When: Friday February 6, 2014 at 14:10-17:10 Location: Room A113, Brno University of Technology, Brno, CZ We'll be helping folks figuring out how to hack on Cockpit, building some plugins or prototypes, and doing general scheming. If you want to get your feet wet (or dirty) this is the place to be. Devconf does not require an admission fee. Just come: http://devconf.cz Stef

cockpit-ws should require GLib 2.37.4 or later
by Stef Walter 12 Dec '14

12 Dec '14

Packagers of Cockpit might be interested in this pull request. We'll start to describe our dependency on GLib more accurately. Since versions of GLib before 2.37.4 crash with cockpit-ws, we'll refuse to build on those versions. https://github.com/cockpit-project/cockpit/pull/1586 This is the bug in question: https://bugzilla.gnome.org/show_bug.cgi?id=701283 https://bugzilla.redhat.com/show_bug.cgi?id=1143943 However if your distro has patched GLib to fix this bug (I think CentOS has done this), you can use the mechanism provided by pkg-config to override the check in question. This is described in the failure output of configure when this dependency are not met: > Alternatively, you may set the environment variables GLIB_TLS_CFLAGS > and GLIB_TLS_LIBS to avoid the need to call pkg-config. > See the pkg-config man page for more details. Cheers, Stef

Cockpit multi-host dashboard preview
by Stef Walter 11 Dec '14

11 Dec '14

Some people have asked (on IRC and in private emails) to see the Cockpit multi-host dashboard work, which includes some Kubernetes data. The goals of the dashboard are to answer and or help with: * What are my servers doing, and what is their health? * Did anything noteworthy happen since I last looked? * Quickly jump to the detailed view of a server and/or service. * Quickly correlate basic info of what is where, and where did this happen. Here's a screenshot with some explanations: https://cloud.githubusercontent.com/assets/795070/5395124/a1793a9e-8145-11e… Pull request is here: https://github.com/cockpit-project/cockpit/pull/1548 This is work in progress, but it actually mostly works ... lots of testing ... continuous integration setup ... polish needed before it can be merged.

Cockpit and VNC
by Stef Walter 05 Dec '14

05 Dec '14

I did a bit of a proof of concept for Cockpit showing a GUI remotely using noVNC. noVNC is a nice HTML5 VNC implementation. This is wrapped up as a Cockpit plugin ... and Cockpit provides the WebSocket, authentication, and all of that. It's very raw at this point ... but in case it piques anyone's interest. Screenshot: http://stef.thewalter.net/images/cockpit-vnc-example.png My current work on this will go as far as polishing up this pull request into Cockpit code example: https://github.com/cockpit-project/cockpit/pull/1560 Information on installing/creating plugins here, which you'll need to understand if you want to try this out. You'll also need Cockpit from git master, or wait until the next 0.34 release. http://stef.thewalter.net/creating-plugins-for-the-cockpit-user-interface.h… If someone has solid interest into building this into a full Cockpit feature, then they can work with the Cockpit team to prototype, plan (with use cases), design (with our designer: Andreas) and implement such a feature. Come to #cockpit or cockpit-devel(a)lists.fedoraproject.org Features built into Cockpit are expected to work out of the box and be discoverable. But I think that's within the reach of such a VNC based "access-a-gui-installer-remotely" use case, if someone puts enough time into it. Take care, Stef

Cockpit dependency on PCP without Avahi
by Stef Walter 04 Dec '14

04 Dec '14

We're working on using PCP to load server resource metrics in Cockpit. Is it possible to build pcp-libs without libavahi? It seems an odd feature for such a low level library to have ... as opposed to higher level PCP tools ... where dynamic discovery is interesting. cockpit-bridge is the piece of Cockpit proxies requests from the Cockpit Web a component we want to have as few barriers as possible. It's part of Cockpit that we want to be able to be installed on as many servers as possible. So we have to take a hard look at every single cockpit-bridge dependency, even the ones we currently have... Can we have /usr/lib64/libpcp.so without an Avahi dependency? Or should we treat PCP as an optional dependency of Cockpit and structure our code so that PCP is more of an add-on, used when available? What do you think? Stef

You can double check if you have the Container Administration group by looking for 'docker' listed in the command here: $ id When logged in as the same account (not root) via SSH, can you run docker commansd do you get a failure there too? $ docker ps What does the following command output: $ ls -l /var/run/docker.sock Hope that helps.
