Multiple haproxy instances under kubernetes

[tuxillo]

Currently we're evaluating haproxy as a LB under kubernetes. Our setup is using the haproxy helm chart (https://github.com/haproxytech/helm-charts/tree/main/haproxy) deployed as daemonset, so there will be as many instances as there are nodes.

Since one of our use cases is going to require changing frontends/backends dynamically, we noticed it could be done with the Data Plane API. But we haven't found a way of propagating those changes to all the haproxy instances. As far as we know, a data plane API process has to run on each instance, because it does its magik via the stasts socket, and has to be called individually over each haproxy.cfg file to be able to persist the changes.

Any pointers?

I guess my question is a bit more platform specific.
