How to install nginx-module-brotli?

Question

I have a server with ubuntu 20.04

But I am unable to install nginx-module-brotli for my nginx server.

Here are the commands I use to install Brotli for Nginx :

$ sudo apt install git gcc cmake libpcre3 libpcre3-dev zlib1g zlib1g-dev openssl libssl-dev
$ wget https://nginx.org/download/nginx-1.18.0.tar.gz
$ tar zxvf nginx-1.18.0.tar.gz
$ git clone https://github.com/google/ngx_brotli.git
$ cd ~/ngx_brotli
$ git submodule update --init
$ cd ~/nginx-1.18.0
$ ./configure --with-compat --add-dynamic-module=../ngx_brotli
$ make modules
$ sudo cp ./objs/*.so /usr/share/nginx/modules
$ cd

and

$ sudo nano /etc/nginx/nginx.conf

load_module modules/ngx_http_brotli_filter_module.so;
load_module modules/ngx_http_brotli_static_module.so;

ubuntu@ov-ert6:~$ sudo systemctl restart nginx

ubuntu@ov-ert6:~$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

When I test my site, it cannot find Brotli in the headers :

You need to run your site on top of HTTPS. Brotli doesn't support http protocol. Further information can be found in https://hacks.mozilla.org/2015/11/better-than-gzip-compression-with-brotli/
