Ansible 2.9 -> core

[rrbanda]

Have an agent that can help upgrade ansible playbooks from Ansible 2.9 -> core

[jopaik]

The following has 3 examples of ansible playbook to install webserver from Gemini.
Generally fqcn is a big difference after ansible-core version 2.9 and starting 2.10 fqcn is used to name all modules although it still supports some old style of naming convention. Each version will also have deprecated modules and plugin that has a corresponding newly supported module/plugin names.

**** example of playbook that gemini provided to install webserver on rhel : This seems to be using the latest version***

• name: Install Web Server on RHEL
  hosts: webservers # This refers to a group named 'webservers' in your Ansible inventory
  become: yes # This ensures the playbook runs with elevated privileges (sudo)

  vars:

  Define the web server package name. 'nginx' is available on RHEL via EPEL.

  If you prefer Apache on RHEL, change this to 'httpd'.

  web_server_package: nginx

  tasks:

  • name: Ensure EPEL repository is installed (for Nginx on RHEL/CentOS)
    ansible.builtin.yum: # Using FQCN for yum module
    name: epel-release
    state: present
    when: ansible_os_family == "RedHat" and web_server_package == "nginx"

    This task is specific to RHEL-based systems and only runs if Nginx is chosen.

  • name: Install the chosen web server package
    ansible.builtin.package: # Using FQCN for package module
    name: "{{ web_server_package }}"
    state: present # Ensures the package is installed

    This task will install 'nginx' or 'httpd' based on your 'web_server_package' variable.

  • name: Ensure the web server service is running and enabled at boot
    ansible.builtin.service: # Using FQCN for service module
    name: "{{ web_server_package }}"
    state: started # Ensures the service is currently running
    enabled: yes # Ensures the service starts automatically on boot

  • name: Open HTTP port in firewall (if firewalld is active)
    ansible.posix.firewalld: # Using FQCN for firewalld module (requires python-firewalld on target)
    service: http
    permanent: yes
    state: enabled
    when: ansible_os_family == "RedHat" and ansible_facts.services['firewalld.service'] is defined and ansible_facts.services['firewalld.service'].state == 'running'

    This task ensures the HTTP port is open in the firewall for web access.

    It's conditional to run only on RHEL and if firewalld service is detected and running.

***** Example of Ansible playbook using 2.9 and below *****

• name: Install Web Server on RHEL
  hosts: webservers # This refers to a group named 'webservers' in your Ansible inventory
  become: yes # This ensures the playbook runs with elevated privileges (sudo)

  vars:

  Define the web server package name. 'nginx' is available on RHEL via EPEL.

  If you prefer Apache on RHEL, change this to 'httpd'.

  web_server_package: nginx

  tasks:

  • name: Ensure EPEL repository is installed (for Nginx on RHEL/CentOS)
    yum: # Module name without FQCN for Ansible 2.9
    name: epel-release
    state: present
    when: ansible_os_family == "RedHat" and web_server_package == "nginx"

    This task is specific to RHEL-based systems and only runs if Nginx is chosen.

  • name: Install the chosen web server package
    package: # Module name without FQCN for Ansible 2.9
    name: "{{ web_server_package }}"
    state: present # Ensures the package is installed

    This task will install 'nginx' or 'httpd' based on your 'web_server_package' variable.

  • name: Ensure the web server service is running and enabled at boot
    service: # Module name without FQCN for Ansible 2.9
    name: "{{ web_server_package }}"
    state: started # Ensures the service is currently running
    enabled: yes # Ensures the service starts automatically on boot

  • name: Open HTTP port in firewall (if firewalld is active)
    firewalld: # Module name without FQCN for Ansible 2.9
    service: http
    permanent: yes
    state: enabled
    when: ansible_os_family == "RedHat" and ansible_facts.services['firewalld.service'] is defined and ansible_facts.services['firewalld.service'].state == 'running'

    This task ensures the HTTP port is open in the firewall for web access.

    It's conditional to run only on RHEL and if firewalld service is detected and running.
