  • When options are unspecified, the following defaults take effect:

const (
   defaultResyncPeriod                  = 15 * time.Second
   defaultExponentialBackOffOnError     = true
   defaultCreateProvisionedPVRetryCount = 5
   defaultCreateProvisionedPVInterval   = 10 * time.Second
   defaultFailedProvisionThreshold      = 15
   defaultFailedDeleteThreshold         = 15
   defaultLeaseDuration                 = 15 * time.Second
   defaultRenewDeadline                 = 10 * time.Second
   defaultRetryPeriod                   = 2 * time.Second
   defaultTermLimit                     = 30 * time.Second
)
