Discovering and load balancing containers

In the previous recipe, we looked at the benefits of a user-defined bridge network and the steps to create and examine a user-defined bridge network. In this recipe, we will build a container topology, as depicted in the following diagram:

• Service discovery through an embedded DNS server
• DNS-based load balancing
