In this chapter, we went all the way to create our own PaaS by adding deployment to the process. What we looked into up to this chapter was all about organizing containers and direct incoming traffic so that visitors can reach the correct container.
With Dokku, we don't have to worry about that; all we have to care about is our code. As soon as we push our code, Dokku takes over and does the right things. Dokku makes it look really easy and that is why, I started from manually creating and linking containers and configuring reverse proxies—so that you would understand what Dokku does.
The next chapter takes us to the bleeding edge: what's being developed right now that can take private PaaS with Docker one step further?
