Docker Unison - With Group ID

We extended the base image to also utilize unisons support for defining a sync GROUP_ID, because we had issues with file permissions.

The package currently uses unison 2.48.4.

Usage

This image is the unison-image for docker-sync and published on eugenmayer/unison A lot of credits go to mickaelperrin - most of the work has been done by him.

What does it do ?

This image simply runs an unison server on the internal port 5000 with the specified user/uid. If the user/uid doesn't exist, it is created/modified on startup.

Documetation

You can configure how unison runs by using the following ENV variables:

• VOLUME specifies the directory created in the container to store the synced files, /data by default
• OWNER_UID specifies the ID of the user on which the unison process run and the owner of the synced files.
• GROUP_ID specifies the ID of the group on which the unison process run and the group of the synced files.
• MAX_INOTIFY_WATCHES increases the limit of inotify watches if you need to sync folders with lots of files.

Credits

• Big thanks at mickaelperrin for putting hard work into getting this production ready
