When building a docker image from a Dockerfile to run the build in, extreme docker build logging cannot be turned off.
This issue makes the first 20 pages of the build log essentially useless.
Filtering it or adding the -q flag would resolve this.

E.g. from a typical build log with verbose logging flag not enabled:
10:51:06 $ docker build --file /home/esadmin/build/Dockerfile.precise /home/esadmin/build
