+### How can I iterate ECS modification testing
+
+After applying your modifications (vía terraform for example) restart the service
+  ```
+  $ aws ecs update-service --force-new-deployment --cluster sysdig-secure-for-cloud-ecscluster --service sysdig-secure-for-cloud-cloudconnector --profile <AWS_PROFILE>
+  ```
+For the AWS_PROFILE, set your `~/.aws/config` to impersonate
+  ```
+  [profile secure-for-cloud]
+  region=eu-central-1
+  role_arn=arn:aws:iam::<AWS_MANAGEMENT_ORGANIZATION_ACCOUNT>:role/OrganizationAccountAccessRole
+  source_profile=<AWS_MANAGEMENT_ACCOUNT_PROFILE>
+  ```
