Description

Introduction

As cloud infrastructures grow in complexity, maintaining reliability, security, and consistency becomes critical. Pulumi allows developers to define infrastructure as code using programming languages such as TypeScript, enabling automated deployments and scalable architectures. However, to ensure these deployments are robust, teams must implement testing, manage secrets securely, and handle configurations effectively.

This course, Infrastructure Testing, Secrets, and Configuration Management in Pulumi, focuses on best practices and practical strategies for testing infrastructure code, managing sensitive data, and configuring multi-environment deployments. You will learn how to validate infrastructure changes, protect secrets, and streamline configuration management across Pulumi projects.

By the end of this course, learners will be able to ensure their Pulumi-managed infrastructure is secure, tested, and consistent across all environments.

Prerequisites

Before starting this course, learners should have:

• Basic understanding of cloud computing and Infrastructure as Code (IaC)

• Working knowledge of JavaScript or TypeScript

• Familiarity with Pulumi basics (resources, stacks, and deployments)

• Knowledge of Git and version control concepts

Tools required:

• Node.js and npm installed

• Pulumi CLI installed

• Cloud account (AWS, Azure, or GCP) for deployments

• Visual Studio Code or preferred editor
