Deploy the mysql8 helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the MySQL 8 Helm chart on an OpenShift cluster using Pulumi, you'll use the `kubernetes` package to interact with your Kubernetes resources and Helm charts.

Below, you will find a detailed Pulumi TypeScript program that creates a new Helm chart deployment for MySQL 8 on an OpenShift cluster. This assumes that you already have access to an OpenShift cluster and have configured your Pulumi environment to interact with your Kubernetes cluster.

The program performs the following actions:

1. It imports the necessary modules from the Pulumi Kubernetes package.
2. It defines a new Helm chart resource, specifying the MySQL 8 chart and its settings.
3. It sets the appropriate namespace for deploying the chart (adjust as needed).

Before running the Pulumi program, ensure that you have:

- Installed Pulumi CLI and set up your Pulumi account.
- Installed and configured `kubectl` to communicate with your OpenShift cluster.
- Logged into your OpenShift cluster using `oc login` or configured a Kubernetes context that Pulumi can use.

Here's the detailed Pulumi program:

```typescript
import * as k8s from "@pulumi/kubernetes";

// Create a new MySQL Helm chart instance, specifying the version and repository.
const mysqlChart = new k8s.helm.v3.Chart("mysql-release", {
    chart: "mysql",
    version: "8.8.25",  // Specify the chart version you desire
    repositoryOpts: {
        repo: "https://charts.bitnami.com/bitnami",
    },
    values: {
        // Specify Helm values here if you need to customize your MySQL installation
        // For example:
        // auth: {
        //     rootPassword: "my-secret-pw",
        //     username: "my-user",
        //     password: "my-user-pw",
        //     database: "my-database"
        // },
        // volumePermissions: {
        //     enabled: true
        // }
        // You can find default Helm chart values here: https://github.com/bitnami/charts/blob/master/bitnami/mysql/values.yaml
    },
    namespace: "mysql-namespace", // Set the namespace where you want to deploy the chart
}, { provider: yourK8sProviderName }); // Make sure to provide your Kubernetes provider if needed

export const mysqlStatus = mysqlChart.status; // Export the status of the Helm release
```

Replace `yourK8sProviderName` with the name of your Kubernetes provider if you are using a specific one (e.g., if managing multiple clusters).

The `values` object within the Helm chart instantiation allows you to customize the deployment settings of MySQL. These settings might include authentication configurations, storage options, or any other customizations provided by the Helm chart. The values provided here are placeholders, and you should adjust them according to your requirements.

To run this program, save it to a file with a `.ts` extension, for example `deployMysql.ts`. After that, follow these steps:

1. Initialize a new Pulumi stack if you haven't already done so.
   ```
   pulumi stack init dev
   ```
2. Select the desired Kubernetes context that points to your OpenShift cluster if not already selected:
   ```
   pulumi config set kubernetes:context <context-name>
   ```
3. Run the following Pulumi command to preview and deploy your changes:
   ```
   pulumi up
   ```

When you run `pulumi up`, Pulumi will coordinate with Helm and your OpenShift cluster to deploy MySQL 8 as specified. If you need to make changes to your deployment, you can adjust the `values` in the program and rerun `pulumi up`.
