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.

Using Docker Compose with Bitbucket pipelines

Bitbucket pipelines are a CI/CD solution for the repositories hosted on Bitbucket. By having a repository hosted on Bitbucket instead of using an external solution for CI/CD purposes, Bitbucket pipelines can be very useful since they are readily available and seamlessly integrated. As with the previous case in GitHub Actions, we will follow the same process.

Creating your first Bitbucket pipeline

In order to enable Bitbucket pipelines, you need to create a bitbucket-pipelines.yml file in the root directory of your project. Then, you can enable the pipelines in your repository through the settings:

Figure 9.1 – Bitbucket pipelines enabled

Once the pipelines are enabled, Bitbucket will proceed with executing the instructions specified in the bitbucket-pipelines.yml file.

The bitbucket-pipelines.yml base will be the following:

image: atlassian/default-image:3
options:
  docker: true
