An image based on OpenWrt x86_64 which runs a ftp server.

The simplest case is to specify user name and password when starting the container:

docker run -p 11021:21 -it --rm -e FTP_USER=scott -e FTP_PASS=tiger -e HOST=publicname.example.com mcreations/openwrt-ftp

Note that HOST signifies the name or IP with which the docker container can be reached from clients, usually the public IP or name of the docker host where the container is started.

Now, you can ftp to this docker instance with

ftp publicname.example.com 11021

The default configuration uses passive ports from 65000 to 65100. If you need to publish a specific port range on your host, you can narrow down the range with the environment variables PASV_MIN_PORT and PASV_MAX_PORT:

docker run -it --rm \
            -p 11021:21 \
            -e FTP_USER=scott -e FTP_PASS=tiger -e HOST=myserver.domain.com \
            -p 65000-65004:65000-65004 \
            -e PASV_MIN_PORT=65000 -e PASV_MAX_PORT=65004 \
            mcreations/ftp

Here, the PASV_MIN_PORT variable could be omitted as it defaults to 65000.
