How do I deploy a Kubernetes namespace with Pulumi?

In this tutorial, we will deploy a Kubernetes namespace using Pulumi. A namespace in Kubernetes is a way to divide cluster resources between multiple users. Namespaces provide a scope for names, which helps to avoid name collisions and manage resources more efficiently.

Here is the TypeScript code to create a Kubernetes namespace using Pulumi:

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

// Define the namespace metadata
const namespaceMetadata = {
    name: "my-namespace",
    labels: {
        "environment": "dev",
    },
};

// Create a new namespace
const myNamespace = new k8s.core.v1.Namespace("my-namespace", {
    metadata: namespaceMetadata,
});

// Export the namespace name
export const namespaceName = myNamespace.metadata.name;

Key Points:

• We import the necessary Pulumi and Kubernetes libraries.
• We define metadata for the namespace, including its name and labels.
• We create the namespace using k8s.core.v1.Namespace.
• We export the namespace name to make it accessible outside the program.

Summary:

In this tutorial, we deployed a Kubernetes namespace using Pulumi. We defined the namespace metadata, created the namespace, and exported its name. This approach helps manage Kubernetes resources programmatically using Pulumi, providing a more organized and scalable way to handle infrastructure as code.
