In an era of IT environments, automation is no longer a luxury—it's a necessity. Ansible, an open-source IT automation tool, has become a go-to solution for streamlining IT tasks. This comprehensive course aims to equip you with both fundamental and advanced Ansible knowledge.

You'll start by installing Ansible, understanding its architecture, and diving into inventory management and playbook creation. Next, you'll explore variables, conditional statements, loops, handlers, roles, and collections. After that, the course dives into Ansible for Linux-specific tasks and troubleshooting techniques to resolve common problems like connection failures, missing parameters, and syntax errors. 

After completing this course, you'll have gained a robust understanding of Ansible, with the ability to create efficient playbooks, manage inventory, troubleshoot common problems, and automate a wide range of IT tasks. These skills will provide a strong foundation for a thriving career in IT infrastructure management.

Automating IT Infrastructure with Ansible

Loop statements automate repetitive tasks in our Ansible playbook.
Computers are better at repeating identical or similar tasks without errors than humans.
The repeated execution of a set of statements is called **iteration**.

## Iteration statements in Ansible

Ansible has several statements for iteration. We will focus on the following two statements:

- The `loop` statement
- The `with_items` statement

## The `loop` statement

A simple loop iterates a task over a list of items. The `loop` statement is added to the task and takes the list of items over which the task should be iterated as a value.


---
- name: Check services
  hosts: all
  tasks:
  - name: httpd and sshd are running
    ansible.builtin.service:
      name: "{{ item }}"
      state: started
    loop:
      - apache2
      - sshd

In our playbook, we used the `item` variable that will be substituted in Ansible runtime with the current value during each iteration of the loop.

We can execute the Ansible playbook using the `ansible-playbook` command-line utility.
The full command is as follows:

```
ansible-playbook -i inventory loop_simple.yml
```

It produces the following output:
