Cockpit 161

category: release

Cockpit is the modern Linux admin interface. We release regularly. Here are the release notes from version 161.

New VMs can be created on Machines page

The Machines page now has a “Create New VM” button for installing a new libvirt virtual machine from a local or remote ISO image. It allows the user to set some basic properties such as memory and storage sizes.

Thanks to Dominik Perpeet and suomiy for this feature!

VMs running in Kubernetes can now be deleted

Cockpit 160 added an initial overview of kubevirt Virtual Machines. This page now got a first action to delete a running VM.

Thanks to Marek Libra for this feature!

Improve LVM volume resizing

Cockpit now knows upfront whether shrinking or growing an LVM logical volume is possible, and whether the filesystem needs to be unmounted. Since shrinking and growing are quite different in practice, the Storage page now shows separate “Shrink” and “Grow” buttons. See it in action:

Add new Hardware Information page

On the System page the “Hardware” name is now a link to a new “Hardware information” page. For now this shows information about the system name, form factor, CPU, BIOS, and PCI devices. Other types of hardware will be added in future versions.

Rename cockpit-ovirt package to cockpit-machines-ovirt

The previous package name collided with a package that is already available in Red Hat Virtualization Host. This only affects Fedora, as other operating systems do not ship the Cockpit ovirt extension.

Stop advertising and supporting cockpit-bundled jQuery library

Cockpit’s JavaScript API documentation previously had some outdated information about jQuery, suggesting that users of the Cockpit API should always load jQuery, and use the one bundled with cockpit.js. This has not been true for a long time, and was just forgotten to be cleaned up. Previously the Cockpit code examples also did that, misleading developers who used them as a starting point for their own modules.

Both the documentation and the examples got cleaned up now, and issues got filed on affected GitHub projects. From now on, please use your own jQuery module for your projects instead of cockpit’s bundled one. This avoids breaking your project when cockpit’s jQuery version gets updated.
