Deploy the jitsi helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the Jitsi Helm chart on Digital Ocean Kubernetes Service using Pulumi, we first need to set up a Kubernetes cluster on Digital Ocean. Once the cluster is up and running, we can use the Helm chart to deploy Jitsi Meet onto that cluster.

Here's a step-by-step explanation, followed by the code to accomplish this:

1. **DigitalOcean Kubernetes Cluster**: We'll leverage `digitalocean.KubernetesCluster` from the DigitalOcean Pulumi provider to create a Kubernetes cluster. This will be the environment where Jitsi Meet runs.
   
2. **Helm Chart for Jitsi**: We'll use `kubernetes.helm.v3.Chart` from the Kubernetes Pulumi provider to deploy the Jitsi Meet Helm chart. This Helm chart will install and configure Jitsi Meet on our Kubernetes cluster.

Below is the TypeScript program for deploying a Jitsi Helm chart on Digital Ocean Kubernetes service using Pulumi:

```typescript
import * as digitalocean from "@pulumi/digitalocean";
import * as kubernetes from "@pulumi/kubernetes";
import * as pulumi from "@pulumi/pulumi";

// Create a DigitalOcean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("jitsi-cluster", {
    region: digitalocean.Regions.NYC1,
    version: "latest",
    nodePool: {
        size: digitalocean.DropletSlugs.DropletS2VCPU2GB,
        name: "worker-pool",
        nodeCount: 2,
    },
});

// Get the kubeconfig for the created cluster
const kubeconfig = pulumi
    .all([cluster.name, cluster.kubeConfigs])
    .apply(([name, kubeConfigs]) => kubeConfigs[0].rawConfig);

// Create a Kubernetes provider instance using the kubeconfig from the DigitalOcean cluster
const k8sProvider = new kubernetes.Provider("k8s-provider", {
    kubeconfig: kubeconfig,
});

// Deploy Jitsi using a Helm chart
const jitsiChart = new kubernetes.helm.v3.Chart(
    "jitsi",
    {
        chart: "jitsi", // You may need to change this if the chart name in your Helm repo is different
        version: "1.1.0", // Pick the version of the Helm chart to use
        namespace: "jitsi-meet",
        fetchOpts:{
            repo: "https://jitsi.github.io/helm/",
        },
    },
    { provider: k8sProvider }
);

// Export the Kubeconfig and Jitsi service endpoint
export const kubeConfigOutput = kubeconfig;
export const jitsiServiceEndpoint = jitsiChart.getResourceProperty("v1/Service", "jitsi-web", "status")
    .apply(status => status.loadBalancer.ingress[0].ip || status.loadBalancer.ingress[0].hostname);
```

This program creates a Kubernetes cluster in the DigitalOcean NYC1 region using two 2vCPU/2GB Droplets. It then retrieves the `kubeconfig`, which is needed to communicate with the Kubernetes cluster from your machine.

The `kubernetes.Provider` is then instantiated with this `kubeconfig`, which allows Pulumi to deploy resources into the new Digital Ocean Kubernetes cluster.

Next, we deploy the Jitsi Helm chart into a namespace named `jitsi-meet` in our cluster. The `repo` field within `fetchOpts` specifies the Helm repository where the Jitsi Helm chart can be found.

Finally, we export the kubeconfig and the service endpoint of the Jitsi web interface, so you can interact with the cluster and the Jitsi instance.

To use this Pulumi program, simply place it in a TypeScript file in a Pulumi project. Configure your Pulumi and DigitalOcean credentials (typically using the `pulumi config set` command to set your DigitalOcean access token). Then, run `pulumi up` to deploy the resources.
