Docker Windows Server Core Jenkins

DevOps Dockerized Windows Server Core with Jenkins, ASP.NET 4.8, .NET Core 3.1

WARNING: while this does build a Windows Server Core image there appear to be issues with Jenkins currently. I can get it to run but it's failing after project creation.

TODO: map in volume so jenkins data can be backed up.

Installer Files

I thought about this and decided it was best to run a PowerShell script before hand that downloads the installer files. Why did I do it this way? Had I done the download in the Dockerfile using PowerShell, it would have had to download all of those installers every time this image is re-created. You also have to log into Oracle to download the JRE SDK files. Rebuilding and customizing this image will be easier by mapping in the installer files since they are so large.

Getting Started. Building the Image

the "build.ps1" is a PowerShell script that downloads the installers and runs the Docker build command.

Run the Container

You may need to run docker login before you start.

Downloading the Installer Files

Running the downloadfiles.ps1 will download most of the files used to install and configure the build server. You will need to login to the Oracle website and download the JRE SDK in a tar.gz file format.

./downloadfiles.ps1

Starting Build Server

After you've built the image, you can create a container by runing the "run.ps1" PowerShell script.

./run.ps1

Initial Administrative Password

The initial password is in the logs of the docker container or you can use either one of these commands to get it.

docker logs jenkinsci

docker run -it jenkinsci type C:\Users\ContainerAdministrator\.jenkins\secrets\initialAdminPassword

Removing Container

docker rm -f jenkinsci
