I wrote an advanced book about Kubernetes (covers Kubernetes 1.6). In addition to the basics of pods, services and deployments I dive deeply into advanced topics like storage, networking, load balancing, cloud federation, monitoring, plugins, API and packaging. You can read it for free (with a free trial) on SafariOnline:

If you like the book you can buy it from PacktPub: https://www1.packtpub.com/virtualization-and-cloud/mastering...
It's available on Amazon too: https://www.amazon.com/Mastering-Kubernetes-Gigi-Sayfan/dp/1...
I would love to hear what you think and answer any questions!
