I'm doing this on a DigitalOcean droplet Docker template from their marketplace.
I'm following these instructions. https://www.jenkins.io/doc/book/installing/docker
Follow these steps on the machine that has docker installed.
Create the network.
sudo docker network create jenkins
Run the docker-in-docker image. This allows execution of docker commands inside jenkins.
sudo docker run --name jenkins-docker --detach \
--privileged --network jenkins --network-alias docker \
--env DOCKER_TLS_CERTDIR=/certs \
--volume jenkins-docker-certs:/certs/client \
--volume jenkins-data:/var/jenkins_home \
--publish 2376:2376 \
docker:dind --storage-driver overlay2
Create a Dockerfile that adds to jenkins. This includes dependencies for .NET on Debian 11 (bullseye). The second apt-get line is the .NET dependencies.

USER jenkins
RUN jenkins-plugin-cli --plugins "blueocean:1.25.3 docker-workflow:1.28"
Build the docker image:
sudo docker build -t custom-jenkins-blueocean:2.339-1 .
Run the docker blue ocean container.
sudo docker run --name jenkins-blueocean --detach \
--network jenkins --env DOCKER_HOST=tcp://docker:2376 \
--env DOCKER_CERT_PATH=/certs/client --env DOCKER_TLS_VERIFY=1 \

--volume jenkins-data:/var/jenkins_home \
--volume jenkins-docker-certs:/certs/client:ro \
custom-jenkins-blueocean:2.339-1
Open a browser to <ipaddress>:8080. Finish the Jenkins install. Use the recommended plugins selection.
Click the Open Blue Ocean link on the left. Create a new pipeline. Select GitHub. Choose your organization and then repository. This repository should have a Nuke build project with execution engine 6.0.1. Complete the pipeline creation.
Click on a node to configure it. Choose Shell Script. Add this script.
./build.sh compile --configuration Release
Save the pipeline and run it if it didn't automatically start.
