In related news: Prometheus is awesome but not limited to K8S (!) Also, there are other interesting container monitoring solutions such as sysdig , Ruxit and Datadog .

Data gravity is indeed a problem (that's why stateless apps and services are easier to containerize) but luckily there are a couple of options: from leveraging distributed filesystems such as GlusterFS to Flocker and REX-Ray to—esp. popular in the cloud—NFS or CIFS mounts.

Yup, totally agreed re service discovery—unfortunately the polls are limited to 4 options ;) However, I'm very much aware of the challenges in this area and that's also partially the reason I wrote the free O'Reilly book on Docker Networking and Service Discovery .

Show your manager RFC6068 —it's an Internet standard and not something you or your project manager decide (FWIW, neither do I ;).
