1. Deploy the ckan helm chart on Digital Ocean Kubernetes Service


    To deploy the CKAN helm chart on Digital Ocean Kubernetes Service (DOKS), we will perform the following steps:

    1. Create a Kubernetes cluster on Digital Ocean.
    2. Deploy the CKAN Helm chart to that Kubernetes cluster.

    We'll create a Pulumi program in TypeScript to accomplish these tasks. This program will use the @pulumi/digitalocean package to create the Kubernetes cluster and the @pulumi/kubernetes package to deploy the Helm chart.

    Below is an explanation of what each part of the program is doing:

    • We start by importing the necessary Pulumi packages.
    • Next, we create a Kubernetes cluster in Digital Ocean by specifying the desired configuration, such as region, the size of the nodes, and the number of nodes in the default node pool.
    • After the cluster is ready, we use the pulumi/kubernetes provider to connect to the cluster.
    • Finally, we deploy the CKAN Helm chart using the Helm chart resource. We specify the name of the chart, the repository where it's located, and any custom values we want to apply to our deployment.

    Please make sure you have Pulumi installed, and your Digital Ocean and Kubernetes configuration set. Pulumi uses the configuration to authenticate requests to Digital Ocean.

    Here's the TypeScript program:

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Create a Digital Ocean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("ckan-cluster", { region: "nyc1", // Choose the region appropriate for you version: "latest", // Use the latest available version of Kubernetes nodePool: { name: "default", size: "s-2vcpu-2gb", // Choose the appropriate size for your workload nodeCount: 2, // Specify the number of nodes in the node pool }, }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Use the Digital Ocean cluster as our Kubernetes provider const provider = new k8s.Provider("doks-provider", { kubeconfig: kubeconfig, }); // Deploy the CKAN Helm Chart to our cluster const ckanChart = new k8s.helm.v3.Chart("ckan", { chart: "ckan", version: "2.8.2", // Use the version that suits your requirement fetchOpts: { repo: "https://raw.githubusercontent.com/kubernetes/charts/master/stable/", // The repository url where CKAN chart is located }, }, { provider }); // Export the URL to access the deployed CKAN instance // Assuming that the CKAN chart exposes a LoadBalancer service to access the application const frontend = ckanChart.getResourceProperty("v1/Service", "ckan-ckan", "status"); export const frontendUrl = pulumi.interpolate`http://${frontend.apply(front => front.loadBalancer.ingress[0].ip)}`;

    What we have now is a Pulumi program that:

    • Provisions a new Kubernetes cluster on Digital Ocean.
    • Sets up a provider to deploy resources on that cluster.
    • Deploys CKAN onto the cluster using its Helm chart.

    After running pulumi up, this will result in a running instance of CKAN on your Digital Ocean Kubernetes cluster. To clean up the resources, run pulumi destroy.

    Remember to review the configurations such as the node size, region, and CKAN chart version to suit your requirements and constraints, and ensure the CKAN repository URL matches the location of the chart version you wish to deploy.
