Open Stack

Flavio,

Atleast for the kubernetes variant of kolla, bindmounting will always be used as this is fundamentally how configmaps operate.  In order to maintain maximum flexilbility and compatibility with kubernetes, I am not keen to try a non-configmap way of doing things.

    mmh, one thing I liked about this effort was possibility of stop bind-mounting
    config files into the containers. I'd rather find a way to not need any
    bindmount and have the services get their configs themselves.
