The DockerComposeContainer object is created by passing the compose-scaling.yml file. The DockerComposeContainer object is configured to scale the s1 and s2 services to 2 and 3 respectively. The exposed ports of the s1 and s2 services are configured to wait for HTTP status code 200. The DockerComposeContainer object is then started by calling the start() method
