Kubernetes is an open source system for automating deployment, operations, and scaling of containerized applications. It’s one of the promising options you have for deploying your container-based applications to the Internet. In this session we’ll take a look at the concepts of Kubernetes and then go trough all steps necessary to launch and maintain a real-world PHP application in your own Kubernetes cluster.

5. How do you deploy
PHP applications?

7. Containers are not light-weight
virtual machines.
They are mostly a clever way to
isolate processes.

9. Managing
containers ain’t
easy.

want to build an external version of
the Borg task scheduler. One of our
most important competitive
advantages. The one we don’t even
talk about externally. And, on top of
that, you want to open source it?"
