    • userDataCausesReplacement

      @Stability(Stable) public Instance.Builder userDataCausesReplacement(Boolean userDataCausesReplacement)
      Changes to the UserData force replacement.

      Depending the EC2 instance type, changing UserData either restarts the instance or replaces the instance.

      • Instance store-backed instances are replaced.
      • EBS-backed instances are restarted.

      By default, restarting does not execute the new UserData so you will need a different mechanism to ensure the instance is restarted.

      Setting this to true will make the instance's Logical ID depend on the UserData, which will cause CloudFormation to replace it if the UserData changes.

      Default: - true iff `initOptions` is specified, false otherwise.

      Parameters:
      userDataCausesReplacement - Changes to the UserData force replacement. This parameter is required.
