I thought that by setting a attribute on every node then setting contraints like.. "constraints": [ ["exec_env", "GROUP_BY"], ["hostname", "UNIQUE"] ] If every node has the same 'exec_env' then they would all get one instance of this task ( i am not setting a value for 'instances' btw). What is a good way to be sure every slave has one of a particular task?
