Deploy the matrix-synapse-admin helm chart on AWS EKS

Question

Pulumi · Accepted Answer

Deploying a Helm chart on AWS EKS using Pulumi involves several steps. You'll need to set up an EKS cluster and then use the Helm Chart resource to deploy `matrix-synapse-admin` onto the cluster. Here's a walkthrough of creating an EKS cluster and deploying a Helm chart within it.

1. **Setting up an EKS Cluster**: To begin with, we will use the `aws.eks.Cluster` resource to create a new EKS cluster. An IAM role with the necessary permissions will also be created for the EKS cluster, using `aws-iam.EKSRole`.

2. **Deploying a Helm Chart**: Once the EKS cluster is set up, you can deploy the Helm chart to the cluster using the `kubernetes.helm.v3.Chart` resource. To do this, you'll need the repository URL where the `matrix-synapse-admin` Helm chart is located and any custom configuration needed for the chart.

Here is the Pulumi TypeScript program that deploys an EKS cluster and then the `matrix-synapse-admin` Helm chart:

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";
import * as k8s from "@pulumi/kubernetes";
import * as eks from "@pulumi/eks";

// Create an EKS cluster
const cluster = new eks.Cluster("my-cluster", {
    // Specify the desired version for the Kubernetes master and nodes here
    version: "1.21",
});

// Export the clusters' kubeconfig.
export const kubeconfig = cluster.kubeconfig;

// Create a k8s provider using the above created EKS cluster.
const provider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});

// Deploy the matrix-synapse-admin helm chart using the k8s provider.
const chart = new k8s.helm.v3.Chart("matrix-synapse-admin", {
    chart: "matrix-synapse-admin",
    version: "1.0.0", // specify the exact chart version
    fetchOpts: {
        repo: "https://your-repo-url", // the URL of the Helm repo where the chart is located
    },
}, { provider });

```

This program does the following:

- Initializes a new EKS cluster with a version number.
- Generates a Kubeconfig file that you can use to access the cluster with kubectl or other compatible tools.
- Creates a Kubernetes provider that knows how to communicate with the EKS cluster.
- Deploys the `matrix-synapse-admin` Helm chart to the EKS cluster.

Please ensure you replace `"https://your-repo-url"` with the actual URL for the Helm chart repository where `matrix-synapse-admin` is hosted and specify the correct version of the Helm chart you wish to deploy.

Remember that you need to have permissions to push to this chart repo and to create resources on the AWS account you're using. Also, ensure your Pulumi CLI is logged in and configured with the desired AWS account credentials.
