I am trying to set proxy_pass based on $host value, I tried this:

location /api/v1/ {
    if ($host = .*\.npreprod.company.com)
    {
            proxy_pass https://frontend-api.preprod.company.com/api/v1/;
    }
}

however, I got the error

nginx: [emerg] "proxy_pass" cannot have URI part in location given by regular expression, or inside named location, or inside "if" statement, or inside "limit_except" block in /etc/nginx/sites-enabled/nuxtjs.conf:45

so, what's the proper way to achieve this?

Does this answer your question? Nginx location regex doesn't work with proxy pass – AlexD Jan 03 '22 at 11:01
I don't think this is the correct duplicate. I'm pretty sure we already have one or more questions addressing the if is evil problem, but I can't find one right now. – Gerald Schneider Jan 03 '22 at 11:16
@AlexD I am not sure how would I apply the answer at that question in my case – simo Jan 03 '22 at 11:26
@GeraldSchneider this one describes how to match a hostname better https://serverfault.com/questions/286828/nginx-matching-server-host-name-in-location-directive – AlexD Jan 03 '22 at 11:43

Rather than testing the value of $host inside the server block, you could create a separate server block. See this document. – Richard Smith Jan 03 '22 at 12:34

Thanks@AlexD , yes, that's what I ended doing, it worked well. – simo Jan 03 '22 at 13:15
