I am pretty new to Tomcat and Docker – so I am probably missing a Tomcat fundamental somewhere in this question.
What I am trying to do is build a Docker container that runs a SpringBoot Restful web service that just returns some static data. This is all running on OSX so I am using Boot2Docker as well.
I’ve written my own Dockerfile to build the container that my app runs in:
RUN mkdir /usr/local/tomcat/webapps/myapp
COPY /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war /usr/local/tomcat/webapps/myapp/
This Dockerfile works fine and I am able to start the container from the created image.
docker build -t myapp .
docker run -it --rm -p 8888:8080 myapp
This container starts correctly and outputs no errors and displays the message saying my app was deployed.
22-Mar-2015 23:07:21.217 INFO [localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployDirectory
Deploying web application directory /usr/local/tomcat/webapps/myapp
The container also correctly has the myapp.war copied to the path described in the Dockerfile. Moreover I am able to navigate to Tomcat default page to confirm that Tomcat is running, I can also hit all the examples, etc.
To the problem, when I navigate to http://192.168.59.103:8888/myapp/getData I get a 404. I can’t quite figure out why. Am I missing something regarding a .war deploy to Tomcat?
