Installation

Build the Jenkins BlueOcean Docker Image (or pull and use the one I built)

docker build -t myjenkins:2.41 -f Dockerfile.2.41 .

docker build -t myjenkins:2.45 -f Dockerfile.2.45 .

docker build -t myjenkins:lts -f Dockerfile.lts .

#IF you are having problems building the image yourself, you can pull from my registry (It is version 2.332.3-1 though, the original from the video)

docker pull devopsjourney1/jenkins-blueocean:2.332.3-1 && docker tag devopsjourney1/jenkins-blueocean:2.332.3-1 myjenkins-blueocean:2.332.3-1

Create the network 'jenkins'

docker network create jenkins
