40.3. New Features
Beginning with the Atomic Host 7.2.4 release, two versions of the docker service will be included in the operating system: docker 1.9 and docker 1.10.
The following Knowledgebase article contains all information you need to know about using these two versions of docker: https://access.redhat.com/articles/2317361.
Introduced conflict between docker 1.9 and atomic-openshift 3.1 / origin 1.1 has been removed
Previously, due to stability issues between docker 1.9 and atomic-openshift 3.1 / origin 1.1, docker 1.9 has been packaged to conflict with atomic-openshift versions older than 3.2 and origin versions older than 1.2. As a consequence, running yum update on an OpenShift Enterprise 3.1 system failed due to that introduced conflict. This bug has been fixed, and running yum update now does not cause conflicts, successfully solves the dependencies and installs docker 1.9.
Updated kubernetes packages
Kubernetes updated to ose v3.2.0.16 corresponding to Kubernetes v1.2.0. Additionally, support for exposing secret keys in environment variables introduced.
Cockpit has been rebased to version 0.103
Most notable changes:
- When Cockpit fails to connect to a host, relevant SSH command or host details are now displayed to help resolve the issue.
- Docker restart policy can now be configured when starting a new container.
- Creating logical volumes has been combined into a single dialog.
- Joining IPA domains no longer offers a Computer OU option.
- Binary journal data is now displayed correctly.
- Disk or file system sizes are displayed using IEC names, such as MiB.
- Logical volumes can no longer be shrunk and the file system partition dialog prevents negative sizes.
- Strict Content-Security-Policy is implemented on most of Cockpit to prevent a number of browser based attacks. The packages also include numerous other bug fixes and admin interface improvements.
