1. Deploy the chaosmesh-app helm chart on Azure Managed Openshift Service

    TypeScript

    To deploy the chaosmesh-app Helm chart on an Azure Managed OpenShift Service using Pulumi, you would take the following steps:

    1. Create an instance of Azure Managed OpenShift Service.
    2. Deploy the chaosmesh-app Helm chart onto the OpenShift cluster.

    Here is a detailed walkthrough of the Pulumi program written in TypeScript to accomplish the deployment.

    First, you define a new OpenShift Managed Cluster. The Azure Native provider is used to provision the cluster on Azure. The azure-native.containerservice.OpenShiftManagedCluster resource is used to achieve this. Note that you'll need to define the cluster's configuration details, such as the location, the OpenShift version, resource group, and specifics for the agent pool.

    Second, you deploy the Helm chart using the kubernetes.helm.v3.Chart resource from the Kubernetes provider. This resource manages the Helm chart deployment. chaosmesh-app will be specified as the chart name, and you'll provide the repository URL if it's not a standard Helm repo.

    Let's define the Pulumi program:

    import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Define the OpenShift Managed Cluster resource const openShiftCluster = new azure.containerservice.OpenShiftManagedCluster("myOpenShiftCluster", { // Enter details according to your specific Azure configuration and requirements resourceGroupName: "<RESOURCE_GROUP_NAME>", location: "<LOCATION>", // e.g., "East US" openShiftVersion: "<OPENSHIFT_VERSION>", // e.g., "4.6" agentPoolProfiles: [{ name: "agentpool", count: 3, vmSize: "Standard_DS3_v2", osType: "Linux", // You will need to specify the subnetCidr if you have a custom VNET configuration subnetCidr: "<YOUR_SUBNET_CIDR>", }], // Authentication details here // Network profile and any other required configurations… }); // Kubernetes provider to interact with the OpenShift cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: openShiftCluster.kubeconfigs[0].value.apply(x => x), }); // Deploy chaosmesh-app using Helm chart const chaosMeshApp = new k8s.helm.v3.Chart("chaosmesh-app", { // If chaosmesh-app is not in the standard repository, specify the `repo` property accordingly chart: "chaosmesh-app", // You would need to specify `version` if you want a specific version of the chart // values: {}, // Add any values required for the Helm chart here }, { provider: k8sProvider }); // Export the cluster's kubeconfig as an output export const kubeconfig = openShiftCluster.kubeconfigs[0].value; // The following export can be used to bring up the Web UI for the deployed chaos mesh, once external IP is assigned export const chaosMeshWebUI = chaosMeshApp.getResourceProperty("v1/Service", "chaosmesh-app", "status").apply(status => status.loadBalancer.ingress[0].ip);

    In the program:

    • Replace <RESOURCE_GROUP_NAME>, <LOCATION>, <OPENSHIFT_VERSION>, and <YOUR_SUBNET_CIDR> with the respective values that fit your deployment scenario.
    • The openShiftVersion should be a supported version according to Azure's offer.
    • The kubeconfig export provides the configuration that you can use with kubectl command-line tool to interact with your OpenShift cluster once it's ready.
    • The chaosMeshWebUI export provides the IP address for the Chaos Mesh web UI, which can be accessed through the browser to manage experiments once the external IP is assigned to it by Azure. Note that you might need to adjust the resource name and kind based on the actual service details created by the Helm chart.

    This program assumes that you have already set up the Pulumi CLI, authenticated to Azure, and have the necessary permissions to create and manage resources in your Azure subscription. Make sure that OpenShift is supported in the region you're deploying to, and that you've accepted any legal terms required for using OpenShift on Azure.

    Deploy this program using Pulumi by running pulumi up. If there are any configuration parameters required by the chaosmesh-app Helm chart that wasn't supplied, make sure to fill in the values field in the Chart resource accordingly.
