CMD from Dockerfile fails during daemon run, but can run from interactive shell

I am working on building a container for a very old version of JSPWiki so that we can remove it from an on-prem VM. When I build the image and just run it a daemon mode ( -d ), the application doesn’t start. But, if I run it interactively ( -it … /bin/bash ), I can execute the startup script and it runs as desired.

I’ve tried using --log-level “debug” to see if that would help and I get:

The Dockerfile contains the following:

FROM ubuntu:latest

ENV TOMCAT_VER apache-tomcat-5.5.17
ENV TOMCAT_DIR /usr/local/$TOMCAT_VER
ENV TOMCAT_TAR $TOMCAT_VER.tar.gz
ENV WIKIFILES_DIR /apps/wikifiles

rm -f /tmp/$TOMCAT_TAR

WORKDIR $TOMCAT_DIR

CMD $TOMCAT_DIR/bin/startup.sh

EXPOSE 8080

The above-mentioned errors were viewed by running:

docker --log-level “debug” run -it -v /home/dan/docker/wikipgmr/wikifiles:/apps/wikifiles -p 127.0.0.1:8080:8080 wikipgmr:1.2

The container itself is at dcarrington/wikitest:1.2

I appreciate any help or advice that can be offered.
