GameLift Unreal Plugin -- Bootstrap Profile FAILED "Access Denied" for IAM User

Question

I have the Unreal Gamelift plugin for AWS integrated. I am able to setup my user with AdministratorAccess + GameLiftGameServerGroupPolicy successfully, but I cannot find any information on how to setup additional users so my co-developers can bootstrap and connect to my Anywhere server.
I created a new IAM user with GameLiftGameServerGroupPolicy attached, but I get the following error when bootstrapping: **Account Invalid GameLiftCoreLog: Warning: AWSBootstrapProfile: Unable to create AWS credentials profile with an error:  GAMELIFT ERROR GENERAL**

Additionally, when I generate access keys and share them with co-developers, it says that the account can't even be found. If someone could point me to a tutorial/documentation on how to properly setup IAM users for other developers to connect to my Anywhere server that would be great. I am able to successfully deploy my server to EC2, and I can connect locally to my Anywhere server.

Answer

Hey mmakivic,

Firstly, GameLiftGameServerGroupPolicy is a managed policy meant to ease developer integration with Amazon GameLift's FleetIQ product (aka GameServerGroups): https://docs.aws.amazon.com/gamelift/latest/fleetiqguide/gsg-intro.html. This product is not tied to the main Amazon GameLift product of Fleets that the Amazon GameLift Plugin for Unreal demonstrates.

The actions to give access to your co-developers depends on what you want them to be able to do:
* You'll need to grant them `gamelift:DescribeGameSessions` and `gamelift:CreatePlayerSession` permissions so they can find existing game sessions and connect to them.
* If you would like them to create their own game sessions on your Anywhere fleet, you'll also need to grant them `gamelift:CreateGameSession` permissions.

Additionally, if you've created an Anywhere fleet and are running the server yourself, your co-developers shouldn't need to use the editor at all and can directly use the client executable you've built. The GameLift Plugin for Unreal client looks for AWS credential profiles like the AWS CLI, so you can reference their documentation for developers to setup their profiles manually: https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-files.html . Here's a snippet for reference:
```
# In ~/.aws/credentials file
[my_custom_user]
aws_access_key_id=ABCDEFGHIJKLMEXAMPLE
aws_secret_access_key=abcdefghijkl/0123456/mnopqrstuEXAMPLEKEY
region=us-east-1 # AWS region you created the Anywhere fleet in
```

Lastly, if you'd like to look at the source code, this file handles the anywhere fleet connection logic: https://github.com/aws/amazon-gamelift-plugin-unreal/blob/main/GameLiftPlugin/Source/GameLiftClient/Private/UI/TestAnywhereMenuWidget.cpp

Hope that helps!
