A Developer's Essential Guide to Docker Compose

By: Emmanouil Gkatziouras

Overview of this book

Software development is becoming increasingly complex due to the various software components used. Applications need to be packaged with software components to facilitate their operations, making it complicated to run them. With Docker Compose, a single command can set up your application and the needed dependencies. This book starts with an overview of Docker Compose and its usage and then shows how to create an application. You will also get to grips with the fundamentals of Docker volumes and network, along with Compose commands, their purpose, and use cases. Next, you will set up databases for daily usage using Compose and, leveraging Docker networking, you will establish communication between microservices. You will also run entire stacks locally on Compose, simulate production environments, and enhance CI/CD jobs using Docker Compose. Later chapters will show you how to benefit from Docker Compose for production deployments, provision infrastructure on public clouds such as AWS and Azure, and wrap up with Compose deployments on said infrastructure. By the end of this book, you will have learned how to effectively utilize Docker Compose for day-to-day development.

Deploying Docker Compose to AWS

In the previous chapter, we deployed our application to a Docker host. The feature of deploying to a remote host could help in many ways, for example, we could share the application with another individual or use the remote host for development and testing purposes. Deploying to a remote host brings us closer to the context of deploying to production. However, a deployment to a remote host is not up to the standards of a production deployment. A production deployment needs our application to be highly available, secure, and accessible through a load balancer, and the logs of the application need to be easy accessible and securely stored.

This chapter is all about bringing our Docker Compose application to production. Elastic Container Service (ECS) is one of the container orchestration services that AWS provides. ECS is integrated with Docker Compose, therefore by using an existing Compose application we can have a cloud-native application deployed...
