1. Deploy the mongodb-replicaset helm chart on Kubernetes


    To deploy the mongodb-replicaset Helm chart on Kubernetes using Pulumi, you will create a Pulumi program in TypeScript. This program will use the @pulumi/kubernetes package to interact with your Kubernetes cluster.

    Below, I will provide a step-by-step guide that will walk you through the process of creating a Pulumi stack in TypeScript that deploys the mongodb-replicaset Helm chart.


    1. A configured Kubernetes cluster where you can deploy the Helm chart.
    2. The kubectl command-line tool connected to your cluster.
    3. Pulumi CLI installed on your local machine.
    4. Node.js installed on your local machine to run TypeScript programs.

    Step 1: Set up your project

    Initialize a new Pulumi project on your local machine by running pulumi new typescript in your terminal. This will create a new directory with a template TypeScript project.

    Step 2: Install the necessary dependencies

    You need to install the @pulumi/kubernetes package, which allows you to interact with your Kubernetes cluster from your Pulumi program.

    npm install @pulumi/kubernetes

    Step 3: Write your Pulumi program

    Now let's write your Pulumi TypeScript program. Create a new file named index.ts and populate it with the following code:

    This program defines a single resource: a Helm chart for mongodb-replicaset. The Chart resource from the @pulumi/kubernetes package represents a Helm chart in code which will be deployed on your Kubernetes cluster.

    The mongodb-replicaset chart is assumed to be hosted in a Helm repository where Pulumi can fetch it. You can optionally customize the chart by specifying different parameters inside the values argument.

    import * as k8s from "@pulumi/kubernetes"; const mongoDbReplicaSet = new k8s.helm.v3.Chart("mongodb-replicaset", { // You can specify the repository that hosts the 'mongodb-replicaset' Helm chart. // If the Helm chart is already added to your Helm CLI's repository list, you // don't need to specify the `repo` argument. repo: "the-repo-where-mongodb-replicaset-is-hosted", chart: "mongodb-replicaset", // Specify the version of the Helm chart you want to deploy. version: "the-version-of-the-mongodb-replicaset-chart", // You can provide values to customize the Helm chart's default // configuration. For example, you can change the replica count, // resource requests/limits, image version, etc. values: { replicas: 3, // Add additional values as needed. }, // The namespace where you want to deploy your Helm chart. If you don't // specify a namespace, Pulumi deploys it to the default namespace. namespace: "mongodb-namespace", }); // Export the base URL for the MongoDB replica set, which can be used to connect // to MongoDB from an application in your Kubernetes cluster. The exact command // depends on the Helm chart specification. export const mongoDbUrl = mongoDbReplicaSet.getResourceProperty("v1/Service", "mongodb-replicaset", "status");

    Step 4: Deploy your Pulumi stack

    Run the following commands in your terminal to log in to the Pulumi service and deploy your stack to your Kubernetes cluster:

    pulumi login pulumi up

    These commands will compile your TypeScript program to JavaScript, prompt you to review the changes, and apply the changes to your cluster.

    Step 5: Verify the deployment

    After the deployment is successful, check that the mongodb-replicaset pods are running:

    kubectl get pods -n mongodb-namespace

    You should see a number of pods equal to the replicas value you've configured, all in a running state.

    Documentation Reference

    For further details regarding the deployment of Helm charts and management of Kubernetes resources with Pulumi, you can refer to the official Pulumi documentation:

    The code above assumes you have a basic understanding of how Helm charts are organized and the values they accept. You would typically customize the chart by altering the values passed to it, which override the default settings that the chart provides. The specific values and their possible settings will depend on the particular mongodb-replicaset Helm chart you are using.

    Please replace "the-repo-where-mongodb-replicaset-is-hosted" and "the-version-of-the-mongodb-replicaset-chart" with the actual repository URL and chart version you wish to deploy. If these values are unspecified, Helm will use the chart's default repository and the latest version.
