readme, troubleshooting, or play should ensure metal_lb_ip_range and apiserver_endpoint have valid ips in flannel_iface

RE: closed issue

Expected Behavior

Document and or assert metal_lb_ip_range and apiserver_endpoint have valid ips in flannel_iface

Current Behavior

If the master and or node hosts flannel_iface eg eth0 has a netmask of 255.255.255.0 and an ip of 192.168.0.*
vars of

• apiserver_endpoint: "192.168.30.222"
• metal_lb_ip_range: "192.168.30.80-192.168.30.90"

are invalid

Steps to Reproduce

given

docs, but use invalid ips like above

when

ansible-playbook site.yml

then

docs and or trouble shooting or assert should explain the problem

Possible Solution

• the site.yml or one of its roles could assert
  • that the ips are in the correct range for masters and nodes
• the doc could mention this
• troubleshooting could mention this

Thanks

Tim, if you find this reasonable I'd be happy to give a PR or PRs a go..
possible PRs:

• doc
• troubleshooting
• assert in a role or play

This would be awesome! If you are going to do that work, another thing to assert is that the apiserver_endpoint does not fall into the range of the metal_lb_ip_range . That seems to be another common pitfall.
