Deploy the mautrix-discord helm chart on Opensshift

Question

Pulumi · Accepted Answer

Deploying a Helm chart on OpenShift using Pulumi involves several steps. You'll first need to set up your Pulumi environment for Kubernetes and OpenShift. Then, you can create a Helm chart deployment using Pulumi's Kubernetes provider.

Below is a Pulumi TypeScript program that demonstrates how to deploy a Helm chart onto an OpenShift cluster. This example assumes you have an OpenShift cluster running and kubectl is configured to connect to it.

First, you must install the necessary Pulumi packages. For this, the @pulumi/kubernetes package is required. You can install it using npm (Node.js package manager):

npm install @pulumi/pulumi @pulumi/kubernetes

Once the packages are installed, you can write your Pulumi program in TypeScript to deploy the mautrix-discord Helm chart. Please replace <your-helm-chart-repo> with the actual Helm chart repository URL where the mautrix-discord chart is located, and <chart-version> with the chart version you wish to deploy.

Here is a program that demonstrates how to accomplish this:

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

// Create a Kubernetes provider instance for OpenShift
const openshiftProvider = new k8s.Provider("openshiftProvider", {
    // Assuming your kubeconfig file is set up to connect to your OpenShift cluster
    // Keep in mind this is just an example, make sure to configure accordingly
    kubeconfig: process.env.KUBECONFIG,
});

// Define the Helm chart release for mautrix-discord
const mautrixDiscordRelease = new k8s.helm.v3.Chart("mautrix-discord", {
    repo: "<your-helm-chart-repo>",
    chart: "mautrix-discord",
    version: "<chart-version>",
    // Specify the values here according to the mautrix-discord chart requirements
    values: {
        // Your configuration values go here
    },
    // Namespace where the chart will be installed
    namespace: "mautrix-discord",
}, { provider: openshiftProvider });

// Export the base URL where mautrix-discord will be available
export const baseURL = mautrixDiscordRelease.getResourceProperty(
    "v1/Service", "mautrix-discord", "status"
).apply(status => status.loadBalancer.ingress[0].hostname);

Make sure to replace the placeholder values with the actual Helm repository and chart version for mautrix-discord.

Explanation of the code:

We import the Kubernetes package from Pulumi to work with Kubernetes resources.
We create an instance of a Kubernetes provider configured to manage resources in your OpenShift cluster. This requires access to a kubeconfig file, which we assume is available in your environment (process.env.KUBECONFIG).
We define a new Helm chart resource. This Pulumi Kubernetes resource uses Helm to deploy the mautrix-discord chart.
The repo is the Helm repository URL where the chart is hosted, chart is the name of the chart to deploy, and version specifies the chart version to deploy.
The values field is an object where you specify configuration values required by the mautrix-discord Helm chart.
We specify a namespace where the chart will be installed. In this case, it's "mautrix-discord". If this namespace does not already exist, you should create it manually or add code to create it as part of your Pulumi program.
The provider option is used to specify that this chart should be deployed using the OpenShift provider we defined earlier.
Finally, we export a baseURL which is a computed value that contains the hostname where the mautrix-discord service can be accessed once it's deployed. Note that this depends on OpenShift's specific way of exposing services, which typically involves a route or an ingress. Please modify this export as needed for your specific OpenShift configuration, as this example assumes a LoadBalancer service type.

Please ensure all your authentication credentials are correctly set up and that you have permissions to deploy Helm charts on the OpenShift cluster. You can then run the program with pulumi up. This command will provision the resources as defined in the TypeScript program after you confirm the deployment.
