#Working with playbooks and enhancing the same.

These playbooks shall be run inside the docker container but you can also run these on host os.

##Building test environmnet to run this playbook.

• Log on to any linux server with docker installed and running.Pull below mentioned docker image.
  

docker pull thinkingmonster/centos7-ansible

• This docker image is already having git and ansible installed to it.Once image is pulled start container using the same.
  

docker run -t -p 8085:8080 -i thinkingmonster/centos7-ansible  /bin/bash

• once you get inside the container create a directory where you can pull these playbooks from github.
  

mkdir /playbooks

• Get into the /playbooks directory and initialize the same.
  

git init

• Pull these playbooks from the github
  

git pull https://github.com/thinkingmonster/ansible.git

• Get inside any playbook. In this example we i will explaining with jenkins playbook
  

cd jenkins-playbook

![Get_inside_container]

• Run below command to run the playbook
  

ansible-playbook jenkins.yml

• Once you execute the above command,notice that playbook will do following.

• Install java.
  

• Install jenkins.
  

• Install require plugings in the jenkins.
  

• stop and start the jenkins.
  

• Once Playbook run is done you can access the jenkins by accessing following url in your browser.
  

http://<host machine>:8085

• Once you exit the container jenkins will also stop.To attach back to the container and continue your testing run below command to get your container id.
  

docker ps -a

• Note down your container id and start the same.
  

docker start <containerid>

• Once container is started.Get attached to the container.
  

docker attach <containerid>

![Attach_container]

Now you are back in your container and can start your testing inside container.Where you exited the container,you will find it in the same stage.With all files intact.You can do a git fetch and can test your changes related to jenkins playbook again.
