I'm writing ansible-playbook to divide nginx.conf with includes. In my opinion it would be more comfortable to use nginx.conf with such option cause I can include or exclude some config block at playbook vars.

At current time I have trouble with part: name: 2. Copy nginx.conf config.

playbook.yml:

- name: "setup_nginx"
 hosts: "TEST_HOST"
 gather_facts: yes
 remote_user: root

 vars:

 nginx_worker_processes: " ansible_processor_cores " 
 nginx_worker_connections: "32768" 
 nginx_worker_rlimit_nofile: "abs " 
 nginx_directories:
 - directory: inc
 nginx_files:
 - file: "gzip.inc" 
 - file: "logs.inc" 
 - file: "mime.types" 
 - file: "tuning.inc" 
 - file: "proxy.inc" 
 - file: "ssl.inc" 
 - directory: sites
 nginx_files: 
 - file: "mysite1" 
 - file: "mysite2" 
- tasks: 

 - name: 1. Create nginx directories
 file:
 path: "/etc/nginx/ item.directory "
 state: directory
 owner: nginx
 group: nginx
 with_items:
 - " nginx_directories "

 - name: 2. Copy nginx.conf config.
 template:
 src: nginx.conf.j2
 dest: /etc/nginx/nginx.conf
 mode: 0640
 owner: nginx
 group: nginx
 backup: yes
 with_subelements:
 - " nginx_directories "
 - nginx_files

nginx.conf.j2:

user nginx;

worker_processes ansible_processor_cores ; 

events 
worker_connections 32768; 
use epoll; 
multi_accept on; 


worker_rlimit_nofile int;

http 

% for val in nginx_directories %
include /etc/nginx/ item.0.directory / item.1.file ;
% endfor %

I expect result:

user nginx;

worker_processes 1; 

events 
worker_connections 32768; 
use epoll; 
multi_accept on; 


worker_rlimit_nofile 65536;

http 

include /etc/nginx/inc/gzip.inc;
include /etc/nginx/inc/logs.inc;
include /etc/nginx/inc/mime.types;
include /etc/nginx/inc/tuning.inc;
include /etc/nginx/inc/proxy.inc;
include /etc/nginx/inc/ssl.inc;
include /etc/nginx/sites/mysite1;
include /etc/nginx/sites/mysite2;

But actual result:

user nginx;

worker_processes 1; 

events 
worker_connections 32768; 
use epoll; 
multi_accept on; 


worker_rlimit_nofile 65536;

http 

include /etc/nginx/sites/mysite2.j2;
include /etc/nginx/sites/mysite2.j2;

I think the trouble is that I'm not correctly define subelements at template nginx.conf.j2.

Remove the loop in you template task and in your template use

% for val in nginx_directories 
include /etc/nginx/ val.0.directory / val.1.file ;
% endfor %

FWIW. There is an elegant solution with config_encoder_filters which encodes YAML data

my_nginx_vhost_config:
 - server:
 - listen 8080
 - server_name www.example.com
 - "location /":
 - root /usr/local/www/nginx-dist/
 - index index.html

with simple template

# ansible_managed 
 encode_nginx 

to nginx configuration

# cat /usr/local/etc/nginx/conf.d/default.conf
# Ansible managed
server 
 listen 8080;
 server_name www.example.com;

 location / 
 root /usr/local/www/nginx-dist/;
 index index.html;
 

Details are available in the nginx role.
