The CentOS Atomic SIG has released an updated version of CentOS Atomic Host (7.1712), a lean operating system designed to run Linux containers, built from standard CentOS 7 RPMs, and tracking the component versions included in Red Hat Enterprise Linux Atomic Host.
This release includes updated kernel, linux-firmware and microcode_ctl packages to address recent security advisories, alongside other minor updates that shipped during the month of December.
CentOS Atomic Host includes these core component versions:
Download CentOS Atomic Host
CentOS Atomic Host is available as a VirtualBox or libvirt-formatted Vagrant box, or as an installable ISO, qcow2 or Amazon Machine image. For links to media, see the CentOS wiki.
If you're running a previous version of CentOS Atomic Host, you can upgrade to the current image by running the following command:
# atomic host upgrade
The CentOS Atomic Host image follows the upstream Red Hat Enterprise Linux Atomic Host cadence. After sources are released, they're rebuilt and included in new images. After the images are tested by the SIG and deemed ready, we announce them.
CentOS Atomic Host is produced by the CentOS Atomic SIG, based on upstream work from Project Atomic. If you'd like to work on testing images, help with packaging, documentation -- join us!
The SIG meets every two weeks as part of the Project Atomic community meeting at 16:00 UTC on Monday in the #atomic channel. You'll often find us in #atomic and/or #centos-devel if you have questions. You can also join the atomic-devel mailing list if you'd like to discuss the direction of Project Atomic, its components, or have other questions.
If you run into any problems with the images or components, feel free to ask on the centos-devel mailing list.
