1. Deploy the redis-cache helm chart on Digital Ocean Kubernetes Service


    To deploy the redis-cache Helm chart on a Digital Ocean Kubernetes Service using Pulumi, you'll need to perform the following steps:

    1. Set up a DigitalOcean Kubernetes Cluster: You'll first need to create a Kubernetes cluster in DigitalOcean.
    2. Install the Redis Cache Helm chart: After setting up the cluster, use the Helm package manager to install the redis-cache chart.

    I'll guide you through the process with a Pulumi program written in TypeScript.

    Step 1 - Configure the Pulumi Kubernetes Provider for DigitalOcean

    Before you can deploy applications on your Kubernetes cluster, you need to configure the Pulumi Kubernetes provider to use the credentials for your DigitalOcean Kubernetes cluster. Pulumi uses these credentials to authenticate with your cluster and manage resources.

    Step 2 - Deploy the Redis Cache Helm Chart

    We'll use Pulumi's Kubernetes provider to deploy the Helm chart. For the Helm chart, we'll refer to a known repository that hosts the redis chart such as Bitnami which often provides the redis chart that could be used as a redis-cache. We'll assume there's a chart named redis-cache for this deployment.

    Below is the Pulumi program written in TypeScript that performs these steps. The comments in the code will guide you through what each section does:

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc1", version: "latest", // or specify your desired version nodePool: { name: "default", size: "s-1vcpu-2gb", // choose the node size that fits your needs nodeCount: 2, // number of nodes in the node pool }, }); // Step 2: Deploy the redis-cache Helm chart on the cluster const redisCacheChart = new k8s.helm.v3.Chart("redis-cache", { chart: "redis", version: "10.5.7", // choose a version of the Helm chart fetchOpts: { repo: "https://charts.bitnami.com/bitnami", }, values: { // Customize the Helm chart values here, or leave it empty to use default values // Example: // usePassword: false }, }, { provider: new k8s.Provider("do-k8s", { kubeconfig: cluster.kubeConfigs[0].rawConfig }) }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Export the Redis service endpoint export const redisHost = redisCacheChart.getResourceProperty("v1/Service", "redis-cache-master", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Note: The provided values for the Helm chart are for illustrative purposes. Adjust them according to the actual redis-cache chart's values.

    How to Run the Program

    Save the above script to a file, such as index.ts. Then, use the following Pulumi CLI commands from the same directory:

    • Run pulumi up to preview and deploy the changes. Confirm the deployment when prompted to create the DigitalOcean Kubernetes cluster and install the redis-cache Helm chart.
    • Run pulumi stack output kubeconfig to retrieve the kubeconfig for your newly created Kubernetes cluster.
    • Run pulumi stack output redisHost to retrieve the Redis service endpoint once the deployment is complete.

    Make sure you have already setup Pulumi and have the appropriate DigitalOcean authentication configured for Pulumi to interact with your DigitalOcean account.

    Congratulations! You've successfully deployed the redis-cache Helm chart on a DigitalOcean Kubernetes cluster using Pulumi.
