Description
When running as non-root, I'm getting the following error in the log:
Unable to create directory for deployment: [/usr/local/tomcat/conf/Catalina/localhost]
As this directory is not part of the Tomcat distribution, tomcat tries to create it itself, but if you're running as non-root, Tomcat won't have the privileges to do so.
No Linux guru myself I wonder if this fixable in the dockerfiles provided here, as it seems to entail giving write/execute permissions to all parent folders for the user used to run Tomcat and allowing that user modification access to the /conf folder looks to me to be not so desirable
Also not sure how dynamic those folder names (Catelina and localhost) are

Research direction
Review the repository's Dockerfiles and the non-root runtime setup, then trace creation of /usr/local/tomcat/conf/Catalina/localhost. Confirm which directory permissions cause the logged failure and determine a narrowly scoped way for deployment directory creation to succeed without broadly making /conf writable; done means the image runs as non-root without this error.
