type ManagerOptions ¶
type ManagerOptions struct { // LeaderElection is whether leader election is turned on or not. LeaderElection bool // LeaderElectionResourceLock is the resource type used for leader election (defaults to `configmapsleases`). // // When changing the default resource lock, please make sure to migrate via multilocks to // avoid situations where multiple running instances of your controller have each acquired leadership // through different resource locks (e.g. during upgrades) and thus act on the same resources concurrently. // For example, if you want to migrate to the "leases" resource lock, you might do so by migrating // to the respective multilock first ("configmapsleases" or "endpointsleases"), which will acquire // a leader lock on both resources. After one release with the multilock as a default, you can // go ahead and migrate to "leases". Please also keep in mind, that users might skip versions // of your controller, so at least add a flashy release note when changing the default lock. // // Note: before controller-runtime version v0.7, the resource lock was set to "configmaps". // Please keep this in mind, when planning a proper migration path for your controller. LeaderElectionResourceLock string // LeaderElectionID is the id to do leader election with. LeaderElectionID string // LeaderElectionNamespace is the namespace to do leader election in. LeaderElectionNamespace string // WebhookServerHost is the host for the webhook server. WebhookServerHost string // WebhookServerPort is the port for the webhook server.
