Dear all, I know the subject is not new, but I have not been able to find a solution to my problem. Even after reading Jenkins behind a reverse proxy <https://wiki.jenkins.io/display/JENKINS/Jenkins+behind+an+NGinX+reverse+proxy> .
As a docker training exercise, I try to setup a mockup with 2 containers. - One with nginx nginx is used as a reverse http proxy (the next step wil be https frontend) - One with jenkins jenkins is supposed to be publicly accessible as www.devportal.org:90/ci, but is *internally *(i.e. within the *docker network) *known as jenkins_ci thanks to docker network alias. I have added ---prefix=/ci to the JENKINS_OPTS environment variable. I have partially succeeds. I mean that I can access it with the given address. But ... - When I try to connect as a user (the admin user), I get the login page. But when filling the user / password, I am redirected to http://www.devportal.org/ci/. In other words, the domain name and the prefix are OK, but* the port number is lost*. - If I add the port to this address on the location bar, I am correctly connected as the admin user, and the home page is correctly displayed. - When I select the manage page, I see a warning message saying that my* reverse proxy configuration is broken*. - Besides, when going to configure system, the page is displayed but *it never finishes loading*. - Also, on the jenkins logs, I see the following eror message : Jul 22, 2019 4:13:34 PM hudson.diagnosis.ReverseProxySetupMonitor getTestForReverseProxySetup WARNING: http://www.devportal.org/ci/manage vs. http://www.devportal.org:90/ci/manage I have checked that the Jenkins URL in the Jenkins location section is correctly configured as www.devportal.org:90/ci. And my nginx configuration is : server { listen 90; listen [::]:90; server_name www.devportal.org; access_log /var/log/nginx/reverse-access.log; error_log /var/log/nginx/reverse-error.log; location ~ "^/static/[0-9a-fA-F]{8}\/(.*)$" { #rewrite all static files into requests to the root #E.g /static/12345678/css/something.css will become /css/something.css rewrite "^/static/[0-9a-fA-F]{8}\/(.*)" /$1 last; } location /ci/ { proxy_pass http://jenkins_ci:8080; proxy_set_header Host $host:$server_port; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; # Fix the "It appears that your reverse proxy set up is broken" error. proxy_set_header X-Forwarded-Host $host; proxy_read_timeout 90; proxy_redirect http://jenkins_ci:8080 http://www.devportal.org; # Required for new HTTP-based CLI proxy_http_version 1.1; proxy_request_buffering off; proxy_set_header Connection ""; # Clear for keepalivea } } So, for sure, as the port number is lost, I guess there is something wrong in the nginx configuration (and/ or jenkins ?), but cannot find where. I would be very thankful if someone could help me. Best Regards J-L -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
