Java Servlet Demo for Jenkins CI

Sample Java Web Application with Servlet API 3.x

lokeshsingana

This demo is based on servlet demo from oracle sample available here.

I have made few fixes to original demo to make it compatible with current scenario.

I have modified my Dockerfile to support Multi Stage Build.

You just need docker installed to build entire webapp and also create an executable container image for it.

Steps

1. Use either cmd or powershell or bash terminal and use following commands:

   NOTE: the $ symbol represent a prompt it's not part of command.

   ## clone this repository in current directory
   ## Don't worry, You DON'T NEED GitHub account!
   $ git clone https://github.com/mahendra-shinde/ci-servlet-demo
   $ cd ci-servlet-demo
   ## Build a new container image `temp` (can be replaced with whatever name you want!)
   $ docker build -t temp .
   

2. Once you build an image, run the application using following command:

   ## replace `temp` with image name you have used in last command
   $ docker run --name myapp -d -p 8080:8080 temp

3. Now, Open web browser to visit url http://localhost:8080/

4. Now, to clean-up, stop the above container and delete it.

   ## stop and delete the container
   $ docker stop myapp
   $ docker rm myapp
   ## Optionally, delete the image as well
   ## WARN: image cannot be deleted if any stopped / running container
   ## is based on this image.
   $ docker rmi temp
