**To deregister a gateway instance**

1. Open the MediaConnect console at [https://console.aws.amazon.com/mediaconnect/](https://console.aws.amazon.com/mediaconnect/).

1. From the navigation pane, select **Gateways**. In the **Gateways** section, select the gateway that contains the instance you want to deregister. 

1. On the gateway **Details** page, select the **Instances** tab. Select the **Instance ID** of the instance you want to deregister.

1. Select **Deregister**.

1. Confirm the deregistration of the instance by selecting **Deregister instance**.

### Reusing a gateway instance


If you want to reuse the instance for Amazon ECS Anywhere or as another gateway instance, you will need to complete the following steps.

**To reuse a gateway instance (optional)**

1. Open the MediaConnect console at [https://console.aws.amazon.com/mediaconnect/](https://console.aws.amazon.com/mediaconnect/).

1. From the navigation pane, select **Gateways**. In the **Gateways** section, select the gateway that contains the instance you want to reuse. 

1. On the gateway **Details** page, select the **Instances** tab. Locate the **Instance ID** of the instance you want to reuse.

1. Make sure that the **Instance state** is **Deregistered** for the instance you want to reuse.

1. From a computer with the access to do so, connect to the instance using SSH.

1. Run the following commands, in order.

   ```
   sudo docker stop $(sudo docker ps -f "name=MediaConnectGatewayAgent" -q); \
   sudo docker stop ecs-agent; \
   sudo systemctl stop ecs amazon-ssm-agent; \
   sudo yum remove -y amazon-ecs-init amazon-ssm-agent;  `# or apt or snap as needed` \
   sudo rm /var/lib/ecs /etc/ecs /var/lib/amazon/ssm /var/log/ecs /var/log/amazon/ssm -rf; \
   sudo docker rm -f ecs-agent ssm-agent; \
   sudo docker container rm -f $(sudo docker ps -a -f "name=MediaConnectGatewayAgent" -q); \
   sudo docker volume rm -f ecsdata docker run; \
   sudo pkill -f -KILL network_bootstra[p]; \
   sudo pkill -KILL mcproxy;
   ```
