cronlocker is a commandline tool to allow running cronjobs on multiple hosts while ensuring that it only runs once at a time. cronlocker utilizes the consul lock feature to ensure that.
cronlocker can be easily executed by passing a key to lock as well as a command to be executed if the lock could be obtained successfully.
cronlocker -key=<key/to/lock> <command>
Use cronlocker --help to get the following output:
