## 500-generate-tomcat-catalina-base.sh
##
## Automcatically generates a fresh, temporary CATALINA_BASE for Apache Tomcat.
## This allows Tomcat to run as a reduced-privilege user, and allows its
## configuration to be dynamically generated by the container entrypoint at
## startup.
##

# Start with a fresh CATALINA_BASE
#

rm -rf /tmp/catalina-base.*
export CATALINA_BASE="`mktemp -p /tmp -d catalina-base.XXXXXXXXXX`"

# User-only writable CATALINA_BASE
for dir in logs temp webapps work; do
    mkdir -p $CATALINA_BASE/$dir
done
cp -R /usr/local/tomcat/conf $CATALINA_BASE
