Hello folks, so today we will see that what do you mean by idempotence in Ansible and why restarting HTTPD service through Ansible is not idempotence in nature and how we can rectify it.

What is idempotence ?

Idempotence is the concept that is taken from Mathematics which means that if the current requirement is already present then it won’t be changed. So ansible works on this concept of idempotence i.e let us consider that we have written an ansible playbook to install a particular software in the target node. So ansible before installing the software checks if it is already installed in the…

Pod autoscaling (In kubernetes world we call containers as pods):

OpenShift enables cloud elasticity by providing automatic horizontal pod scaling as application load increases. …


Development Before Jenkins

Before the advent of Jenkins, developers had to complete code testing before they could check for errors. Developers on teams, tending to work independently, each created large segments of code to add to the base code. The entire source code would be checked for errors — a time-consuming and challenging undertaking. Multiple developers would each send commits to version control, increasing the time required to identify and fix bugs. There was no iterative code improvement, and the software delivery process was slow. So for them Jenkins came to the rescue!

What is Jenkins and Continuous Integration?

Jenkins is an open source, cross-platform automation serve that helps…
