Hi Gus,

I am not sure to understand the use case. Can you elaborate ?

Do you want to run containers on your diskless host ?
or
Do you want to have your diskless host to run inside a container ?

I did recently a configuration with a tftp server running inside a 
container and a pxe host to boot inside it.
It was working like a charm. Maybe it is what you are looking for ?
