Add option to configure devices in yaml file

[twendt]

Example:
tvheadend:
image: tvheadend
devices:

• "/dev/dvb/adapter0/dvr0:/dev/dvb/adapter0/dvr0"

Format for each entry is HOST:CONTAINER.
If only HOST is given then the file will be the same
inside the container.

Note, this is actually a vendored version of http://github.com/docker/docker-py

These changes should be made upstream

[twendt]

Thank you for the info. I didn't notice that. Is there a certain reason why there is a copy of it in here?
I would try to bring it upstream, but I don't really know how to get started with it. I will see what I can do.

Check out the discussion in #375

You might be able to just generate a patch with git diff and try to git apply it.

I requested the changes upstream now. How do we get the new version of docker-py in here then once the change hopefully got merged?

Hi @twendt – new version of docker-py should be in Compose now! Would love to get this in.

As #1400 has been merged, I guess this PR could/should be closed ;).
