This is a WIP document.
Now that we have a more stable release chain of actix-web (version 4 is out), it is easier to write guides, and will use this heavily battle tested web-framework.
Heavy Weight Framework
actix-web crate is fairly heavy-weight for just exposing metrics. For a simpler web framework that we have partial support for, consider axum and our version-rs application using it.
This document is unfinished so we refer to controller-rs which is a full-featured example of using actix-web with kube.
