1. Deploy the velero-backup helm chart on Kubernetes


    To deploy the velero-backup Helm chart on a Kubernetes cluster using Pulumi, we will use the @pulumi/kubernetes package, which provides the necessary interfaces for deploying resources to a Kubernetes cluster. The specific resource we'll use is Chart from kubernetes.helm.sh/v3, which represents a Helm chart.

    Here is a step-by-step guide to deploying the velero-backup Helm chart using Pulumi with TypeScript:

    1. Import the necessary Pulumi Kubernetes libraries: We need to import the Kubernetes package to create a Helm chart resource.

    2. Create a Pulumi project: If you haven't already created a Pulumi project, you need to do so. You can create a new Pulumi project using the command pulumi new kubernetes-typescript.

    3. Choose the right namespace: Helm charts can be deployed into specific namespaces within Kubernetes. If you have a namespace where you want to deploy the Helm chart, you need to specify it. Otherwise, you can use the default namespace or create a new one.

    4. Deploy the Helm chart using the Chart resource: The Chart resource in Pulumi allows you to deploy a Helm chart by specifying its name, version, and any values you want to override.

    5. Configure the settings for the velero-backup chart: To customize the installation, you can adjust the values field with the settings that the velero-backup chart accepts.

    6. Running Pulumi up: Once your Pulumi code is written, you can deploy the resources to your Kubernetes cluster by running pulumi up in your terminal.

    Here is a TypeScript program that demonstrates these steps:

    import * as k8s from '@pulumi/kubernetes'; // Create a Helm chart resource using the kubernetes.helm.v3.Chart class. // This will deploy the velero-backup Helm chart to the Kubernetes cluster. const veleroBackupChart = new k8s.helm.v3.Chart('velero-backup', { // Specify the chart repository URL and name of the Helm chart. chart: 'velero', // Note: Replace the '<CHART-VERSION>' placeholder with the version of the Velero Helm chart you want to deploy. version: '<CHART-VERSION>', fetchOpts: { repo: 'https://vmware-tanzu.github.io/helm-charts', }, // Provide any custom values to the Helm chart. For Velero, you usually need to specify // the backup storage location, provider credentials, etc. values: { // These are example values. You'll need to provide the actual configuration // that is applicable to your environment. configuration: { provider: 'aws', backupStorageLocation: { bucket: '<BUCKET-NAME>', prefix: 'velero-backup', }, }, // Specify credentials for the cloud provider. // This should be replaced with the actual secret that contains provider credentials. credentials: { secretContents: { cloud: ` [default] aws_access_key_id=<AWS-ACCESS-KEY-ID> aws_secret_access_key=<AWS-SECRET-ACCESS-KEY> `, }, }, // Enable or disable features as needed. snapshotsEnabled: false, }, // Optional: Specify the namespace where the chart should be installed. If not provided, it will be installed in the default namespace. namespace: 'velero', }); // To access the resources, you might want to export relevant information, such as the namespace used. export const veleroNamespace = veleroBackupChart.namespace;

    Replace <CHART-VERSION>, <BUCKET-NAME>, <AWS-ACCESS-KEY-ID>, and <AWS-SECRET-ACCESS-KEY> with actual values corresponding to your setup. These values are used to configure the chart with your cloud provider details and backup storage location.

    Notes on the program:

    • @pulumi/kubernetes: This package includes the APIs needed to interact with Kubernetes within Pulumi programs.
    • k8s.helm.v3.Chart: Represents the Helm chart to be deployed.
    • chart: Specifies the name of the Helm chart.
    • version: Specifies the version of the Helm chart to deploy.
    • fetchOpts: Contains options such as the Helm repository URL where the chart can be fetched.
    • values: This is used to provide configuration values for the Helm chart that override the default settings. You typically need to tailor this to your specific use case.
    • export: This is used to export any important information from the deployment. In this case, we export the namespace where the Velero chart is installed.

    Please make sure you have Pulumi installed and configured with the appropriate Kubernetes context with permissions to deploy resources into your cluster. After configuring Pulumi with the correct context, you can run the program by navigating to the directory containing your index.ts file and executing the pulumi up command. This will initiate the deployment process of the velero-backup Helm chart into your Kubernetes cluster.
