Restricted SSH server which allows SCP / SFTP access only.

Running

1. Put your authorized keys in an ENV variable and run the image:

   AUTHORIZED_KEYS=$(base64 -w0 my-authorized-keys)
   
   docker run -d \
     -e AUTHORIZED_KEYS=$AUTHORIZED_KEYS \
     -p <PORT>:22 \
     -v <DATADIR>:/home/data \
     -v <HOSTKEYDIR>:/var/local/etc/ssh \
     schoolscout/scp-server

   Alternatively, mount your authorized_keys file into the container at /run/secrets/authorized_keys:

   docker run -d \
     -v /path/to/my/authorized_keys:/run/secrets/authorized_keys \
     -p <PORT>:22 \
     -v <DATADIR>:/home/data \
     -v <HOSTKEYDIR>:/var/local/etc/ssh \
     schoolscout/scp-server

2. Now you can copy into the container (e.g. via scp) as the data user:

   scp -P <PORT> <FILE> data@<DOCKER-HOST>:
