The original fork was made to build the docker image for the Codefresh managed docker-compose image
It was needed for an ARM version of the image, as well as for replacing the --compatibility flag default value from false to true.
Since it was created, the official image started to release ARM versions, as well as exposing the flag as an env variable. However - the official image is not a runnable container. instead, it's just a way to deliver the binaries. so the current Dockerfile just copies the binary for docker-compose into our image and sets the COMPOSE_COMPATIBILITY env variable to true.
