Deploy the atlassian-confluence helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the Atlassian Confluence Helm chart on DigitalOcean's Kubernetes Service using Pulumi, we'll follow these steps:

1. **Set up the DigitalOcean Kubernetes Cluster**: We'll create a Kubernetes cluster in your specified region with the desired node size and count.
2. **Deploy the Helm Chart**: Once the cluster is provisioned, we'll deploy the Atlassian Confluence Helm chart into the cluster.

For this task, we'll use two Pulumi resources from the DigitalOcean and Kubernetes packages:

- `digitalocean.KubernetesCluster`: Creates a new Kubernetes cluster managed by DigitalOcean.
- `kubernetes.helm.v3.Chart`: Represents a Helm chart for deploying software stacks in a Kubernetes cluster.

Here's a Pulumi program that accomplishes this:

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

// Step 1: Create a DigitalOcean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("do-cluster", {
    region: "nyc1",                                     // Replace with the region you want your cluster in
    version: "latest",                                  // Use the latest available version of Kubernetes
    nodePool: {
        name: "worker-pool",
        size: "s-2vcpu-2gb",                           // Choose the size of the nodes
        nodeCount: 2,                                   // Set the number of nodes you want
    },
});

// Step 2: Deploy the Atlassian Confluence Helm chart
const confluenceChart = new kubernetes.helm.v3.Chart("confluence", {
    chart: "atlassian-confluence",
    // Specify the repo where the chart can be found
    fetchOpts: {
        repo: "https://atlassian.github.io/data-center-helm-charts", // This URL will need to be updated if Atlassian moves their Helm repo
    },
    // If needed, you can specify the values for your confluence deployment
    // values: {
    //     'key': 'value',
    // },
}, { provider: new kubernetes.Provider("k8s-provider", {kubeconfig: cluster.kubeConfigs[0].rawConfig}) });

// Export the DigitalOcean Kubernetes cluster's kubeconfig and endpoint
export const kubeconfig = cluster.kubeConfigs[0].rawConfig;
export const clusterEndpoint = cluster.endpoint;
```

In the code above:

- We first create a new Kubernetes cluster on DigitalOcean by instantiating a `digitalocean.KubernetesCluster` object with the desired specifications.
- Next, we deploy the Confluence Helm chart using a `kubernetes.helm.v3.Chart` object. We set the `chart` field to the name of the Confluence chart and the `fetchOpts.repo` to the URL where the Helm chart repository is hosted by Atlassian.

Please replace placeholders like the region, node size, and values for the Confluence Helm chart with your preferred configuration. Ensure that you check the availability of regions and node sizes in the DigitalOcean documentation and the specific values that the Confluence Helm chart accepts.

Remember to install Pulumi and configure it with your DigitalOcean access token before running this program. Once it's set up, you can run `pulumi up` in the same directory as the code to provision your cluster and deploy Confluence. After the deployment is complete, you can access your Confluence instance using the load balancer IP or DNS created by Helm on your Kubernetes cluster.

Please note that the URL provided for the Atlassian Helm charts is based on their current hosting location; you should verify this URL when you run the program. If Atlassian has moved their Helm repository, you'll need to update the `fetchOpts.repo` field accordingly.
