You can create your own Docker image as follows.

FROM psmiraglia/tomcat8:8.5.13

# become root
USER root

# set timezone
RUN apk add --no-cache --update tzdata && rm -fr /var/cache/apk/*
ENV TZ=Europe/Rome

# configure and deploy myapp
COPY files/server.xml ${TOMCAT_HOME}/conf/server.xml
COPY files/setenv.sh ${TOMCAT_HOME}/bin/setenv.sh
COPY files/sample.war ${TOMCAT_HOME}/webapps/

# update ownership
RUN chown -R ${TOMCAT_USER}:${TOMCAT_GROUP} ${TOMCAT_HOME}
