Deploy the matrix-synapse-admin helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the Matrix Synapse Admin Helm chart on a Kubernetes cluster using Pulumi, you would typically follow these steps:

Set up: Ensure you have Pulumi installed and configured with your desired cloud provider.
Kubernetes Cluster: Have an existing Kubernetes cluster or create one using Pulumi. You must have kubectl configured to communicate with your cluster.
Helm Chart: Ensure that Helm is installed and that you have added the repository hosting the Matrix Synapse Admin chart.
Pulumi Kubernetes Package: Utilize the Pulumi Kubernetes package which enables you to deploy Helm charts.

Below is a Pulumi program in TypeScript that exemplifies how to deploy the Matrix Synapse Admin Helm chart to an existing Kubernetes cluster. The program assumes you have an existing Kubernetes cluster and appropriate kubeconfig file to interact with the cluster. It uses the kubernetes.helm.v3.Chart class to deploy the Helm chart.

First, make sure you have everything set up correctly:

Install Pulumi and set up the Pulumi CLI.
Configure kubectl with access to your Kubernetes cluster.
Make sure you have Node.js and npm installed to run the Pulumi program.
Create a new directory for your Pulumi project, if you haven’t already.

Here's a step-by-step guide followed by the program:

Step-by-step Guide

Import Pulumi Kubernetes Package: The Pulumi Kubernetes package is a set of Node.js (TypeScript) libraries that make it easy to describe Kubernetes resources.
Create an Instance of Chart: The Chart resource is a component resource that installs a Helm chart into a Kubernetes cluster.
Configure the Matrix Synapse Admin Chart:
- Specify the chart name, version, and values according to your requirements.
- You can customize the Helm release by providing configuration values which override the defaults set by the Helm chart.
Deploy: Run pulumi up to deploy the Helm chart to your cluster.

Pulumi Program

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

const matrixSynapseAdminChart = new k8s.helm.v3.Chart("matrix-synapse-admin", {
    // Specify the chart repository and name.
    chart: "matrix-synapse-admin",
    version: "<CHART_VERSION>", // Replace with the specific chart version
    fetchOpts:{
        repo: "https://YOUR_HELM_CHART_REPOSITORY", // Replace with actual Helm chart repository
    },

    // Here you can provide a custom `values.yaml` or configure the values programmatically.
    // Supplying these values is optional; if omitted, the default chart values will be used.
    // Below is a placeholder structure to indicate where you would put your configuration.
    values: {
        // Example configuration (update with actual values or structure):
        adminApiUrl: "http://<SYNAPSE_SERVER_ADDRESS>:<PORT>",
        // Other configuration values specific to the Matrix Synapse Admin chart...
        // Refer to the chart's documentation for supported values.
    },
});

// Export the URL for the admin frontend (which you would get from the service endpoint or ingress, if configured).
// Change 'service' to 'ingress' or the relevant resource type if needed.
export const adminFrontendUrl = matrixSynapseAdminChart.getResourceProperty(
    "v1/Service", "matrix-synapse-admin-frontend", "status"
).apply(status => status.loadBalancer.ingress[0].hostname);

Replace <CHART_VERSION> with the specific version of the chart you want to install, and YOUR_HELM_CHART_REPOSITORY with the URL to the Helm chart repository containing the Matrix Synapse Admin chart.

Running Your Program

Once you have this code in a file (e.g., index.ts), you can execute the Pulumi program with the following commands:

$ pulumi stack init dev                 # Initialize a new Pulumi development stack
$ pulumi up                             # Preview and deploy changes

Clean Up

After you’re done, you can destroy all resources created by your Pulumi program with the following command:

$ pulumi destroy                       # Tear down all resources

Remember to check the Helm chart's documentation for the configuration values available and customize the values field accordingly. The adminApiUrl and other values will need to be set based on how you've deployed Matrix Synapse and the way the Helm chart is set up. The specifics can be found in the Helm chart's values.yaml file or documentation.

Lastly, the export at the end of the program is used to output any resulting service URLs or other important information that could be of use, such as the address to access your deployed Matrix Synapse Admin frontend. Adjust the exported properties to match the output of your specific Helm chart and deployment details.
