Yeah sure, so here's my setup:
- 3 cluster nodes (192.168.1.11-13)
- a virtual IP (192.168.1.10) that's assigned to the cluster and managed
with kube-vip
- cluster-internal traffic is sent via flannel in vxlan mode (k3s
default setting)
- IPTables changes outbound traffic's source IP to the node IP via NAT
(k3s default setting)
- I'm using the official LMS 8.1.1 container with HTTP_PORT set to 9001
- Traefik 2 operates as Loadbalancer and Ingress Router. It's set up to
bind to LMS' ports (TCP 9001, TCP+UDP 3484, TCP 9090) on any ip address
(0.0.0.0) the node has.
- I'm using Traefik's IngressTCP and IngressUDP to route traffic to
LMS.
