Works since docker-compose version 1.25.1
Requires docker to be present
Set COMPOSE_DOCKER_CLI_BUILD=1 to use docker for builds
Set DOCKER_BUILDKIT=1 to enable BuildKit
Enable building using CLI:
export COMPOSE_DOCKER_CLI_BUILD=1
Enable BuildKit:
export DOCKER_BUILDKIT=1
Build using docker-compose:
docker-compose build
