⁠Agent Specific Configuration

These are additional specific configuration options for this agent. Global agent configurations⁠ still apply.

1. AWS Regions as returned by the AWS SDK at runtime for Lambda.

⁠AWS Authentication

As this requires access to the AWS API you will need this IAM policy as a minimum for it to operate correctly.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
              "lambda:ListFunctions"
            ],
            "Resource": "*",
            "Effect": "Allow"
        }
    ]
}

We recommend using EC2/ECS Task roles so that you don't need to send credentials into the container, however if you can't use those or want to send in specific Access Keys and Secret keys, please see the AWS Documentation⁠ as to how you do that.

⁠Cross-Account Authentication (STS AssumeRole)

If you run Garrison agents in one account, and want to reach into other AWS accounts you need to send in extra environmental variables to support that.
