    • ssmSessionPermissions

      @Stability(Stable) public Instance.Builder ssmSessionPermissions(Boolean ssmSessionPermissions)
      Add SSM session permissions to the instance role.

      Setting this to true adds the necessary permissions to connect to the instance using SSM Session Manager. You can do this from the AWS Console.

      NOTE: Setting this flag to true may not be enough by itself. You must also use an AMI that comes with the SSM Agent, or install the SSM Agent yourself. See Working with SSM Agent in the SSM Developer Guide.

      Default: false

    • 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.
      Returns:
      this
