1. Deploy the zetcd helm chart on Rancher


    Deploying a Helm chart on a Rancher-managed Kubernetes cluster involves several steps. Rancher provides a comprehensive way to manage Kubernetes clusters with a single control pane. Pulumi's Rancher 2 provider allows you to use Rancher's capabilities within your Pulumi program to deploy Helm charts among other things.

    Before you execute a Pulumi program that deploys the zetcd Helm chart on Rancher, you need to set up your Rancher server, create a Kubernetes cluster managed by Rancher, and install and configure the Pulumi CLI and the Rancher 2 provider. Once you have those prerequisites in place, you'll need to perform the following steps in your Pulumi program:

    1. Import the necessary Pulumi and Rancher 2 packages.
    2. Create or select the Rancher Kubernetes cluster where the Helm chart will be deployed.
    3. Deploy the zetcd Helm chart to the cluster using Rancher 2's App resource.

    Below is a TypeScript program that demonstrates the deployment of the zetcd Helm chart on a Rancher-managed Kubernetes cluster. Please adjust the specifics such as the clusterId, projectId, and the Helm chart values according to your actual setup and needs.

    import * as pulumi from '@pulumi/pulumi'; import * as rancher2 from '@pulumi/rancher2'; // This is a program that deploys the zetcd Helm chart on a Rancher-managed Kubernetes cluster. // The 'App' class represents a helm chart within the Rancher 2 provider. It allows you to deploy, // configure, and manage Helm charts from a Rancher instance. const zetcdHelmChart = new rancher2.App("zetcd-helm-chart", { // Replace 'clusterId' and 'projectId' with the actual IDs of your Rancher Kubernetes Cluster and project. clusterId: "<RANCHER_CLUSTER_ID>", projectId: "<RANCHER_PROJECT_ID>", // The name of the helm chart to deploy. name: "zetcd", // The namespace in which to deploy the helm chart. // Make sure this namespace exists in your Rancher Kubernetes cluster. targetNamespace: "default", // Information about the helm chart repository. externalId: "catalog://?catalog=helm&template=zetcd&version=<CHART_VERSION>", // Specify any custom values needed for the helm deployment. // Refer to the zetcd Helm chart documentation for which values can be set. valuesYaml: ` replicaCount: 3 # ... other custom values ... `, }); // Export the name of the deployed Helm chart. export const chartName = zetcdHelmChart.name;

    In the above program, we use the rancher2.App class to represent the zetcd Helm chart. The clusterId and projectId are placeholders for the respective identifiers of your Rancher cluster and project where the Helm chart will be deployed. Make sure to replace them with the actual IDs from your Rancher setup. The externalId parameter specifies the Helm chart to be deployed using a catalog URL where you should replace <CHART_VERSION> with the version number of the zetcd chart you want to use.

    The valuesYaml field allows you to specify any custom values required by the Helm chart. These values should be set according to the specific configuration parameters supported by the zetcd Helm chart. You can find these parameters documented in the zetcd Helm chart's repository or official documentation.

    Finally, the program exports the name of the deployed Helm chart as a stack output.

    Please ensure you have the Rancher cluster configured, and the access credentials for it are set up. This program assumes that you've already created a cluster in your Rancher account and have permission to deploy apps in the designated project and namespace.
