Simple rsync server running in a docker container
This is inspired by https://github.com/nabeken/docker-volume-container-rsync and https://github.com/bfosberry/rsync
Launch the container via docker:
docker run -d -p <port>:873 --name rsyncd darkdragon001/rsyncd
You can connect to the rsync server you just created with:
rsync rsync://<docker>:<port>/
volume volume
To sync:
rsync -avP /path/to/dir rsync://<docker>:<port>/volume/
Some variables can be customized :
To set the name of the sync volume. Default is "volume"
Example :
docker run -d -p <port>:873 --name rsyncd \
-e VOLUME="backup" \
darkdragon001/rsyncd
which will give :
rsync rsync://<docker>:<port>/
backup backup
By default, volumes are exposed without password. If you want users to authenticate use this.
Example :
docker run -d -p <port>:873 --name rsyncd \
-e USERS="user1:password1,user2:password2" \
darkdragon001/rsyncd
By default, volumes are exposed read-write. If you want to protect them read-only, set the environment variable.
Example :
docker run -d -p <port>:873 --name rsyncd \
-e READONLY="true" \
darkdragon001/rsyncd
By default, rsync server accepts a connection only from 192.168.0.0/16
, 172.12.0.0/12
and 10.0.0.0/8
for security reasons.
You can override via an environment variable like this:
docker run -d -p <port>:873 \
--name rsyncd \
-e ALLOW='10.0.0.0/8 x.x.x.x/y' \
darkdragon001/rsyncd
By default the user "nobody" is used. You can customize and pass the id of a user the docker host (so that file perms are correct). Example, if your docker host has a user "ubuntu" with id 1000 you can use :
docker run -d -p <port>:873 \
--name rsyncd \
-e OWNER=1000 \
darkdragon001/rsyncd
Files created in the volume by rsyncd will belong to the user ubuntu (see volumes below).
By default the group "nogroup" is used. You can also customize and pass the id of a group on the docker host. Example, if your docker host has a group "users" with id 100 you can use :
docker run -d -p <port>:873 \
--name rsyncd \
-e GROUP=100 \
darkdragon001/rsyncd
Files created in the volume by rsyncd will belong to the group users.
The sync folder exposed by rsyncd is a docker volume. You can map it to a local folder on the docker host : Example, if your docker host has a user "ubuntu" with id 1000 you can use :
docker run -d -p <port>:873 \
--name rsyncd \
-v /path/to/host/folder:/volume \
darkdragon001/rsyncd
docker run -d -p 873:873 \
--name rsyncd \
-e VOLUME="backup" \
-e OWNER=1000 \
-e GROUP=100 \
-v /srv/backup:/volume \
darkdragon001/rsyncd
This will start an rsync daemon, exposed on the standard port, with a volume named "backup", and map it to the host folder /srv/backup. Files created during sync will belong to user "ubuntu" and group "users" on a standard Ubuntu install.
