1. Deploy the slack-git-compare helm chart on Rancher


    Deploying a Helm chart on a Rancher-managed Kubernetes cluster involves several steps. You'll first need a Kubernetes cluster managed by Rancher and then install the desired Helm chart through Rancher's application catalog.

    In this guide, we will go through the process step-by-step using Pulumi and the rancher2 package. Although specific details such as cluster configuration and Helm chart options may vary according to your use case, we'll cover the main components you need to write a Pulumi program to deploy the slack-git-compare Helm chart on Rancher.

    Step 1: Setting Up Your Pulumi Project

    Before you start coding, make sure you have a Pulumi project set up. You can create a new Pulumi project by running pulumi new typescript in your terminal and following the prompts. This will create a new directory with the necessary configuration files to start writing your Pulumi code in TypeScript.

    Step 2: Importing Necessary Libraries

    You'll need to import the Pulumi library for Rancher2 in your TypeScript program. Add rancher2 to your project dependencies using npm or yarn:

    npm install @pulumi/rancher2

    Or if you're using yarn:

    yarn add @pulumi/rancher2

    Step 3: Writing the Pulumi Program

    Now you're ready to write the TypeScript program to deploy the slack-git-compare Helm chart. You'll need to use the rancher2 package for creating a new app within your Rancher cluster and point it to the slack-git-compare Helm chart repository.

    Step 4: Deploying the Chart

    Once you have the Pulumi program ready, you'll run pulumi up to execute it. Pulumi will reach out to your Rancher setup, authenticate with the credentials you've provided, and deploy the slack-git-compare Helm chart according to your specifications.

    Below is a TypeScript program that uses Pulumi to deploy a Helm chart on Rancher. This program assumes you have a running Rancher cluster and appropriate access permissions to deploy Helm charts:

    import * as rancher2 from "@pulumi/rancher2"; import * as pulumi from "@pulumi/pulumi"; // Provide the Rancher cluster ID you wish to deploy the Helm chart to const clusterId = "your-cluster-id"; // Replace 'slack-git-compare' with the actual name and repo of the Helm chart if needed. // If 'slack-git-compare' is not a chart available in a public repository, you would need to add your own catalog to Rancher and use that instead. const slackGitCompareHelmChart = { chart: "slack-git-compare", repo: "your-helm-chart-repo", // Provide additional chart values here }; // Create a new catalog for Rancher. If 'slack-git-compare' is available in an existing catalog, this step is not necessary. const catalog = new rancher2.CatalogV2("catalog", { clusterId: clusterId, url: slackGitCompareHelmChart.repo, }); // Deploy the Helm chart as a Rancher app. You would reference the catalog here if necessary. const slackGitCompareApp = new rancher2.AppV2("slack-git-compare-app", { clusterId: clusterId, namespace: "default", // change to the namespace in which you wish to deploy repoName: catalog.name, chartName: slackGitCompareHelmChart.chart, // Set values for the Helm chart here }); // Export the app name export const appName = slackGitCompareApp.metadata.apply(meta => meta.name);

    Before running pulumi up with this code, ensure that you have replaced placeholders, such as your-cluster-id and your-helm-chart-repo, with actual values from your environment. If the slack-git-compare chart is not in a public Helm repository or requires additional configuration like custom values, you'll need to adjust the chart, repo, and other settings accordingly.

    Step 5: Applying Your Changes

    After the program is ready, you can deploy it using the Pulumi CLI:

    pulumi up

    This command will start the deployment process, and if everything is set up correctly, it will deploy the slack-git-compare Helm chart to your specified Rancher cluster. Follow the command-line prompts to review and approve the changes.


    This program provides a starting point for automating the deployment of Helm charts on a Rancher-managed Kubernetes cluster using Pulumi in TypeScript. For actual deployment, you may need to map additional chart-specific configurations into the Helm chart values. Always refer to the Helm chart's documentation and your Rancher setup to ensure that the configurations are correct.
