Deploy the nginx-ldapauth-proxy helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the `nginx-ldapauth-proxy` Helm Chart on a DigitalOcean Kubernetes Service (DOKS) cluster, we will follow these steps:

1. **Create a DOKS Cluster**: We'll use Pulumi to provision a Kubernetes cluster on DigitalOcean.
2. **Install the Helm Chart**: Once the cluster is provisioned, we'll use Pulumi's Kubernetes provider to install the `nginx-ldapauth-proxy` Helm chart on it.

Below is a Pulumi program in TypeScript that uses the DigitalOcean and Kubernetes packages to accomplish this. Make sure you have Pulumi installed and DigitalOcean access configured before running this program.

The program will:

- Use the `@pulumi/digitalocean` package to create a Kubernetes cluster on DigitalOcean.
- Use the `@pulumi/kubernetes` package to install the `nginx-ldapauth-proxy` Helm chart into the DOKS cluster.

Here's the entire program to achieve this:

```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("do-cluster", {
    region: "nyc3", // Choose the region that is closest to you or your users
    version: "latest", // Use the latest available version of Kubernetes
    nodePool: {
        name: "default",
        size: "s-2vcpu-2gb", // Choose the size that fits your needs
        nodeCount: 2, // Number of nodes to create in the node pool
    },
});

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

// Create a Kubernetes Provider instance using the kubeconfig from the cluster we created
const k8sProvider = new kubernetes.Provider("do-k8s", {
    kubeconfig: cluster.kubeConfigs[0].rawConfig,
});

// Deploy the nginx-ldapauth-proxy Helm chart into the DOKS cluster
const nginxLdapAuthProxyChart = new kubernetes.helm.v3.Chart("nginx-ldapauth-proxy", {
    chart: "nginx-ldapauth-proxy",
    version: "0.1.6",  // Specify the chart version you wish to deploy
    fetchOpts: {
        repo: "https://charts.example.com/", // Replace with the correct Helm repo URL that contains your chart
    },
}, { provider: k8sProvider });

// Export the Helm chart deployment's name
export const helmChartName = nginxLdapAuthProxyChart.ready.map(() => nginxLdapAuthProxyChart.resourceNames.chart);

// Note: The nginx-ldapauth-proxy Helm chart might require you to specify some additional configuration parameters,
// such as details about your LDAP server. You can pass these configuration parameters via the 'values' property
// of the kubernetes.helm.v3.Chart resource above. For exact configuration properties, refer to the chart's documentation.
```

This program will create a new DigitalOcean Kubernetes cluster and install the `nginx-ldapauth-proxy` Helm chart. Make sure to replace the `chart` parameter and `repo` in `fetchOpts` with the correct chart and repository URL where your `nginx-ldapauth-proxy` chart is located.

After you write this code into a `index.ts` file, you can run it using the Pulumi CLI:

```sh
pulumi up
```

This command will execute the deployment, and you'll be prompted to confirm the actions before anything is created.

Remember, when using Helm charts, you often need to provide configuration values specific to your setup. For the `nginx-ldapauth-proxy`, you'll likely need to specify details about your LDAP server and any other necessary options. You can set these values in the Helm chart deployment using the `values` parameter or a separate YAML configuration file. Refer to the Helm chart's documentation for the parameters it requires.
