 1 | # arve0/timemachine
 2 | Netatalk running in docker for time machine backups.
 3 | 
 4 | ```
 5 | docker pull arve0/timemachine
 6 | docker run -e "PASSWORD=asdf" -v /host/mnt/backup:/backup -p 548:548 --net=host -d arve0/timemachine
 7 | ```
 8 | 
 9 | Connect with timemachine:asdf. If environment variable `PASSWORD` is not set, *timemachine* is the default password.

11 | # notes on bonjour/avahi/zeroconf
12 | [Network discovery](http://en.wikipedia.org/wiki/Bonjour_(software)) only works if afp daemon is on same network as client. Therefore `--net=host` is required if you would like the disk to show in Finder. If you don't need this, you can remove `--net=host` and connect in Finder with `cmd+k` -> `afp://hostname/`
13 | 
14 | Note that `--net=host` doesn't work with ubuntu trusty 14.04: https://github.com/docker/docker/issues/5899
