Your first docker-compose. Compose takes in a YAML file and creates containers according to its specifications. yml file can only have a few top-level keys, which define "sections" within our configuration file. yml file, it will automatically build the project at the start of the test run, bring the containers up before each test starts, and tear them down after each test ends. For this example, we are only going to be focusing on version, services, and (later on) networks. Is this how you would handle inter-dependencies between compose files? For example, if I had one compose file that includes Transmission and a separate file that includes OpenVPN, and transmission is dependent/linked to OpenVPN, then is this how you get compose to build the containers (running docker-compose against the Transmission compose file on its' own fails as the dependency can't be met)?.
