Cockpit is the modern Linux admin interface. There’s a new release every week. Here are the highlights from this weeks 0.101 release.

Kubernetes Volumes

You can now set up Kubernetes persistent volume claims through the Cockpit cluster admin interface. These volumes are used to store persistent container data and possibly share them between containers. Each container pod declares the volumes it needs, and when deploying such an application admins configure the locations to store the data in those volumes.

Since the 1.6.0 release, the Atomic Developer Bundle (ADB) includes support for Mesos-Marathon as an orchestrator. This is in conjunction with the support for Mesos-Marathon that was added to Atomic App 0.3.0. This feature supports developers choosing to work with atomicapps on Mesos-Marathon.

Mesos Marathon is a distributed control system which can be used for container orchestration in large server clusters. Some Docker-based infrastructure teams use Mesos instead of Kubernetes. Learn more here:

Cockpit is the modern Linux admin interface. There’s a new release every week. Here are the highlights from this weeks 0.100 release. Even though 0.100 may seem to be a magical number … it’s really just the number after 0.99 :D

SELinux Troubleshooting

Cockpit can now help you troubleshoot SELinux problems, and show you fixes for repairing the various issues. This is pretty amazing for system admins who really would rather be secure, but keep bumping into stuff that SELinux is blocking. There’s more to come on both SELinux and troubleshooting in the future. Take a look at what landed in this release:

Image Registry Interface

There’s a new Image Registry user interface. It works with Atomic Platform or Openshift clusters. By default this shows up in the Cockpit Cluster admin dashboard.

But more importantly you can deploy this as a standalone image registry, complete with storage, authentication and an interface. See www.projectatomic.io/registry for more info.

Here’s a quick demo:

Storage sliders and more

Marius has been working on cleaning up the storage UI. One of the changes you’ll notice is that you can now use a slider to choose a size for new volumes or file systems, and specify the size units you want to use:

Debian builds now also include the Storage page.

From the future

Peter worked on adding Cluster storage configuration to the Kubernetes admin dashboard. Basic support will be in the next release. Here’s a screenshot:
