[ aws . emr ]

create-default-roles

Description

Creates the default IAM role EMR_EC2_DefaultRole and EMR_DefaultRole which can be used when creating the cluster using the create-cluster command. The default roles for EMR use managed policies, which are updated automatically to support future EMR functionality.

If you do not have a Service Role and Instance Profile variable set for your create-cluster command in the AWS CLI config file, create-default-roles will automatically set the values for these variables with these default roles. If you have already set a value for Service Role or Instance Profile, create-default-roles will not automatically set the defaults for these variables in the AWS CLI config file. You can view settings for variables in the config file using the "aws configure get" command.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .
