Postgres and Docker for Go Developers

Setting up a reliable local database environment is a critical first step for modern application development. By combining the power of Postgres with Docker, you can spin up isolated, reproducible database instances instantly without polluting your local operating system. This text-based course guides you through configuring a Postgres database container and seamlessly connecting it to a Go application. You will transition from understanding basic containerization concepts to writing robust Go code that interacts with your database using modern connection pooling and environment variables. What you'll learn: Understand the fundamental concepts of containerization and relational databases; Configure and run a Postgres database locally using Docker and Docker Compose; Manage database schema migrations and persistent data storage with Docker volumes; Establish secure connections between a Go application and Postgres using modern drivers; Implement environment variables and configuration patterns for secure database credentials; Apply basic database connection pooling and structured logging in Go. You will start with core definitions and step-by-step written guides on writing a docker-compose.yml file. From there, you will read through practical Go code examples to establish, test, and manage your database connection. This course is designed for beginner Go developers and backend enthusiasts who want to learn database containerization. No prior Docker experience is required, though basic familiarity with Go syntax is helpful. Start reading today to build a clean, containerized data layer for your next Go project.
