-- | Creates a value of 'SendCommand' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'scServiceRoleARN' - The IAM role that Systems Manager uses to send notifications.
--
-- * 'scNotificationConfig' - Configurations for sending notifications.
--
-- * 'scDocumentHashType' - Sha256 or Sha1.
--
-- * 'scOutputS3KeyPrefix' - The directory structure within the S3 bucket where the responses should be stored.
--
-- * 'scMaxErrors' - The maximum number of errors allowed without the command failing. When the command fails one more time beyond the value of @MaxErrors@ , the systems stops sending the command to additional targets. You can specify a number like “10” or a percentage like “10%”. The default value is 50. For more information about how to use @MaxErrors@ , see <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/run-command.html Executing a Command Using Amazon EC2 Run Command> (Linux) or <http://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/run-command.html Executing a Command Using Amazon EC2 Run Command> (Windows).
--
-- * 'scInstanceIds' - Required. The instance IDs where the command should execute. You can specify a maximum of 50 IDs.
--
-- * 'scOutputS3Region' - (Optional) The region where the Amazon Simple Storage Service (Amazon S3) output bucket is located. The default value is the region where Run Command is being called.
--
-- * 'scTargets' - (Optional) An array of search criteria that targets instances using a @Key@ ;@Value@ combination that you specify. @Targets@ is required if you don't provide one or more instance IDs in the call. For more information about how to use @Targets@ , see <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/run-command.html Executing a Command Using Amazon EC2 Run Command> (Linux) or <http://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/run-command.html Executing a Command Using Amazon EC2 Run Command> (Windows).
--
-- * 'scParameters' - The required and optional parameters specified in the SSM document being executed.
--
-- * 'scDocumentHash' - The Sha256 or Sha1 hash created by the system when the document was created.
--
-- * 'scTimeoutSeconds' - If this time is reached and the command has not already started executing, it will not execute.
--
-- * 'scComment' - User-specified information about the command, such as a brief description of what the command should do.
--
-- * 'scOutputS3BucketName' - The name of the S3 bucket where command execution responses should be stored.
--
-- * 'scMaxConcurrency' - (Optional) The maximum number of instances that are allowed to execute the command at the same time. You can specify a number such as “10” or a percentage such as “10%”. The default value is 50. For more information about how to use @MaxConcurrency@ , see <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/run-command.html Executing a Command Using Amazon EC2 Run Command> (Linux) or <http://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/run-command.html Executing a Command Using Amazon EC2 Run Command> (Windows).
--
-- * 'scDocumentName' - Required. The name of the SSM document to execute. This can be an SSM public document or a custom document.
