38.3. New Features
Containerized core Kubernetes master services coming in 7.3 release
The Red Hat Enterprise Linux Atomic Host build will be further optimized for size and improved flexibility of Kubernetes version management starting with the 7.3 release. The core Kubernetes masters services (kube-apiserver, kube-controller-manager and kube-scheduler) will be installed as containers after Atomic Host is booted. Instructions on migrating to a containerized Kubernetes are available here and users should prepare for this in advance.
Cockpit has been rebased to version 0.114
Most notable changes:
- The protocol of cockpit-bridge and Cockpit’s javascript API is now stable. Plugins written against the javascript API should not experience changes from this point on.
- Red Hat subscriptions can now specify activation keys and organization.
- SSH Host keys are now shown on the system page.
- tuned is now disabled correctly when clearing a performance profile.
- Improved password score error messages are now displayed.
- An erroneous docker dependency has been removed from the cockpit package.
- Network configuration of the Ethernet Maximum Transmission Unit (MTU) is now available.
- The "active-backup" mode is now used as the default for new network bonds.
- Network interfaces where NM_CONTROLLED=no is set are no longer displayed.
The network on/off switch for unknown or unmanaged interfaces is now disabled.
The packages also include numerous other bug fixes and admin interface improvements.
