1. Deploy the floriapp-mongodb helm chart on Linode Kubernetes Engine

    TypeScript

    To deploy the floriapp-mongodb Helm chart on Linode Kubernetes Engine (LKE) using Pulumi, you'll need to follow multiple steps. First, you'll need to create an LKE cluster if you don't already have one. Then, you'll install the Helm chart into the LKE cluster.

    We are going to use the @pulumi/kubernetes package, which allows us to interact with Kubernetes clusters, including deploying Helm charts. Here are the steps in the program:

    1. Create a new LKE cluster or use an existing one.
    2. Use the Kubernetes provider to interact with the LKE cluster.
    3. Deploy the floriapp-mongodb Helm chart using the Chart resource.

    Below is a Pulumi program written in TypeScript that accomplishes these tasks:

    import * as k8s from "@pulumi/kubernetes"; import * as linode from "@pulumi/linode"; // Step 1: Create an LKE cluster (or you can use an existing one) const cluster = new linode.LkeCluster("my-lke-cluster", { region: "us-central", k8sVersion: "1.20", label: "my-cluster", tags: ["pulumi-lke"], pools: [{ type: "g6-standard-1", count: 1, }], }); // Step 2: Create a Kubernetes Provider pointing to the kubeconfig of the LKE cluster const kubeconfig = cluster.kubeconfig.apply(JSON.parse); const provider = new k8s.Provider("my-lke-provider", { kubeconfig: kubeconfig.rawConfig, }); // Step 3: Deploy the floriapp-mongodb Helm chart into the LKE cluster const mongodbChart = new k8s.helm.v3.Chart("mongodb-chart", { chart: "mongodb", // If the helm chart is hosted in a helm repository, you need to provide the `repo` option. // For the purpose of this example, I'm assuming the mongodb chart is available in the default repos. // repo: "Specify the repo URL here if necessary", version: "Enter the chart version here if needed", namespace: "default", // Make sure to input the correct values for the chart according to the floriapp-mongodb Helm chart's requirements values: { // Example: Specify the required chart values here // replicaCount: 1, // image: { repository: "mongo", tag: "latest" }, // ... }, }, { provider: provider }); // Export the cluster's kubeconfig and MongoDB service endpoint export const kubeConfigRaw = kubeconfig.rawConfig; export const mongodbServiceEndpoint = mongodbChart.getResourceProperty("v1/Service", "mongodb-chart-mongodb", "status").apply(status => status.loadBalancer.ingress[0].ip);

    When you run this Pulumi program, it will do the following:

    • Create an LKE cluster: This cluster is tagged with "pulumi-lke" and has a single node pool with one node of type "g6-standard-1".
    • Create a Kubernetes Provider: This provider uses the kubeconfig from the newly created Linode Kubernetes Engine (LKE) cluster to manage resources.
    • Deploy the Helm chart: We create a Helm chart resource, specifying the chart name as "mongodb" which is a placeholder for the floriapp-mongodb chart you mentioned. You should adjust the chart, version, values, and potentially the repo field to match the specifics of the floriapp-mongodb Helm chart.

    Finally, the program exports the raw kubeconfig needed to interact with the cluster and an endpoint for the MongoDB service assuming it creates a LoadBalancer service that gets an external IP address assigned.

    Remember to replace placeholders like Enter the chart version here if needed with actual values appropriate for the Helm chart you wish to deploy. Adjust the values option in the mongodbChart to set the necessary settings for the floriapp-mongodb Helm chart.

    Assuming you have Pulumi CLI set up and the Linode provider configured, you can run this program using the following steps:

    1. Save the above TypeScript code to a file named index.ts.
    2. Run pulumi stack init to create a new stack.
    3. Run pulumi up to preview and deploy the changes.

    After confirming the changes, Pulumi will deploy the Helm chart to the LKE cluster and will output the kubeconfig and the MongoDB service endpoint.
