Elastic CloudのKibanaをnginxでリバースプロキシする

概要

自ドメインとして扱いたかったため

Tips

• kibana_alias_domainに自分のドメイン
• kibana_hostにElastic Cloudのエンドポイント

コード

server {
    listen 80;
    server_name {{ kibana_alias_domain }};

    location / {
        if ($request_method = 'OPTIONS') {
            add_header Access-Control-Allow-Origin '*';
            add_header Access-Control-Allow-Methods 'GET, POST, PUT, DELETE';
            add_header Access-Control-Allow-Headers 'Origin, Authorization, Accept, Content-Type, cache-control, X-CSRF-TOKEN, kbn-xsrf';
            add_header Access-Control-Allow-Credentials 'true';
            return 204;
         }
        proxy_pass {{ kibana_host }};
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        add_header Access-Control-Allow-Origin '*';
        add_header Access-Control-Allow-Methods 'GET, POST, PUT, DELETE';
        add_header Access-Control-Allow-Headers 'Origin, Authorization, Accept, Content-Type, cache-control, X-CSRF-TOKEN, kbn-xsrf';
        add_header Access-Control-Allow-Credentials 'true';
        rewrite /(.*)$ /$1 break;
    }

    error_page 500 502 503 504 /500.html;
    client_max_body_size 4G;
    keepalive_timeout 10;
}
