Maintenance Window - ci.jenkins.io - 2019/03/06 - 9AM UTC+2

[Olblak]

Hi Everybody, 

The platform sig has been working hard on running jenkins with java11 and it's now time to use it in a real life scenario. 

Adrien Lecharpentier and I will upgrade ci.jenkins.io next Monday 3th of June at 9AM UTC+2.

As usually with such maintenance, we'll communicate in different ways:

* We'll be on a call using Google Meet and on irc #jenkins-infra

* We'll notify on this mail thread and update INFRA-2115 when the migration is done.

In short we'll execute following steps:

* Set jenkins master in maintenance mode "Prepare for shutdown"

* Backup jenkins home

* Update JAVA_OPTS with options specific to java11

* Move from the docker image jenkins/jenkins:lts-alpine to jenkins/jenkins:jdk11

* Ensure linux/windows agents use the same major java version than master ( java 11 )

Remark: We won't (voluntarily ) modify the other jenkins instances, at least for this maintenance window.

Cheers

Hi Everybody, 

I am happy to announce that ci.jenkins.io is now running on Java 11.

Thanks Adrien Lecharpentier and Baptiste Mathus for their help during the migration and more globally thanks to all the people

involved in the platform-sig for their work on jenkins running on java 11.

Excepted minor issues that we fixed  during the migration, upgrading from jdk8 to jdk11 was really easy.

In short we executed following steps:

• Set jenkins master in maintenance mode "Prepare for shutdown".
  
• Backup jenkins home, yolo
  
• Update JAVA_OPTS with options specific to java11 as defined here mainly related to the garbage collector
  
• Move from the docker image jenkins/jenkins:lts-alpine to jenkins/jenkins:lts-jdk11
  
• Restart Jenkins
  

• Ensure linux/windows agents use the same major java version than master ( java 11 )
  

For the windows agent we had to change the init script to use zulu11.31.11 instead of zulu8.28.0.1

And the linux agent was already using java11 anyway since we upgrade the agent to ubuntu 18.04

As usual, feel free to report any issues that you may have about ci.jenkins.io, on issues.jenkins-ci.org using the 'infra' project.

Remark, upgrading the other jenkins intances to java11 is not yet planned.

Cheers

Thank you Olivier.

A side note on the report of issues: please make sure to use the label `java11` so it can popup in different filters.

BR,

Thanks to everybody who contributed to this migration!

Adoption of Java 11 should give us some gradual improvements in the infrastructure, especially for Docker-based flows.

I also wonder about using Zulu for Windows agents. Should not we move to AdoptOpenJDK as it was discussed in https://groups.google.com/forum/#!msg/jenkinsci-dev/ae71SSLtdU4/ZUjNn3CsAgAJ ?

BR, Oleg

Hearty congratulations!  That's a great achievement.

+1

AdoptOpenJDK has been working great for me in both Windows and Linux environments.
