1. Deploy the argocd-config helm chart on Linode Kubernetes Engine


    To deploy the argocd-config Helm chart on Linode Kubernetes Engine (LKE), you first need an LKE cluster where the Helm chart will be deployed. The steps for this deployment include setting up the Kubernetes cluster on Linode and then using Pulumi’s Kubernetes provider to deploy the argocd-config Helm chart.

    Let's start with the steps required for this deployment:

    1. Creating a Linode Kubernetes Engine Cluster: You need to create a LKE cluster which can be done using Linode's own APIs or tools. Ensure that kubectl is configured to interact with your cluster.

    2. Setting up Pulumi: Install Pulumi and set up your Pulumi account. Make sure that Pulumi CLI is installed on your machine and that you’re logged into the Pulumi service.

    3. Deploying the Helm Chart with Pulumi: Use Pulumi's Kubernetes provider to deploy the Helm chart to your cluster.

    Below is the Pulumi program written in TypeScript which shows you how to deploy the argocd-config Helm chart to an LKE cluster. This assumes you have already set up your LKE cluster and have the kubeconfig available to interact with your cluster.

    import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes Provider instance that uses our kubeconfig from Linode Kubernetes Engine. const provider = new k8s.Provider("lke-provider", { // Replace `<YOUR_KUBECONFIG_CONTENT>` with the actual kubeconfig content for your LKE cluster. kubeconfig: `<YOUR_KUBECONFIG_CONTENT>`, }); // Deploy the 'argocd-config' Helm chart using the Helm Chart resource provided by Pulumi. const argocdConfigChart = new k8s.helm.v3.Chart("argocd-config", { chart: "argo-cd", // Make sure this is the chart name that corresponds to 'argocd-config'. version: "<CHART_VERSION>", // Specify the version of the Helm chart you would like to deploy. // `fetchOpts.repo` provides the repository URL where the chart can be found if it's not in the default Helm repos. fetchOpts: { repo: "https://argoproj.github.io/argo-helm" }, }, { provider }); // Export the endpoint to access Argo CD server. export const argoCdServer = argocdConfigChart.getResourceProperty("v1/Service", "argocd-config-argocd-server", "status") .apply(status => status.loadBalancer.ingress[0].ip); // This will get the LoadBalancer IP if available.

    Remember to replace <YOUR_KUBECONFIG_CONTENT> with your actual kubeconfig content that you'll get from Linode after setting up your Kubernetes cluster. And <CHART_VERSION> should be replaced with the specific version of the argo-cd Helm chart that you want to deploy. Also, verify that the chart name argo-cd is correct as it should match the name provided for argocd-config; if it's different, update it accordingly.

    In the above program:

    • We import the Kubernetes package from Pulumi and create a Kubernetes provider which will interact with our LKE cluster.
    • We then define a Helm Chart resource to deploy Argo CD using its Helm chart from the official Argo project Helm repository.
    • Finally, we export a stack output argoCdServer, which will hold the IP address to access the Argo CD server. Note that this will only work correctly if Argo CD is exposed via a LoadBalancer service in the deployed Helm chart.

    After you've replaced the placeholders with actual values, run this code using the Pulumi CLI. Navigate to the directory containing your Pulumi program and then use the following commands:

    pulumi up

    This command starts the deployment process. Pulumi will print out the proposed changes and ask for confirmation before proceeding to deploy the resources on LKE.

    After the deployment, if you wish to update the chart or its values, you can modify the program and run pulumi up again. Pulumi will compute the minimal diff, update the deployment, and show you the changes.
