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 Azure

In the previous chapter, we deployed our application to AWS. We deployed the application using autoscaling and health checks, and we even managed to access the application through a DNS domain. In this chapter, we shall focus on another popular cloud provider, Azure. Azure provides us with Azure Container Instances (ACI), a seamless way to run Compose-based applications without managing any infrastructure. Deploying to ACI is simple; first, we shall push the application images to an Azure container registry, and then, with a few adjustments, we shall deploy our application to Azure ACI.

Deploying to ACI comes with less infrastructure maintenance overhead as well as with the simplicity of the Compose syntax.

We will cover the following topics in this chapter:

  • An introduction to ACI
  • Pushing to an Azure container registry
  • Adapting Compose files for Azure container groups
  • Deploying your Compose application to Azure container...
