ansible-examples

Pros of ansible-for-devops

• More up-to-date and actively maintained
• Comprehensive examples covering modern DevOps practices
• Includes Vagrant configurations for easy testing

Cons of ansible-for-devops

• Less diverse range of examples compared to ansible-examples
• Focused on specific use cases rather than general-purpose examples
• May be overwhelming for absolute beginners

Code Comparison

ansible-examples:

- name: Install Apache
  yum: name=httpd state=present

- name: Start Apache Service
  service: name=httpd state=started enabled=yes

ansible-for-devops:

- name: Install Apache
  apt:
    name: apache2
    state: present

- name: Ensure Apache is running
  systemd:
    name: apache2
    state: started
    enabled: yes

The code snippets show similar tasks but with different syntax and package managers. ansible-for-devops uses more modern Ansible syntax and focuses on Debian-based systems, while ansible-examples uses older syntax and is centered around Red Hat-based systems.

ansible-for-devops provides more detailed examples with explanations, making it easier for DevOps practitioners to understand and implement. However, ansible-examples offers a broader range of scenarios, which can be beneficial for learning various Ansible use cases.

Both repositories serve as valuable resources for learning Ansible, with ansible-for-devops being more suitable for those focusing on modern DevOps practices, and ansible-examples providing a wider array of general-purpose examples.

Pros of workshops

• More comprehensive and structured learning experience
• Regularly updated with new content and examples
• Includes hands-on labs and exercises for practical application

Cons of workshops

• Larger repository size, potentially overwhelming for beginners
• Requires more setup and resources to run workshops
• May contain more complex scenarios than necessary for basic learning

Code Comparison

workshops:

- name: Create Azure VM
  azure_rm_virtualmachine:
    resource_group: myResourceGroup
    name: myVM
    vm_size: Standard_DS1_v2
    admin_username: azureuser
    ssh_public_keys:
      - path: /home/azureuser/.ssh/authorized_keys
        key_data: "{{ ssh_public_key }}"

ansible-examples:

- name: Ensure Apache is installed
  yum:
    name: httpd
    state: present

- name: Ensure Apache is running
  service:
    name: httpd
    state: started
    enabled: yes

The workshops repository provides more advanced examples, such as cloud provisioning, while ansible-examples focuses on simpler, foundational tasks like package management and service control.

Pros of ansible-lint

• Focuses on linting and code quality, helping to identify and fix issues in Ansible playbooks
• Actively maintained with regular updates and improvements
• Integrates well with CI/CD pipelines for automated checks

Cons of ansible-lint

• Limited in scope compared to ansible-examples, which covers a wider range of Ansible use cases
• Steeper learning curve for beginners who may benefit more from practical examples
• May produce false positives or overly strict warnings in some cases

Code Comparison

ansible-lint example:

- name: Install packages
  apt:
    name: "{{ item }}"
    state: present
  loop:
    - nginx
    - postgresql

ansible-examples equivalent:

- name: Install packages
  apt:
    name:
      - nginx
      - postgresql
    state: present

The ansible-lint version uses a loop, which is generally discouraged for simple package installations. The ansible-examples version uses the recommended syntax for multiple package installations.

Pros of AWX

• Provides a web-based user interface for managing Ansible playbooks and inventories
• Offers role-based access control and job scheduling capabilities
• Integrates with various cloud providers and version control systems

Cons of AWX

• More complex setup and maintenance compared to simple example playbooks
• Requires additional system resources to run
• Steeper learning curve for users new to Ansible

Code Comparison

AWX (from awx/main/models/unified_jobs.py):

class UnifiedJob(PolymorphicModel, CommonModelNameNotUnique):
    class Meta:
        app_label = 'main'

    STATUS_CHOICES = [
        ('new', _('New')),
        ('pending', _('Pending')),
        ('waiting', _('Waiting')),
        ('running', _('Running')),
        ('successful', _('Successful')),
        ('failed', _('Failed')),
        ('error', _('Error')),
        ('canceled', _('Canceled')),
    ]

Ansible-examples (from lamp_simple/roles/web/tasks/main.yml):

- name: Install apache and php
  yum: name={{ item }} state=present
  with_items:
   - httpd
   - php
   - php-mysql

The AWX code snippet shows a more complex Python class structure for job management, while the Ansible-examples code is a simple YAML playbook for installing packages.
