Reduce logging file size in docker containers

[sumandari]

Please see #1369

Problem: logging files have big filesize json

e.g:

-rw-r----- 1 root root 1.3G Jan  2 06:08 [#####]/e95bb7b21a91a9aa5db9c6330a8e52b93ca00f13904d31fc261362bcbbf3bbff-json.log
-rw-r----- 1 root root 909M Jan  2 06:08 [#####]/c04d57da8655a21080667e9ddfee5e40775d1d7e3da6a519c9516254118a5343-json.log

Proposed solution: Reduce the container log to avoid running out of disk space.
