Docker Unison

This image runs plain unison as entrypoint. It is adviced to create external docker volume containers for:

• /path/to/data - the destination of the sync
• /root/.ssh - the ssh key
• /root/.unison - the unison working data

If you create a default.prf in the working directory of unison, the docker container would not need any further options and running those default settings.

Setup

create a data volume container for the data to synchronize

sudo docker create -v /path/to/data --name synceddata ubuntu

create a data volume container for the ssh key and register the key on the remote server

sudo docker run -it --name sshdata thomass/ssh-client ssh-keygen -t rsa -C "key for docker unison"
sudo docker run -it --rm --volumes-from sshdata thomass/ssh-client ssh-copy-id [-p <remote-port>] [<user>@]<remote-ip>

create a data volume container for all unison data

sudo docker create --name unisondata --volumes-from synceddata --volumes-from sshdata -v /root/.unison ubuntu

setup the default sync profile

sudo docker run -it --rm --volumes-from unisondata ubuntu vim.tiny /root/.unison/default.prf

Insert following (example) settings

root = /path/to/data
root = ssh://[<user>@]<remote-ip>[:<remote-port>]//path/to/data

Usage

Now you can run a synchronization any time as following

sudo docker run -it --rm --volumes-from unisondata thomass/unison
