Chapter 41. Red Hat Enterprise Linux Atomic Host 7.2.3

Cockpit has been rebased to version 0.96

Cockpit packages that are part of Red Hat Enterprise Linux Atomic Host 7.2.3 include cockpit-bridge, cockpit-shell, cockpit-docker, and cockpit-ostree. Other cockpit-related software can be added to a Red Hat Enterprise Linux Atomic Host via containers (such as the rhel7/cockpit-ws container). Cockpit 0.96 is compatible with docker 1.10.

This version fixes previous bugs with memory leaks, mostly related to DBus, and various navigation and connection issues. Also, you can now limit concurrent authentication similar to ssshd using the MaxStartups setting.

New sub-commands added to the atomic CLI

The atomic command-line tool for managing Atomic systems and containers now includes the "top", "diff" and "migrate" sub-commands. For more information on the syntax and usage, see https://access.redhat.com/documentation/en/red-hat-enterprise-linux-atomic-host/version-7/cli-reference/#cli_commands.

Support for customization of the host system

The new atomic-pkglayer packages contain a tool to install debug packages on Atomic Host systems. It is intended only for use inside the Red Hat Enterprise Linux Atomic Tools container image (rhel7/rhel-tools). It provides a mechanism to add RPM packages to an Atomic Host by allowing you to include them in local ostree layers on the existing system. See Installing RPMs on an Atomic Host with atomic-pkglayer for a description of the atomic-pkglayer tool.
