Minimal IAM policy for installer to provision resources - Amazon IoT Greengrass
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Minimal IAM policy for installer to provision resources

When you install the Amazon IoT Greengrass Core software, you can provision required Amazon resources, such as an Amazon IoT thing and an IAM role for your device. You can also deploy local development tools to the device. The installer requires Amazon credentials so that it can perform these actions in your Amazon Web Services account. For more information, see Install the Amazon IoT Greengrass Core software.

The following example policy includes the minimum set of actions that the installer requires to provision these resources. These permissions are required if you specify the --provision argument for the installer. Replace account-id with your Amazon Web Services account ID, and replace GreengrassV2TokenExchangeRole with the name of the token exchange role that you specify with the --tes-role-name installer argument.

Note

The DeployDevTools policy statement is required only if you specify the --deploy-dev-tools argument for the installer.
