Major Version Upgrade : Using Ansible template instead of old bash script based installation of k8s on linux nodes

Why Ansible?

Ansible offers several advantages over traditional Bash scripting for configuration management and automation tasks:  

1. Declarative approach:

Ansible uses a declarative approach, where you describe the desired state of your systems. This makes your scripts more readable, maintainable, and easier to understand.  
Bash scripts, on the other hand, are imperative, requiring you to specify the exact steps to achieve the desired state.  
2. Idempotency:

Ansible is idempotent, meaning it can be safely run multiple times without causing unintended changes. If a configuration is already in the desired state, Ansible will do nothing.  
Bash scripts, unless carefully designed, may not be idempotent, leading to inconsistent results.
3. Modularity:

Ansible is built around the concept of modules, which encapsulate specific tasks. This promotes reusability and makes it easier to manage complex configurations.  
Bash scripts often require more manual effort to break down tasks into smaller, reusable components.
4. Inventory management:

Ansible provides a powerful inventory system for managing groups of hosts. This makes it easy to target specific systems or groups for configuration changes.  
Bash scripts typically require manual management of host lists.
5. Role-based configuration:

Ansible allows you to organize tasks into roles, which can be reused across different playbooks. This promotes modularity and reusability.  
Bash scripts often lack built-in support for roles and modularization.
6. Built-in features:

Ansible includes many built-in features and modules for common configuration tasks, such as managing packages, services, and files.  
Bash scripts may require you to write custom code for these tasks.
7. Community and ecosystem:

Ansible has a large and active community with extensive documentation, tutorials, and modules available.  
This makes it easier to learn and use Ansible effectively.
While Bash scripting can be useful for simple tasks, Ansible offers a more robust and efficient solution for complex configuration management and automation needs. By leveraging Ansible's declarative approach, idempotency, modularity, and other features, you can streamline your workflows and improve the reliability of your infrastructure.
