CentOS Project's Jason Brooks announced today, July 8, the general availability of a new maintenance update of the CentOS Atomic Host operating system designed to run Docker containers.
Built from standard CentOS 7 RPMs, CentOS Atomic Host has been updated to version 7.20160707, another important milestone that closely tracked the component versions included upstream in the Red Hat Enterprise Linux Atomic Host operating system, and includes many updated components.
The new updated software packages are Linux kernel 3.10.0-327.22.2.el7.x86_64, Docker 1.10.3-44.el7.centos.x86_64, Ostree 2016.5-3.atomic.el7.x86_64, Atomic run tool 1.10.5-5.el7.x86_64, Cloud-init 0.7.5-10.el7.centos.1.x86_64, Flannel 0.5.3-9.el7.x86_64, Kubernetes 1.2.0-0.12.gita4463d9.el7.x86_64, and etcd 2.2.5-2.el7.0.1.x86_64.
"An updated version of CentOS Atomic Host (tree version 7.20160707) is now available for download, featuring updated versions of docker (1.10.3) and the atomic run tool (1.10.5)," says Jason Brooks. "CentOS Atomic Host is available as a VirtualBox or libvirt-formatted Vagrant box, or as an installable ISO, qcow2 or Amazon Machine image."
