best way would be to use some sort of shared cache (like redis) to store the state for a period of time. For example, cron A from service 1 will set a key "cron_a_running" with a certain lifetime. The cron function should successfully finish (and remove the key) OR fail (and the key will live until expiration or until manually remove). The same cron A running from service 2 will check said key in redis and skip an execution if the key is there.
not a perfect solution - but this is just a simple cron manager and while I'm not part of the project, a system of clustering feels out of scope.
from cron.
Just have a global variable and check if it's "true" when the function starts and set it to true immediately faster
You're running multiple programs with the same cron jobs? that isn't what cron is for lol
