rsync-server

A rsyncd/sshd server in Docker. You know, for moving files.

tl;dr

Start a server (both sshd and rsyncd are supported)

$ docker run \
    --name rsync-server \ # Name it
    -p 8000:873 \ # rsyncd port
    -p 9000:22 \ # sshd port
    -e USERNAME=user \ # rsync username
    -e PASSWORD=pass \ # rsync/ssh password
    -v /your/public.key:/root/.ssh/authorized_keys \ # your public key
    axiom/rsync-server

rsyncd

Please note that /volume is the rsync volume pointing to /data. The data will be at /data in the container. Use the VOLUME parameter to change the destination path in the container. Even when changing VOLUME, you will still rsync to /volume.

$ rsync -av /your/folder/ rsync://user@localhost:8000/volume
Password: pass
sending incremental file list
./
foo/
foo/bar/
foo/bar/hi.txt

sent 166 bytes  received 39 bytes  136.67 bytes/sec
total size is 0  speedup is 0.00

sshd

Please note that you are connecting as the root and not the user specified in the USERNAME variable. If you don't supply a key file you will be prompted for the PASSWORD.

$ rsync -av -e "ssh -i /your/private.key -p 9000 -l root" /your/folder/ localhost:/data
sending incremental file list
./
foo/
foo/bar/
foo/bar/hi.txt

sent 166 bytes  received 31 bytes  131.33 bytes/sec
total size is 0  speedup is 0.00

Advanced Usage

Variable options (on run)

• USERNAME - the rsync username. defaults to user
• PASSWORD - the rsync password. defaults to pass
• VOLUME - the path for rsync. defaults to /data
• ALLOW - space separated list of allowed sources. defaults to 192.168.0.0/16 172.16.0.0/12.

Simple server on port 873

$ docker run -p 873:873 axiom/rsync-server

Use a volume for the default /data

$ docker run -p 873:873 -v /your/folder:/data axiom/rsync-server

Set a username and password

$ docker run \
    -p 873:873 \
    -v /your/folder:/data \
    -e USERNAME=admin \
    -e PASSWORD=mysecret \
    axiom/rsync-server

Run on a custom port

$ docker run \
    -p 9999:873 \
    -v /your/folder:/data \
    -e USERNAME=admin \
    -e PASSWORD=mysecret \
    axiom/rsync-server

$ rsync rsync://admin@localhost:9999
volume            /data directory

Modify the default volume location

$ docker run \
    -p 9999:873 \
    -v /your/folder:/myvolume \
    -e USERNAME=admin \
    -e PASSWORD=mysecret \
    -e VOLUME=/myvolume \
    axiom/rsync-server

$ rsync rsync://admin@localhost:9999
volume            /myvolume directory

Allow additional client IPs

$ docker run \
    -p 9999:873 \
    -v /your/folder:/myvolume \
    -e USERNAME=admin \
    -e PASSWORD=mysecret \
    -e VOLUME=/myvolume \
    -e ALLOW=192.168.8.0/24 192.168.24.0/24 172.16.0.0/12 127.0.0.1/32 \
    axiom/rsync-server

Over SSH

If you would like to connect over ssh, you may mount your public key or authorized_keys file to /root/.ssh/authorized_keys.

Without setting up an authorized_keys file, you will be propted for the password (which was specified in the PASSWORD variable).

Please note that when using sshd you will be specifying the actual folder destination as you would when using SSH. On the contrary, when using the rsyncd daemon, you will always be using /volume, which maps to VOLUME inside of the container.

docker run \
    -v /your/folder:/myvolume \
    -e USERNAME=admin \
    -e PASSWORD=mysecret \
    -e VOLUME=/myvolume \
    -e ALLOW=192.168.8.0/24 192.168.24.0/24 172.16.0.0/12 127.0.0.1/32 \
    -v /my/authorized_keys:/root/.ssh/authorized_keys \
    -p 9000:22 \
    axiom/rsync-server

$ rsync -av -e "ssh -i /your/private.key -p 9000 -l root" /your/folder/ localhost:/data
