静的コンテンツ、例えば画像をS3に配置します。その画像のパスをDBに保存するときにドメインを保存しなくて、URIだけ保存しつつ表示させる方法です。

• Nginx(www.exampl.net) -> CloudFront -> S3(s3.hoge.com)

Nginx

$ sudo vi /etc/nginx/sites-enabled/homestead.test

server {
    listen 80;
    listen 443 ssl http2;
    server_name example.net www.example.net;
    root "/home/vagrant/code/public";

    index index.html index.htm index.php;

    charset utf-8;

    client_header_buffer_size 64k;
    large_client_header_buffers 4 64k;

    location / {
        try_files $uri $uri/ /index.php?$query_string;

    }

・・・

●これを追加

    location /images {
        try_files $uri @s3;
    }

・・・

    location @s3 {
        return 301 https://s3.hoge.com$request_uri;
    }

    location = /favicon.ico { access_log off; log_not_found off; }
