Set it and forget it

In Ansible playbooks, loops provide flexibility and efficiency to automate Oracle Linux environments or any Linux environment through OLAM. Users can define dictionaries in their playbooks and use loop statements. Dictionaries are like books, with all your infrastructure or applications in lists, and they can be used to describe variables in an automation. This allows a set of tasks to be executed for each item in the loop, reducing the need for repetitive coding and making playbooks more concise and manageable.

For instance, if you want to install multiple packages on a group of Oracle Linux servers without loops, you would need to write separate tasks for each package and server. However, by using loops in OLAM with Ansible, you can define a list of packages and a list of servers and iterate over them, installing the packages on each server in a single task.

Getting ready

In the previous recipe, we’ve shown that OLAM has additional features and...
