We are proud to announce the public beta of Trusty image. If you’re part of the Inner Circle, CircleCI’s beta program, you already have access!

What are Trusty images?

Ubuntu Cloud Images are pre-installed disk images that have been customized by Ubuntu engineering to run on cloud-platforms such as Amazon EC2, Openstack, Windows and LXC. The beta program enables you to run builds on Ubuntu 14.04 (Trusty) images. Currently, the builds run on Ubuntu 12.04 (Precise).

Benefits of using Trusty images?

Here are some benefits on why you should use Trusty:

  • You can now install newer Debian packages
  • Language support with latest major and minor versions

How to enable Trusty images?

To enable Trusty images, navigate to: “Project Settings” -> Tweaks -> “Experimental Settings” -> ‘Ubuntu 14.04 Trusty container’

Operational focus

Since Trusty image is still in beta, there can be certain performance issues. There may be instances when you may experience long build queues. However, our team will try our best to ensure successful completion of all builds.

Pre-installed packages

New Trusty images include updated versions for majority of languages with latest path levels. For a comprehensive list please click here. Example: Python 2.7.11 excludes2.7.10.

You can still use a version that is not pre-installed, however the installation will happen at the build time. Previously, if you wanted to use newer versions of packages/languages you need to install them manually, with the new Trusty image, a lot of them are pre installed.
