Use the following information to help you diagnose and fix common issues that you might encounter when working with AWS IoT Greengrass and IAM.
Issues
For general troubleshooting help, see Troubleshooting AWS IoT Greengrass V2.
I'm not authorized to perform an action in AWS IoT Greengrass
If you receive an error that states you're not authorized to perform an action, you must contact your administrator for assistance. Your administrator is the person who provided you with your user name and password.
The following example error occurs when the mateojackson
IAM user
tries to view details about a core device, but does not have
greengrass:GetCoreDevice
permissions.
User: arn:aws:iam::123456789012:user/mateojackson is not authorized to perform: greengrass:GetCoreDevice on resource: arn:aws:greengrass:us-west-2:123456789012:coreDevices/MyGreengrassCore
In this case, Mateo asks his administrator to update his policies to allow him to
access the
arn:aws:greengrass:us-west-2:123456789012:coreDevices/MyGreengrassCore
resource using the greengrass:GetCoreDevice
action.
The following are general IAM issues that you might encounter when working with AWS IoT Greengrass.
I'm not authorized to perform iam:PassRole
If you receive an error that you're not authorized to perform the iam:PassRole
action, your policies must be updated to allow you to pass a role to AWS IoT Greengrass.
Some AWS services allow you to pass an existing role to that service instead of creating a new service role or service-linked role. To do this, you must have permissions to pass the role to the service.
The following example error occurs when an IAM user named marymajor
tries to use the console to perform an action in
AWS IoT Greengrass. However, the action requires the service to have permissions that are granted by a service role. Mary does not have permissions to pass the
role to the service.
User: arn:aws:iam::123456789012:user/
marymajor
is not authorized to perform: iam:PassRole
In this case, Mary's policies must be updated to allow her to perform the iam:PassRole
action.
If you need help, contact your AWS administrator. Your administrator is the person who provided you with your sign-in credentials.
I'm an administrator and want to allow others to access AWS IoT Greengrass
To allow others to access AWS IoT Greengrass, you must create an IAM entity (user or role) for the person or application that needs access. They will use the credentials for that entity to access AWS. You must then attach a policy to the entity that grants them the correct permissions in AWS IoT Greengrass.
To get started right away, see Creating your first IAM delegated user and group in the IAM User Guide.
I want to allow people outside of my AWS account to access my AWS IoT Greengrass resources
You can create an IAM role that users in other accounts or people outside of your organization can use to access your AWS resources. You can specify the who is trusted to assume the role. For more information, see Providing access to an IAM user in another AWS account that you own and Providing access to AWS accounts owned by third parties in the IAM User Guide.
AWS IoT Greengrass doesn't support cross-account access based on resource-based policies or access control lists (ACLs).
