In this article, I explore how Docker Compose can simplify software development, using Ruby on Rails as an example project. Docker Compose simplifies the setup and teardown of a project, reduces inconsistencies in development environments, and makes it easier to add ancillary services such as database and caching servers. I demonstrate this by creating a new Rails project, setting up a docker-compose.yml file, and adding services like PostgreSQL and Redis. Once done, I run and develop the new application in Docker. This process eliminates the need to juggle multiple versions of tools and services on a workstation, minimizes bugs caused by different development environments, and conserves resources. I also share insights on how to clone the example repo, create a new project, add the first service to Docker Compose, and develop the application in Docker.
