Imagine you are having multiple instances and you want to change something, if you will do this manually it will take time from you why not to automte the process ?
I upladed one of the projects to automate the process, this will allow to automate the simplest things for example new employee joined and you need to add his SSH key to your instances (You can even choose which VM you want to him/her to acces) , just add the key in the roles and configure the pipeline on your rep and the code will run Automtically.
I uploaded the project on my github HERE.
