data publish timeout

[Murthy10]

Wenn auf einmal viel Daten publiziert werden (bsp. ganz USA) kann es auf dem Backend (Server) zu einem Timeout kommen. (http error 504)

2021/08/19 07:32:17 [error] 2315137#2315137: *16671 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 23.101.155.145, server: wc-guide-backend.wc-guide-backend, request: "PUT /area/russia/ HTTP/1.1", upstream: "http://172.17.0.2:80/area/russia/", host: "api.wc-guide.com"

Dies muss an der Dokku / nginx config angepasst werden.

Teillösung:

proxy_connect_timeout etc. in /home/dokku/wc-guide-backend/nginx.conf höher setzen. (service nginx reload)

  location    / {

    gzip on;
    gzip_min_length  1100;
    gzip_buffers  4 32k;
    gzip_types    text/css text/javascript text/xml text/plain text/x-component application/javascript application/x-javascript application/json application/xml  application/rss+xml font/truetype application/x-font-ttf font/opentype application/vnd.ms-fontobject image/svg+xml;
    gzip_vary on;
    gzip_comp_level  6;

    proxy_pass  http://wc-guide-backend-80;
    http2_push_preload on;
    proxy_connect_timeout 600;
