1. Deploy the docker-registry-proxy helm chart on Linode Kubernetes Engine


    To deploy the docker-registry-proxy Helm chart on Linode Kubernetes Engine (LKE) using Pulumi, you will need to follow these steps:

    1. Set up a new Pulumi project and configure it for use with Linode.
    2. Define the Kubernetes cluster in Linode using Pulumi.
    3. Install the Helm chart for docker-registry-proxy.

    Below is a TypeScript program that carries out these steps. Before running this code, ensure you have Pulumi installed and configured to access your Linode account. You can configure Pulumi for Linode by setting the LINODE_TOKEN environment variable, which you can obtain from Linode Cloud Manager.

    Pulumi Program

    import * as linode from "@pulumi/linode"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create a new Linode Kubernetes Engine (LKE) cluster const cluster = new linode.LkeCluster("my-cluster", { k8sVersion: "1.22", region: "us-central", tags: ["pulumi-cluster"], pools: [{ type: "g6-standard-1", count: 2, }], }); // Export the cluster KubeConfig export const kubeConfig = cluster.kubeconfig; // Define the provider to interact with your Linode Kubernetes cluster const clusterProvider = new k8s.Provider("my-cluster-provider", { kubeconfig: kubeConfig.apply(config => JSON.stringify(config)), // converts yaml to JSON }); // Deploy the docker-registry-proxy Helm chart on the Linode Kubernetes cluster const registryProxyChart = new k8s.helm.v3.Chart("docker-registry-proxy", { chart: "docker-registry-proxy", // Make sure this repo URL is correct and the chart is available there // It's a placeholder URL for demonstration purposes repo: "https://helm.mydockerregistry.com/charts", namespace: "default", // Add any custom values you need for the 'docker-registry-proxy' chart here values: { // For example, you could set the image pull policy to 'Always' // image: { // pullPolicy: "Always" // } }, }, { provider: clusterProvider }); // Export the URL or any other output information needed to access the proxy after deployment export const registryProxyUrl = pulumi.output(registryProxyChart.getResourceProperty("v1/Service", "default/docker-registry-proxy", "status")).apply(status => status.loadBalancer.ingress[0].ip);


    • We import the required Pulumi libraries for Linode (@pulumi/linode), Kubernetes (@pulumi/kubernetes), and Pulumi itself (@pulumi/pulumi).
    • Next, we create an instance of the Linode Kubernetes Engine cluster with the desired version and node size specified in the pools.
    • We export the kubeconfig of the newly created cluster so that we can use it to interact with the cluster.
    • We define a Pulumi Kubernetes provider (clusterProvider) which uses the exported kubeconfig. This provider is required to interact with the Kubernetes cluster.
    • We deploy the docker-registry-proxy Helm chart to our Linode Kubernetes cluster using Pulumi's Helm Chart resource, k8s.helm.v3.Chart. You will need to replace the repo URL with the actual repository URL where the docker-registry-proxy Helm chart is hosted.
    • We export an output variable, registryProxyUrl, which gives us the external IP address to access the docker registry proxy once deployed.

    Please ensure you customize the chart and repo fields according to your Helm Chart's hosting details and modify the values field if you need to change the default configuration of the chart.

    Run pulumi up in the directory where this code is saved, and Pulumi will perform the deployment. You can see the progress and outputs in your command line interface.
