func (*LeaderElector) StartCoordination

func (l *LeaderElector) StartCoordination(agentNameSpace string) error

StartCoordination starts scheduling of leader elector coordination between Instana Agents.

Agent Coordination works by requesting the "resources" for which an Agent would be leader. This could be one or more. Different Agents might request similar or different "resources".

The Operator should, for every requested resource, appoint one specific Agent pod as leader by calling the /coordination/assigned endpoint.

type LeadershipStatus struct {
	Status map[string]*coordination_api.CoordinationRecord
}
