JIRA migration this weekend

In continuing my infra upgrade work, this weekend I'll be migrating JIRA to another server.

This will make upgrade more manageable and testable. The service will be disrupted for a few hours. Check out our @jenkinsci on Twitter for up-to-the-minute status.

Once the migration is done, the next step is to upgrade them.

Jenkins User Conference - Agenda News

I have some exciting news -- The agendas have been posted for the Jenkins User Conferences (JUC) to be held at U.S. East (Alexandria, VA) and Europe (London). Take a look here to learn more about the talks, speakers and schedules.

As always, there is a great lineup of presenters ready to share their Jenkins stories: Peter Vilim will be presenting “Proving a First Class User Experience with Jenkins” at the U.S. East JUC, and Sander Kieft’s talk is called “Automating a Big Data Platform with Jenkins” at JUC Europe. Learn more about all 2015 JUC speakers and talks here. Explore the pages and see the who/what/where of all JUC 2015 locations!

JUC World Tour 2015 - Keynote Speaker News and Early Bird Tickets

The 2015 JUC World Tour dates are rapidly approaching. Since the community has grown so tremendously since last year, the JUC in each city will be the largest gathering of Jenkins users in that region.

Kohsuke will, as always, be the opening keynote speaker at each JUC. But, with the conference going from one to two days, I am happy to announce that Gene Kim will be another keynote on the second day! He is the author of The Phoenix Project and a thought leader in DevOps.

To have these two experts in one place will provide a great opportunity to talk about Jenkins as the foundation of continuous delivery and DevOps practices.

Confluence migration this weekend

For the past few weeks, I've burnt a lot of midnight oil to get Confluence containerized. The goal is to make Confluence upgrade more manageable and testable. In the proces, I've not only containerized Confluence, but also containerized some other services, including mock LDAP server, to be able to test the copy of the production Confluence dataset against newer versions of Confluence before upgrading production.

The infra team is currently targeting this weekend to migrate our current Confluence instance to this new container, and use the opportunity to move the service to a bigger system. Currently JIRA and Confluence has to live within 2.5GB RAM from the same host, and it's really stretching both services. The new box has 4GB of RAM, and we are splitting JIRA and Confluence to two different servers.

Good bye Java6

About two years ago, we bumped our runtime JRE requirement from Java5 to Java6. And so the time has come once again for us to finally move on to Java7. Because of all the new language features, many of us the developers really wanted to move right on to Java8, but after much discussion we settled to move to Java7 first and then to Java8.

So here is the plan:

  • Starting Jenkins 1.608, we start advertising that we will be moving on to Java7, which is why you are reading this.
  • Starting Jenkins 1.610 (2 weeks from now), we will ship so-called 51.0 class files that will only load on Java7+. This gives some more warnings to those who don't read our blog.
  • Unless we hear uproar from users, starting around 1.614 (6 weeks from now), core developers will start linking directly to new Java7 APIs.
