Change log settings

What is the best way to change the debug log settings at a docker container? I changed all the attributes in the log4js_configuration.json files at /nuve, /erizo:controller and /spine to log level “ERROR”, then restarted the docker container but nothing changed. Still get massive amount of “INFO” logs like:

INFO [0x7fc502ffd700] StreamStats - {"SL0TL0":0,"SL0TL1":0,"SL0TL2":0,"SL0TL3":0,"SL1TL0":0,"SL1TL1":0,"SL1TL2":0,"SL1TL3":0,"SL2TL0":0,"SL2TL1":0,"SL2TL2":0,"SL2TL3":0,"SL3TL0":0,"SL3TL1":0,"SL3TL2":0,"SL3TL3":0,"audioBitrate":21860,"audioEnabled":1,"audioFL":0,"audioJitter":459,"audioMuted":0,"audioNack":0,"audioPL":0,"audioRemb":0,"bwe":0,"isPublisher":0,"maxActiveSL":0,"maxActiveTL":0,"maxVideoBW":300000,"paddingBitrate":0,"qualityCappedByConstraints":0,"rtxBitrate":0,"selectedSL":0,"selectedTL":0,"slideshow":0,"streamId":"eb45dab4-a342-413e-bcc8-cdde88672fc1_153873807759244100","totalBitrate":21860,"videoBitrate":0,"videoEnabled":1,"videoErizoRemb":0,"videoFL":0,"videoFir":0,"videoJitter":0,"videoKeyFrames":0,"videoMuted":0,"videoNack":0,"videoPL":0,"videoPli":0,"videoRemb":0}
