まえがき

  • Brotliがgzipよりいい感じらしいよ、と小耳に挟んだので試してみようと思った
  • docker上のnginxへのmodule追加方法を知らなかったので結構調べた

Docker環境構築

Dockerfileのコピー

$ mkdir -p /path/to/project-root/docker/nginx
$ cd /path/to/project-root/
$ curl -o docker/nginx/Dockerfile https://raw.githubusercontent.com/nginxinc/docker-nginx/master/modules/Dockerfile

docker-compose ファイルの設定

$ vim docker-compose.yml
docker-compose.yml
version: '3.7'
services:
  nginx:
    build:
      context: docker/nginx
      args:
        ENABLED_MODULES: brotli
    image: nginx-with-brotli:v1
    container_name: "brotli-nginx"
    ports:
      - "80:80"
    volumes:
      - ./docker/nginx/nginx.conf:/etc/nginx/nginx.conf

nginx.confの設定

docker/nginx/nginx.conf
 user  nginx;
 worker_processes  1;
 
 error_log  /var/log/nginx/error.log warn;
 pid        /var/run/nginx.pid;
 
+ load_module modules/ngx_http_brotli_filter_module.so;
+ load_module modules/ngx_http_brotli_static_module.so;
 
 events {
     worker_connections  1024;
 }
 
 http {
     include       /etc/nginx/mime.types;
     default_type  application/octet-stream;
 
     log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                       '$status $body_bytes_sent "$http_referer" '
                       '"$http_user_agent" "$http_x_forwarded_for"';
 
     access_log  /var/log/nginx/access.log  main;
 
     sendfile        on;
     #tcp_nopush     on;
 
     keepalive_timeout  65;
 
     #gzip  on;
+     brotli on;
     include /etc/nginx/conf.d/*.conf;
 }

実行と確認

$ docker-compose build
$ docker-compose up -d

レスポンスヘッダーを確認

  • Accept-Encoding: brを指定して、Content-Encoding: br が返ってくればOK
$  curl -H "Accept-Encoding: br" -I http://localhost
HTTP/1.1 200 OK
