Deploy the gloo-mesh helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the Gloo Mesh Helm chart on Kubernetes using Pulumi, you will need to perform the following steps:

1. Set up your Kubernetes cluster where you want to deploy Gloo Mesh.
2. Install the Pulumi CLI and authenticate with your Kubernetes cluster.
3. Write a Pulumi TypeScript program that uses the `@pulumi/kubernetes` package to deploy Helm charts.
4. Deploy the Gloo Mesh Helm chart using the `Chart` resource from the Pulumi Kubernetes provider.

The following is a Pulumi TypeScript program that deploys the Gloo Mesh Helm chart. This program assumes that you've already configured your local environment to communicate with your Kubernetes cluster, for example by running `kubectl` commands. Before running this program, also ensure you have access to the Helm chart for Gloo Mesh, typically by adding the Gloo Mesh Helm repository.

Here's the Pulumi program that deploys the Gloo Mesh Helm chart:

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

const glooMeshNamespace = new k8s.core.v1.Namespace("gloo-mesh-namespace", {
    metadata: {
        name: "gloo-mesh",
    },
});

const glooMeshChart = new k8s.helm.v3.Chart("gloo-mesh-chart", {
    chart: "gloo-mesh",
    version: "1.1.0", // Substitute with the current version of Gloo Mesh Helm chart you wish to deploy
    namespace: glooMeshNamespace.metadata.name,
    // If the chart is from a custom Helm repo, uncomment the repositoryOpts line and add the custom Helm repo URL
    // repositoryOpts: {
    //     repo: "https://helm.gloo-mesh.io",
    // },
    // If you want to override any default values, you can add the 'values' property like this:
    // values: {
    //     someValue: "override-value",
    // },
}, { dependsOn: glooMeshNamespace });

export const glooMeshChartName = glooMeshChart.metadata.name;
```

**Explanation**:

- We first import the Pulumi Kubernetes SDK to work with Kubernetes resources.
- We create a namespace for Gloo Mesh called `gloo-mesh` using the `Namespace` resource. This is done so that all Gloo Mesh-related Kubernetes resources are organized in a dedicated namespace.
- We then create a new instance of `Chart`, a Pulumi resource representing a Helm chart deployment.
- We provide the `gloo-mesh` chart name and specify the version you want to deploy. The version provided should be the version of the Gloo Mesh you wish to deploy; please ensure to use the correct version number. If you're pulling from a custom Helm repo other than the default stable repo, you would need to specify the `repositoryOpts` property with the Helm repo URL.
- (optional) If there are specific configurations you want to pass to the Helm chart, you can set them using the `values` property. This will override the default values set in the Helm chart.
- The `dependsOn` option ensures that the Helm chart deployment occurs after the namespace is created.

**Note**: Before running the Pulumi program, you must have Pulumi CLI installed and have your Kubernetes cluster's configuration set up correctly to allow Pulumi to deploy to it (usually done by configuring `kubectl`).

After writing this code into a file (e.g., `index.ts`), you can run `pulumi up` in the same directory to deploy Gloo Mesh onto your Kubernetes cluster.

If you want to interact with Pulumi in an automated fashion (for example, in a CI/CD pipeline), you might also include programmatic login and selection of the Pulumi stack in your automation scripts.

To remove the deployment, you can run `pulumi destroy`, which will tear down all resources created by the program.
