Installing Jenkins on Windows with IIS. HTTPS configuration.

This post gives you an overview how to install Jenkins on Windows using IIS and reverse proxy.

Jenkins installation

Jenkins installation is pretty simple. Go to https://jenkins.io/, download the latest version of Jenkins for Windows and install it.

By default, Jenkins will be available on 8080 port. Open your browser and navigate to http://localhost:8080. It is the address where Jenkins is running.

Setting up IIS

To setup reverse proxy you need to install the following IIS plugins:

1. Application Request Routing
2. URL rewrite

Click on links above and you will be navigated to official installation source for both IIS plugins.

Reverse proxy for Jenkins

First of all, we need to create a new website. Create a new one with the name 'Jenkins'. After installation of IIS plugins, you should be able to configure a reverse proxy.

Follow the instructions from https://wiki.jenkins.io/display/JENKINS/Running+Jenkins+behind+IIS to setup HTTPS to HTTP reverse proxy for Jenkins.

HTTPS configuration

We will use Let’s Encrypt for certificate generation. Let’s Encrypt is a free, automated, and open Certificate Authority. And Certify tool to manage certificates.

1. Download from https://certifytheweb.com/ and install it.
2. Click 'New Certificate', choose your IIS site (which must have 1 or more hostname bindings set). Save your settings and click 'Request Certificate'
3. All done! Click 'Configure Auto Renew' to set up the scheduled task for renewals.

Conclusion

Now we have a basic setup for Jenkins on IIS with HTTPS support.
