     SSH_KEY             path to ssh private key that should be used (default ~/.ssh/id_rsa)
+
+## Use in production
+
+This example uses [panubo/sshd](https://github.com/panubo/docker-sshd), which seems well maintained enough. I would advise caution though as this is likely something that will have access to sensitive information.
+
+To be safe you should take precautions from someone logging into your server directly.  In my example, I'm using the following as my `authorized_keys` file:
+
+    no-pty,no-X11-forwarding,command="/bin/echo do-not-send-commands" ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDeG0iBsd5P9ZwDlav7mWaMGiq4SH5XvYGEGoZPgC3PjKgiEpe5lxH9p5lOFicqG7nNBaTwJwDPnJJaIIeHeCcpKF9f5RhTA5rwLkPcVIwZTh2GL7PD/yDmnsB1L8v04yTzjvJxHAi+xx+yN0fcxw2IOJ4k4FC1mNJKNwHZZHvzEyvRbC0GUB1K32dKSDUAWQHKx7xJqgtpkZ0DV78GzBfNUZcucImRwjQTBlJFumTjB5k0xUt0NRDLEkHwUMyiAeXB13tfjZipEHCWPxIrQnuwmV4Lb3VFbh8UqeObsarxG9t+SMoxnrKxQCAntcS0do1VjfiGr6usGVsV56ua8Tyj ifij@C02V7083HV2V
+
+This prevents getting a shell if my key is ever leaked.
+
+Additionally, if you are actually planning on doing this in production, do not use the `-insecure` flag in ./mole/start.sh`. Instead you should provide pre generated server keys and add those as known hosts for `mole`.
