Deploy the xos-gui helm chart on Digital Ocean Kubernetes Service

To deploy the xos-gui Helm chart on the Digital Ocean Kubernetes Service (DOKS), you can follow these steps:

1. Create a Kubernetes Cluster on DigitalOcean: We'll use the digitalocean.KubernetesCluster resource to set up the cluster, specify the region, version, and node pool configuration. Remember to replace 'your-cluster-name' and 'your-nodepool-name' with the names you want for your cluster and node pool, respectively.

2. Deploy the xos-gui Helm Chart: After the cluster is set up, we'll use the kubernetes.helm.v3.Chart resource to deploy the Helm chart for xos-gui.

Firstly, ensure that you have Pulumi installed and set up with DigitalOcean by having an access token configured. You can create one from the DigitalOcean control panel and then set it with the pulumi config set digitalocean:token [YOUR_TOKEN] --secret command.

Here's a Pulumi TypeScript program that you can use as a starting point:

import * as pulumi from '@pulumi/pulumi';
import * as digitalocean from '@pulumi/digitalocean';
import * as k8s from '@pulumi/kubernetes';

// Create a DigitalOcean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster('xos-gui-cluster', {
    region: 'nyc1',
    version: 'latest', // specify the desired Kubernetes version
    nodePool: {
        name: 'default',
        size: 's-2vcpu-2gb', // specify the size of the node
        nodeCount: 2, // specify the number of nodes in the node pool
    },
});

// Create a k8s Provider instance using the kubeconfig from the DigitalOcean cluster
const k8sProvider = new k8s.Provider('do-k8s-provider', {
    kubeconfig: cluster.kubeConfigs[0].rawConfig,
});

// Deploy xos-gui Helm chart on the cluster using the k8s provider
const xosGuiChart = new k8s.helm.v3.Chart('xos-gui-chart', {
    chart: 'xos-gui',
    // Assuming 'xos-gui' is publicly available in a Helm repository
    // If it's not, you might need to specify the 'repo' property with the URL of the Helm repo
    namespace: 'default', // replace with the namespace you want to deploy into, if not 'default'
    // Specify any custom values needed for the xos-gui chart
    values: {
        // ...custom values
    },
}, { provider: k8sProvider });

// Export the Kubernetes cluster name
export const clusterName = cluster.name;

// Export the Helm chart deployment status
export const xosGuiStatus = xosGuiChart.status;

Explanation

• DigitalOcean Kubernetes Cluster: The digitalocean.KubernetesCluster resource defined in the program creates a new managed Kubernetes cluster in the specified region with the desired version and node pool configuration.

  • Kubernetes Version: Set to 'latest' to use the latest Kubernetes version supported by DigitalOcean at the time of cluster creation.

  • Node Pool: This configuration defines the size and number of nodes for the cluster's default node pool.

• Kubernetes Provider: Before deploying the Helm chart, we instantiate a Pulumi Kubernetes provider bound to the newly created DOKS cluster by passing its kubeconfig. This provider is then used to deploy resources to the cluster.

• Helm Chart: We deploy the xos-gui Helm chart using the k8s.helm.v3.Chart resource, which requires the chart name and optionally the URL of the Helm repository if it's not publicly available in the regular Helm chart repositories.

• Exports: At the end, there are two exported values. The clusterName exports the name of the DigitalOcean Kubernetes cluster, and the xosGuiStatus exports the deployment status of the Helm chart, which can be used to check if the deployment was successful.

When you execute this Pulumi program by running pulumi up in the same directory as the file, it will prompt you to create the resources described above. Once executed, it will create a DigitalOcean Kubernetes cluster and deploy the xos-gui Helm chart on it.

Ensure that you have configured Pulumi to use your DigitalOcean access token, and you've set the DIGITALOCEAN_ACCESS_TOKEN environment variable or used the Pulumi config to securely store your token.
