I’ve been trying and debug this thing for more than a week now, i have a Rancher 2.6 environment (but it happened even in Rancher 2.5.9) and i want to provision a Cluster using vSphere.
Following the docs everything goes well and the cluster deploys properly.
Issue is, after a hour of two from the deployment, the cluster starts misbehaving and after a while plain fails, because the DHCP lease has gone and one of the master nodes has changed his IP.
DHCP is provided by a PFSense on a “private DMZ network” configured as a VLAN on vSphere, configuration on cloudinit is completely clean and i’m running stock Ubuntu Server 20.04 cloudinit images.
Am i doing something wrong?
