Insert line in nginx configuration file ansible inside http {}

Question

I am writing an ansible script to deploy django in centos 7. My problem is with nginx.

I have created /etc/nginx/sites-available and /etc/nginx/sites-enabled directories and have to include sites-available in /etc/nginx/nginx.conf file at the bottom if http { } block.

How do I insert the line include /etc/nginx/sites-available/*.conf inside the http {} block in my ansible script after creating the respective directories and copying the configuration files?

The output should be

http {
    .....
    .....

    server {
        .......
    }

    include /etc/nginx/sites-available/*.conf;
}

You mean sth like http://docs.ansible.com/ansible/template_module.html ? — Wtower, May 09 '16 at 07:20
@Wtower The template might not work as I expect. I am going with lineinfile for now — Eutychus, May 09 '16 at 11:41
"might not work as I expect"? lineinfile will cause a lot more pain. — tedder42, May 09 '16 at 18:42

You can use the lineinfile module. Something like this should work:

- lineinfile: dest=/etc/nginx/nginx.conf regexp="^include /etc/nginx/sites-available/*.conf;" insertbefore="server {" line="include /etc/nginx/sites-available/*.conf;"

This will insert the line before the server block. You can play around with insertbefore and insert after and different regular expressions.

I think the issue with this is this has the potential to insert more than one line if there's more than one `server {` phrase defined in the default config. – Arcsector Dec 08 '22 at 01:54

Don't use lineinfile you will regret it at some point. Everybody does.

You should create a template and then load that with ansible.

#file: templates/nginx.conf.j2
http {
    .....
    .....

    server {
        .......
    }

    include /etc/nginx/sites-available/*.conf;
}

#file: main.yml
- name: "Load nginx config"
  template: src=nginx.conf.j2 dest=/etc/nginx/nginx.conf

This will make the management of your config much easier if you need to change anything in the config file.

I did not want to copy the whole nginx.conf file to a template just to add the include line. Are you advising that its the better solution that lineinfile? – Eutychus May 09 '16 at 11:40

yes, believe me, you will regret using `lineinfile` at some point ;) Having nginx.conf as a template is good anyway, you might want to change something later and you will have to do it anyway :) – shaps May 09 '16 at 15:52
