Cockpit is the modern Linux admin interface. We release regularly. Here are the release notes from version 153.
Add oVirt package
This version introduces the “oVirt Machines” page on Fedora for controlling oVirt virtual machine clusters. This code was moved into Cockpit as it shares a lot of code with the existing “Machines” page, which manages virtual machines through libvirt.
This feature is packaged in cockpit-ovirt and when installed it will replace the “Machines” page.
This release fixes a lot of small packaging issues that were spotted by rpmlint/lintian.

Add Applications page
This version introduces the “Applications” tool page. This is an extension point for third-party software to add themselves to the Cockpit interface, by shipping appropriate AppStream metadata.
Note that at the moment there are no real Cockpit applications available yet. For testing this feature on Fedora, Marius Vollmer provides a COPR repository that can be enabled with these commands:
dnf copr enable mvo/cockpit-app-freeipa dnf install appstream-data-mvo

Add automatic update configuration for dnf to Software Updates
On Fedora ≥ 26, the Software Updates page now offers to enable and configure dnf-automatic for automatic daily or weekly updates.
For now this is only shown if the
dnf-automatic package is already installed.
Future Cockpit versions will install that on demand, and also cover
Fix cockpit-bridge crash if /etc/os-release does not exist
Some environments (particularly Docker containers) might not have an
/etc/os-release file, which
cockpit-bridge previously required.

Cockpit is the modern Linux admin interface. We release regularly. Here are the release notes from version 151.
Support loading SSH keys from arbitrary paths
The User menu’s Authentication dialog now supports entering arbitrary paths to
SSH keys for adding to the SSH authentication agent. Previously this only
offered keys present in the standard
~/.ssh home directory.

Support X-Forwarded-Proto HTTP header for Kubernetes
Newer Kubernetes versions support reading the X-Forwarded-Proto HTTP header, which helps to determine whether or not a client used SSL to connect to an intermediate proxy, load balancer, or similar. Cockpit’s Kubernetes (Cluster) dashboard now sets this header. Earlier versions have already done that when hosted in OpenShift.
Fix Kubernetes connection hangs
The previous Cockpit release 150 introduced a regression when connecting to Kubernetes clusters. In some cases, like specifying a wrong server name or when the Cluster did not send Authentication Provider information, the connection attempt would hang indefinitely. This version corrects this bug.

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.

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:

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.

We’re organizing a Cockpit workshop in Berlin on the 19th and 20th of October, the two days preceding the All Systems Go! conference, the successor to last year’s systemd.conf.
The idea is to bring the Cockpit community together to help each other out in various areas relating to Cockpit. For example: getting started writing a module, tackling beginner tasks, or understanding Cockpit’s general architecture.
If you’re interested, please let us know that you’re planning on coming on the list and which topics you’d like to learn or teach about. This will help us to plan accordingly.
Also, spread the word if you like the idea!
Cockpit is the modern Linux admin interface. We release regularly. Here are the release notes from version 146.
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

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.

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.
