Playbook Examples

CentOS - ensure certain packages are installed

This uses the yum module

~$ sudo cat /etc/ansible/playbooks/centos_base_packages.yml
- hosts: centos
  tasks:
    - name: ensure a list of packages installed
      yum:
        name: "{{ packages }}"
      vars:
        packages:
        - telnet
        - net-tools
        - vim
        - tcpdump
        - bind-utils
        - redhat-lsb-core
        - wget
        - nfs-utils
        - policycoreutils-python
        - setroubleshoot
        - setools

~$  ansible-playbook /etc/ansible/playbooks/centos_base_packages.yml

CentOS - update the hosts file from template

This uses the template module and requires that a template already be created. The template can be a plain host file without variables, will be static, and will replace any existing hosts file in place.

~$ sudo cat /etc/ansible/playbooks/hosts.yml
- hosts: centos
  tasks:
    - name: host file
      template:
        src: /etc/ansible/templates/hosts.j2
        dest: /etc/hosts
