The service and service-sdk docker containers now log rotates tomcat access logs. By default it removes logs older than three days. A cron job runs daily at 2am UTC. To change the retention, set an environment variable with the desired number of days. For example, to set to 14 days:
docker run --env TOMCAT_LOG_RETENTION_DAYS=14 ...
Docker deployment READMEs were improved (on Docker Hub).
