You would probably find there are performance penalties in areas Docker don't really bother benchmarking or even talking about since they don't align to the design goals. I've only seen some fairly rudimentary demonstrations of VNC and X over the Network for isolating GUI apps in Docker.
- shykes 13y agoDocker author here. I really doubt performance would be a problem. Namespaced linux processes access devices the same way every other process does: by getting a file descriptor to it and making syscalls against that. What we need to figure out is a portable way for a docker container to declare "I need access to the following devices". I would love to work with anyone interested to add that to the docker APIs for 1.0. I think long-term stable binary delivery is an important thing to do and I would like to help. Ping me at solomon@docker.com about this anytime.
