This role installs and configures the nginx web server. The user can specify any http configuration parameters they wish to apply their site. Any number of sites can be added with configurations of your choice.
This role requires Ansible 2.4 or higher and platform requirements are listed in the metadata file. (Some older version of the role support Ansible 1.4) For FreeBSD a working pkgng setup is required (see: https://www.freebsd.org/doc/handbook/pkgng-intro.html ) Installation of Nginx Amplify agent is only supported on CentOS, RedHat, Amazon, Debian and Ubuntu distributions.

}sites configured and no additional configuration.

The file name for the specific site configuration is specified in the hash with the key "file_name", any valid server directives can be added to the hash. Additional configurations are created in /etc/nginx/conf.d/

- index index.htmlInstead of defining a site config file using a list of attributes,
you may use a hash/dictionary that includes the filename of an alternate template.
Additional values are accessible within the template via the item.value variable.
- hosts: all
roles:
- role: nginx
nginx_sites:
custom_bar:
template: custom_bar.conf.j2
server_name: custom_bar.example.comCustom template: custom_bar.conf.j2:
Using a custom template allows for unlimited flexibility in configuring the site config file. This example demonstrates the common practice of configuring a site server block in the same file as its complementary upstream block. If you use this option:
- The hash must include a
template:value, or the configuration task will fail. - This role cannot check tha validity of your custom template. If you use this method, the conf file formatting provided by this role is unavailable, and it is up to you to provide a template with valid content and formatting for NGINX.
