Docker makes orchestration and deployment much more simple. In this recipe, we'll set up a connection to MongoDB, inserting a document and querying it all from Docker containers. This recipe will set up the same environment as the Using NoSQL with MongoDB and mgo recipe, in Chapter 5, All about Databases and Storage, but will run the application and environment inside of containers and will use Docker compose to orchestrate and connect them. This can later be used in conjunction with Docker Swarm, an integrated Docker tool that allows you to manage a cluster, to create and deploy nodes that can be scaled up or down easily, and to manage load balancing (https://docs.docker.com/engine/swarm/). Another good example of container orchestration is Kubernetes (https://kubernetes.io/), a container orchestration framework written by Google using...

Overview of this book
Go (a.k.a. Golang) is a statically-typed programming language first developed at Google. It is derived from C with additional features such as garbage collection, type safety, dynamic-typing capabilities, additional built-in types, and a large standard library.
This book takes off where basic tutorials on the language leave off. You can immediately put into practice some of the more advanced concepts and libraries offered by the language while avoiding some of the common mistakes for new Go developers.
The book covers basic type and error handling. It explores applications that interact with users, such as websites, command-line tools, or via the file system. It demonstrates how to handle advanced topics such as parallelism, distributed systems, and performance tuning. Lastly, it finishes with reactive and serverless programming in Go.
