1. Deploy the openwhisk helm chart on Linode Kubernetes Engine


    To deploy the OpenWhisk Helm chart on Linode Kubernetes Engine, you'll need to perform the following steps:

    1. Set up a new Linode Kubernetes Engine (LKE) cluster or use an existing one.
    2. Install the Helm CLI on your local machine.
    3. Add the necessary Helm repositories for OpenWhisk.
    4. Define the values for the OpenWhisk Helm chart according to your requirements.
    5. Deploy OpenWhisk on your LKE cluster using the Helm chart.

    Below is a Pulumi program in TypeScript that demonstrates how to set up the OpenWhisk Helm chart on an LKE cluster. This program assumes you have already set up Pulumi with the necessary Linode and Helm providers.

    We will use the kubernetes.helm.v3.Chart class from Pulumi's Kubernetes provider to deploy OpenWhisk using its Helm chart. This class represents a Helm chart in Pulumi, and it allows you to manage the lifecycle of a chart using Pulumi's infrastructure as code methodology.

    Here's the full program, which you can run to deploy the OpenWhisk Helm chart on LKE:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; import * as linode from "@pulumi/linode"; // Step 1: Create a new LKE cluster or use an existing one. // Here, we create a new LKE cluster for this example. const cluster = new linode.LkeCluster("my-lke-cluster", { k8sVersion: "1.20", region: "us-central", nodePools: [{ type: "g6-standard-1", count: 3 }] }); // Step 2: Set up the Kubernetes provider to connect to the LKE cluster. // The kubeconfig is obtained from the LKE cluster object. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig, }); // Step 3: Deploy the OpenWhisk Helm chart using the kubernetes.helm.v3.Chart class. const openwhiskChart = new k8s.helm.v3.Chart("openwhisk", { // Replace this with the correct chart and repo URL for OpenWhisk chart: "openwhisk", version: "1.0", // specify the version of the chart you want to deploy fetchOpts: { repo: "https://openwhisk.apache.org/charts" }, // Define any custom values you want to pass to the Helm chart. values: { whisk: { ingress: { type: "NodePort", apiHostName: cluster.endpoint, apiHostPort: 31001, }, persistence: { haStorageClass: "do-block-storage", storageClassName: "do-block-storage", // ... more custom values ... }, }, // ... more custom values ... }, }, { provider: k8sProvider }); // Step 4: Export the endpoint to access OpenWhisk API. export const openwhiskApiEndpoint = pulumi.interpolate`http://${cluster.endpoint}:31001`; // After the deployment, you can access the OpenWhisk API using the exported endpoint.

    To run this Pulumi program, you would:

    • Install Pulumi on your machine.
    • Set up the Linode and Kubernetes configuration using Pulumi CLI.
    • Save the above code in a file named index.ts.
    • Run pulumi up to deploy your infrastructure.

    Remember, before running this program, ensure you've configured Pulumi with the appropriate Linode credentials and have access to your Linode Kubernetes Engine. The above export provides an endpoint for the OpenWhisk API. However, depending on the OpenWhisk Helm chart configuration, the exact values and structure might change, so make sure to consult the OpenWhisk Helm chart's documentation for precise configuration options.
