• vsFtp: vsFTP Server based on CentOS
• Jenkins: Customized Jenkins based on official Jenkins which is based on Debian.
• OpenStack Swift: Operate the Object Storage service, Swift, from OpenStack in stand-alone mode.

Supervisord

• Many of these Docker containers use Supervisord for starting and running the daemons.
• Supervisord starts a daemon in the foreground and restarts the daemon if it stops.
