This month we were working on shutting down our container-based build environment in order to provide a more streamlined Linux Build Environment on our virtual-machine based infrastructure. Following on our blog post on the project, we wanted to say that we just completed this project!
Going forward, Linux builds will always run in a full virtual machine (formerly the
sudo: required infrastructure). You will always have access to elevated privileges (
sudo) within that container as well as the tools that depend on it, such as Docker.
