Docker image for configured vsftpd

I made this image for people who, like me, needs a fast way to deploy a small ftp server. Each time you start a container, a small script inside generate a random user/password, create user account, apply password and make a new cert from openssl.

It's a very easy way to share temporarly one directory on your server. Do not use for long support !.

There is no guess, no public view and no anonymous. It use TLS to encrypt communications.

It's an update from this project with this article.

To get the user/pass, use docker logs.

Encryption	Passive Ports	Max clients
RSA 4096 bits	21000 to 21100	100

Run a container for example :

$ docker run -it --name ftp --rm -p 20-22:20-22 -p 990:990 -p 21000-21100:21000-21100 -v [local_dir]:/home/vsftpd image:tag

You will get somthing like this :

addgroup: group 'nogroup' in use
chpasswd: password for 'tpronf' changed
Generating a RSA private key
......................................................................................++++
........................................++++
writing new private key to '/etc/vsftpd/vsftpd.key'
-----
- User : tpronf
- Pass : gsmYl6I-7lqMLMA4ccQL

Have a good day !

If you use -d option, use docker logs [container_name] to get user/pass.

Binds

You can bind 2 folders between container and host :

• /home/vsftpd for files
• /var/log/vsftpd for logs

Be Careful !

The container has all rights on the files folder shared (chrooted for security). Users who have login/password can upload, create and delete all contents in it. Anonymous can't connect obviously.

Do not use this container to share readonly/public content !!

Arguments

In passive mode, vsftpd need sometimes an external IP to deal with. For that, use PASV_ADDRESS env. With command line, use -e "PASV_ADDRESS=X.X.X.X"

$ docker run -e "PASV_ADDRESS=1.2.3.4" image:tag

Official release

To get pre-build online version :
