First KubeCon in a while I haven’t done anything for (didn’t even buy an ticket). This post is largely for myself, but thought I’d put some thoughts here public. All talks referenced were recently published on the CNCF youtube channel, and the posts here are really just my notes (make of them what you will).[Read More]
Evolution of kube
Tower, Hyper, Websockets.
After a quarter year of extensive improvements to kube, it’s time to take a birds-eye view of what we got, and showcase some of the recent improvements. After all, it’s been about 40 kube releases, one major version of tokio, one extremely prolific new contributor, and one kubecon talk since my (very outdated) last blog post.[Read More]
A generic kubernetes client
Shaving a yak for a client-rust
It’s been about a month since we released
kube, a new rust client library for kubernetes. We covered the initial release, but it was full of naive optimism and uncertainty. Would the generic setup work with native objects? How far would it extend? Non-standard objects? Patch handling? Event handling? Surely, it’d be a fools errand to write an entire client library?
With the last
0.10.0 release, it’s now clear that the generic setup extends quite far. Unfortunately, this yak is hairy, even by yak standards.
Kubernetes operators in rust
Writing light weight cloud services without go
When interacting with kubernetes it’s generally been standard practice to use either client-go via go, or
kubectl via shell.
While these are good, non-controversial choices, the advancement of client libraries, and smarter openapi bindings, combined with the generics and procedural macros of rust-lang, it’s now quite possible to write fully fledged kube operators, using slim rust kube clients.[Read More]
Building a secure yaml api for kubernetes
At babylon health we have a ton of microservices running on kubernetes that are, in turn, controlled by hundreds of thousands of lines of autogenerated
