Deploy the ibm-mqadvanced-server-dev helm chart on Rancher

Question

Pulumi · Accepted Answer

Deploying an IBM MQ Advanced Server Developer Edition Helm chart on Rancher involves multiple steps. Rancher is a complete software stack for teams adopting containers, and it allows you to run and manage containers in production. Helm is a package manager for Kubernetes, which allows you to define, install, and upgrade even the most complex Kubernetes applications.

To deploy a Helm chart using Pulumi with the Rancher 2 provider, you would typically take the following high-level steps:

1. Set up the Pulumi environment for TypeScript (or your chosen language).
2. Configure the necessary Rancher 2 provider and Kubernetes provider if needed.
3. Create a new Rancher2 `CatalogV2` resource that points to the Helm chart repository, if it is not already available in the Rancher2 environment.
4. Deploy the Helm chart to the desired Rancher project and cluster.

Below is an illustrative Pulumi program in TypeScript that demonstrates how to perform these steps. Please note that you will need to have Pulumi installed, have access to a Rancher instance, and should have the Pulumi CLI configured with the necessary credentials to interact with your Rancher server.

Here's a program that you can use as a starting point:

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as rancher2 from "@pulumi/rancher2";

// You would need to change these values to match your Rancher setup
const rancherServerUrl = "https://your-rancher-server-url";
const helmChartName = "ibm-mqadvanced-server-dev";
const helmChartVersion = "x.y.z"; // Specify the chart version you want to deploy
const clusterId = "your-cluster-id"; // The ID of the cluster to which you want to deploy
const projectId = "your-project-id"; // The ID of the Rancher project

// Create a new Rancher Catalog that includes the IBM MQ Helm chart repository
const catalog = new rancher2.CatalogV2("ibm-mq-catalog", {
    clusterId: clusterId,
    url: "https://raw.githubusercontent.com/ibm/charts/master/repo/stable/", // The URL of the Helm chart repository
    gitBranch: "master",
});

// Deploy IBM MQ Helm chart into the specified Rancher project and cluster
const ibmMqHelmChart = new rancher2.AppV2("ibm-mq-app", {
    clusterId: clusterId,
    projectId: projectId,
    repoName: catalog.name,
    chartName: helmChartName,
    chartVersion: helmChartVersion,
    // You may need to configure values to customize the Helm chart deployment
    values: `
service:
  type: LoadBalancer
`,
});

// Export the endpoint of the deployed IBM MQ service
export const ibmMqEndpoint = pulumi.interpolate`${rancherServerUrl}/${ibmMqHelmChart.name}`;

```

This program does the following:

- Imports the necessary Pulumi and rancher2 packages.
- Sets up variables for your Rancher server URL, the Helm chart details, and the cluster and project IDs.
- Creates a new `CatalogV2` resource for the IBM Helm chart repository using `rancher2.CatalogV2`. This catalog resource allows Rancher to access Helm charts from this repository.
- Deploys the `ibm-mqadvanced-server-dev` Helm chart into the specified cluster and project using `rancher2.AppV2`. The `values` property can be used to pass custom configuration to the Helm chart. Here we've set the service type to `LoadBalancer`, but you may need to adjust this to fit the specifics of your environment or Helm chart configuration.
- Exports the Helm release's endpoint URL.

Ensure that you have the correct Helm chart repository URL and that your cluster and project information match your Rancher environment. Also, update the `values` configuration to match the Helm chart's requirements and your desired setup.

To run this Pulumi program:

1. Save the code in a file with a `.ts` extension, for example, `deployIbmMqHelmChart.ts`.
2. Run `pulumi stack init` to create a new stack if you haven't already done so.
3. Run `pulumi up` to preview and deploy the changes.

You will see the Pulumi CLI outputting updates on the deployment process, and upon completion, you will receive the endpoints and other outputs as defined in the program. If new to Pulumi, please follow the [Getting Started with Pulumi](https://www.pulumi.com/docs/get-started/) guide which will help you with the initial setup.
