Instance Attribute Details

#replacement_strategy ⇒ String? (readonly)

You are charged for all instances while they are running.

launch-before-terminate - EC2 Fleet launches a replacement Spot Instance when a rebalance notification is emitted for an existing Spot Instance in the fleet, and then, after a delay that you specify (in TerminationDelay ), terminates the instances that received a rebalance notification.

Returns:

  • (String, nil)
