Simple Pulumi Automation API Script (Python) - Pulumi-automation Typing CST Test
Simple Pulumi Automation API Script (Python) — Pulumi-automation Code
A simple Pulumi Automation API script in Python to create an S3 bucket.
# pulumi/demo/automation_api.py
import pulumi
from pulumi_automation import LocalWorkspace
stack = LocalWorkspace.create_stack(stack_name='dev', project_name='demo_project')
bucket = pulumi.aws.s3.Bucket('my-bucket')
stack.up()Pulumi-automation Language Guide
Pulumi Automation API enables programmatic Infrastructure as Code (IaC) by allowing developers to define, deploy, and manage cloud infrastructure directly from code in languages like TypeScript, Python, Go, and C#. It provides full automation capabilities for CI/CD and custom tooling.
Primary Use Cases
- ▸Programmatic provisioning of cloud infrastructure
- ▸Automating CI/CD pipelines for infrastructure changes
- ▸Embedding infrastructure logic into custom applications
- ▸Testing and validating infrastructure programmatically
- ▸Multi-cloud infrastructure orchestration from code
Notable Features
- ▸Use familiar programming languages (TypeScript, Python, Go, C#) for IaC
- ▸Full automation API for programmatic infrastructure management
- ▸Supports multiple cloud providers and Kubernetes
- ▸Preview, update, and destroy infrastructure via code
- ▸Integration with CI/CD pipelines and testing frameworks
Origin & Creator
Created by Pulumi, Inc. to extend Pulumi’s cloud infrastructure platform for programmable automation of deployments within custom applications and CI/CD pipelines.
Industrial Note
Pulumi Automation is often used by platform teams and DevOps engineers who need to integrate IaC tightly with CI/CD pipelines, testing frameworks, and custom automation tools, allowing infrastructure to be treated as a software library.
Quick Explain
- ▸Pulumi Automation API allows embedding Pulumi programs into applications or pipelines.
- ▸Infrastructure is defined imperatively using familiar programming languages rather than YAML or JSON.
- ▸Supports multiple cloud providers such as AWS, GCP, Azure, Kubernetes, and more.
- ▸Enables full lifecycle automation: preview, update, refresh, and destroy resources.
- ▸Ideal for programmatically managing infrastructure in CI/CD, GitOps, or custom dev workflows.
Core Features
- ▸Pulumi stacks can be managed programmatically
- ▸Supports stack outputs, configuration, secrets, and state management
- ▸Automation API allows embedding Pulumi programs into apps or scripts
- ▸Programmatic control over lifecycle: preview, up, destroy, refresh
- ▸Works with local, cloud, or backend state management
Learning Path
- ▸Learn Pulumi basics and CLI usage
- ▸Understand resource concepts and stacks
- ▸Practice Automation API with sample scripts
- ▸Integrate Automation API into CI/CD pipelines
- ▸Experiment with multi-cloud deployments
Practical Examples
- ▸Provision AWS S3 bucket using TypeScript Automation API
- ▸Programmatically deploy Kubernetes cluster with Python
- ▸CI/CD pipeline that dynamically creates environments per branch
- ▸Automated testing of infrastructure updates in a staging environment
- ▸Multi-cloud deployments orchestrated via Go Automation API scripts
Comparisons
- ▸Pulumi vs Terraform - code-first imperative vs declarative IaC
- ▸Pulumi vs Crossplane - programmatic API vs Kubernetes-native CRDs
- ▸Pulumi vs Ansible - full automation vs configuration management
- ▸Pulumi vs CloudFormation - multi-cloud code vs provider-specific templates
- ▸Pulumi vs CDK - similar programmatic IaC, Automation API enables custom embedding
Strengths
- ▸Full flexibility of a programming language for infrastructure
- ▸Tight integration with CI/CD pipelines
- ▸Supports multi-cloud deployments
- ▸Automates infrastructure operations without manual CLI steps
- ▸Enables testing and validation of infrastructure code
Limitations
- ▸Requires programming knowledge in supported languages
- ▸Less declarative than YAML/JSON-based IaC tools
- ▸Automation API adds complexity for simple use cases
- ▸State management setup needed (local or Pulumi Service)
- ▸Limited pre-built abstractions compared to declarative frameworks
When NOT to Use
- ▸For teams preferring fully declarative YAML or JSON
- ▸When no programming expertise is available
- ▸For simple single-cloud deployments without automation needs
- ▸If CLI-only manual deployment is sufficient
- ▸Where Kubernetes-native CRDs are preferred (use Crossplane instead)
Cheat Sheet
- ▸AutomationAPI.createStack - create or select stack programmatically
- ▸stack.preview() - preview infrastructure changes
- ▸stack.up() - apply updates
- ▸stack.destroy() - remove resources
- ▸stack.outputs() - read outputs programmatically
