#### [ Amazon CLI ]

1. Run `describe-service-deployments` to retrieve the service revision ARN. 

   Replace the variables with your values.

   ```
   aws ecs describe-service-deployments --service-deployment-arns arn:aws:ecs:{{region}}{{:account-id}}:service/{{cluster-name}}/{{service-name}}/{{NCWGC2ZR-taawPAYrIaU5}}
   ```

   Note the `arn` for the `sourceServiceRevisions` or the `targetServiceRevisions`.

   ```
   {
       "serviceDeployments": [
           {
               "serviceDeploymentArn": "arn:aws:ecs:us-west-2:123456789012:service-deployment/example/sd-example/NCWGC2ZR-taawPAYrIaU5",
               "serviceArn": "arn:aws:ecs:us-west-2:123456789012:service/example/sd-example",

                   "deploymentCircuitBreaker": {
                       "enable": false,
                       "rollback": false
                   },
                   "maximumPercent": 200,

           }
       ],
