Check if HTTP compression is enabled for large files

[dietervu]

The old discovery service leads to a download of 837 KB in total, the new one to 1.79 MB. As far as I can see, for none of the files the Content-encoding: gzip is returned by the HTTP server. This was the case for the old one. Would be good to optimize this before putting the new discovery service into production.

The problem seems to be fixed by adding following to the nginx config file inside the image (/etc/nginx/conf.d/discovery.conf) under the server context

    gzip              on;
    gzip_disable      "msie6";
    gzip_proxied      any;
    gzip_http_version 1.0;
    gzip_vary         on;
    gzip_min_length   200;
    gzip_buffers      16 8k;
    gzip_types        text/plain
                      text/xml
                      text/css
                      text/comma-separated-values
                      text/javascript
                      application/javascript
                      application/x-javascript
                      application/atom+xml
                      application/json
                      application/xml;

Confirmed that compression is now enabled.

Is the change persistent? I did not figure out how to persist the change.

As @andmor mentioned this has to be included in the nginx serving the static javascript: https://gitlab.com/CLARIN-ERIC/docker-aai-discovery/tree/new
