I use docker to deploy a Java web application in tomcat. For testing purposes, I want to force the system date to a specific value.
With Docker it is not possible to change the container date without affecting the host date. So I would like to use Faketime. This tool allows to manipulate the system date for a given command. For example :
$ date Web Jul 1 09:57:51 UTC 2015 $ faketime "2008-12-24" date Web Dec 24 00:00:00 UTC 2008
Howewer when I use it starting tomcat, I got a sem_open error :
$ faketime "2008-12-24" /bin/bash -c "/opt/tomcat/bin/catalina.sh start" [...] Tomcat started. $ tail -f /opt/tomcat/logs/catalina.out sem_open: No such file or directory
Any idea to resolve this problem?
