how to deploy war file in tomcat 7 of docker container

I don't know how to deploying the war file into tomcat 7 with the help of docker container.

It is easy in windows OS because we manually paste our project's war file into webapps folder of tomcat, but in case of docker container it is little bit difficult.

I don't know how to change port of tomcat and add role manager in tomcat-users.xml file in docker because of directory structure of docker container. and how to start tomcat using newly change port number in docker.

As for March 2021, using a single command line solution on a Windows Docker, try this:

docker run --name YourApp -v "c/WarFiles/YourApp.war:/usr/local/tomcat/webapps/YourApp.war" -it -p 9090:8080 tomcat:7

Then open your app at http://localhost:9090/YourApp

Note "double quote" in volume and c drive with "Linux" slash / in order to make it work.

The easiest way is to use the volume parameter (-v) with docker run to have the webapps directory and tomcat-users.xml file stay on the host filesystem, not on the container one.

For instance, on a Linux host:

  • create a file named /tmp/tomcat-users.xml with the correct content for your needs;
  • Then, create an empty directory named /tmp/webapps.

Now, run your container this way:

docker run -it --rm -p 8888:8080 -v /tmp/tomcat-users.xml:/usr/local/tomcat/conf/tomcat-users.xml:ro -v /tmp/webapps:/usr/local/tomcat/webapps:rw tomcat:7

Then, since the container is started in foreground, connect to another shell (another window) and copy your war file into /tmp/webapps. It will be automatically deployed.

For instance, on a Windows host:

  • create a file named c:\tmp\tomcat-users.xml with the correct content for your needs;
  • Then, create an empty directory named c:\tmp\webapps.

Now, run your container this way:

docker run -it --rm -p 8888:8080 -v //c/tmp/tomcat-users.xml:/usr/local/tomcat/conf/tomcat-users.xml:ro -v //c/tmp/webapps:/usr/local/tomcat/webapps:rw tomcat:7

Then copy your war file into c:\tmp\webapps. It will be automatically deployed.
