1. Deploy the mariadb-persistent helm chart on Rancher


    To deploy the mariadb-persistent Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, you'll need to follow these steps:

    1. Ensure you have a Rancher Kubernetes cluster up and running.
    2. Install the @pulumi/rancher2 package, which allows Pulumi to interact with Rancher.
    3. Use the helm.v3.Chart resource from @pulumi/kubernetes to deploy the mariadb-persistent chart to your cluster.

    You'll also need to have Pulumi and the required cloud provider CLI tools installed and configured on your machine. For Rancher, this could imply having kubectl configured with the context of your Rancher Kubernetes cluster and having the appropriate permissions to deploy Helm charts.

    Below is a detailed TypeScript program that showcases how to deploy the mariadb-persistent Helm chart on a Rancher Kubernetes cluster using Pulumi.

    Firstly, if you haven't done so already, you would need to install the necessary Pulumi packages by running:

    npm install @pulumi/pulumi @pulumi/rancher2 @pulumi/kubernetes

    Here is the Pulumi program that demonstrates the necessary steps:

    import * as pulumi from '@pulumi/pulumi'; import * as rancher2 from '@pulumi/rancher2'; import * as k8s from '@pulumi/kubernetes'; // Initialize a Rancher provider instance. const rancherProvider = new rancher2.Provider('rancher', { // Provide your Rancher API endpoint, access key, and secret key here apiUrl: 'https://<RANCHER_API_ENDPOINT>', accessKey: '<RANCHER_ACCESS_KEY>', secretKey: '<RANCHER_SECRET_KEY>', }); // You must have the Rancher Kubernetes cluster created or imported in your Rancher server. const cluster = new rancher2.Cluster('my-mariadb-cluster', { // Use the name of your existing Rancher Kubernetes cluster name: 'existing-cluster-name', }); // Initialize a Kubernetes provider instance scoped to your Rancher Kubernetes cluster. const k8sProvider = new k8s.Provider('k8s-provider', { kubeconfig: cluster.kubeConfig, }, { dependsOn: [cluster] }); // Deploy the mariadb-persistent helm chart const mariadbPersistentChart = new k8s.helm.v3.Chart('mariadb-persistent', { // Specify the Helm chart repository and chart name. chart: 'mariadb', version: 'X.Y.Z', // Specify the chart version you want to deploy fetchOpts: { repo: 'https://charts.bitnami.com/bitnami', // This is the Bitnami repository where the mariadb chart can be found }, values: { // Customize your MariaDB deployment by specifying Helm values here. // For example, if you need a persistent volume, specify persistence configurations. persistence: { enabled: true, size: '8Gi', }, // You can set other values like MariaDB username, password, etc. }, }, { provider: k8sProvider }); // Ensure to pass the Kubernetes provider instance associated with your Rancher cluster. // Export the endpoint to access the deployed MariaDB instance export const mariadbEndpoint = mariadbPersistentChart.getResourceProperty('v1/Service', 'mariadb-persistent-mariadb', 'status').apply(status => status.loadBalancer.ingress[0].ip);

    This program starts by importing the necessary Pulumi libraries. It then creates a new Pulumi provider specifically for Rancher (rancher2.Provider) using your Rancher server's API endpoint and credentials. With that provider, we reference an existing Rancher Kubernetes cluster using rancher2.Cluster.

    Next, we instantiate a Kubernetes provider (k8s.Provider) that uses the kubeconfig from the Rancher cluster to connect to it. We use this provider to deploy a Helm chart named mariadb-persistent using k8s.helm.v3.Chart. Here it's important to set the chart, version, and repo parameters correctly for the MariaDB chart. The values field is where you can specify any configurations needed to customize the MariaDB deployment, such as enabling persistence and setting the size of the persistent volume.

    Finally, we export the MariaDB endpoint, which is the load balancer IP that can be used to access the MariaDB service outside the cluster. Note that you might need to adjust the chart parameters like version and values according to the specific settings required for your mariadb-persistent deployment and what your Rancher Kubernetes cluster supports.
