You can use the withCommand() method to pass the docker-compose.yml file to the Docker Compose executable. The following code shows how to do it:9new DockerComposeContainer(new File("docker-compose.yml"))10    .withExposedService("redis_1", 6379)11    .withCommand("up")12    .start();13new DockerComposeContainer(new File("docker-compose.yml"))14    .withExposedService("redis_1", 6379)15    .withLocalCompose(true)16    .withFileFromFile("docker-compose.yml", new File("docker-compose.yml"))17    .start();18In the above code, we have used the withFileFromFile() method to add the docker-compose.yml file to the DockerComposeContainer class. The withFileFromFile() method takes two parameters. The first parameter is the name of the file that you want to add to
