1. Deploy the akash-node helm chart on Digital Ocean Kubernetes Service


    To deploy an Akash node Helm chart on the Digital Ocean Kubernetes service using Pulumi, you will first need to create a Kubernetes cluster on Digital Ocean, and then deploy the Akash node Helm chart on the cluster.

    Here's a step-by-step guide and the Pulumi TypeScript program to accomplish this task:

    1. Set up the Digital Ocean Kubernetes Cluster:

      • Using the digitalocean.KubernetesCluster resource, we create a Kubernetes cluster on Digital Ocean. You need to specify the region, version of Kubernetes to use, and details for the node pool including the size (which denotes the type of machine to use) and the number of nodes.
    2. Deploy the Akash Node Helm Chart:

      • Using the kubernetes.helm.v3.Chart resource, you can deploy the Helm chart to the Kubernetes cluster. You'll need to specify the name of the chart, any custom values you want to override in the chart's values.yaml file, and the namespace you'd like to deploy to. If the Helm chart is hosted on a private repository, you will need to provide the repository URL as well.

    Below is the TypeScript program to perform these tasks. Make sure you have the Pulumi CLI installed and configured to use your Digital Ocean token. You will also need kubectl configured to interact with Digital Ocean's Kubernetes API.

    import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; import * as kubernetes from '@pulumi/kubernetes'; // Create a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster('do-cluster', { region: 'nyc1', version: 'latest', // Or specify your preferred version nodePool: { name: 'default', size: 's-2vcpu-2gb', // This is the smallest size available; choose based on your needs nodeCount: 1, // Modify based on how many nodes you want in your cluster }, }); // Export the Kubeconfig so we can interact with the cluster export const kubeConfig = cluster.kubeConfigs[0].rawConfig; // Create a provider for the Kubernetes cluster created so Helm can deploy to it const k8sProvider = new kubernetes.Provider('do-k8s', { kubeconfig: kubeConfig, }); // Deploy the Akash node Helm chart to the Digital Ocean Kubernetes cluster const akashNodeChart = new kubernetes.helm.v3.Chart('akash-node', { chart: 'akash-node', // Name of the Helm chart for Akash node version: '0.1.0', // Specify the chart version if necessary // Add any custom value overrides here if you need to configure Akash node differently values: { // Example override (these values are placeholders, replace them with real ones): // persistence: { // size: '10Gi', // }, }, }, { provider: k8sProvider }); // Export the endpoint to access the Akash node export const akashNodeEndpoint = pulumi.interpolate`http://${akashNodeChart.getResourceProperty("v1/Service", "akash-node-akash-node", "status")["loadBalancer"]["ingress"][0]["ip"]}`;

    This program sets up a Kubernetes cluster and deploys the Akash node Helm chart to it. Make sure to replace placeholders with actual values that suits your use case.


    • The kubeconfig: kubeConfig, in the Provider setup allows us to use the output of the Kubernetes cluster as the configuration for the Helm chart.
    • You may need to wait a few minutes after running pulumi up before the cluster is available to deploy Helm charts to it.
    • The persistence.size override is just an example. You would need to put actual values in the values object that are needed for the Akash node.
    • Be careful about the cluster size and nodeCount; creating large clusters can be costly.
    • The exported akashNodeEndpoint gives you the endpoint address to access your Akash node once it is deployed. Remember, it may take a few minutes for the external IP to be assigned.
