Summary

In this chapter, we learned about container virtualization. Containers are similar to virtual machines in their ability to isolate computing resources but different in the sense that they are lightweight and fast to deploy.

We saw how to use Docker containers to build Python applications and docker-compose to build multi-container applications on a single host.

Later in the chapter, we learned how networks are constructed with Docker containers by using the default bridge, custom bridges, and host options. Containers can also help with network operating system testing using the Containerlab project.

In the next chapter, we will look at how we can use Python in network security.
