Pulumi Has a Free API: Infrastructure as Code in Real Programming Languages

#infrastructure #devops #typescript #cloud

Why Pulumi

Pulumi lets you define infrastructure in TypeScript, Python, Go, C#, or Java — real languages with real IDEs, real testing, and real package managers. No HCL, no YAML.

Install

brew install pulumi

Create AWS Resources in TypeScript

import * as pulumi from '@pulumi/pulumi';
import * as aws from '@pulumi/aws';

const bucket = new aws.s3.Bucket('my-bucket', {
  website: {
    indexDocument: 'index.html',
  },
});

const instance = new aws.ec2.Instance('web', {
  instanceType: 't3.micro',
  ami: 'ami-0c55b159cbfafe1f0',
  tags: { Name: 'web-server' },
});

export const bucketUrl = bucket.websiteEndpoint;
export const publicIp = instance.publicIp;

pulumi up       # Deploy
pulumi preview  # Preview changes
pulumi destroy  # Tear down

Kubernetes in Python

import pulumi
import pulumi_kubernetes as k8s

app = k8s.apps.v1.Deployment('myapp',
    spec=k8s.apps.v1.DeploymentSpecArgs(
        replicas=3,
        selector=k8s.meta.v1.LabelSelectorArgs(
            match_labels={'app': 'myapp'},
        ),
        template=k8s.core.v1.PodTemplateSpecArgs(
            metadata=k8s.meta.v1.ObjectMetaArgs(
                labels={'app': 'myapp'},
            ),
            spec=k8s.core.v1.PodSpecArgs(
                containers=[k8s.core.v1.ContainerArgs(
                    name='myapp',
                    image='nginx:latest',
                    ports=[k8s.core.v1.ContainerPortArgs(container_port=80)],
                )],
            ),
        ),
    ),
)

Testing Infrastructure

import { describe, it, expect } from 'vitest';
import * as pulumi from '@pulumi/pulumi';

pulumi.runtime.setMocks({ ... });

describe('Infrastructure', () => {
  it('should create S3 bucket with website config', async () => {
    const { bucket } = await import('./index');
    const website = await bucket.website.promise();
    expect(website?.indexDocument).toBe('index.html');
  });
});

Key Features

Real languages — TypeScript, Python, Go, C#, Java
IDE support — autocomplete, type checking, refactoring
Testing — unit test infrastructure like application code
State management — Pulumi Cloud or self-managed backends
All providers — AWS, Azure, GCP, K8s, 150+ providers
