func NewClusterWatcher ¶
func NewClusterWatcher(ctx context.Context,
managerOptions manager.Options,
retryOptions RetryOptions,
watchNamespaces []string) *clusterWatcher
NewClusterWatcher returns a *clusterWatcher, which watches for changes to kubeconfig secrets (which contain kubeconfigs for remote clusters).
- When ctx is cancelled, all cluster managers started by the clusterWatcher are stopped.
- Provided manager.Options are applied to all managers started by the clusterWatcher.
- RetryOptions specify how to retry manager creation if it fails. Any fields not explicitly provided in the retry options will take on the default values.
- If watchNamespaces is not empty, only secrets in the given namespaces will be watched. If empty, secrets in
all namespaces will be watched.
Types ¶
type RetryDelayType ¶ added in v0.26.2
type RetryDelayType int
RetryDelayType is the type of delay to be used for manager creation retries.
const (
// RetryDelayType_Backoff means retry with exponential backoff (with random jitter).
RetryDelayType_Backoff RetryDelayType = iota
// RetryDelayType_Fixed means retry at a fixed interval (with random jitter).
RetryDelayType_Fixed
)
type RetryOptions ¶ added in v0.26.2
type RetryOptions struct {
// DelayType is the type of retry delay (fixed or exponential backoff).
// Default is exponential backoff.
DelayType RetryDelayType
// Delay is the initial retry delay.
// Default is 1 second.
Delay *time.Duration
// MaxDelay is the maximum delay between retries.
// Default is 0 (no max).
MaxDelay *time.Duration
// MaxJitter is the maximum random jitter between retries.
// If set to 0, the delay intervals will contain no randomness.
// Default is the same value as delay (1 second).
MaxJitter *time.Duration
// Attempts is the maximum number of attempts.
// Default is 0 (retry forever).
Attempts *uint
}
RetryOptions specify how to retry when a manager fails to be created or started.
