vsftpd
======

[vsftpd][1] is a GPL licensed FTP server for UNIX systems, including Linux.
It is secure and extremely fast. It is stable. Don't take my word for it, though.

## docker-compose.yml

```yaml
vsftpd:
  image: vimagick/vsftpd
  ports:
    - "21:21"
  volumes:
    - ./ftp:/var/lib/ftp
  privileged: true
  restart: always
```

## Server

$ cd ~/fig/vsftpd/
$ docker-compose up -d
$ touch ./ftp/README.md
$ docker exec -it vsftpd_vsftpd_1 sh

> :warning: Default password for `root` is empty, please change it!
> I also add another local user called `kev` here.
> You can edit [/etc/vsftpd/vsftpd.conf][2] to enable more functions.
