- Create tasks.
- Create service.
- Zero downtime deploy.
- Create monitoring using CloudWatch.
- Receive an json with containers definitions.

}
}
]- The
nameof one container created oncontainers_definitions.jsonshould be the same asapp_namepassed to module. - You can configure almost everything as variable, and you probably should do this.
