Docker image not running with https and tomcat

I am trying to run docker image with https URL instead of just http. The app is deployed in tomcat and I have generated docker image of it. When I run tomcat on https URL, it works fine but when I build docker image and try to run the image, the URL is not working.

Dockerfile

FROM tomcat:9.0.35

COPY conf/my-release-key.keystore /usr/local/tomcat/conf/my-release-key.keystore
COPY conf/server.xml /usr/local/tomcat/conf/server.xml
ADD webapps/placeholder-webapp.war /usr/local/tomcat/webapps/

EXPOSE 8080 8445
CMD ["catalina.sh","run"]

server.xml

<Connector port="8445" protocol="org.apache.coyote.http11.Http11NioProtocol" maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
           keystoreFile="conf/my-release-key.keystore" keystorePass="arcsight"
           clientAuth="false" sslEnabledProtocols="TLSv1.2,TLSv1.3" sslProtocol="TLS">
    </Connector>
    <!-- Define an AJP 1.3 Connector on port 8009 -->
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8445" />

Output on running docker image: enter image description here

I don't get any error on running docker image but I don't even see anything on accessing

The ports you are using, 8445 and 8009 should be opened with EXPOSE in your Dockerfile.

Can you enable SSL in server.xml by adding the following code and then copy it in the container COPY server.xml /usr/local/tomcat/conf/

<!--
  <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="150" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" />
-->

And apart from this EXPOSE 8443, in the Dockerfile instead of EXPOSE 8080, and then hit your service on https://localhost:8443

You need to expose port 8445 in Dockerfile using EXPOSE 8445 and run the container using -p 8445:8445 to map local port 8445 to port 8445 running inside the container.

Your logs don't show that tomcat is aware that it needs to prepare a connector to run on port 8445. It must be using default server.xml configuration. You need to provide your server.xml to the container using something like following.

COPY server.xml /usr/local/tomcat/conf/
