1. Deploy the mysql-persistent helm chart on Rancher


    To deploy the mysql-persistent Helm chart on Rancher using Pulumi, you will need to follow these steps:

    1. Set up Rancher: Ensure you have Rancher installed and running. Rancher is a Kubernetes management platform that simplifies the deployment and operation of Kubernetes.

    2. Install Pulumi: If you haven't already, install Pulumi and set up the Pulumi CLI.

    3. Configure Pulumi for Rancher: Before you can deploy to Rancher, you need to configure Pulumi to use the rancher2 provider. This involves setting up authentication to interact with your Rancher instance via its API. You can do this by providing the Rancher API URL and a bearer token.

    4. Write the Deployment Code: Define your Rancher Kubernetes cluster configuration and use the Helm class from Pulumi's @pulumi/kubernetes library to deploy the mysql-persistent chart.

    Here's how you would write the Pulumi program in TypeScript:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; import * as rancher2 from "@pulumi/rancher2"; // Initialization of Rancher2 provider with required credentials const rancherProvider = new rancher2.Provider("rancher", { // Provide the Rancher API URL apiUrl: "https://your-rancher-api-url", // Provide a Rancher bearer token with enough privileges bearerToken: "your-rancher-bearer-token", }); // Reference the Rancher Kubernetes cluster where you wish to deploy the mysql Helm chart. // Replace `rancherClusterId` with the actual Rancher cluster ID. const cluster = rancher2.getCluster({ id: "rancherClusterId", }, { provider: rancherProvider }); // Launch the `mysql-persistent` Helm chart in the Rancher Kubernetes cluster const mysqlPersistent = new k8s.helm.v3.Chart("mysql-persistent", { // Use the fetched kubeconfig from Rancher cluster kubeconfig: cluster.kubeConfig, chart: "mysql", version: "1.6.9", // specify the version of the chart to use fetchOpts: { // Specify the repo where the mysql chart can be found repo: "https://charts.bitnami.com/bitnami", }, values: { // Define your Helm chart values here // This is hypothetical and depends on the mysql Helm chart being used persistence: { enabled: true, size: "8Gi", }, root: { password: "my-secret-pw", }, }, }, { provider: rancherProvider }); // Export the URL for the mysql service export const mysqlServiceUrl = mysqlPersistent.getResourceProperty("v1/Service", "mysql-persistent-mysql", "status").apply(status => { return status.loadBalancer.ingress[0].ip || status.loadBalancer.ingress[0].hostname; });

    In the code above:

    • We initialize a rancher2.Provider with the API URL and bearer token to authenticate to the Rancher API.
    • We retrieve the Rancher cluster configuration which includes the kubeconfig needed to interact with the Kubernetes cluster managed by Rancher.
    • We create an instance of the mysql-persistent Helm chart, specifying the chart name, version, and repository. Additionally, we provide values that configure the chart to use persistent storage and set a root password.
    • We export the MySQL service URL, which allows you to access the MySQL database deployed on the cluster.

    Please replace the placeholders like https://your-rancher-api-url, your-rancher-bearer-token, and rancherClusterId with your actual Rancher instance details. The Helm chart values example provided here is hypothetical; you will need to adjust the values section according to the actual requirements of the mysql-persistent chart you're deploying.

    Once you have this code, run pulumi up to execute the deployment. This command will prompt you to review the changes and confirm them before proceeding to apply the changes to your Rancher cluster.
