Question How to overwrite existing nginxs configurations?

Hi,

I'm trying to setup my private docker registry with the public port 5000 on my server running Plesk. In the internet I found several tutorials. They all need to extend the nginx configuration line this:

server {
listen 80;
server_name SERVER_URL;
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;

location / {
if ($http_user_agent ~ "^(docker\/1\.(3|4|5(?!\.[0-9]-dev))|Go ).*$" ) {
return 404;
}

proxy_pass http://localhost:5000;
proxy_set_header Host $http_host; # required for docker client's sake
proxy_set_header X-Real-IP $remote_addr; # pass on real client's IP
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_read_timeout 900;
}
}

So far so good. I stepped now into the Additional nginx directives and tried to extend it like this:

location / {
if ($http_user_agent ~ "^(docker\/1\.(3|4|5(?!\.[0-9]-dev))|Go ).*$" ) {
return 404;
}

proxy_pass http://localhost:5000;
proxy_set_header Host $http_host; # required for docker client's sake
proxy_set_header X-Real-IP $remote_addr; # pass on real client's IP
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_read_timeout 900;
}

But I get always an error

Invalid nginx configuration: nginx: [emerg] duplicate location "/" in /var/www/vhosts/system/SERVER_URL/conf/vhost_nginx.conf:1 nginx: configuration file /etc/nginx/nginx.conf test failed

The nginx code itself seems to be ok, but what can I do to get to to work? And on a standalone system without Plesk it works too. So I expect that it has any conflicts with the Plesk configuration, but of course I don't want to hard-code any changes into configuration files outside the Plesk UI.

I appreciate any help.

Thx and best regards,
Lars

This usually happens when nginx Proxy mode is still enabled for a domain. Disable proxy mode and click the Apply button first and then add the additional nginx directives.
