Docker Tomcat Application Logs(logback.xml) not coming

  1. When I installed application on tomcat8.5 its log were not coming
    common logs were coming but application logs were not coming

manager.2018-11-29.log
host-manager.2018-11-29.log
localhost_access_log.2018-11-29.txt
app.log
localhost.2018-11-29.log
catalina.2018-11-29.log

This app.log file is not being generated, but when we run this application outside docker then it is working properly
