ftp-docker
This is a docker container to launch vsftpd. It comes with 4 pre-defined configuration :
- ftp : FTP
- ftps : FTPS explicit
- ftps_implicit : FTPS implicit
- ftps_tls : FTPS explicit with high cypher (ssl_ciphers=HIGH)
To build it:
docker build -t ftp/docker:latest https://github.com/sylvinho81/ftp-docker.git --build-arg USER=admin --build-arg PASS=admin
To use it : docker run -p <host_port>:21 ftp/docker <configuration_name>
docker run -p 21:21 ftp/docker ftp
PASV is enabled, to use it you need to specify the PASV_ADDRESS env variable pointing to the IP address of the host when launching the container and mapping the ports range 21100-21110:
docker run -p 21:21 -p21100-21110:21100-21110 --env PASV_ADDRESS=x.x.x.x ftp/docker ftp
For FTPS configurations, by default, PEM and PKCS-12 certificate keystore files are generated to /etc/vsftpd/private
location and are used by FTPS server. You can provide your own certificate keystore file, instead, by passing volume
to docker run command. For example, below command will have FTPS server use the provided certificate keystore PEM file
found at /tmp/my_pem_file_dir on the host machine. Make sure the file is named as vsftpd.pem.
docker run --volume "/tmp/my_pem_file_dir:/etc/vsftpd/private" ftp/docker ftps
Two volumes are defined :
- /home/{user} : the FTP data directory of the user (the only available by default)
- /var/log/vsftpd : the log directory
