How Do I Deploy the KeyDB Helm Chart on Digital Ocean Kubernetes Service?

Introduction

This guide provides a comprehensive walkthrough on deploying the KeyDB Helm chart on a Digital Ocean Kubernetes Service (DOKS) using Pulumi. The purpose is to set up a Kubernetes cluster on Digital Ocean and utilize the Pulumi Kubernetes provider for managing and deploying the KeyDB Helm chart effectively.

Step-by-Step Explanation

Step 1: Create a Kubernetes Cluster on Digital Ocean

Begin by setting up a Kubernetes cluster on Digital Ocean. This involves specifying the cluster’s region, version, and node pool configuration.

import * as digitalocean from "@pulumi/digitalocean";

const cluster = new digitalocean.KubernetesCluster("my-cluster", {
    region: digitalocean.Region.NYC3,
    version: "1.21.5-do.0",
    nodePool: {
        name: "default",
        size: digitalocean.DropletSlug.DropletS2VCPU2GB,
        nodeCount: 3,
    },
});

Step 2: Export the Kubeconfig

Once the cluster is created, export the Kubeconfig to interact with the cluster.

export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

Step 3: Create a Kubernetes Provider Instance

Utilize the exported Kubeconfig to create a Kubernetes provider instance. This allows for managing resources on the cluster.

import * as k8s from "@pulumi/kubernetes";

const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: kubeconfig,
});

Step 4: Deploy the KeyDB Helm Chart

Finally, deploy the KeyDB Helm chart using the Pulumi Kubernetes provider. This involves specifying the chart details and repository.

const keydb = new k8s.helm.v3.Chart("keydb", {
    chart: "keydb",
    version: "0.1.0",
    fetchOpts: {
        repo: "https://charts.bitnami.com/bitnami",
    },
}, { provider: k8sProvider });

Conclusion

In summary, this guide detailed the process of deploying the KeyDB Helm chart on a Digital Ocean Kubernetes Service using Pulumi. We covered creating a Kubernetes cluster, exporting the Kubeconfig, setting up a Kubernetes provider, and deploying the Helm chart. This setup ensures efficient management and deployment of KeyDB on a Digital Ocean Kubernetes cluster.
