docker-alpine-ftp-server-tls

Small and flexible docker image with vsftpd server with tls

Important Note

I think upstream has made it more complicated than it needs to be since this commit and I'm not merging its commits anymore, although I cherry-pick some of them when I see fit.

ALERT

Do not use this certificate in your production server, you should generate your own certificate using this command openssl req -x509 -nodes -days 7300 -newkey rsa:2048 -keyout vsftpd.pem -out vsftpd.pem

The image gets big if we add openssl and generate certificate inside container, but it will be easy on host to generate a new certificate.
