Substitute docker version:

curl -s \
  --unix-socket /var/run/docker.sock \
  http://localhost/version

If curl is missing:

docker run --rm \
  --volume /var/run/docker.sock:/var/run/docker.sock \
  nathanleclaire/curl \
  curl -s \
    --unix-socket /var/run/docker.sock \
    http://localhost/version
