Ansible Zero to Hero — Import Playbook Execution on the Remote Machines Using Terraform & Ansible— Part 2

ansible-playbook is a command-line tool in Ansible, an open-source automation tool used for configuration management, application deployment, task automation, and managing IT infrastructure. Ansible uses a declarative language to describe the desired state of the system, and ansible-playbook is used to execute a collection of tasks defined in a playbook.

Inventory: Ansible uses an inventory file to define the hosts on which it should run tasks. This file typically contains information such as hostnames or IP addresses, connection details, and groupings of hosts.

Example inventory.ini file:

[webserver]
4.193.143.97
[dbserver]
4.194.182.229

---
- name: Example Playbook
  hosts: webserver
  become: yes

  tasks:
    - name: Ensure Nginx is installed
      apt:
        name: nginx
        state: present

    - name: Ensure Nginx is running
      service:
        name: nginx
        state: started

Running the Playbook: To execute a playbook, you use the ansible-playbook command followed by the name of the playbook file:

ansible-playbook -i inventory.ini playbook.yml

Same execution we can perform using terraform local-exec

 provisioner "local-exec" {
    command = "ansible-playbook './ansible-nginx.yaml' -u adminuser"
  }

Result :

The import_playbook directive in Ansible is used to include another playbook, similar to include_playbook. However, there is a key difference: import_playbook is a static import, and it includes the specified playbook at the same level as the tasks in the calling playbook

• The import_playbook directive is used to import playbook1.yml and playbook2.yml.
• The tasks in the main playbook will be executed before and after the imported playbooks.
• import_playbook is more suited for cases where you want to control the order of execution of the playbooks.
