Ive played with ROS2 on k8s/openshift including discoveryserver
The SPDP makes assumptions about the eth endpoint. I got around this as well using downward api and got stuff working using a server; However the resilience is a point of concern. the underlying implementation assumes that IPs don’t change, this assumption is invalid for container orchestration environments where the same pod (think of this as a compute node) may come back to life (reboot) with a different IP address.
Additionally the discoveryserver also now bhaves as a ROS1 master and needs its own resilience.
Another major show-stopper is the lack of support for DNS based FQDN. K8s does provide stable netwrok identity IP and dns using a service abstarction . This however is via DNSMASQ - the pod internal IP is != the stable IP , this causes issues too
