quiet/silent option

[helio-frota]

would be good to have a quiet (-q) or silent (-s) option

e.g:

2017-04-04 11:37:00,094 root         INFO     docker-squash version 1.0.5, Docker 6b644ec, API 1.24...

using the quiet / silent option:
or maybe output nothing. ?

2017-04-04 11:37:10,249 root         INFO     Done

How about just redirecting it to /dev/null? It looks that you are interested in binary output - succeeded or failed.

[helio-frota]

I tried to do this but for some reason it did not work.
I've added to this line (on my local branch) :
https://github.com/bucharest-gold/origin-s2i-nodejs/blob/master/build/build.sh#L40
( I'll check again today )

I'm interested on CI logs cleanup because we are make builds inside a for loop of several images.

[goldmann]

Look at #144. You need to redirect stderr too: docker-squash... &>/dev/null.

@goldmann Thanks !
I'm going to close this issue.
