IAM 角色未分配实例配置文件

Question

I'm trying to export my table from DynamoDB to S3. Following the documentation here I created the two roles needed for the pipeline, DataPipelineDefaultRole and DataPipelineDefaultResourceRole. After trying to execute the pipeline, I discovered that my DataPipelineDefaultRole was not created with an instance profile.

I've been looking through forums and Amazon says that people receive errors like this when they create their IAM Roles through the CLI. Their recommendation is to create the roles through the console and then the instance profile will be attached to the roll automatically. I'm creating the role through the console but for the DataPipelineDefaultRole, there is no instance profile attached?

Is there a way to manually attach an instance profile? Or am I missing something that is causing this to not auto-generate?

Answer 1

This might help:

https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-ec2_instance-profiles.html

It highlights info about instance profiles and namely how to create if you already have existing roles etc. I think this might be what you're looking for.

ie .

aws iam create-instance-profile --instance-profile-name DataPipelineDefaultRole

then

aws iam add-role-to-instance-profile --role-name DataPipelineDefaultRole --instance-profile-name DataPipelineDefaultRole

Answer 2

I have test the solution by Liam and it's working fine.

aws iam create-instance-profile --instance-profile-name DataPipelineDefaultRole

aws iam add-role-to-instance-profile add-role-to-instance-profile --role-name DataPipelineDefaultRole --instance-profile-name DataPipelineDefaultRole 

and there typo on the command provided should not repeat aws I am again.
