Hetman¶

Hetman is an automation tool dedicated for teams that need to get rid of manual scheduling and monitoring execution of tasks or groups of tasks. Tasks could be any scripts, programs or containers triggered and monitored.

In HA Load Balancer Hetman is responsible for scheduling and running the Cluster Manager algorithm.

In the following chapters ${node_ip} variable can be replaced with:

• Primary Cluster Manager IP,
• Secondary Cluster Manager IP.
