anon-ftp: An quick, anonymous ftp server docker image
This image is meant for running something like a public read-only share. User accounts are not supported and all data access is meant to be read only via ftp anonymous login.
Up-and-Running
View my included docker-compose.yml for a runtime configuration example or check the below one-liner for a quick launch!
docker run -d -p 20-21:20-21 -p 65500-65515:65500-65515 -v /tmp:/var/ftp:ro metabrainz/docker-anon-ftp

Notes
- Ensure you use :ro at the end of your bind mount declaration!
- We utilize ftp passive mode so we can define the ports we need and not have to use
--net=host. This is the preferred way to use ftp! - You can find some great documentation on configuration options and other vsftpd information on the Archwiki and in the man page
