1. Deploy the mongodb-backup-aws helm chart on Kubernetes


    To deploy the mongodb-backup-aws Helm chart on Kubernetes using Pulumi, we'll walk through the following steps:

    1. Set Up Kubernetes Cluster: Ensure you have a Kubernetes cluster running. For AWS, this is typically an Amazon EKS cluster.
    2. Install Pulumi: Make sure you have Pulumi installed and configured for use with your AWS account and Kubernetes.
    3. Create a New Pulumi Project: A Pulumi project will organize your infrastructure as code.
    4. Write the Pulumi Code: We'll create the necessary code to deploy the Helm chart.
    5. Deploy: Run pulumi up to deploy the Helm chart to your cluster.

    Below I'll write a TypeScript program using Pulumi to deploy the mongodb-backup-aws Helm chart:

    import * as k8s from "@pulumi/kubernetes"; // This code assumes that a Kubernetes cluster is already provisioned and Pulumi is configured // with the kubeconfig file pointing to the respective cluster. // Create an instance of the k8s Provider. This uses the current context from your kubeconfig. const provider = new k8s.Provider("k8s-provider", {}); // Deploy the mongodb-backup-aws Helm chart using the k8s.helm.v3.Chart class. const mongoDbBackupChart = new k8s.helm.v3.Chart( "mongodb-backup-chart", { // The chart for mongodb-backup-aws can be found in a Helm repo, you need to specify the repo URL here. // If it's a custom chart, the path can be given as a relative path in the filesystem. repo: "helm-repo-url", // Replace with the URL of the Helm repository. chart: "mongodb-backup-aws", // Specify the version of the Helm chart you wish to deploy. version: "chart-version", // Replace with the chart version you wish to use. // Pass in values to configure the Helm chart. values: { // Values are typically structured as an object, with keys representing the different configurable options of the chart. // Here you will need to replace it with the actual values necessary for the 'mongodb-backup-aws' Helm chart. // Example configuration (you'll need to use actual values appropriate for your deployment): // backupSchedule: "0 2 * * *", // aws: { // region: "us-west-2", // s3: { // bucket: "my-mongodb-backup-bucket" // } // } } }, { provider: provider } // Pass the provider to the chart to use the right context. ); // Export the resources. export const helmReleaseName = mongoDbBackupChart.getResourceProperty( "v1/Service", "mongodb-backup-service", "metadata", "name" ); // Run pulumi up to deploy the Helm Chart to the Kubernetes cluster, // and check the exported helmReleaseName in the outputs.


    • Provider Setup: The provider instance represents the configured Kubernetes provider. It should be pointing to an existing Kubernetes cluster.
    • Helm Chart Deployment: The mongoDbBackupChart is a Pulumi resource that represents the MongoDB backup Helm chart. Ensure that you replace "helm-repo-url" with the URL of the Helm repository where the mongodb-backup-aws chart is hosted and specify the correct version. The values object must be populated with the necessary configuration for the chart, which typically includes AWS credentials, S3 bucket details, the backup schedule, and any other pertinent settings that the chart requires.
    • Exported Output: The helmReleaseName variable is exported, which allows you to see the Kubernetes Service name created by the Helm chart once it has been deployed. This is helpful for verifying that your deployment has succeeded.

    To deploy this, you would execute pulumi up in the command line within the directory of this Pulumi project. Pulumi would then perform the deployment to your existing Kubernetes cluster.

    Note: Before running pulumi up, ensure you have access to your Kubernetes cluster and the AWS account where the S3 bucket is located, as the Helm chart will likely interact with AWS services. The Pulumi program implicitly uses your configured kubeconfig and AWS credentials.

    Remember, the actual Helm chart parameters (values) will depend on the specific mongodb-backup-aws Helm chart you are using. You should refer to the official documentation of that Helm chart for the right configuration options.
