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.

Google Apps SSO no longer supported in Jenkins OpenID plugin

This is a guest post from Owen Mehegan (aka autojack)


In 2014 Google announced that they will be shutting down their OpenID 2.0 authentication endpoint and replacing it with Google+ Sign-in, a library built on top of OpenID Connect. The old Google endpoint will shut down on April 20th, 2015! Accordingly, if you are using the Jenkins OpenID plugin to authenticate users with the ‘Google Apps SSO’ feature (typically when Google hosts your personal or corporate email), you need to upgrade. Ryan Campbell took the initiative to develop the new Google Login plugin which implements the Google+ Sign-in functionality. This is the recommended solution going forward. Follow the steps here to configure it for your site. Note that you DON’T need to have a Google+ social network account/profile.
