Cockpit 326

Cockpit is the modern Linux admin interface. We release regularly.

Here are the release notes from Cockpit 326, cockpit-podman 96, and cockpit-files 9:

cockpit/ws container: Connect to any Linux server

The quay.io/cockpit/ws container provides Cockpit’s web server in environments such as Kubernetes and Fedora CoreOS, connecting to a remote machine via ssh.

Now, the cockpit/ws container gained the ability to connect to any Linux server, even those without Cockpit installed. This provides a convenient way to perform basic administration tasks remotely. This is similar to the Cockpit Client flatpak (available since release 295), but can run anywhere an OCI container can run.

Currently, the following pages are available when connecting to a server without Cockpit: Overview, Metrics, Terminal, Accounts, and Networking. More pages will be added soon, after vetting them for this use.

cockpit/ws container: Support host-specific SSH keys

The cockpit/ws container now supports adding multiple SSH private keys.

In addition to the existing $COCKPIT_SSH_KEY_PATH environment variable, you can now set host specific $COCKPIT_SSH_KEY_PATH_{HOSTNAME} variables, where {HOSTNAME} is the host name (in capital letters) used in the Connect to: field of the login page.

Thanks to benniekiss for contributing this feature!

Bridge supports PCP; cockpit-pcp package is now obsolete

The Python cockpit-bridge, introduced in Cockpit 294, now implements PCP functionality. As a result, the separate cockpit-pcp package is now obsolete.

Storage: Manage Stratis virtual filesystem sizes

Cockpit supports seting a default and maximum size limit for Stratis virtual filesystems, both during creation and when making adjustments.

Podman: pull images from registries without search API

Container creation now supports registries lacking a search API, including GitHub’s container registry (ghcr.io). You can also select a specific tag for images.

Files: basic keyboard shortcuts
