Summary

In this chapter, we created a multi-container application running on Docker Compose and used Compose features such as building and tagging an image, communicating between containers using the same network, health checks, labeling, and ENTRYPOINT configuration. Those features make it easier to transition from manual Docker-based management to a Compose-based one. By being able to package a complex application, we lay the foundation for deploying and distributing our multi-container application using Compose.

The next chapter is about networking and volume management, including understanding how the concept of Docker volumes and networks is mapped to Compose.
