Program the cloud with Pulumi and Google Cloud

^Kubernetes

Build and deploy a GKE cluster

Pulumi supports programming against Kubernetes – Minikube, custom on-premises, or cloud-hosted custom clusters or in managed clusters such as Google GKE.

This code defines a GKE cluster with configurable settings which could be used in a module which could then be used to deploy an app to the cluster.

Get Started

Pulumi can be used on any resource covering serverless, containers, and infrastructure using JavaScript, TypeScript, Python, and Go.

// Define a GKE cluster with configurable settings
import * as gcp from "@pulumi/gcp";
import { nodeCount, nodeMachineType, password, username } from "./config";

export const k8sCluster = new gcp.container.Cluster("gke-cluster", {
    initialNodeCount: nodeCount,
    nodeVersion: "latest",
    minMasterVersion: "latest",
    masterAuth: { username, password },
    nodeConfig: {
        machineType: nodeMachineType,
        oauthScopes: [
            "https://www.googleapis.com/auth/compute",
            "https://www.googleapis.com/auth/devstorage.read_only",
            "https://www.googleapis.com/auth/logging.write",
            "https://www.googleapis.com/auth/monitoring"
        ],
    },
});
    

^Kubernetes

Build and deploy Kubernetes apps to GKE

Pulumi supports deploying apps and services to Kubernetes clusters such as GKE.

This code makes use of our previously defined GKE cluster and deploys an nginx canary onto the cluster with 1 replica.

Get Started

Pulumi can be used on any resource covering serverless, containers, and infrastructure using JavaScript, TypeScript, Python, and Go.

// Deploy an nginx canary to GKE
import * as k8s from "@pulumi/kubernetes";
import * as pulumi from "@pulumi/pulumi";
import { k8sProvider, k8sConfig } from "./cluster";

// Create a canary deployment to test that this cluster works.
const name = `${pulumi.getProject()}-${pulumi.getStack()}`;
const canaryLabels = { app: `canary-${name}` };
const canary = new k8s.apps.v1beta1.Deployment("canary", {
    spec: {
        selector: { matchLabels: canaryLabels },
        replicas: 1,
        template: {
            metadata: { labels: canaryLabels },
            spec: { containers: [{ name, image: "nginx" }] },
        },
    },
}, { provider: k8sProvider });

// Export the Kubeconfig so that clients can easily access our cluster.
export let kubeConfig = k8sConfig;

        

^{Infrastructure}

Creating a Simple Web Server

Pulumi gives you a way to express infrastructure configuration using your favorite programming language.

This code uses TypeScript on Node.js to define the necessary environment, defines a very simple web server, and then creates the instance, before exporting the IP and Hostname.

Get Started

Pulumi can be used on any resource covering serverless, containers, and infrastructure using JavaScript, TypeScript, Python, and Go.

const gcp = require("@pulumi/gcp");

const computeNetwork = new gcp.compute.Network("network", {
    autoCreateSubnetworks: true,
});

const computeFirewall = new gcp.compute.Firewall("firewall", {
    network: computeNetwork.selfLink,
    allows: [{
        protocol: "tcp",
        ports: [ "22", "80" ],
    }],
});

// Create a simple web server
const startupScript = `#!/bin/bash
echo "Hello, World!" > index.html
nohup python -m SimpleHTTPServer 80 &`;

const computeInstance = new gcp.compute.Instance("instance", {
    machineType: "f1-micro",
    metadataStartupScript: startupScript,
    bootDisk: {
        initializeParams: {
            image: "debian-cloud/debian-8",
        },
    },
    networkInterfaces: [{
        network: computeNetwork.id,
        accessConfigs: [{}], // must be empty 
    }],
    serviceAccount: {
      scopes: ["https://www.googleapis.com/auth/cloud-platform"],
    },
}, { dependsOn: [computeFirewall] });

exports.instanceName = computeInstance.name;
exports.instanceIP = computeInstance.networkInterfaces.apply(ni => ni[0].accessConfigs[0].natIp);
        

^Serverless

Creating a Google Cloud Function

With Pulumi, you can combine infrastructure definitions and application code in one program. The @pulumi/cloud-gcp library is a set of Pulumi components that provide a higher-level abstraction over Azure. You can use this library and define application code at the same time as the infrastructure it depends on.

This example shows how to create a simple Google Cloud Function that returns a message when invoked.

Get Started

Pulumi can be used on any resource covering serverless, containers, and infrastructure using JavaScript, TypeScript, Python, and Go.

// Create a simple Function
            import * as gcpFunction from "./gcpFunction";
            
            let greetingFunction = new gcpFunction.HttpFunction("greeting", (req, res) => {
                res.send(`Greetings from ${req.body.name || 'Google Cloud Functions'}!`);
            });
            
            export let url = greetingFunction.httpsTriggerUrl;
