Docker-Unison

A docker volume container using Unison for fast two-way folder sync. Created as an alternative to slow boot2docker volumes on OS X.

The docker image is available on Docker Hub:
registry.hub.docker.com/u/leighmcculloch/unison/

Usage

Docker

First, you can launch a volume container exposing a volume with Unison.

$ CID=$(docker run -d -p 5000:5000 -e UNISON_VERSION=2.48.3 -e UNISON_WORKING_DIR=/unison leighmcculloch/unison)

You can then sync a local folder to /unison in the container with:

$ unison . socket://<docker>:5000/ -auto -batch

Next, you can launch a container connected with the volume under /unison.

$ docker run -it --volumes-from $CID ubuntu /bin/sh

Docker Compose

If you are using Docker Compose to manage a dev environment, use the volumes_from directive.

The following docker-compose.yml would mount the /unison folder from the unison container inside your mywebserver container.

mywebserver:  
  build: .  
  volumes_from:  
    - unison  
unison:  
  image: leighmcculloch/unison  
  environment:  
    - UNISON_VERSION=2.48.3  
    - UNISON_WORKING_DIR=/unison  
  ports:  
    - "5000:5000"

You can then sync a local folder, using the unison client, to /unison in the container with:

$ unison . socket://<docker>:5000/ -ignore 'Path .git' -auto -batch

You could combine it with fswatch to sync automatically when files change:

$ fswatch -o . | xargs -n1 -I{} unison . socket://<docker>:5000/ -ignore 'Path .git' -auto -batch

Installing Unison Locally

Unison requires the version of the client (running on the host) and server (running in the container) to match. This docker image includes common versions of Unison server which can be selected with the UNISON_VERSION environment variable.

  • 2.40.102 (available via apt-get install unison on Ubuntu 14.04, 14.10, 15.04)
  • 2.48.3 (available via brew install unison on Mac OS X) [default]

Additional versions can be added easily on request. Open an Issue if you need another version.

Installing fswatch Locally

Get fswatch using brew install fswatch on Mac OS X otherwise download and compile from a release build.
