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.

Pushing to an Azure container registry

An Azure container registry will play a significant role in our deployment. It will be a universally available registry well integrated with the Azure infrastructure that we will provision.

A basic step to creating resources on Azure is to manage them under a resource group. Think of an Azure resource group as a container that includes all the resources needed for our application. It is a way to logically separate infrastructure. For example, deleting a resource group will lead to the deletion of the resources provisioned under this resource group.

Our Azure container registry as well as our ACI will reside in a resource group that we will provision. This can be done in many ways – for example, through the command line, the Azure portal, as well as using Terraform.

Adding a resource group via Terraform should look like this:

resource "azurerm_resource_group" "guide_to_docker_compose_resource_group" {
