1. Deploy the ohmyform helm chart on Linode Kubernetes Engine


    To deploy the OhMyForm Helm chart on the Linode Kubernetes Engine using Pulumi, you will need to install the Pulumi CLI and set up your Linode credentials in your environment. This will typically involve setting LINODE_TOKEN in your environment variables. After that, you can create a new Pulumi project using your favorite language (here we'll use TypeScript for the example).

    We will go through the following steps:

    1. Set up a new Pulumi project and install necessary dependencies.
    2. Create a new Linode Kubernetes Engine (LKE) cluster.
    3. Deploy the OhMyForm Helm chart to the LKE cluster.

    Below is a program written in TypeScript that uses Pulumi to deploy OhMyForm on Linode.

    First, let's make sure we have Pulumi installed:

    npm install -g pulumi

    Next, set up a new Pulumi project in TypeScript:

    pulumi new typescript

    Now, install the necessary dependencies for our Pulumi program:

    npm install @pulumi/linode @pulumi/kubernetes

    Once the setup is complete, the Pulumi program should look something like this:

    import * as linode from "@pulumi/linode"; import * as k8s from "@pulumi/kubernetes"; // Create a LKE cluster const cluster = new linode.LkeCluster("my-cluster", { label: "my-cluster", k8sVersion: "1.21", region: "us-central", tags: ["pulumi-cluster"], nodePools: [{ type: "g6-standard-2", count: 3, }], }); // Export the Kubeconfig export const kubeconfig = cluster.kubeconfig; // Create a provider for the cluster const provider = new k8s.Provider("my-provider", { kubeconfig: cluster.kubeconfig, }); // Deploy OhMyForm using the Helm Chart const ohMyFormChart = new k8s.helm.v3.Chart("ohmyform", { chart: "ohmyform", version: "1.0.0", // Specify the chart version you want to deploy namespace: "default", fetchOpts: { repo: "https://ohmyform.github.io/helm-charts", // OhMyForm Helm chart repository }, }, { provider }); // Export the OhMyForm service endpoint export const ohMyFormService = ohMyFormChart.getResource("v1/Service", "default/ohmyform");

    Here's an explanation of the code:

    • We first import the required linode and kubernetes packages from Pulumi.
    • We create a new Linode Kubernetes Engine cluster by instantiating linode.LkeCluster. We specify the version of Kubernetes, the region, and the size and count of the nodes in the node pool.
    • We export the kubeconfig of the cluster, which is needed to interact with the Kubernetes API server.
    • Next, we define a Kubernetes Provider with the kubeconfig from the newly created cluster.
    • We then create an instance of k8s.helm.v3.Chart to deploy the OhMyForm Helm Chart from the specified repository. The version of the chart and other parameters can be modified based on the OhMyForm Helm chart's instructions.
    • Finally, we export the service endpoint of OhMyForm, which can be used to access the OhMyForm application once it is deployed.

    Make sure to replace 1.0.0 with the actual version of the OhMyForm Helm Chart you want to use or remove the version attribute to use the latest version.

    To deploy this stack, run:

    pulumi up

    Once the deployment has completed, Pulumi will provide you with the service endpoint for OhMyForm. You can use that URL to access your OhMyForm instance running on Linode Kubernetes Engine.

    Remember to destroy your resources with pulumi destroy if you're done with the example to avoid unnecessary charges.
