Docker not found inside container instead of passed daemon as a volume - docker

Question

Can anybody help me? This docker-compose file worked for me a few days ago with docker command available inside the container, but now it throws: docker: not found inside.
The docker daemon on the host is on /usr/local/bin/docker. It's a mac.
Any idea? Could you help me to try this on yours guys? Thks
