Image pinning

The pinning suggestions provided in alfresco-base-java are valid for this image too.

Usage

The image can be used via docker run to run java applications with --read-only set.

Depending on your use case, you may want to set the following path as volumes:

/usr/local/tomcat/logs
/usr/local/tomcat/work
/usr/local/tomcat/temp
/usr/local/tomcat/conf/Catalina

The Tomcat in this image is running with Security Manager switched on. This may impact performance. The Security Manager can be disabled by overriding the startup command to:

CMD ["catalina.sh", "run"]
