Building a Dockerized RESTful API application in Go

👨‍🏫 In this series…

In this series, we are going to build a Dockerized Go RESTful API for a bookshelf with these steps:

• Create a basic server using Go’s net/http package and Dockerize it.
• Add the database, SQL migration files, and create the migrate app to run these migration files.
• Implement dynamic application configurations via environment variables.
• Integrate Chi, add initial API routes, and generate OpenAPI specifications.
• Integrate GORM, implement repository functions with tests, and invoke repository from the handlers.
• Enhance error handling and integrate Validator v10 for form validations.
• Implement error logs and request logs via Zerolog.

📦 The codebase

The completed API application supports the following API endpoints.

Name	HTTP Method	Route
Health	GET	/livez
List Books	GET	/v1/books
Create Book	POST	/v1/books
Read Book	GET	/v1/books/{id}
Update Book	PUT	/v1/books/{id}
Delete Book	DELETE	/v1/books/{id}

The sourcecode of the completed project can be found in learning-cloud-native-go/myapp GitHub repository.

OK, Let’s get it started!
