Re: Novatools ...
Perhaps I'm missing something, but I'm not sure what you mean by
"one API". Each project/service will be driving their own API,
no? For example do you expect one CLI tool for swift, nova, and a
I see John's points with allowing each service to drive their own
API/tools (hopefully following some cross-project guidelines so they
are consistent), and then possibly supplying a "super tool" that allows
complex orchestration using the other tools when needed. For example:
os-super-tool create cluster <network> <nodes> <images> ...
This would in turn use os-compute, os-network, etc.
We could also do some tool reflection to allow:
To be the same as:
os-super-tool compute <args>
So you can only use os-super-tool if you don't want to remember all
