As you know Jenkins has over 1700 plugins available which make him one of the most powerful and flexible tool ever created:) so let’s see one of the most interesting plugin:Making builds with Ansible Plugin.
What is Ansible?
It is a tool to deploy software and application on many servers, it can be really useful in case of update patch or new versions to be added on many machines , with Ansible all that can be done in a row 😀
You can find on dbi bloggers some interesting topics on Ansible, I invite you to take a look on it!
Install Ansible on your Jenkins Master[[email protected] ~]# yum install Ansible

That’s it , you know now how to invoke an Ansible playbook using Jenkins, note that you have many ways to do that,this time we saw by using Ansible plugin , but you can also put the playbook command in a pipeline or store your playbooks directly on you git.
Next time we will see how to troubleshoot some issues encountered for this demo and some other tricks on Jenkins 😉 ,stay tuned
