What are some examples of Ansible playbooks?

Can you provide some examples of Ansible playbooks?

Sure! Ansible playbooks are YAML files that define a series of tasks to be executed on remote machines. Here are a few examples:

1. Basic Web Server Setup: This playbook installs Apache and starts the service.

   - hosts: webservers
     tasks:
       - name: Install Apache
         yum:
           name: httpd
           state: present
       - name: Start Apache
         service:
           name: httpd
           state: started
   

2. User Management: This playbook creates a new user and sets up SSH access.

   - hosts: all
     tasks:
       - name: Create a new user
         user:
           name: johndoe
           state: present
           shell: /bin/bash
       - name: Add SSH key
         authorized_key:
           user: johndoe
           state: present
           key: "ssh-rsa AAA..."

Yes, can you show me a playbook for deploying a Docker container?

Absolutely! Here’s a simple playbook for deploying a Docker container:

- hosts: docker_hosts
  tasks:
    - name: Install Docker
      apt:
        name: docker.io
        state: present

    - name: Pull Docker image
      docker_image:
        name: nginx
        tag: latest
        source: pull

    - name: Run Docker container
      docker_container:
        name: my_nginx
        image: nginx:latest
        state: started
        ports:
          - "80:80"

This playbook installs Docker, pulls the Nginx image, and runs it as a container. Would you like to know more about Docker or Ansible?

That sounds great! Can you explain how to use variables in Ansible playbooks?

Sure! Variables in Ansible playbooks allow you to store values that can be reused throughout your playbook. Here’s an example:

- hosts: all
  vars:
    http_port: 80
    max_clients: 200
  tasks:
    - name: Install Apache
      yum:
        name: httpd
        state: present

    - name: Configure Apache
      template:
        src: /path/to/httpd.conf.j2
        dest: /etc/httpd/conf/httpd.conf
      notify:
        - restart apache

  handlers:
    - name: restart apache
      service:
        name: httpd
        state: restarted

In this example, http_port and max_clients are variables that can be used in your tasks or templates. Would you like to dive deeper into templates or handlers?
