1. Deploy the mysql-persistent helm chart on Opensshift

    TypeScript

    To deploy the mysql-persistent Helm chart on OpenShift using Pulumi, you'll utilize the kubernetes.helm.v3.Chart class from the Pulumi Kubernetes provider. This class allows you to specify a Helm chart to be deployed along with its configuration values.

    Here's a step-by-step breakdown of the program:

    1. Import Pulumi Kubernetes Package: You need to import the Pulumi Kubernetes package into your TypeScript program to work with Kubernetes resources.

    2. Create a Helm Chart Resource: The Chart class represents a Helm Chart installation. Initialize a new Chart and specify the mysql-persistent Helm chart, including any necessary configuration values required by the chart.

    3. Specify Chart Repository and Version: Provide the name of the Helm chart, repository details, and version (if required).

    4. Set Configuration Values: Helm charts can require (or optionally accept) configuration for various parameters. These values can be set using the values argument.

    5. Use the Right Namespace: Ensure that your Helm chart is deployed to the intended Kubernetes namespace.

    Before running this program, make sure you have Pulumi and the required Kubernetes configuration set up to target your OpenShift cluster. Now let's look at the program:

    import * as k8s from "@pulumi/kubernetes"; // Create a new instance of the 'mysql-persistent' Helm chart in the 'default' namespace. // Replace '<CHART VERSION>' with the specific version you want to deploy, if necessary. // If the chart doesn't come from the default Helm repo, also provide the 'repo' property. const mysqlPersistentChart = new k8s.helm.v3.Chart("mysql-persistent", { chart: "mysql-persistent", version: "<CHART VERSION>", // specify the chart version here, if required // Uncomment the following line and set your custom Helm repo URL if needed. // fetchOpts: { repo: "https://charts.your-organization.com/" }, values: { // Set your required chart values here. For example: mysqlUser: "user", mysqlPassword: "password", mysqlRootPassword: "rootpassword", mysqlDatabase: "mydatabase" // Ensure you set any other values required by the 'mysql-persistent' chart. }, // It's essential to set the namespace for the chart if it's different from 'default'. namespace: "default", }, { provider: myOpenShiftProvider }); // specify your OpenShift provider // Export the MySQL Service endpoint export const mysqlService = mysqlPersistentChart.getResourceProperty("v1/Service", "mysql-persistent", "status");

    In the above program:

    • Replace <CHART VERSION> with the actual version number of the chart you are deploying.
    • If your chart requires a custom repo or other fetchOpts, uncomment and configure the fetchOpts property accordingly.
    • The values field allows you to specify values that will be used when deploying the Helm chart. These should match the expected values for the mysql-persistent Helm chart. Be sure to replace example values with your real configuration.
    • The namespace field specifies the target Kubernetes namespace where the chart should be deployed.
    • For the myOpenShiftProvider, you should have a Kubernetes provider instance configured to target your OpenShift cluster.

    This code should get you started on deploying the mysql-persistent Helm chart to your OpenShift cluster using Pulumi. Make sure you review the configuration options of the mysql-persistent Helm chart to fully understand what values it accepts and requires.

    Finally, you can run your Pulumi program using the Pulumi CLI:

    pulumi up

    This command will perform a preview of the changes and then prompt you to proceed with the actual deployment/update. Once confirmed, Pulumi will carry out the deployment to your OpenShift cluster.
