# 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 -avz 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 -o StrictHostKeyChecking=no' -avz 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="<SSH KEY FROM rsync_client>" \
|
|
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 -o StrictHostKeyChecking=no' -avz root@foo.bar.com:/data/ /data/
|
|
$ ls -l /data/
