Docker Deep Dive

9: Deploying Apps with Docker Compose

In this chapter, we’ll look at how to deploy multi-container applications using Docker Compose.

Docker Compose and Docker Stacks are very similar. In this chapter we’ll focus on Docker Compose, which deploys and manages multi-container applications on Docker nodes running in single-engine mode.

Deploying apps with Compose - The TLDR

Modern cloud-native apps are made of multiple smaller services that interact to form a useful app. We call this pattern “microservices”. A simple example ...
