Full Description

Simple rsync container based on alpine

A simple rsync server/client Docker image to easily rsync data within Docker volumes

Simple Usage

Get files from remote server within a docker volume:

$ docker run --rm -v blobstorage:/data/ eeacms/rsync \
         rsync -avzx --numeric-ids user@remote.server.domain.or.ip:/var/local/blobs/ /data/

Get files from remote server to a data container:

$ docker run -d --name data -v /data busybox
$ docker run --rm --volumes-from=data eeacms/rsync \
         rsync -avz user@remote.server.domain.or.ip:/var/local/blobs/ /data/

Advanced Usage

Client setup

Start client to pack and sync every night:

$ docker run --name=rsync_client -v client_vol_to_sync:/data \
             -e CRON_TASK_1="0 1 * * * /data/pack-db.sh" \
             -e CRON_TASK_2="0 3 * * * rsync -e 'ssh -p 2222' -aqx --numeric-ids root@foo.bar.com:/data/ /data/" \
         eeacms/rsync client

Copy the client SSH public key printed found in console

Server setup

Start server on foo.bar.com

# docker run --name=rsync_server -d -p 2222:22 -v server_vol_to_sync:/data \
             -e SSH_AUTH_KEY_1="<SSH KEY FROM rsync_client>" \
             -e SSH_AUTH_KEY_n="<SSH KEY FROM rsync_client_n>" \
         eeacms/rsync server

Verify that it works

Add test file on server:

$ docker exec -it rsync_server sh
  $ touch /data/test

Bring the file on client:

$ docker exec -it rsync_client sh
  $ rsync -e 'ssh -p 2222' -avz root@foo.bar.com:/data/ /data/
  $ ls -l /data/
