Constructors
Section titled “Constructors”FailurePolicy(StartupFailureBehavior, StopFailureBehavior, bool, int, TimeSpan, TimeSpan, TimeSpan)
Section titled “ FailurePolicy(StartupFailureBehavior, StopFailureBehavior, bool, int, TimeSpan, TimeSpan, TimeSpan)”Initializes a new instance of the
public FailurePolicy(StartupFailureBehavior startupFailureBehavior = StartupFailureBehavior.FailFast, StopFailureBehavior stopFailureBehavior = StopFailureBehavior.BestEffortContinue, bool allowManualRestart = true, int maxRestartAttempts = 3, TimeSpan startupReadinessDelay = default, TimeSpan shutdownLivenessGracePeriod = default, TimeSpan manualRestartBackoff = default)Parameters
Section titled “Parameters”startupFailureBehavior StartupFailureBehavior
How startup failures are handled.
stopFailureBehavior StopFailureBehavior
How stop failures are handled.
allowManualRestart bool
Whether operators can manually restart the runtime after supported failures.
maxRestartAttempts int
The maximum number of manual restarts, where -1 allows unlimited restarts.
startupReadinessDelay TimeSpan
The optional warmup window that keeps readiness unhealthy after startup succeeds.
shutdownLivenessGracePeriod TimeSpan
The optional drain window that keeps liveness healthy while shutdown is in progress.
manualRestartBackoff TimeSpan
The optional backoff window that delays manual restarts after a restartable failure.
