rsync-server

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

Quickstart

Start a server (both sshd and rsyncd are supported)

docker run \
    --name rsync-server \
    -p 8000:873 \
    -p 9000:22 \
    -e USERNAME=user \
    -e PASSWORD=someSecurePassword_NOT_THIS \
    -v /your/public.key:/root/.ssh/authorized_keys \
    axiom/rsync-server:latest

You must set a password via PASSWORD or PASSWORD_FILE, even if you are using key authentication.

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

Simple server on port 873

docker run -p 873:873 -e PASSWORD=changeme axiom/rsync-server:latest

Use a volume for the default /data

docker run -p 873:873 -e PASSWORD=seriouslychangeme -v /your/folder:/data axiom/rsync-server:latest

Set a username and password

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

Set password via file

docker run \
    -p 873:873 \
    -v /your/folder:/data \
    -v ./password-file-with-secure-permissions:/etc/rsyncd/password:ro \
    -e USERNAME=admin \
    -e PASSWORD_FILE=/etc/rsyncd/password \
    axiom/rsync-server:latest

Run on a custom port

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

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=yougetitnow \
    -e VOLUME=/myvolume \
    axiom/rsync-server:latest

rsync rsync://admin@localhost:9999

volume            /myvolume directory

Allow specific client IPs

docker run \
    -p 9999:873 \
    -v /your/folder:/myvolume \
    -e USERNAME=admin \
    -e PASSWORD=hopesoanyway \
    -e VOLUME=/myvolume \
    -e ALLOW=192.168.24.0/24 \
    axiom/rsync-server:latest

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. This file must have owner root, group root, and 400 octal permissions.

Alternatively, you may specify the AUTHORIZED_KEYS environment variable.

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=2manyp455w0rd5 \
    -e VOLUME=/myvolume \
    -e ALLOW=10.0.0.0/8 192.168.0.0/16 172.16.0.0/12 127.0.0.1/32 \
    -v /my/authorized_keys:/root/.ssh/authorized_keys \
    -p 9000:22 \
    axiom/rsync-server:latest

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