1. Deploy the vault-helm-chart helm chart on Opensshift


    To deploy the vault-helm-chart on an OpenShift cluster using Pulumi, you can leverage the kubernetes package to utilize Helm Charts directly within your Pulumi program. This provides a declarative approach to managing Helm Charts in a Kubernetes cluster, including an OpenShift cluster.

    Here's how you can do it:

    1. Setup: Before starting, you need to have access to your OpenShift cluster and have kubectl configured to communicate with it.

    2. Helm Chart: Helm Charts are packages that can be deployed on Kubernetes, and vault-helm-chart is provided by HashiCorp for deploying Vault.

    3. Pulumi Kubernetes Provider: The Pulumi Kubernetes Provider allows you to write code that interacts with Kubernetes resources, including deploying Helm charts.

    Below is the TypeScript program that accomplishes the deployment of the vault-helm-chart on an OpenShift cluster using Pulumi:

    import * as k8s from "@pulumi/kubernetes"; const projectName = "vault-deployment"; // Create a Kubernetes provider instance that uses the context from the // local kubeconfig, which should be configured to connect to your OpenShift cluster. const provider = new k8s.Provider("openshift-provider", {}); // Deploy the Vault Helm chart using the kubernetes.helm.v3.Chart class. const vaultChart = new k8s.helm.v3.Chart(projectName, { // Specify the Helm chart repository and the chart name. repo: "hashicorp", chart: "vault", // Specify the version of the chart you want to deploy. version: "0.13.0", // Replace with the desired version // Provide the values for configuring the chart. // This object structure should follow the schema expected by the chart being deployed. values: { // For example, you might need to disable persistence for the Vault state, // if you are running on an OpenShift Online cluster which doesn't allow // persistent storage without requesting quota. Be aware that disabling // persistence can have significant consequences for Vault's operations. global: { openshift: true, // Set OpenShift specific configuration }, // Set any additional values as required by the 'vault-helm-chart' }, }, { provider }); // Optionally, you can export the status of the deployed chart. export const vaultStatus = vaultChart.status;

    Remember to replace the version value with the one that corresponds to the version of the Vault Helm Chart you wish to install.

    What this program does:

    1. Imports: The program begins by importing the necessary Pulumi Kubernetes package.

    2. Provider Configuration: It sets up a Kubernetes provider to interact with your designated OpenShift cluster.

    3. Helm Chart Deployment: It then defines a new Helm chart resource for deploying Vault, specifying the repository and chart name. You have control over the Helm chart version and the necessary values to configure the chart deployment according to your requirements.

    4. Exporting Status: Lastly, the program exports the deployment status of the Vault chart, which can be useful for monitoring or for provisioning other dependent resources.

    To run this Pulumi program, you will need Node.js and the Pulumi CLI installed on your machine. Once installed, you can execute the following commands inside your Pulumi project directory:

    pulumi up

    This will prompt Pulumi to perform the deployment, which you can confirm by inspecting the CLI output or by using kubectl to check the resources in your OpenShift cluster. Before running these commands, ensure that your Pulumi stack is correctly configured and that your Kubernetes context is pointed to your OpenShift cluster.

    Please note that the values you provide in the values field must align with the Vault Helm chart's expected schema and your specific OpenShift environment's requirements. You might need to customize the values object further based on your use case and the configuration options provided by the Vault Helm chart.

    For detailed information on the Vault Helm Chart and the configuration options available, refer to the official Vault Helm Chart documentation. For more information on using Pulumi with Kubernetes resources, visit the Pulumi Kubernetes Provider documentation.
