Running the Curator

To run the curator simply invoke the djinn-curator binary. There are only two flags that can be given to the djinn-curator binary,

  • -config - This specifies the configuration file to use, by default this will be djinn-curator.conf.

  • -limit - This specifies the limit in bytes to use for clearing up artifacts, by default this will be set to 1073741824 (1GB).

Configuring the Curator Daemon

The dist directory contains files for running the Djinn Curator as a daemon on Linux systems that use systemd and SysVinit for daemon management. Use whichever suits your needs, and modify accordingly.

If deploying to a Linux system that uses systemd, then be sure to run systemctl daemon-reload upon placement of the service file.
