1. Deploy the sentry-kubernetes helm chart on Opensshift


    Deploying a Helm chart on an OpenShift cluster using Pulumi can be achieved using the kubernetes.helm.v3.Chart resource. This resource allows you to declare the desired state of a Helm chart in a Pulumi program. To use it with OpenShift, you'll need to have your OpenShift cluster’s kubeconfig available to Pulumi, typically by configuring it in the environment where you run Pulumi commands.


    Here's what you'll need to do in broad strokes:

    1. Set up your Pulumi project: Ensure your Pulumi project is properly set up to interact with your Kubernetes/OpenShift cluster. This includes installing necessary libraries and setting up authentication.

    2. Create a Helm Chart resource: Define a Chart resource in your Pulumi program. You will specify the chart name (sentry-kubernetes), release name, version, any custom configurations, and the repository where the chart is hosted.

    3. Deploy the Helm Chart: Run the pulumi up command to preview and deploy the Helm chart to your OpenShift cluster. Pulumi will interact with the Helm client and OpenShift API to deploy your application.

    Below is a sample Pulumi program written in TypeScript that models this deployment:

    Pulumi Program

    import * as pulumi from '@pulumi/pulumi'; import * as k8s from '@pulumi/kubernetes'; // The configuration for deploying the sentry-kubernetes Helm chart. const chartName = 'sentry-kubernetes'; const releaseName = 'sentry'; const chartVersion = 'x.x.x'; // Specify the chart version you want to deploy. const chartRepo = 'https://sentry-kubernetes.repo'; // Replace with the actual Sentry chart repository URL. // Create a Chart resource using the Helm Chart class. const sentryChart = new k8s.helm.v3.Chart(releaseName, { chart: chartName, version: chartVersion, fetchOpts: { repo: chartRepo, }, // You can specify namespace if needed, and include additional configurations here. }, { // Associate with the provider that points to your OpenShift cluster. // If use the default kubeconfig context, you don't have to set the provider field. }); // Export the URL of the sentry application frontend, if it is available as a service with Ingress or Route. export const sentryUrl = sentryChart.getResourceProperty('v1/Service', 'sentry-web', 'status').apply(status => { // This is highly dependent on how the Service and Ingress/Route are set up in the Helm chart. // You may need to modify this logic to align with your specific deployment details. return status.loadBalancer?.ingress[0]?.hostname || status.loadBalancer?.ingress[0]?.ip; });

    Details about Resources

    • @pulumi/kubernetes: This is the Pulumi Kubernetes package that allows you to manage Kubernetes resources.

    • k8s.helm.v3.Chart: Represents a Helm Chart in Kubernetes. This class provides a way to deploy all sorts of applications packaged as Helm charts onto a Kubernetes cluster.

    • chart: The name of the chart you wish to deploy. In this case, we are deploying sentry-kubernetes.

    • version: Specifies the version of the Helm chart to install. Replace x.x.x with the appropriate chart version.

    • fetchOpts: An options block allows you to specify Helm fetch parameters such as the repository, which might require credentials and other settings.

    • provider: Specifies the Kubernetes provider. If you skip this, Pulumi uses the default provider configured with the kubeconfig on your machine.

    • sentryUrl: Exposes the URL where the Sentry application can be accessed. Retrieving the URL depends on how the Service and Ingress/Route are defined in the Helm chart. You will need to adjust this based on the specifics of the Sentry chart and how services are exposed in your OpenShift cluster.

    Running the Program

    1. Install the Pulumi CLI and configure it to work with your language of choice.
    2. Create a new Pulumi project, or navigate to your existing one.
    3. Ensure you have the OpenShift kubeconfig correctly set up on your local system or CI/CD environment.
    4. Save the above program to a .ts file in your Pulumi project.
    5. Run pulumi up to preview and deploy the chart.

    Remember to substitute placeholder values (like the chart version or repository URL) with actual values for your deployment. Make sure all necessary dependencies are installed, which usually involves running npm install or another package manager command for your language.
