Have nginx return a 204 instead of 5xx

Question

I need my nginx front-end to return 204 when the back-end reply a 5xx or timeout.

Is it possible?

Thanks

Answer 1

Okay, finally I used:

location @return_204 {
    return  204;
}

location / {
        proxy_pass http://zzz;
        proxy_intercept_errors on;
        error_page 500 502 503 504 = @return_204;

}

Answer 2

You can use the error_page directive to achieve this. Not that you would also need to set proxy_intercept_errors to make Nginx process the errors.

location / {
    ...
    proxy_intercept_errors on;
    error_page 500 502 503 504 =204;
    ...
}
