Add indent for nginx.conf

[danielqsj]

Currently, the generated nginx.conf looks like:

        location ~* ^/session-demo\/?(?<baseuri>.*) {
        set $proxy_upstream_name "sticky-org1-session-demo-80";

        set $namespace      "org1";
        set $ingress_name   "session-demo-test";
        set $service_name   "";

        port_in_redirect off;

        client_max_body_size                    "1m";

        proxy_set_header Host                   $best_http_host;

        # Pass the extracted client certificate to the backend

        # Allow websocket connections
        proxy_set_header                        Upgrade           $http_upgrade;
        proxy_set_header                        Connection        $connection_upgrade;

        proxy_set_header X-Real-IP              $the_real_ip;
        proxy_set_header X-Forwarded-For        $the_real_ip;
        proxy_set_header X-Forwarded-Host       $best_http_host;
        proxy_set_header X-Forwarded-Port       $pass_port;
        proxy_set_header X-Forwarded-Proto      $pass_access_scheme;
        proxy_set_header X-Original-URI         $request_uri;
        proxy_set_header X-Scheme               $pass_access_scheme;

        # mitigate HTTPoxy Vulnerability
        # https://www.nginx.com/blog/mitigating-the-httpoxy-vulnerability-with-nginx/
        proxy_set_header Proxy                  "";

        # Custom headers to proxied server

        proxy_connect_timeout                   5s;
        proxy_send_timeout                      60s;
        proxy_read_timeout                      60s;

        proxy_redirect                          off;
        proxy_buffering                         off;
        proxy_buffer_size                       "4k";
        proxy_buffers                           4 "4k";

        proxy_http_version                      1.1;

        proxy_cookie_domain                     off;
        proxy_cookie_path                       off;

        # In case of errors try the next upstream server before returning an error
        proxy_next_upstream                     error timeout invalid_header http_502 http_503 http_504;

        proxy_set_header                        Accept-Encoding     "";

        rewrite /session-demo/(.*) /$1 break;
        rewrite /session-demo / break;
        proxy_pass http://sticky-org1-session-demo-80;
        subs_filter '<head(.*)>' '<head$1><base href="https://$http_host/session-demo/$baseuri">' r;
        subs_filter '<HEAD(.*)>' '<HEAD$1><base href="https://$http_host/session-demo/$baseuri">' r;

        }

The indent is missing, the following looks good.

        location ~* ^/session-demo\/?(?<baseuri>.*) {
            set $proxy_upstream_name "sticky-org1-session-demo-80";

            set $namespace      "org1";
            set $ingress_name   "session-demo-test";
            set $service_name   "";

            port_in_redirect off;

            client_max_body_size                    "1m";

            proxy_set_header Host                   $best_http_host;

            # Pass the extracted client certificate to the backend

            # Allow websocket connections
            proxy_set_header                        Upgrade           $http_upgrade;
            proxy_set_header                        Connection        $connection_upgrade;

            proxy_set_header X-Forwarded-Host       $best_http_host;
            proxy_set_header X-Forwarded-Port       $pass_port;
            proxy_set_header X-Forwarded-Proto      $pass_access_scheme;
            proxy_set_header X-Original-URI         $request_uri;
            proxy_set_header X-Scheme               $pass_access_scheme;
