Configure heartbeat cron

The heartbeat cronjob must be configured and executed as the most important part of Pacemaker.

The heartbeat performs the condition checks for pipelines that are ready for completion and initiates them
At the same time, the heartbeat checks conditions for steps within existing pipelines and triggers execution, when a step is ready for execution

Default configuration

By default, you should create a new crontab entry within your OS as follows:

This configuration will run the heartbeat every minute

* * * * *  /usr/bin/env php <PATH_TO_MAGENTO_ROOT>/bin/magento pipeline:heartbeat

Another heartbeat interval example

If you need to run the heartbeat less often than every minute, you need to define the pulse to avoid time gaps within time-based conditions.

See Process Pipelines - Step conditions

For example, for a heartbeat, which is running every two minutes:

*/2 * * * *  /usr/bin/env php <PATH_TO_MAGENTO_ROOT>/bin/magento pipeline:heartbeat --pulse 2
