My day job is as a Kubernetes project contributor, and Postgres Foreign Data Wrappers have always held a special place in my heart. Combining them is only natural.

Kubernetes uses etcd as its data store, but it maps very well onto Postgres. All APIs follow a very uniform schema that makes programmatically mapping objects to tables easy. The user experience I settled on makes it easy to present exactly the data you want, not the entire object.

Unlike most postgres extensions, the Kubernetes wrapper is written in go. Kubernetes is a Go project, and as a Kubernetes contributor my Go is a lot better than my C. Luckily, Go has a robust FFI for C that makes working in both languages easier than it might be otherwise. I will give a primer on how this works, and

I’ll show off the sort of queries you can do with a Postgres Kubernetes database, especially ones that would be difficult from the command line. Finally, ideas for future expansion will be discussed to make the wrapper even more useful.
