Accessing Templates There are two ways to render a template, based on a single host, or based on a Hostgroup. The host or hostgroup provides all the details with which to render the template. Host-based Rendering Only a single template of each type may be rendered for a system. Foreman determines which template to use following these rules: 1.

 For this example you need to create the following directories as best practices For example root  |  ---- group_vars  |  -----roles  |          |  |          ----common  |-- site.yml  |-- hosts Create the root directory in this example named ansible #mkdir  ansible create the group_var and roles directories #mkdir group_vars #mkdir roles Create the files site.yml and hosts # touch site.yml # touch hosts Too create the common directory change to the directory roles and execute the following command ansible-galaxy init common this command create the standard infrastructure directories for use with ansible playbook For this example i would like to put the sudoers files in some machines to get this result we need to go into the common directory and there go into the tasks directory you are going to find a file named main.yml open it and copy the following remember start the file with 3 --- this indicate the beginning of the YAML file --- - name: Sudo
