SFTP Container

Container for managing data over sftp server.

Add user public key

There are two ways to setup public key

1. Set variable(s) SSH_CLIENT_someusername="ssh-ed25519 AAAAC3..." and /entrypoint will put it in user home authorized_keys for you
2. Mount authorized_keys directly to user home /var/www/

Connect to sftp server

Container uses precreated user www-data with chrooted home under /var/www/ directory. Directory is owned by root to be able to use ChrootDirectory sshd directive so you are not allowed to write anything directly in this directory.

See docker-compose.yaml sftp-test service in case you struggle with connection.
