Cloud Native Application Development is a one way of speeding up building web applications, using micro-services, containers and orchestration tools.
As the first step, this repository shows How to build a Dockerized RESTful API application using Go.
- Usage of Docker and Docker Compose.
- Usage of Golang and MySQL Alpine images.
- Usage of Docker Multistage builds.
- Health API for K8s liveness & readiness.
- Usage of Goose for Migrations.
- Usage of GORM as the ORM.
- Usage of Chi as the Router.
- Usage of Zerolog as the Logger.
- Usage of Validator.v10 as the Form Validator.
- DB: 230MB
- App
- Development environment: 667MB
- Production environment: 21MB
💡 Building Docker image for production
docker build -f prod.Dockerfile . -t myapp_app
- Store executable packages inside the
cmdfolder. - Store database migrations inside the
migrationsfolder. - Store main application code inside the
appfolder. - Store reusable packages like configs, utils in separate folders. This will be helpful if you are adding more executable applications to support web front-ends, publish/subscribe systems, document stores and etc.
