Building Microservices with Go

By: Nic Jackson

Overview of this book

Microservice architecture is sweeping the world as the de facto pattern to build web-based applications. Golang is a language particularly well suited to building them. Its strong community, encouragement of idiomatic style, and statically-linked binary artifacts make integrating it with other technologies and managing microservices at scale consistent and intuitive. This book will teach you the common patterns and practices, showing you how to apply these using the Go programming language. It will teach you the fundamental concepts of architectural design and RESTful communication, and show you patterns that provide manageable code that is supportable in development and at scale in production. We will provide you with examples on how to put these concepts and patterns into practice with Go. Whether you are planning a new application or working in an existing monolith, this book will explain and illustrate with practical examples how teams of all sizes can start solving problems with microservices. It will help you understand Docker and Docker-Compose and how it can be used to isolate microservice dependencies and build environments. We finish off by showing you various techniques to monitor, test, and secure your microservices. By the end, you will know the benefits of system resilience of a microservice and the advantages of Go stack.

Docker Compose


That was all super easy-ish, let's now take a look at a compelling feature of Docker that allows you to start multiple containers at once with your stack definition stored in a handy YAML file.

Installing Docker Compose on Linux

If you have either Docker for Mac or Docker for Windows installed then it already comes bundled with docker-compose, if however, you are using Linux, then you may need to install this yourself as it does not come as part of the default Docker package.

To install Docker Compose on Linux, execute the following command in your terminal:

$ curl -L https://github.com/docker/compose/releases/download/1.8.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose  && chmod +x /usr/local/bin/docker-compose

Before we look at how we can run our application with docker-compose, let's take a look at the file we are going to run and some of the important facets of it:

1 version: '2'                                                              ...
