Enables Leader Migration for
|
|
[kube-controller-manager](/docs/tasks/administer-cluster/controller-manager-leader-migration/#initial-leader-migration-configuration) and
|
|
[cloud-controller-manager](/docs/tasks/administer-cluster/controller-manager-leader-migration/#deploy-cloud-controller-manager)
|
|
which allows a cluster operator to live migrate
|
|
controllers from the kube-controller-manager into an external controller-manager
|
|
(e.g. the cloud-controller-manager) in an HA cluster without downtime.
|
|
-->
|
|
为 [kube-controller-manager](/zh-cn/docs/tasks/administer-cluster/controller-manager-leader-migration/#initial-leader-migration-configuration)
|
|
和 [cloud-controller-manager](/zh-cn/docs/tasks/administer-cluster/controller-manager-leader-migration/#deploy-cloud-controller-manager)
|
|
启用 Leader 迁移，它允许集群管理者在没有停机的高可用集群环境下，实时把 kube-controller-manager
|
|
迁移到外部的 controller-manager (例如 cloud-controller-manager) 中。
