Deploy the shopware helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the Shopware Helm chart on the Digital Ocean Kubernetes Service using Pulumi, we must complete several steps:
1. Provision a Kubernetes cluster on DigitalOcean.
2. Install the Helm chart for Shopware onto the cluster.

For step 1, we will use the `digitalocean.KubernetesCluster` resource to create a Kubernetes cluster in DigitalOcean. In step 2, we will use the `kubernetes.helm.v3.Chart` resource to deploy the Shopware Helm chart into the Kubernetes cluster.

Here is how you would do this with Pulumi and TypeScript:

First, we need to ensure we have the required Pulumi provider packages installed:

```sh
npm install @pulumi/digitalocean @pulumi/kubernetes
```

Now, here's the TypeScript program that does the job.

```typescript
import * as digitalocean from "@pulumi/digitalocean";
import * as k8s from "@pulumi/kubernetes";

// Step 1: Provision the DigitalOcean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("do-cluster", {
    region: "nyc3",
    version: "latest",
    nodePool: {
        size: "s-2vcpu-2gb",
        nodeCount: 2,
    },
});

// Step 2: Deploy the Shopware Helm chart
const shopwareChart = new k8s.helm.v3.Chart("shopware-chart", {
    chart: "shopware",
    version: "1.2.3", // specify the version of Shopware Helm chart you want to deploy
    fetchOpts: {
        repo: "https://charts.shopware.com/", // Assuming Shopware Helm chart is hosted at this URL
    },
}, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig }) });

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

```

**Explanation of Code Structure:**

- We begin by importing the required Pulumi packages for DigitalOcean and Kubernetes.
- We define a new Kubernetes cluster in the NYC3 region of DigitalOcean with the `digitalocean.KubernetesCluster` resource. The cluster includes a node pool with two nodes of the size `s-2vcpu-2gb`.
- We then instantiate a `k8s.helm.v3.Chart` to deploy the Shopware Helm chart. The `chart` parameter specifies the name of the chart, and `version` specifies which version of the chart to deploy. The `fetchOpts` parameter contains the repository URL.
- We provide a `provider` argument to the chart, creating a Kubernetes provider with the kubeconfig from the newly created cluster. This allows the Helm Chart resource to interact with our DigitalOcean Kubernetes cluster.
- Finally, we export the `kubeconfig` and the `clusterEndpoint` for direct access to the Kubernetes cluster.

Remember, Kubernetes charts might require specific configurations depending on the application's needs, so ensure you adjust the `values` or other chart parameters as needed for Shopware. You may need to review the Helm chart documentation for Shopware to determine the appropriate configurations.

Lastly, after deploying the above Pulumi code, you would use the `pulumi up` command to provision the resources. The output would include the kubeconfig and the endpoint to access your Kubernetes cluster.
