Cockpit is the modern Linux admin interface. We release regularly. Here are the release notes from versions 149 and 150.
Add information about unmet conditions for systemd services
Systemd units can have conditions which must be met in order for the service to start. Cockpit now shows unmet conditions in the details of a service, so that users can see why a service is in active.
Automatically enable and start newly created timers on the Services page
Cockpit allows the user to create custom systemd timers on the Services page, to run commands at particular times or after boot. Previously they had to be explicitly enabled and started to become effective; this now happens automatically.
Support Kubernetes authentication providers in kube config files
Some kubernetes deployments such as Google Compute Engine use Kubernetes authentication providers so that they can automatically regenerate their access token when needed. Cockpit now supports kube config files using this format.
Support sending non-maskable interrupt to VMs
The Shut Down button on the Machines page got a new option “Send Non-Maskable Interrupt”. This normally does not trigger a reaction (other than a kernel message), but the Linux kernel can be configured to react to this with a kernel panic. This allows administrators to debug hung virtual machines.
Support Dashboard installation into OSTree overlay
The cockpit-dashboard package can now be installed as package overlay into rpm-ostree. This enables managing multiple remote servers through one Cockpit instance on Atomic based systems.
Clear cockpit cookie on logout
Previously, after logging out (explicitly or due to session timeout) it could happen that revisiting a seen page would show a cached version instead of the login page. This has now been fixed by properly clearing Cockpit’s browser cookie.

Support Cockpit in Internet Explorer
Update Cluster/Registry design for image streams
The design of the image streams on the Cluster and Registry pages has been updated to match the design of the current OpenShift Web Console.
Delete OpenShift session tokens on logout
If the Registry Console or Dashboard creates a new OpenShift session token on login, it will now delete that token again on logout. This behaviour now matches what the OpenShift Web Console does.
Detect unregistered RHEL systems on Software Updates page
On RHEL systems which have not yet been registered or whose registration expired, the Software Page would previously have claimed that “the system is up to date”. Now it detects if the system is unregistered and thus cannot receive updates:

Add configuration of expiry to Accounts page
The Accounts page can now display and change the expiration of user accounts and their passwords. Note that the login page supports changing expired passwords.

Thanks to Fridolin Pokorny for this improvement!
Consistently ignore loopback traffic on all network load graphs
The network load graphics on the System, Networking, and Dashboard pages
sometimes accounted traffic on the loopback network device (
lo), which in
most cases is not interesting for administrators. Now the graphs always ignore
the loopback device.
Fix the Kdump page in Internet Exporer

Software Updates page shows more information
The Available Updates and Restart recommended pages now show the packages from the previous update run. This makes it easier to see which services to check or to decide whether a restart is really necessary:
The new Update Log expander shows the previous steps of the running update:
Improve available Software Updates layout for small/mobile screens
The Available Updates page now folds all information into a single column on very narrow/mobile screens, to stay readable:
In addition, updates with a long changelog or a large number of subpackages now
get truncated, with a
More information… expander. This avoids lots of empty
space that makes it difficult browse the updates list.
Support OAuth Kubernetes logins with Google Compute Engine
The Kubernetes pages (Cluster) can now log into Google Compute Engine. Note
that there is no way to get information about the user, so they are being
Fix reporting ABRT crashes that are already known to the server
Trying to report a crash (
Problems category on the Logs page) that the FAF
server already knows previously caused an error message. This has been
corrected, and the report is now properly shown as
Thanks to Matej Marušák for this fix!
Scroll the virtual machine VNC console into view automatically
When opening the builtin VNC console of a virtual machine, the page now automatically gets scrolled to maximize visibility of the console.
Thanks to Marek Libra for this improvement!

Cockpit 146 is available now:
Cockpit is the modern Linux admin interface. We release regularly. Here are the release notes from version 144 and 145.
The Terminal now uses the full window size and dynamically resizes with it. Previously its size was fixed to 80x24 characters.
Machines page reactiveness
The Machines page now listens to libvirt events instead of reading the entire
state of all virtual machines every ten seconds. This makes the page much more
reactive to state changes and reduces the number of calls to
Delete VM functionality
A “Delete” button/dialog was added to the Machines page. If the VM is still running, it will be force-stopped first. The dialog also offers you the choice to remove the VM’s disk images as well.
Retire external Machines provider API
Cockpit 132 introduced an external API for the Machines page that allowed third party plugins to dynamically add/manage virtual machines from providers other than libvirt. This was found to be not supportable in the long run and thus was discontinued.
On Fedora 26 the Logs Page now shows Problem reports from the ABRT crash reporting tool. They appear as new message class “Problem” in the journal view, and their details can be visited when clicking on them:
Thanks to Matej Marusak for this feature!
Always recommend restarting after applying Software Updates
Most supported operating systems in Cockpit don’t provide a reliable detection of whether they require restarting the machine after applying updates for them to fully take effect. This particularly affects updates to the kernel, but also restarting services. For now, Cockpit will always recommend to restart the machine after applying updates:
Cancelling Software Updates
The Software Updates page now has a Cancel button that is enabled while it is still safe to abort a running update, i.e. while the updates are still being downloaded.

