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 Using Remote Hosts

In the previous chapter, we created CI/CD tasks by using Docker Compose. We also created various environments that we can use and utilize regarding the scenario presented.

In this chapter, we will focus on deploying our Docker applications to a remote host. While developing an application, there are various reasons why you may not want to deploy your application to another host: the application can be resource-intensive, you may want to share the progress with a colleague or the host, the application is getting deployed to, may have access to resources through the network that your workstation doesn’t. A remote host could be a solution to those issues since it allows us to deploy a Docker application to another workstation and thus make it available externally.

In this chapter, we will cover the following topics:

  • Docker remote hosts
  • Creating a remote Docker host
  • Docker Contexts
  • Deploying Compose to remote...
