Using CLI with Nginx behind Jenkins

[mpapo - Michaël Pailloncy]

Hi all,

We've an issue using CLI with Jenkins behind Nginx .

Jenkins URL : http://host:8081/ic

Nginx reverse proxy URL : http://nicely-named-host/ic

Nginx is configured like that : https://wiki.jenkins-ci.org/display/JENKINS/Jenkins+behind+an+NGinX+reverse+proxy 

With a browser, Jenkins responds correctly to all http requests. There isn't any reverse proxy configuration alert in http://nicely-named-host/ic/manage.

Command OK : java -jar jenkins-cli.jar -s http://host:8081/ic help

Command KO : java -jar jenkins-cli.jar -s http://nicely-named-host/ic help

Error: 

Exception in thread "main" java.net.ConnectException: Connection refused: connect

Does somebody have an idea why I can't connect to Jenkins using CLI if it's behind a reverse proxy ? 

Thanks in advance.

I didn't use that config for NGINX.  Here is my nginx.conf which is much simpler:


worker_processes  1;

events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;

    keepalive_timeout  65;


    server {
        listen       80;

        # Redirect all port 80 requests to Jenkins on
        # port 8180
        return 301 http://$host:8180/jenkins/$request_uri;
    }

}

 

If you don't mind having something simpler which just does HTTP 301 redirect

instead of the reverse proxy config, you can see if that works better for you.

Hi,

Thanks to share your config.

However, we would like to keep reverse proxy configuration for maintenance convenience.

Another idea why CLI doesn't work with Jenkins behind a reverse proxy ?

The bug is already tracked :  https://issues.jenkins-ci.org/browse/JENKINS-16345 

Sorry for the noise.
