flannel_iface (or any other _iface) should have a variable set for each node

[alfredodeluca]

Expected Behavior

As I have different NIC card I should be able to set the flannel_iface or cilium or calico iface for each node

Current Behavior

If I set eth0 on one node but on different nodes I don't have eth0 set, the installation fails

Steps to Reproduce

1. Set flannel_iface to eth0
2. Run the deploy
3. if you have a different NIC on nodes the deployment will fail

Possible Solution

• [ x] I've checked the General Troubleshooting Guide

[berendt]

You have to use the host vars to set a flannel_iface parameter per host (or to overwrite the value set in all.yml for a single host with a different interface name).
