# Important: the name for the heat resource kube-minion below must |
|
# not contain "_" (underscore) because it will be used in the |
|
# hostname. Because DNS domain name does not allow "_", the "_" |
|
# will be converted to a "-" and this will make the hostname different |
|
# from the Nova instance name. This in turn will break the load |
|
# balancer feature in Kubernetes. |
