vsftpd

Docker image for running a vsftpd container using virtual users, based on the excellent work at fauria / docker-vsftpd Check that solution for a detailed list of settings that can be applied to this image at runtime.

The main differences are that this solution attempts to build on docker-vsftpd to allow permanent storage of users / data on volumes which persists across the lifecycle of the container.

SECURITY WARNING: FTP is not a secure protocol and 'crypt' is not a secure function by today's standards. If you want robust security around your users and data, do not use vsftpd and opt for a sftp-based solution where strong encryption and key-based authentication can be implemented.

This is definitely a "use-at-your-own-risk" solution, primarily done as an exercise, and I accept no liability for the security of your data if you implement this solution :)
