jusito/rsync-ssh repository overview

⁠docker-rsync-ssh-alpine

This container allows rsync over ssh with public key usage. This is mainly a tool for myself, but maybe you need it too.

⁠example with public key and passphrase

  1. Set your key passphrase -e KEY_PASSPHRASE=YourKeyPassword
  2. Set valid known_hosts entry -e KNOWN_HOSTS="sub.domain.com,123.45.67.8 exdsa-sha2-xxx ..."
  3. Mount your private key file -v /home/user/backup/backup.priv:/root/key:ro
  4. Mount data you want to sync -v /home/user/backup/data:/home/data:ro
  5. Define rsync command rsync -altDv --delete -e 'ssh -i /root/.ssh/id_rsa' "/home/data" sub.domain.com:/data
docker run -ti --rm --name backup \
 -e KEY_PASSPHRASE=YourKeyPassword -e KNOWN_HOSTS="sub.domain.com,123.45.67.8 exdsa-sha2-nistp256 ..." \
 -v /home/user/backup/backup.priv:/root/key:ro \
 -v /home/user/backup/data:/home/data:ro \
