idea/rfc: device screen in cockpit
by Martin Polednik 03 Dec '16

03 Dec '16

Hello, I have an idea for cockpit, but before thinking it further, I'm interested in hearing your opinions. I am oVirt developer mostly dealing with system stuff and this is something that could be useful in virtualization while also providing utility for administrators using cockpit. The idea is about new tab/plugin (not sure of the terminology) called 'devices', that would allow access to (hardware) devices as exposed by sysfs. The interface could be similar to 'Services' tab/plugin, showing a list of device names created from their physical location, similarly to libvirt's nodedev-list. After clicking on the name, new screen would be presented, showing additional information such as * physical address, * driver in use, * special capabilities (SR-IOV numvfs and totalvfs, NPIV max_vports, vports), * iommu group (possibly clickable to reveal all devices in given group), * vendor, vendor id, product, product id. Additionally, it makes sense to allow some basic operations: * unbinding from host driver, binding it to specific one (useful for local vfio-pci testing), * reattaching it back (one use case is that oVirt does not reattach devices automatically due to possible issues, needs user intervention), * setting numvfs, vports, * ... ? Do you find ideas above reasonable for cockpit? It is mostly in idea phase, and builds on development and requirements of oVirt. I personally believe that this could be useful for broader audience. Thanks, mpolednik

Limit access to a user, and specific functions
by Brian Dunbar 31 Mar '16

31 Mar '16

New to cockpit - a co-worker mentioned it last week and it seems pretty nifty. I'm curious if it's a good fit for a project of mine. I want to host Open Bazaar servers (https://openbazaar.org/). I'd _like_ to give my users access a GUI as 'a' user to run a limited set of functions such as .. * start / stop a service * look at a log file * run a predefined set of API calls using CURL * run a predefined script to backup a database Is Cockpit a good fit? ~brian

Idea: Administer Virtual Machines from Cockpit
by Marek Libra 31 Mar '16

31 Mar '16

Hi, I would like to hear your opinion on adding Virtual Machine status and management capability to the Cockpit. I've already played with this idea for some time. It lead me to a plugin providing such a functionality, but with dependency on the oVirt (VDSM). The plugin - lists all VMs running on the host, - displays some charts, statistics and other VM details - plus allows set of actions on them (so far basic - shutdown, restart, console, but can grow). With optional access to oVirt's engine, additional cluster-related functionality is made accessible: - list of VMs in a cluster, - VM run, - click-through to other cockpit running particular VM - ... In hindsight, there might be a better approach in contributing VM status&management to the Cockpit upstream, alongside with recent Docker or Kubernetes. As a starting point, a list of running VMs will be displayed and basic set of actions provided. Vision: implement in the Cockpit - similar functionality as is recently done for the desktop's virt-manager but with the benefit of revising the User Experience - allow monitoring&management of cluster VMs, if the host is part of any This feature would be libvirt-based, not VDSM - so no additional dependencies for Cockpit. The VDSM would be preferred service provider, if *optionally* installed on the host. Similar for oVirt's engine - if accessible then cluster-related functionality is provided (i.e. cluster VMs list, managed VM migration, run a VM "in a cluster", cockpit's VM detail click-through, etc.). Benefit for users: support for VM management out of the box with layered access to functionality as more advanced VM management tools are installed on a host Please share your ideas. Thanks, Marek