Cockpit 145 is available now:
Last week a bunch of us met up in Karlsruhe in Germany to work on virtual machines support in Cockpit. We had some specialists there who helped us get up to speed with VMs. Tons of pull requests opened, designs put together. Some of the changes are already merged and released in Cockpit 144.
Marek helped all of us understand how Redux stores and models data. The oVirt folks are using Redux a lot in front end code and want to be able to share code. Marius managed to reconcile Redux with our dialog and promise code.
Creating virtual machines is hard. There’s a surprising amount of strange little details and corner cases. Andreas, Garrett, Pavel, Dominik and Michal were involved in long discussions about how to make this work. And Dominik opened a pull request.
Marius added functionality to Delete virtual machines from the Cockpit UI.
And there were more pull requests and discussions, but I’m running out of space.
There’s a Cockpit Hackfest underway in Karlsruhe, Germany. We’re working on the virtual machine functionality in Cockpit.
At the same time, Martin is working on making the current virsh based access to libvirt more performant, so we don’t block on waiting until the DBus wrapper is done.
Lots of work was done understanding redux. The initial machines code in Cockpit was written using redux, and we needed to map it’s concept of models and state to the Cockpit way of storing state on the server and UI concepts like dialogs. Everyone was involved.
Andreas, Garrett have been working on designs for creating a virtual machine and editing virtual machines. Dominik started work on implementing that code.
Marius worked on deletion of virtual machines, and already has a pull request open.
Stef worked on the integration tests for the virtual machine stuff and is booting nested VMs using nested images.
Cockpit is the modern Linux admin interface. We release regularly. Here are the release notes from version 143.
“Software Updates” page for package based operating systems
There is a new “Software Updates” page for classic dnf/yum/apt based systems,
to complement the already existing one for OSTree on
Atomic. This uses the PackageKit
API for platform
independence. This feature is shipped in the new

Inline VNC consoles
The inline VNC console advertised in Cockpit 142
was not actually working from the released
cockpit-machine package due to a
packaging problem. Cockpit 143 corrects this problem. Thanks to Marek Libra!
Kubernetes RBAC authorization support
The Kubernetes page can now be used to log into Kubernetes installations that use RBAC authorization.
RPM packages for IBM Z systems
cockpit-docker RPM package is now being built on the s390x (IBM Z
Systems) architecture, as the Fedora Docker package is available there.

Virtual machines display an interactive console
The Virtual Machines page now offers easy access to graphical consoles in the new “Console” tab. If the VM has a VNC server enabled, then there is now an inline noVNC console:
If the VM only has a SPICE server, or the inline console is not sufficient, you can use “Switch to Desktop Viewer” and with a single button click open virt-viewer for that VM:

Document how to grant/restrict access via polkit rules
Users who are not administrators can normally not perform actions such as changing the hostname or start/stop systemd services. The Privileges and Permissions section in the guide and the systemd feature page now describe how to use polkit rules allow fine-grained permissions such as “that user can restart this particular service”.
Attempt to tear down used partitions when formatting disks
Trying to format a disk on the “Disks” page which still has partitions which are in use (mounted or used as an LVM physical volume) will now attempt to unmount/remove the physical volume, instead of just failing:

Reordered entries in the sidebar menu
As a followup to the new look, the entries in the sidebar menu have now been reordered in a more sensible fashion:
- System information
- Logs for troubleshooting
- Configuring major subsystems: Storage, Networking
- What’s running: Containers and Virtual Machines
- Implementation details: Admin accounts, Services/Units
Check out the screenshot below to see how this looks now.
Storage management is more convenient
In order to make configuring storage more convenient, the Cockpit UI now prevents removing disks from a RAID when removal would lead to data loss due to an insufficient number of remaining volumes in the RAID. Also, when creating a Volume Group (LVM) or adding disk space to a Volume Group, unpartitioned space is now offered as a choice. If selected, Cockpit automatically creates a partition before adding it to the Volume Group. Check out the screenshots below to see how these features look.
Consider user known_hosts for ssh connections
When managing remote machines, Cockpit now considers known host keys in the user’s
~/.ssh/known_hosts in addition to
/etc/ssh/ssh_known_hosts. This makes Cockpit behave more like the standard ssh client.
