1. Deploy the choerodon-asgard helm chart on Linode Kubernetes Engine


    To deploy the choerodon-asgard Helm chart on Linode Kubernetes Engine using Pulumi, you will need to do the following:

    1. Set up a Linode Kubernetes Engine (LKE) cluster if you do not have one already.
    2. Install the Pulumi CLI and set up Pulumi to use the Linode provider.
    3. Write a Pulumi program that will use the Pulumi Kubernetes provider to deploy the choerodon-asgard Helm chart to your LKE cluster.

    Here is a step-by-step guide and TypeScript program to help you achieve this:

    Step 1: Set up the Linode Kubernetes Engine Cluster

    Before deploying the Helm chart with Pulumi, ensure you have an LKE cluster running. You can create an LKE cluster through the Linode Cloud Manager or Linode CLI.

    Step 2: Install the Pulumi CLI

    Install the Pulumi CLI on your machine, which will be used to run the Pulumi program. Instructions for installation can be found on the official Pulumi website.

    Step 3: Set up Pulumi to Use the Linode Provider

    Follow the steps on the Pulumi website to set up the Linode provider for Pulumi. This typically involves creating a new Pulumi project and setting appropriate configuration values.

    Step 4: Write the Pulumi Program

    Create a new file named index.ts and write the following program. This program uses the Pulumi Kubernetes provider to deploy the choerodon-asgard Helm chart:

    import * as k8s from "@pulumi/kubernetes"; // Step 1: Configure access to the Linode Kubernetes cluster. You can use a kubeconfig file or set the context programmatically. // Ensure your KUBECONFIG environment variable is set, or pass the kubeconfig explicitly to the provider instance. // Create an instance of the Kubernetes Provider pointing to the Linode cluster const provider = new k8s.Provider("lke-provider", { kubeconfig: process.env.KUBECONFIG, // Alternatively, specify the kubeconfig contents or file path here }); // Step 2: Deploy the choerodon-asgard Helm chart using the kubernetes.helm.v3.Chart resource const choerodonAsgardChart = new k8s.helm.v3.Chart("choerodon-asgard", { chart: "choerodon-asgard", // Name of the chart // If the chart is not from the default Helm repo, specify the `repo` property with the URL of the Helm repository // repo: "URL_TO_THE_HELM_REPO", e.g., "https://charts.example.com/" version: "X.Y.Z", // Replace with the desired chart version // Specify namespace if needed, defaults to 'default' if not provided // namespace: "kube-system", values: { // Place your configuration values here according to 'choerodon-asgard' chart requirements. // Configuration values override the default values provided by the chart. }, }, { provider }); // Pass the provider instance to tie this chart to the Linode cluster // Step 3: Expose relevant information about the deployment, such as service URLs or other details. export const helmReleaseName = choerodonAsgardChart.getResource("v1/Service", "choerodon-asgard");

    This program performs the following actions:

    • Imports the Pulumi Kubernetes library (@pulumi/kubernetes).
    • Configures access to the Linode Kubernetes cluster using the kubeconfig file set in the KUBECONFIG environment variable or a specified string literal.
    • Deploys the choerodon-asgard Helm chart to the specified Kubernetes cluster. You will need to replace "X.Y.Z" with the actual version of the chart you want to deploy. Additionally, you may need to set the repo property if the Helm chart is hosted in a chart repository other than the default Helm chart repository.
    • Exports the name of the Helm release, which can be used to reference the deployed services and other resources.

    Step 5: Run the Pulumi Program

    Open a terminal and navigate to the directory containing index.ts. Run the following commands to deploy the Helm chart:

    pulumi up

    When you execute the pulumi up command, Pulumi will perform a preview of the changes and prompt you for confirmation before it makes any changes to your infrastructure.

    Step 6: Monitor the Deployment

    Pulumi provides detailed information about the infrastructure it's creating, updating, or deleting. You can monitor the status of your deployment in the terminal and through the Pulumi Console.

    Step 7: Access the Deployed Helm Chart

    Once the deployment is successful, you can access the choerodon-asgard services using kubectl or via the Linode Cloud Manager if you need to retrieve the external IP or DNS information.

    Remember to replace any placeholder values, such as the Helm chart version and configuration values, with the actual values for your deployment. If the Helm chart requires configuration via the values property, ensure you fill this out according to the chart's documentation.
