Welcome to the DevOps test repository for Maven projects

************************************************************

To use this, your system (Centos 7) should have below tools installed:
git  //you can use "yum install git -y" for this
maven  //you can use "yum install maven -y" for this
jenkins //follow the installation guideline at https://www.jenkins.io/doc/book/installing/#red-hat-centos

 sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin
 
 systemctl start docker

use maven to clean the previous builds and  package the war file 
mvn clean
mvn package

check the outputs in target directory structure and war file with name devops.war

build the docker image with docker build command ( you can see dockerfile in present working directory)
docker build -t image-name:version .

docker rm -f `docker ps -aq`

Run a container from the image
docker run -d -p 8081:8080 --name mynewcontainer image-name:version    {8080 port is taken by jenkins}
