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


    I will assist you in deploying the mtls-proxy Helm chart onto a cluster managed by Linode Kubernetes Engine using Pulumi and TypeScript. We will use the kubernetes Pulumi provider, which allows us to interact with Kubernetes resources, including deploying Helm charts, from our Pulumi program.

    Before starting, you should have Pulumi installed and configured for use with your Linode account. You should also have a Kubernetes cluster already running on Linode Kubernetes Engine and have the kubeconfig for that cluster available on your machine where you'll run Pulumi. These steps are necessary because Pulumi uses the kubeconfig file to interact with your Kubernetes cluster.

    As for the mtls-proxy Helm chart, you would need the following information:

    • The repository URL where the Helm chart is located, if it's not part of the default Helm chart repositories.
    • Any specific configuration parameters you want to set for the Helm chart deployment.

    Below is the Pulumi program in TypeScript to deploy the mtls-proxy Helm chart to Linode Kubernetes Engine:

    import * as k8s from "@pulumi/kubernetes"; // Replace the following variables according to your setup. // If the Helm chart you want to install is not in the Helm stable repository, you need to provide the repo URL. const helmRepoName = "<HELM_REPO_NAME>"; const helmRepoUrl = "<HELM_REPO_URL>"; const helmChartName = "mtls-proxy"; const helmChartVersion = "<HELM_CHART_VERSION>"; // Specify the chart version if needed const releaseName = "mtls-proxy-release"; const namespace = "default"; // Specify the namespace where you want to deploy the chart const main = async () => { // Create a Kubernetes provider instance using the current context in your kubeconfig. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: "<YOUR_KUBECONFIG_CONTENTS>", // Ensure you provide your kubeconfig file contents }); // Add the Helm chart repository, if it's a custom repository. const helmRepo = new k8s.helm.v3.Repository("helm-repo", { name: helmRepoName, url: helmRepoUrl, }, { provider: k8sProvider }); // Deploy the mtls-proxy Helm chart using the helm.v3.Chart class from the Pulumi Kubernetes SDK. const mtlsProxyChart = new k8s.helm.v3.Chart(releaseName, { chart: helmChartName, version: helmChartVersion, fetchOpts: { repo: helmRepo.url, }, // Add any custom values you want to use for your Helm chart deployment. values: { // For example, if your chart requires you to specify custom value for a 'key': // key: "value", }, namespace: namespace, }, { provider: k8sProvider }); // Export any necessary output, such as the public URL of a service. // This is just an example, if your chart creates a service with type LoadBalancer, you might want to output its endpoint: // export const serviceUrl = mtlsProxyChart.getResourceProperty("v1/Service", "<SERVICE_NAME>", "status").apply(status => status.loadBalancer.ingress[0].hostname || status.loadBalancer.ingress[0].ip); }; main();

    To run this Pulumi program, follow these steps:

    1. Create a new directory for your Pulumi project.
    2. Navigate into the new directory and run pulumi new typescript to create a new Pulumi TypeScript project.
    3. Install the necessary dependencies with npm install @pulumi/kubernetes.
    4. Replace the contents of index.ts with the provided program above.
    5. Fill in the necessary variables such as helmRepoName, helmRepoUrl, helmChartVersion, releaseName, namespace, and your actual kubeconfig contents.
    6. Run pulumi up to preview and deploy the resources. Pulumi will show you what will be deployed before making any changes.

    Remember to check the values and configurations required by the mtls-proxy Helm chart and adjust the values object in the Chart instantiation accordingly.

    This program will:

    • Configure a Kubernetes provider with your cluster's connection information.
    • Optionally add a Helm chart repository if the mtls-proxy is not in the default Helm repositories.
    • Deploy the mtls-proxy Helm chart into the specified namespace within your Linode Kubernetes cluster.
    • The output can be tailored to export pertinent information, such as service URLs or any other valuable output from the Helm chart deployment.

    Make sure everything is set up correctly, and you have the proper permissions to interact with the Helm repository and deploy resources into the Kubernetes cluster. If you experience issues with deploying, verify that your kubeconfig is correctly set up and that you have correctly inputted all the names and URLs required by the Helm chart and repository.
