Hi,
I don’t know what you’re trying to achieve exactly … but assuming that all your
vhosts have the same configuration file structure, you could use a template and
to something like below:
roles/
webservers/
tasks/main.yml
vars/main.yml
templates/vhost.conf.j2
playbook:
***********
—
hosts: my_servers
roles:
- { role: webservers, vhost_name: www.sitea.com, vhost_root:
/var/www/sitea }
- { role: webservers, vhost_name: www.siteb.com, vhost_root:
/var/www/siteb }
task/main.yml:
****************
—
- name: copy vhost config
template: dest=/etc/httpd/conf.d/{{ vhost_name }}.conf src=vhost.conf.j2
sudo: yes
templates/vhost.conf.j2:
****************
<VirtualHost {{ ansible_eth0.ipv4.address }}>
DocumentRoot {{ vhost_root }}
ServerName {{ vhost_name }}
</VirtualHost>
cheers,
fred
