Creating a Tomcat container

In this section, we will create a container with the Tomcat web server installed so that we can deploy Java-based web applications into it:

1. Create an account in Docker hub and Login:

2. We can search different images from the Docker hub:

3. You can find the Tomcat image at https://hub.docker.com/_/tomcat/. 
4. Use Docker's pull command to get the Tomcat image:

        docker pull tomcat 

5. Once the Tomcat image is available, verify it using the docker images command:

6. To run docker container from the image, run docker run -it --rm -p 8888:8080 tomcat:8.0.

7. Use the IP address of the default docker machine and port 8888 in the browser to verify whether Tomcat is running properly in the container or not:

8. To get the IP address of the virtual machine, execute docker-machine ls command.

Let's verify whether we have access to the Tomcat manager application in this container: 

What we will do here is, create a new image with our own tomcat-users.xml, where we will create a user with the manager...
