✿ What is Ansible ?

Ansible is an open-source automation tool, or platform, used for IT tasks such as configuration management, application deployment, intraservice orchestration, and provisioning.

✿ What is Roles in Ansible ?

Ansible Roles provide a framework for fully independent, or interdependent collections of variables, tasks, files, templates, and modules. In Ansible, the role is the primary mechanism for breaking a playbook into multiple files. This simplifies writing complex playbooks, and it makes them easier to reuse.

🔰 So let’s begin….

♦️ Inventory File :

♦️ Ansible Configuration File :

🔅 Create an ansible role “webserver” to configure httpd WebServer.

ansible-galaxy role init webserver

🔅 Create another ansible role “mylb” to configure HAProxy LB.

ansible-galaxy role init mylb

♦️ Here, you can see two roles created :

ansible-galaxy role list

Now writing roles :

♦️ In webserver role,

a) In tasks ;

b) In vars ;

c) In template;

♦️ In mylb role,

a) In tasks ;

b) In vars ;

c) In templates ;

🔅 We need to combine both of these roles controlling webserver versions and solving challenge for host ip’s addition dynamically over each Managed Node in HAProxy.cfg file.

♦️ In main playbook setup.yml ,

♦️ Now running the playbook

♦️ Now to check on browser :

Finally our Task is completed successfully !!!!😄✌🏻
