Deploy the ansible-automation-platform helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the Ansible Automation Platform Helm chart on OpenShift, you would typically follow these steps:

1. Set up your OpenShift cluster: Ensure you have a running OpenShift cluster and that you have the appropriate permissions to deploy applications to it.

2. Configure Helm: Helm is a package manager for Kubernetes, which OpenShift is based on. You will need to install Helm on your local machine and configure it to communicate with your OpenShift cluster.

3. Find the Ansible Automation Platform Helm Chart: Locate the Helm chart for the Ansible Automation Platform. This is often available through an official repository or chart registry.

4. Customize the Helm values: Customize the deployment by modifying the `values.yaml` file or by passing configuration values directly to the Helm command when installing the chart.

5. Deploy the chart: Using the `helm install` command, deploy the Ansible Automation Platform into your OpenShift cluster.

In Pulumi, you would typically write a program in TypeScript (or any of Pulumi's supported languages) to automate step 4 and 5 via infrastructure as code. This allows you to codify the application deployment and manage it as part of your infrastructure.

Below is a TypeScript program using Pulumi to deploy the Ansible Automation Platform Helm chart on an OpenShift cluster. This assumes you already have an existing OpenShift cluster and Pulumi installed.

First, let's explain the key components we'll be using:
- `kubernetes.helm.sh/v3.Chart`: This Pulumi resource allows you to deploy a Helm chart to a Kubernetes cluster. In this case, we will use it to deploy the Ansible Automation Platform to OpenShift.

Now let's write the program:

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as k8s from "@pulumi/kubernetes";

// Initialize a Kubernetes provider to connect to the OpenShift cluster
const k8sProvider = new k8s.Provider("openshift", {
  // Specifies the Kubernetes cluster from the configuration. This should point to your OpenShift cluster.
  // Make sure you have configured kubectl to point to your OpenShift cluster
  kubeconfig: pulumi.output({value: process.env.KUBECONFIG}),
});

// Deploy the Ansible Automation Platform Helm chart
const ansibleAutomationPlatformChart = new k8s.helm.sh.v3.Chart("ansible-automation-platform", {
  chart: "ansible-automation-platform", // Replace with the correct chart name if needed
  // Specify the repository if the chart is not in the default Helm chart repository
  fetchOpts: {
    repo: "https://charts.ansible.com/ansible-automation-platform", // Replace with the correct repository URL if needed
  },
  // Specify other values as needed for the chart. These would typically be found in the `values.yaml` file of the Helm chart.
  values: {
    /* 
    These values need to be tailored to your specific needs and match the available
    configuration options for the Ansible Automation Platform Helm chart.
    For example:
    someValue: "some-setting",
    anotherValue: "another-setting",
    */
  },
}, { provider: k8sProvider });

// Export the name of the cluster
export const clusterName = pulumi.output(ansibleAutomationPlatformChart.getResourceProperty(
  "v1/Service", "ansible-automation-platform", "metadata"
)).apply(metadata => metadata.name);
```

Here's what the program does:
- It initializes a Pulumi provider for Kubernetes, which is configured to target your existing OpenShift cluster using `kubeconfig`.
- It deploys the Ansible Automation Platform using the corresponding Helm chart by creating a `Chart` resource.
- It takes the necessary configuration parameters for the Helm chart, such as the repository from where the Helm chart will be fetched and other values that may configure the Helm chart as required.
- It exports the name of the service created by the Helm chart as a stack output, which you can use to retrieve information about the deployment.

Remember to configure the `values` property of the `Chart` resource to fit the configuration specific to the Ansible Automation Platform Helm chart and your deployment needs.

To run this Pulumi program, you save it to a file (e.g., `index.ts`), ensure all dependencies are installed via npm (including `@pulumi/pulumi` and `@pulumi/kubernetes`), and then simply run `pulumi up`. This will trigger Pulumi to provision the resources as declared in the program.

Since you're a novice, if you need step-by-step instructions or encounter any issues, I'd recommend checking out Pulumi's [Getting Started](https://www.pulumi.com/docs/get-started/kubernetes/) guide for working with Kubernetes which will cover the fundamentals.
