dockerfile to deploy to tomcat server does not display webapp

Question

I am using Jenkins to deploy a maven hello-world file to a docker tomcat image. the mvn clean package command works well in the jenkins job, and the subsequent dockerfile spawns an image where the webapp.war file will be placed in tomcat home directory.(/usr/local/tomcat/webapp/webapp.war) This is supposed to display o/p on the tomcat page running over port 8181, but i cannot get it to work. The tomcat is working though

The Repo which contains the Jenkinsfile and Dockerfile is https://github.com/Kush-2806/Maven-Docker-CI

This is the output instead of the hello world

You have an error in your Dockerfile .

The directory is called /usr/local/tomcat/webapps/ , so you are just one s short - in your Dockerfile you copy to this location /usr/local/tomcat/webapp/

Update the Dockerfile to this:

FROM tomcat:8.0

ADD ./webapp/target/*.war /usr/local/tomcat/webapps/

EXPOSE 8080

CMD ["catalina.sh", "run"]

Now visit the site http://localhost:8181/webapp
