Overview of this book

Awarded as one of the best books of all time by BookAuthority, Cloud Native Programming with Golang will take you on a journey into the world of microservices and cloud computing with the help of Go. Cloud computing and microservices are two very important concepts in modern software architecture. They represent key skills that ambitious software engineers need to acquire in order to design and build software applications capable of performing and scaling. Go is a modern cross-platform programming language that is very powerful yet simple; it is an excellent choice for microservices and cloud applications. Go is gaining more and more popularity, and becoming a very attractive skill. This book starts by covering the software architectural patterns of cloud applications, as well as practical concepts regarding how to scale, distribute, and deploy those applications. You will also learn how to build a JavaScript-based front-end for your application, using TypeScript and React. From there, we dive into commercial cloud offerings by covering AWS. Finally, we conclude our book by providing some overviews of other concepts and technologies that you can explore, to move from where the book leaves off.

Deploying to Kubernetes


Using GitHub and Travis, we have now automated the entire workflow from changing the application's source code over building new binaries to creating new Docker images and pushing them to a container registry. That is great, but we are still missing one crucial step, that is, getting the new container images to run in your production environment.

In the previous chapters, you have already worked with Kubernetes and deployed your containerized applications into a Minikube environment. For this section, we will assume that you already have a publicly accessible Kubernetes environment up and running (for example, using a kops-provisioned cluster in AWS or the Azure Container Service).

First of all, Travis CI will need to access your Kubernetes cluster. For this, you can create a service account in your Kubernetes cluster. This Service Account will then receive an API token that you can configure as a secret environment variable in your Travis build. To create a service...
