.
