Docker Compose 2.0 lost --context flag

There is no --context or -c in Docker Compose 2.0. The following still works on Linux and Mac: DOCKER_CONTEXT=contextname docker-compose up -d

Start with ansible/Makefile at the referenced lines 66 and 70, and inspect how Docker Compose is invoked there. Verify the commands with Docker Compose 2.0 on Linux or macOS, using the documented DOCKER_CONTEXT approach as a comparison. Done means the Makefile commands select the intended context without relying on the missing --context or -c flag.
