Agenda:

• Open Action items:

  • Docker Images
    • Container image deprecation for the blue ocean container (jenkinsci:blueocean)
      • https://hub.docker.com/r/jenkins/blueocean - no tags
      • Docker - has
      • Need to announce the deprecation of the image
        • Update the page on Dockerhub
        • Add to a Jenkins LTS changelog or upgrade guide?
        • Add a disclaimer to one or more pages on www.jenkins.io?
          • Update the 2017 Blue Ocean blog post with deprecation notice?
      • Report it on it regularly in Platform SIG meetings
      • Create an issue that proposes the deprecation
    • Some of the README files are now being synced with DockerHub, so that may be one of our leverage points to communicate with the end users.

• Ongoing work

  • JDK21
    • Infrastructure
      • We’re working with updatecli to keep the JDK21 updated to an early access version before the official launch

• Java 11, 17, and 21 with Jenkins

  • See Mark Waite’s Google Doc that is a draft
    • Draft sent to the Jenkins officers
  • As a pic is worth a thousand words: diagram
  • Needs further discussion and refinement before it is final

    • First JDK 21 preview images
  • Docker-agent: a few version bumps too, and a breaking change, resulting in three releases (3148.v532a_7e715ee3-2, 3148.v532a_7e715ee3-3 and 3148.v532a_7e715ee3-5)
    • Breaking change: use a ltsc2019 base image for windowsservercore-ltsc2019 agent images
    • Bump JDK11 version to 11.0.20.1_1
    • Bump JDK17 version to 17.0.8.1_1

  • Inbound-agent, a few versions bumps, resulting in two new releases (3148.v532a_7e715ee3-4 and 3148.v532a_7e715ee3-5):
    • Breaking change: use a ltsc2019 base image for windowsservercore-ltsc2019 agent images and add a nanoserver-ltsc2019 image
    • Add preview images for jdk21, even for Alpine
    • Bump the parent image jenkins/agent version to 3148.v532a_7e715ee3-5
  • Controller, with 2 new releases (2.421and 2.422):
    • Bump ubi9/ubi and ubi8/ubi
    • Bump eclipse-temurin to 17.0.8.1_1-jdk-ubi9-minimal
    • Bump eclipse-temurin to 11.0.20.1_1-jdk-centos7
      • Centos7 is convenient, but we really should switch from Centos7 to … Ubi8? Or build it from the JDK binary instead of another image? => let Bruno test it…
    • Bump eclipse-temurin to 11.0.20.1_1-jdk-centos7