Cockpit 0.99
by Stef Walter 24 Mar '16

24 Mar '16

A summary of the Cockpit weekly release. Over the last two weeks that was 0.98 and 0.99 Kubernetes Cockpit Pod ---------------------- The Kubernetes cluster admin interface is now deployable as a kubernetes pod. Peter did a lot of work to make this happen. It's a good example of taking just one part Cockpit, containerizing it and running it in a completely different environment. You can use the commands listed here to run it: http://cockpit-project.org/guide/latest/feature-kubernetes.html Demo: https://youtu.be/OCbuzBe7Ems Locking down Cockpit with Content-Security-Policy ------------------------------------------------- Content-Security-Policy is like SELinux in your browser. You declare what your application is allowed to do, and the browser prevents other things from happening (like cross site scripting attacks). In the last couple releases, a strict policy was applied to the NetworkManager, Storage, Accounts, and Kubernetes parts of the interface. Change: https://github.com/cockpit-project/cockpit/pull/4061 Change: https://github.com/cockpit-project/cockpit/pull/4029 Change: https://github.com/cockpit-project/cockpit/pull/4021 Change: https://github.com/cockpit-project/cockpit/pull/4020 Debian packages --------------- Cockpit has been testing each change and release against Debian during continuous integration for a while. Lars recently added Debian binary packages that people can install. We're still looking for a DD packager to help take those tested packages and include them in Debian proper. There's documentation for how to use the Debian packages here: http://cockpit-project.org/running.html From the future --------------- The ability to troubleshoot SELinux in Cockpit is pretty exciting. Dominik has lots of the work in this area and it's nearly ready. Watch the video below. Once it's finished you'll be able to just click a button to resolve many (most?) SELinux issues found on a server. Change: https://github.com/cockpit-project/cockpit/pull/3962 Demo: https://youtu.be/s6C29f8dSRQ Garret designed a UI for using Docker with an LVM pool as you do on Atomic Host. That is: A UI for docker-storage-setup. I'm looking forward to this in Cockpit. Sneak peak here: https://raw.githubusercontent.com/cockpit-project/cockpit-design/9bd7086a4a… Get it ------ You can get Cockpit here: http://cockpit-project.org/running.html Cockpit 0.99 is available in Fedora 24: https://bodhi.fedoraproject.org/updates/cockpit-0.99-1.fc24 Or download the tarball here: https://github.com/cockpit-project/cockpit/releases/tag/0.99 Take care, Stef

Bug in creating symlinks for pkg/*
by Abhishek Gupta 15 Mar '16

15 Mar '16

Hi, Currently a package with a "name"(in manifest.json) causes the package loading logic from various package directories to fail. Instead of the first one (ie: ~/.local/share/cockpit) being used, the last instance of a package will be used (ie: /usr/share/cockpit) A fix will be running the following command- sudo rm -rf /usr/share/cockpit/realmd PR associated with the issue- https://github.com/cockpit-project/cockpit/pull/4011 Cheers Abhishek

Cockpit 0.97
by Stef Walter 14 Mar '16

14 Mar '16

A summary of the Cockpit weekly release. This week it was 0.97 Testing Fedora 24 ----------------- Cockpit started doing integration testing against the upcoming Fedora 24 release, and doing continuous delivery to Fedora 24 as well. Obviously this is in addition to operating systems like Debian, Atomic and RHEL. As you can imagine, there were tons of regressions, compatibility issues and API changes found and bugs filed against things like NetworkManager, Kubernetes, Atomic App, openssh and SELinux. Some of the packagers already have fixes, good for them. Change: https://github.com/cockpit-project/cockpit/pull/3936 Storage UI Behavior ------------------- Marius has been doing lots of work brushing up the storage interface. Cockpit now displays the correct IEC (ie: MiB) style units for most storage things, in addition to helpfully showing the base-10 units when looking in the details of actual disks. Change: https://github.com/cockpit-project/cockpit/pull/3944 Anne Mullern submitted a patch to prevent entering negative sizes for partitions. Change: https://github.com/cockpit-project/cockpit/pull/3925 More work in this area happening right now, and lots of discussion. Nicer sliders for example: Preview: https://raw.githubusercontent.com/cockpit-project/cockpit-design/master/sto… Content-Security-Policy ----------------------- Work on implementing the strict Content-Security-Policy is continuing. The docker Containers part of Cockpit now runs in strict mode. The term.js code was fixed to support Content-Security-Policy. This prevents javascript from being loaded from unexpected places, and being used as an attack vector against the server. It's a safety measure, sort of like SELinux for your browser. Change: https://github.com/cockpit-project/cockpit/pull/3951 term.js: https://github.com/chjj/term.js/pull/115 Get it ------ You can get Cockpit 0.97 in Fedora 24: https://bodhi.fedoraproject.org/updates/cockpit-0.97-1.fc24 Or via COPR for CentOS, RHEL, and earlier versions of Fedora: https://copr.fedoraproject.org/coprs/g/cockpit/cockpit-preview/ Or download the tarball here: https://github.com/cockpit-project/cockpit/releases/tag/0.97 Take care, Stef
