Need Help Installing Neutron with OpenStack Helm

Asked by TechWiz42
I'm setting up OpenStack using the OpenStack Helm project, but I've run into an issue specifically with the Neutron setup. I am using Cilium as my Container Network Interface (CNI), and whenever I install Neutron, my IP routes from Cilium get overwritten. I'm currently using 'routingMode: native' and have 'autoDirectNodeRoutes' set to true. I've dedicated network interfaces for this: Eth0 for Cilium and Eth1 for Neutron. Can anyone provide guidance on how to correctly install Neutron under these conditions?

Hey there! I'm one of the maintainers for OpenStack Helm. For your issue with Neutron, I suggest posting in our Slack channel on the Kubernetes Slack. It would be super helpful to gather more diagnostic info before and after your installation. The community is pretty responsive, and they'll help you troubleshoot effectively. Good luck!

Sounds like you're taking on a pretty advanced setup, combining OpenStack with Kubernetes! For the Neutron issue, I recommend double-checking your network configuration in the YAML file you're using. Sometimes routing conflicts can arise if the network interfaces aren't configured properly in OpenStack. If your Cilium routes are being overwritten, it's likely due to how the bridge is set up. Have you tried reaching out to the OpenStack Helm Slack channel for more detailed support? They might be able to give you specific insights based on your setup.
