Installing Tomcat 8.* in a docker container with Centos 7

Question

I want to create a docker container to install Tomcat within it. It seems that my docker compiles with no problem and I am also able to run tomcat with no problems reported through the logs. Yet, if I try to open tomcat I get a 404 error. I do not know what I am missing. Any ideas, please? The next is the content of my Dockerfile:

FROM centos:7

my setenv.sh file content is:

export JAVA_HOME=/opt/javaSDK

export LD_LIBRARY_PATH

Did you ever solve this? Does this installation work on a bare metal machine? I was considering repeating your steps, but if you solved it then I might not need to. — Jerry, Aug 12 '20 at 21:13

The important part is to somehow add the next xommands to the dockerfile:

#---------------------------------------- Donwload and install open apr ------------------------------------------------------------
ENV APRVERSION 1.6.5
RUN wget http://apache.mirrors.ionfish.org//apr/apr-${APRVERSION}.tar.gz
RUN tar -xvf apr-${APRVERSION}.tar.gz
RUN mv apr-${APRVERSION} apr
RUN mv apr /opt/software/apr
RUN cd /opt/software/apr/ && \
    ./configure --prefix=/opt/software/ && \
     make && make install

#------------------------------------------ Copy TOMCAT native


# compiling tomcat native

RUN cd ${CATALINA_HOME}/bin/ && \
    tar -xvf tomcat-native.tar.gz && \
    cd tomcat-native-1.2.8-src/native/ && \
     ./configure --with-apr=/opt/software/ --with-java-home=/opt/javaSDK/ --with-ssl=/opt/software  --prefix=/opt/tomcat && \
    make && \
    make install

ADD setenv.sh /opt/tomcat/bin/

The tomcat-native.tar.gz must be the one included in the version of Tomcat to be installed which is included in the tomca installation compressed file. Also, the Tomcat applications sample included in the installation file must be at least manually added to the Tomcat's webapps folder. I had problems doing this automatically.
