Agenda:

• Open Action items
  • BlueOcean Docker container
• Latest Java releases - progress with installation and Jenkins development
  • Oct 18, 2023 Oracle patch day
    • Java 11.0.21
    • Java 17.0.9
    • Java 21.0.1
  • Built on top of Docker images by Temurin
    • Not available yet as a docker image for JDK17 windows
    • Another reason to maybe switch to using the binaries directly instead of inheriting from the Temurin Docker image
• Java 21 support
  • Jenkins enhancement proposal by Mark Waite.
  • Progress testing the top plugins with Java 21
    • 31 are now tested with Java 21 (Jenkinsfile modified)
    • 84 are known to work withxJava 21
    • 13 don’t work yet with Java 21 (too outdated, using gradle, not in jenkinsci organization)
  • Java 21 availability for hardware
    • Will Java 21 be available for s390x?
      • If not, then Jenkins will no longer support s390x after Oct 2025 (per the proposed 2+2+2 Java Support Plan JEP)
      • It should with JDK21.0.1+12. The early access beta show s390x is back. Confirmed in Adoptium’s Slack channel.
  • Java 21 in infra
    • Almost finished the transition to official 21.0+35.
    • End of week, no more early access versions, except for s390x
  • Java 21 in Docker images
    • Docker agent:
      • feat(Windows): add Java 21
      • switch supported architectures to GA Temurin jdk21 images
      • We now have JDK21 images or JDK21-preview images, depending on the CPU architecture/distribution
    • Docker inbound agent:
      • switch supported architectures to GA Temurin jdk21 images
      • We now have JDK21 images or JDK21-preview images, depending on the CPU architecture/distribution
    • Docker ssh agent:
      • We now have JDK21 images or JDK21-preview images, depending on the CPU architecture/distribution
    • Docker controller:
      • We now have JDK21 images, or JDK21-preview images, depending on the CPU architecture/distribution.
  • Docker images
    • Work on agent and controller images
      • Ssh-agent: a few version bumps leading to one new release (5.17.0)
        • Bump Debian Bookworm Linux version to bookworm-20231009
      • Docker-agent: quite a lot of work that lead to twelve (12!) releases, the last being (3181.v78543a_987053-1)
        • Bump the Jenkins remoting version
        • bump archlinux to base-20231001.0.182270
        • breaking change: set Java 17 as default
        • republish a last bullseye set of images as the previous ones labelled bullseye were erroneously based on Debian bookworm since the 3148.v532a_7e715ee3-6 release
      • Inbound-agent: a lot of work, resulting in twelve new releases, the last being 3181.v78543a_987053-1:
        • Bump the parent image
        • breaking change: set Java 17 as default
      • Controller, with two new releases 2.428, 2.414.3):
        • breaking change: set Java 17 as default for LTS
          • This means that images with short tags (without “jdk” in them) like jenkins/jenkins:2.414.3 or jenkins/jenkins:2.414.3-alpine amongst other are using Java 17 and not Java 11 like in previous version.
          • If you need to keep using Java 11, you’ll have to use (for example) the tags jenkins/jenkins:2.414.3-jdk11 or jenkins/jenkins:2.414.3-alpine-jdk11.
          • This is displayed in a banner on the LTS, thanks to Hervé le Meur
        • Bump Debian Bookworm Linux Version to 20230919
        • bump ubi8/ubi to 8.8-1067
        • Use Alpine Linux 3.18.4
