Use PutGroupPolicy with a CLI

To add a policy to a group

The following put-group-policy command adds a policy to the IAM group named Admins.

aws iam put-group-policy \
    --group-name Admins \
    --policy-document file://AdminPolicy.json \
    --policy-name AdminRoot

This command produces no output.

The policy is defined as a JSON document in the AdminPolicy.json file. (The file name and extension do not have significance.)

For more information, see Managing IAM policies in the AWS IAM User Guide.

Example 1: This example creates an inline policy named AppTesterPolicy and embeds it in the IAM group AppTesters. If an inline policy with the same name already exists, then it is overwritten. The JSON policy content comes the file apptesterpolicy.json. Note that you must use the -Raw parameter to successfully process the content of the JSON file.

Write-IAMGroupPolicy -GroupName AppTesters -PolicyName AppTesterPolicy -PolicyDocument (Get-Content -Raw apptesterpolicy.json)
