Deploy the matrix-synapse-admin helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the Matrix Synapse Admin Helm chart on OpenShift using Pulumi, we will utilize the kubernetes.helm.v3.Chart resource from Pulumi’s Kubernetes provider. The Helm chart resource allows you to deploy Helm charts in a Kubernetes cluster in the same way you would with the helm command-line tool.

Below is the TypeScript program to deploy the Matrix Synapse Admin chart to your OpenShift cluster. You will need to have Pulumi installed and configured to use your Kubernetes cluster, whether it's an OpenShift cluster, or any other Kubernetes cluster.

First, we will need to import the necessary modules and create a new instance of the Helm chart.

Here is what each part of the code is doing:

We import the @pulumi/kubernetes library which is necessary to interact with Kubernetes clusters using Pulumi.
We instantiate a Chart resource, providing the chart name (matrix-synapse-admin) and configuration options. This includes specifying the Helm repository where the chart can be found, the version of the chart, and any custom configurations that may be needed in the values object.

Make sure to replace <your-namespace> with the namespace you want the chart to be deployed to, and <chart-version> with the specific version of the matrix-synapse-admin chart you wish to use. If you have any specific configuration parameters that you need to pass to the chart to customize it, you can do so inside the values property. If the Helm chart you are using requires it and you are storing custom configurations in a separate YAML file, you can pull in the values from that file and pass them to the values property.

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

// Assuming you have OpenShift or any other Kubernetes cluster context already set,
// the following code will deploy the Matrix Synapse Admin Helm chart.

const matrixSynapseAdminChart = new k8s.helm.v3.Chart("matrix-synapse-admin", {
    // Replace with the actual repository where the Helm chart is located
    repo: "your-repo",
    chart: "matrix-synapse-admin",
    version: "<chart-version>",
    // Ensure you've specified the namespace where you want to deploy the chart
    namespace: "<your-namespace>",
    // Custom values for the Helm chart can be specified in the 'values' property
    values: {
        // Replace with key-value pairs specific to your chart requirements
        key1: "value1",
        key2: "value2",
        // Add more configuration parameters as required
    },
    // If your chart requires specific transformations, you can specify them in 'transformations' property
});

// Export a relevant endpoint from your deployment if applicable
// For example, if the Helm chart creates a LoadBalancer service for access
export const serviceEndpoint = matrixSynapseAdminChart.getResourceProperty("v1/Service", "<service-name>", "status").apply(status => status.loadBalancer.ingress[0].hostname);

After you've added the correct repository and customized the values to your liking, you can deploy the Helm chart by running pulumi up.

This will start the deployment process on the currently configured Kubernetes cluster. The export line at the end is optional; it's used to export any output you wish to view or use after deployment, such as the endpoint of a LoadBalancer service created by the Helm chart.

Remember to have kubectl configured to access your OpenShift cluster. Pulumi uses the current context of kubectl to interact with Kubernetes clusters. If you have multiple clusters, make sure you set the context to point to your OpenShift cluster before running the Pulumi program.
