During the hackathon we have created https://github.com/jenkinsci/blueocean-plugin/blob/master/Dockerfile.jdk10 . Now it needs to be expanded to Java 11 and added to the common release flows

Acceptance: 

• Create official Docker packaging for Java 11 which runs OOTB
• Update jenkins.io documentation to reflect the new repo: https://jenkins.io/doc/book/installing/#downloading-and-running-jenkins-in-docker  

Approach 1:

• Promote https://github.com/oleg-nenashev/jenkins-blueocean-experimental to jenkinsci
• Setup new DockerHub repo with Automatic build, e.g. jenkins/blueocean which is unused
• Define naming strategy
• Create Java 8 and Java 11 branches there, similar to the source repo

Approach 2:

• We could replace https://github.com/jenkinsci/blueocean-plugin/blob/master/Dockerfile.jdk10 by the new file and make it a part of the Default build by the Docker team
• Update scripts to do build/deployment of the second Dockerfile

It needs agreement with the BlueOcean team.
