## Deploy game-server autopilot server
Gameserver autopilot includes a server and client components. The server comprises of the endpoint deployed via SageMaker Inference, DynamoDB table to persist history of inferences, and an API gateway and Lambda function (http://tbd/) to simplify SageMaker runtime semantics. The [autopilot client](../ap-client) is deployed as a Kubernetes Pod that queries the autopilot server for the number of game-server needed to be launched for the next 10 minutes.

This step can be executed after the model training complete and the model is deployed and available through a SageMaker Inference Endpoint. i.e., after completing [Model Deployment](https://github.com/yahavb/amazon-sagemaker-examples/tree/master/reinforcement_learning/rl_game_server_autopilot/sagemaker/rl_gamerserver_ray.ipynb#Model-deployment). The game-server autopilot server runs a lambda function behind API gateway. We use [Chalice](https://chalice.readthedocs.io/en/latest/) to deploy and intergate the lambda function and the API gateway endpoint. Autopilot server also masks the access to the EKS control-plane to determine the current demand for game-servers. 

Before deploying the lambda function that powers autopilot server, populate the variable `endpoint_names` that denotes the model inference endpoint in [app.py](app.py). Also populate the `gs_inventory_url` variable with the EKS API Server. 

Deploy the autopilot server by executing:

```bash
cd ap-server/
chalice deploy
``` 
Chalice create a lambda function and a role it assumed upon a call to the server. The role should have `dynamodb:GetItem` and `dynamodb:PutItem` permissions to `table/latest_observations`. 

Test it by invoking the `/predict` method, e.g.,

```bash
[ap-server]$http https://o2p5pgyyk0.execute-api.us-west-2.amazonaws.com/api/predict/us-west-2

                }
            ]
        }
    }
}
```

The next step is to deploy [game-server autopilot client](../ap_client)
