Deploy the mysql-ob helm chart on Kubernetes
TypeScriptTo deploy the MySQL Operator-based (mysql-ob) Helm chart on a Kubernetes cluster using Pulumi, we will use a Pulumi Kubernetes provider. This provider allows us to interact with Kubernetes resources within our Pulumi program. Specifically, we will use the
Chart
resource from@pulumi/kubernetes
to deploy the Helm chart.Here is how we can accomplish this:
-
Set Up Your Kubernetes Cluster: Ensure you have a Kubernetes cluster running and
kubectl
configured to connect to your cluster. Your Pulumi program will usekubectl
's current context to deploy resources, so it needs to be correctly set up to target the desired cluster. -
Choose the Right Helm Chart: We need the name of the Helm chart (mysql-ob) and optionally, the repository if it's not part of the stable repository that Helm uses by default.
-
Write the Pulumi Program: With that information, we can write a Pulumi TypeScript program to deploy the chart. The program will define a
Chart
resource that specifies the chart to deploy, as well as any necessary configuration values for it. -
Deploy with Pulumi: Once the Pulumi program is written, use the Pulumi CLI to deploy the Helm chart to the Kubernetes cluster.
Below is the Pulumi program written in TypeScript that you can use to deploy the mysql-ob Helm chart. The
Chart
resource is the primary resource used to deploy Helm charts. It needs to be imported from the@pulumi/kubernetes/helm/v3
package. If the mysql-ob chart requires any specific configuration values, you'll need to provide them in thevalues
parameter.import * as k8s from "@pulumi/kubernetes"; // Define the MySQL Operator-based Helm chart. // Replace `repo` with the correct Helm repository URL if it's not a commonly known repo. // Also, replace `version` with the version number of the chart if you wish to use a specific version. const mysqlChart = new k8s.helm.v3.Chart("mysql-ob", { chart: "mysql-ob", version: "1.0.0", // Assuming version 1.0.0, replace with the actual chart version you want to deploy. fetchOpts: { repo: "https://charts.bitnami.com/bitnami", // Example repository, replace with the actual repository of mysql-ob if different. }, // If the mysql-ob Helm chart requires any values to be set, define them here. // For example: // values: { // mysqlUser: "admin", // mysqlPassword: "password", // }, }); // Export any stack outputs, like the MySQL Service endpoint if needed export const mysqlServiceEndpoint = mysqlChart.getResourceProperty( "v1/Service", // Replace with the actual API version and kind for mysql-ob service. "mysql-ob-service-name", // Replace with the actual name of the MySQL service deployed by the Helm chart. "status" ).apply(status => status.loadBalancer.ingress[0].ip); // Accessing the load balancer IP, might be different for your chart/setup.
This program defines a Helm chart resource by specifying the chart name and version. It points to a Helm repository where the chart is located, and then deploys the chart to the Kubernetes cluster associated with the current context set in
kubectl
. Thevalues
object is commented out; you will need to uncomment it and provide the appropriate values based on the mysql-ob chart's requirements.After writing this program, save it in a
.ts
file and use the Pulumi command line to create a new stack and deploy your resources.Run the following commands:
pulumi stack init
to create a new stack.pulumi up
to preview and deploy the changes.
Remember to check the Pulumi documentation for the
Chart
resource if you need more information on customization and configuration options.Please replace placeholders and commented configurations with actual values that are appropriate for your use case. If the Helm chart you're trying to deploy is not hosted on a public Helm repository, or if it requires authentication, you will need to add the necessary fields to access it (like
username
andpassword
infetchOpts
).-
