1. Deploy the simple-mongodb helm chart on Opensshift


    To deploy a Helm chart on OpenShift using Pulumi, we'll need to focus on a few steps:

    1. Setting up a Kubernetes provider to interact with your OpenShift cluster.
    2. Using the Pulumi Kubernetes provider's helm.v3.Chart resource to deploy a Helm chart.

    Before you begin, ensure that you have kubectl configured with access to your OpenShift cluster and that your Pulumi environment is set up. Additionally, you should have the Helm CLI installed to fetch or inspect Helm charts if needed.

    Here's a program that demonstrates how to deploy the simple-mongodb Helm chart on an OpenShift cluster using Pulumi with TypeScript:

    import * as kubernetes from "@pulumi/kubernetes"; // This is your OpenShift cluster configuration const openShiftClusterConfig = { kubeconfig: "./kubeconfig.yaml" // Path to your OpenShift kubeconfig file }; // Create a Kubernetes provider instance using the above cluster configuration const openshiftProvider = new kubernetes.Provider("openshift", { kubeconfig: openShiftClusterConfig.kubeconfig }); // Deploy the 'simple-mongodb' Helm chart using the cluster provider const mongodbChart = new kubernetes.helm.v3.Chart("simple-mongodb", { chart: "simple-mongodb", repo: "my-repo", // Replace 'my-repo' with the name of the repository where the chart is hosted version: "1.0.0", // Specify the chart version // Optional: Specify custom values for the Helm chart values: { mongodbUsername: "admin", mongodbPassword: "password", mongodbDatabase: "mydatabase" }, // Specify the namespace where the chart should be deployed namespace: "my-namespace", // Replace 'my-namespace' with the target namespace in your OpenShift cluster }, { provider: openshiftProvider }); // Export the MongoDB service endpoint to access it externally export const mongodbServiceEndpoint = mongodbChart.getResourceProperty("v1/Service", "simple-mongodb", "status.loadBalancer.ingress[0].ip");


    1. First, we import the required Pulumi Kubernetes package and define the OpenShift cluster configuration.
    2. Then, we create a Provider instance that knows how to communicate with your OpenShift cluster, pointing to the kubeconfig file for access credentials.
    3. After that, we deploy the simple-mongodb Helm chart using the helm.v3.Chart class from the Pulumi Kubernetes provider. This requires specifying details such as the chart name, its repository (change 'my-repo' to the actual repository where your chart is hosted), and the version of the chart you wish to deploy.
    4. We've included a values property to specify any custom settings that must be applied to the Helm chart. Adjust these settings to match the configuration you wish to apply to your MongoDB instance.
    5. The namespace property defines the namespace within your OpenShift cluster where the Helm chart will be deployed.
    6. Finally, we export the MongoDB service's endpoint so you can access the database outside the cluster.

    After setting up the above program, you can run the following Pulumi CLI commands:

    • pulumi up to preview and execute the deployment
    • pulumi stack output mongodbServiceEndpoint to get the MongoDB service endpoint after the deployment is completed

    Please ensure the simple-mongodb Helm chart is compatible with your OpenShift cluster version and is configured correctly to work within the constraints of OpenShift's security model. If the simple-mongodb Helm chart requires any OpenShift-specific configurations, ensure they are included in the values object when defining the Helm chart in the Pulumi program.
