Tasks

Check ansible version.

ansible --version

Check if you’re able to ping localhost

ansible localhost –m ping

Task 1

Create a file named task1.yml and copy past content in blue into the same file.

---
- hosts: localhost
  become: yes
  tasks:
  - name: create a directory using shell

    shell: ls -l
    register: result
  - debug: var=result

  - name: Install tree
    apt: name=tree state=latest

Command to execute

ansible-playbook task1.yml

Verification: You can find both directories named “test_dir1” and “test_dir2”

ls –l /var/log

Task 2

Create a file named task2.yml and copy past content in blue into the same file.

---
- name: Task-02
  hosts: localhost
  gather_facts: yes
