In some situations, primarily with automated deployments, it makes sense to install curator on every node. But you wouldn’t want it to run on each node. With the --master-only flag, this is possible. It tests for, and will only continue running on the node that is the elected master.


  • --master-only Only operate on elected master node.

This flag must come before any command.


Operate only on the master node:

curator --master-only <<command>> <<flags>>
