dockerfiles/pure-ftpd

Pure-FTPd is a free (BSD), secure, production-quality and standard-conformant FTP server. It doesn't provide useless bells and whistles, but focuses on efficiency and ease of use. It provides simple answers to common needs, plus unique useful features for personal users as well as hosting providers.

~/fig/pureftpd/docker-compose.yml

pureftpd:
  image: vimagick/pure-ftpd
  ports:
    - "21:21"
  volumes:
    - ftpuser:/home/ftpuser
    - pure-ftpd:/etc/pure-ftpd
  privileged: true
  restart: always

We only need to expose port 21 to accept client ftp connection. Pure-FTPd will open random port to accept client ftp-data connection. At this time, host machine is a router for DNAT.
