1. Deploy the chaosmesh-app helm chart on Opensshift

    TypeScript

    To deploy the chaosmesh-app Helm chart on OpenShift using Pulumi, you would use the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider. This resource allows you to deploy a Helm chart from a repository to a Kubernetes cluster, including an OpenShift cluster, since OpenShift is Kubernetes with additional features.

    Before you start writing the Pulumi program, ensure you have the following prerequisites in place:

    1. Pulumi CLI installed on your local machine.
    2. Access to an OpenShift cluster and the appropriate context configured in your local kubeconfig file.
    3. Helm chart repository that contains the chaosmesh-app chart, or the Helm chart files locally.

    Here is a detailed Pulumi program written in TypeScript that deploys the chaosmesh-app Helm chart to an OpenShift cluster:

    import * as k8s from '@pulumi/kubernetes'; import * as pulumi from '@pulumi/pulumi'; // Create a new Kubernetes provider instance that uses the context for your OpenShift cluster. // Ensure that your kubeconfig is correctly set up to point to your OpenShift cluster. const openshiftProvider = new k8s.Provider('openshiftK8s', { kubeconfig: '<YOUR_KUBECONFIG_CONTENT_HERE>' }); // Deploy the 'chaosmesh-app' Helm chart to the OpenShift cluster. const chaosMeshAppChart = new k8s.helm.v3.Chart('chaosmesh-app', { // Specify the chart, version and repository if it's not a local chart // For a local chart, you can set the `path` property to the directory containing your Helm chart files chart: 'chaosmesh-app', version: '<HELM_CHART_VERSION>', // Specify the version of the chart repositoryOpts: { repo: 'https://charts.chaos-mesh.org', // Replace with the URL of the chart repository if necessary }, // Set values for the Helm chart as needed. values: { // Provide custom values for the Helm chart here, e.g., // replicaCount: 1, // image: { repository: 'my-repo/my-image', tag: 'v1.2.3' }, // These would override default values in the Helm chart's `values.yaml` file } }, { provider: openshiftProvider }); // Export the necessary details, like the Helm release status or service URLs. export const chaosMeshAppStatus = chaosMeshAppChart.status // The status of the Helm release export const chaosMeshAppServiceUrl = chaosMeshAppChart.getResourceProperty('v1/Service', 'chaosmesh-app', 'spec.clusterIP'); // Export the ClusterIP of the service

    Here's a breakdown of the program:

    1. Provider Configuration: The @pulumi/kubernetes package is imported to manage Kubernetes resources. A new instance of Provider is created, which specifies the kubeconfig for your OpenShift cluster.

    2. Deploy Helm Chart: The k8s.helm.v3.Chart class is used to represent a Helm chart installation within your OpenShift cluster. You need to specify the name of the Helm chart, the version, and optionally the Helm repository where the chart is hosted. The values specific to the chaosmesh-app Helm chart can also be provided in the values property.

    3. Exports: Exports are used to output the deployment status and any other relevant information, like service URLs or external IPs. You can access these values after deployment by using pulumi stack output.

    Please replace <YOUR_KUBECONFIG_CONTENT_HERE> with the actual content of your kubeconfig file (as a string) and <HELM_CHART_VERSION> with the specific version of the chaos mesh chart you want to deploy.

    After writing and saving the above program in a index.ts file, use the Pulumi CLI to create a new stack and deploy the resources:

    pulumi stack init chaosmesh-deployment pulumi up

    After successful deployment, Pulumi will provide you with the outputs that we have configured to export.
