Dockerfile with Tomcat catalina.sh run does not run

Question

I can build the Dockerfile. When I do docker run -it path-to-image/tomcat9:latest and check the logs, there isn't a catalina.out and the run fail with getting /bin/sh: ["catalina.sh",: command not found.

Here is my Dockerfile

FROM gitlab-registry.gs.mil/gets-development/docker/openjdk11

USER root

# Copy Tomcat and start
ADD imageFiles/apache-tomcat-9.0.65.tar.gz /usr/local/
RUN mv /usr/local/apache-tomcat-9.0.65/ /usr/local/tomcat

ENV WORKPATH /usr/local
WORKDIR $WORKPATH

ENV CATALINA_HOME /usr/local/tomcat
ENV CATALINA_BASE /usr/local/tomcat

ENV PATH $PATH:$CATALINA_HOME/bin:$CATALINA_HOME/lib

EXPOSE 8080
CMD ["/usr/local/tomcat/bin/catalina.sh", "run"]

Build command:

docker build -t gitlab-registry.gs.mil/gets-development/docker/tomcat9-test .

Start command:

docker run --name tomcatTest -it gitlab-registry.gs.mil/gets-development/docker/tomcat9-test:latest /bin/bash

Trying to connect inside the docker container to the localhost fails

curl: (7) Failed to connect to localhost port 8080: Connection refused

There are no log files

[root@b058163e9605 local]# cd tomcat/logs/
[root@b058163e9605 logs]# ls -als
total 0
0 drwxr-x--- 2 root root   6 Jul 14 12:28 .
0 drwxr-xr-x 9 root root 220 Aug  5 16:17 ..
[root@b058163e9605 logs]# 

This is telling me that Tomcat did not start. Starting Tomcat inside the container, tomcat could launch success:

Last, I check the Docker logs shows me what I did inside the container, but no other information.

Please assist.

Your docker run command does not launch Tomcat but simply bash. Notice the last argument

docker run --name tomcatTest -it gitlab-registry.gs.mil/gets-development/docker/tomcat9-test:latest /bin/bash

change it into

docker run --name tomcatTest gitlab-registry.gs.mil/gets-development/docker/tomcat9-test:latest

If you want a shell to investigate what is going on inside a running container, use

docker exec -it tomcatTest /bin/bash
