Simple rsync server based on Alpine To be able to connect to this rsync server you need to add the SSH key of your client to the variable SSH_AUTH_KEY_1 How to create an SSH key? Log into your client machine and create an SSH key as follows: ssh-keygen -t rsa -b 4096 Press 3x ENTER to use the default location and create the key without password. Now display your SSH Key with the following command: cat ~/.ssh/id_rsa.pub Copy the complete line like "ssh-rsa AAA.... username@client" and paste it in the field "SSH_AUTH_KEY_1" and start this container. You can test the connection from your client as follows (replace "tower" against your server name or domain): rsync --dry-run --itemize-changes --archive -e 'ssh -p 5533' root@tower:/mnt/user/system/ /tmp

Common questions

How do I allow a client to connect to the rsync server?

Add the client's public SSH key to the SSH_AUTH_KEY_1 environment variable when starting the server. Additional client keys can be added with SSH_AUTH_KEY_n variables.

Which port should the Docker server expose for SSH-based rsync?

The documented Docker example maps host port 2222 to container port 22. The client rsync command then uses ssh -p 2222.

Do I need to persist SSH keys when recreating the containers?

Yes, persist the client key directory /root/.ssh and the server host key directory /ssh_host_keys in Docker volumes. The keys are created on first start and reused on later starts.

What volume do I mount for the rsync data?

Mount the data directory to /data in the container. The examples use server_vol_to_sync for the server and client_vol_to_sync for the client.

Can I run the rsync transfer automatically?

Set CRON_TASK_1 or CRON_TASK_2 on the client container to a cron command. The example runs an rsync command over SSH at a scheduled time.
