[edit] Playbook Examples
[edit] 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
[edit] 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
[edit] Linux - Set the permissions for all files and folders within a directory recursively
This uses the file module. It should be noted that while it will set the execution bit on directories (if there is none), it will not do so on files UNLESS at least (1) execution bit is already set.
$ cat /etc/ansible/playbooks/ansible_permissions.yml
- hosts: ansible
tasks:
- name: ansible permissions
file:
#state: directory
path: /etc/ansible
owner: root
group: root
mode: u=rwX,g=rX,o=rX
recurse: yes
