Summary

Hopefully, at this point, we have become familiar with interacting with Docker Engine. We have prepared a Docker host where we will run our containers. We built a PKI to ensure secure communication between our Docker host and our Docker client workstation, and we built a small Docker Swarm cluster consisting of multiple Docker hosts.

We accomplished all of this by logging in to servers and manually typing configuration commands. In the next chapter, we'll learn to automate provisioning these Docker hosts—and save us from typing!
