configuration - Nginx: setting the error page to a static file -

i have following nginx configuration:

server {   listen          80;   server_name     default;    location / {     proxy_set_header host $host;     proxy_pass http://127.0.0.1:8080/;   }  } 

when internal service @ http://127.0.0.1:8080/ not responding nginx return 502 bad gatway error.

my question: how can configure nginx returning static html file, e.g. /var/www/error.html, when such error occurs?

what tried

taking cue from here tried this:

server {   listen          80;   server_name     default;    location / {     proxy_set_header host $host;     proxy_pass http://127.0.0.1:8080/;   }    error_page 404 502 /error.html;    location = /error.html {     internal;     root /var/www;   }  } 

it's working fine if service (on port 8080) down, when service , try access url /error.html nginx match last location (returning me static file) , avoid it.

well, if don't want expose error page, use named location.

server {   listen          80;   server_name     default;    location / {     proxy_set_header host $host;     proxy_pass http://127.0.0.1:8080/;     # need     # proxy_intercept_errors on;   }    error_page 404 502 @error;    location @error {     root /var/www;     try_files /error.html /error.html;   } }
