1. Deploy the datadog-apm helm chart on Opensshift

    TypeScript

    Deploying a Helm chart on an OpenShift cluster can be a straightforward task with Pulumi. In this case, you want to deploy the Datadog APM Helm chart on an OpenShift cluster. OpenShift is a Kubernetes-based platform, and Pulumi has a Kubernetes provider that can deploy Helm charts. The resource you'll use for this task is kubernetes.helm.v3.Chart, a Pulumi resource that allows you to deploy Helm charts to a Kubernetes cluster.

    Here's how you can achieve this with Pulumi:

    1. Install Pulumi CLI and Set Up OpenShift: Before you start, you need to have Pulumi CLI installed on your system and have your OpenShift cluster ready. You need to have kubectl configured to communicate with your OpenShift cluster.

    2. Create a New Pulumi TypeScript Project: Start by creating a new Pulumi project for TypeScript.

    3. Define Your Configuration and Helm Chart Details: In your Pulumi program, you'll specify the Chart details such as the name, repository, and any custom values you may want to pass to the Helm chart.

    4. Deploy the Helm Chart Using Pulumi: Finally, you'll invoke the Pulumi deployment which will interpret your TypeScript program to deploy the Datadog APM Helm chart to your OpenShift cluster.

    Below, you'll find a Pulumi TypeScript program that deploys the Datadog APM Helm chart on an OpenShift cluster. The main steps include importing the necessary Pulumi packages, creating an instance of the Chart resource, and specifying the necessary chart details and configurations.

    import * as k8s from '@pulumi/kubernetes'; const datadogApmChart = new k8s.helm.v3.Chart('datadog-apm', { // Replace with the actual chart name if different and its repository chart: 'datadog', version: '2.10.13', // Specify the chart version you want to deploy fetchOpts: { repo: 'https://helm.datadoghq.com/', }, // Define the values you would like to override, as per the chart's values.yaml file values: { datadog: { apm: { // Enable APM and set associated configurations here enabled: true, }, apiKey: 'YOUR_DATADOG_API_KEY', // Replace with your Datadog API key // Assuming you want to use the Datadog Operator // When using the operator, you might need to specify apiKeySecretName instead }, // Include other Datadog configurations as necessary }, namespace: 'default', // Specify the namespace you're deploying to, use 'default' or any custom namespace }, { provider: k8sProvider }); // Ensure you provide a Pulumi Kubernetes Provider associated with your OpenShift cluster // Exports a Helm release status artifact that describes the deployed release export const releaseName = datadogApmChart.status.name;

    What's happening in the code?

    • We import the @pulumi/kubernetes package which is the Pulumi SDK for Kubernetes.

    • We create a new Chart resource, datadog-apm, using the details from the Datadog Helm chart. You need to replace YOUR_DATADOG_API_KEY with an actual Datadog API key.

    • The parameter version specifies the version of the Helm chart you wish to deploy. You should replace '2.10.13' with the appropriate version number according to the chart you are using.

    • We use the values property to override the default settings of the Helm chart, in this case, enabling APM, among other configurations. You may need to fine-tune these values depending on your specific configuration or Datadog's helm chart version.

    • By exporting releaseName, you can retrieve the name of the Helm release from the stack's outputs when it's deployed, which is useful for management or CI/CD purposes.

    Keep in mind that you also need an instance of k8s.Provider configured for your OpenShift cluster to let Pulumi communicate with it. This wasn't defined in this code since it typically depends on the specific configuration of your OpenShift cluster, including the authentication method you are using.

    Remember to replace placeholders with real values before running the program, especially the YOUR_DATADOG_API_KEY part with a valid Datadog API key. You may also want to customize the namespace or any other configurations according to your cluster setup or the Datadog helm chart specifics.

    To apply this program, run pulumi up after you finish defining your Pulumi program. The command will establish communication with your cluster and apply the desired state as described by your TypeScript code. If there's any error or resource conflict, Pulumi will provide detailed output to help you diagnose and fix the issues.
