Deploy the atlassian-jira helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy the Atlassian JIRA Helm chart on a Rancher-managed Kubernetes cluster, you will need to perform the following steps:

1. Ensure that you have a Kubernetes cluster managed by Rancher.
2. Deploy the Helm chart to your Kubernetes cluster through Rancher.

Before you begin the actual deployment, make sure that you have the following prerequisites in place:

- A Rancher instance up and running.
- A Kubernetes cluster registered with Rancher.
- Pulumi installed and configured for use with your Rancher instance.

In the Pulumi program, you'll take advantage of the `rancher2` provider to interact with your Rancher instance. First, you need to create a Catalog which holds information on the Helm chart you want to deploy. After that, you can use a `HelmChart` resource from the Rancher2 provider to deploy the JIRA chart into the cluster managed by Rancher.

Here's a Pulumi program written in TypeScript that demonstrates how to perform these steps. Note that the specifics of the Helm chart configuration (such as values, version, etc.) may vary depending on the chart itself, so you should adjust this accordingly based on the official documentation or your specific needs.

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

// Assuming your Pulumi configuration is set up with the required Rancher2 provider configuration.
// If not, you may need to specify the provider configuration parameters.
// Refer to Rancher2 provider documentation for more details.

// Create a new Rancher2 Catalog resource. This tells Rancher where to find the Helm chart for Atlassian JIRA.
const jiraCatalog = new rancher2.CatalogV2("jira-catalog", {
  // Generally, you'd get the Helm repository URL from the documentation or the provider of the software. For JIRA, this is typically Atlassian's own chart repository.
  url: "https://atlassian.github.io/data-center-helm-charts", // Replace with the actual repository URL if different.
  clusterId: "the-cluster-id", // Replace with your actual cluster ID in Rancher.
});

// Deploy the Atlassian JIRA Helm chart to the Kubernetes cluster.
const jiraHelmChart = new rancher2.AppV2("jira-helm-chart", {
  // The namespace where the Helm chart will be installed. Ensure this namespace exists in your cluster.
  namespace: "jira",

clusterId: "the-cluster-id", // Replace with your actual cluster ID in Rancher.
  repoName: jiraCatalog.name,
  chartName: "atlassian-jira", // Replace with the exact chart name for Atlassian JIRA.

// Set your desired chart version and values. These can be obtained from the documentation for the Helm chart.
  chartVersion: "1.2.3", // Replace with the version you want to deploy.
  values: `# Use | to write multi-line string values in YAML.
# Example JIRA configuration:
jira:
  # Define the necessary values for your JIRA installation
  # This might include database configuration, replica count, etc.
  `
  // Other chart values can be set here as needed.
  // Refer to the Helm chart's `values.yaml` or documentation for configuration options.
}, { dependsOn: [jiraCatalog] }); // Ensure the Helm chart is installed after the catalog is created.
```

This program creates a Rancher2 catalog pointing to the Helm repository that hosts the Atlassian JIRA Helm chart, then it sets up an application using this catalog.

Make sure to replace placeholders like `the-cluster-id` with the actual values that are appropriate for your Rancher-managed cluster.

In real-world usage, you should review the JIRA Helm chart's `values.yaml` file and provide appropriate values that match your desired deployment configuration. These values typically configure various aspects of the deployment, such as:

- The number of JIRA replicas
- Resources and limits (CPU, memory)
- Database configuration (may be external or a sub-chart)
- Ingress settings (hostnames, TLS configuration)
- Persistence options (storage class, size)

After you have set up and executed this Pulumi program, your resulting deployment should have the JIRA Helm chart running on your Kubernetes cluster managed by Rancher.

Remember, these are just the first steps, and the actual deployment may require more fine-tuning and additional configuration based on your specific needs and the features provided by the Atlassian JIRA Helm chart. Always refer to the official Helm chart documentation for comprehensive instructions and configurations.
