Hey folks - I'm at a conference and the internet here is... well... not very internetty. There are a number of folks here as well (Andy, Russell, David) who won't be attending either. That said, if anyone has stuff they want to do/talk about, go for it :) -robyn

Packaging of noVNC and Websockets
by Adam Young 08 Jun '12

08 Jun '12

It looks like a couple of projects are interested in using the noVNC viewer as a way of talking to machines from a web browser. I've made a first stab at packageing them, and, in doing so, learned a little bit. The noVNC code is designed around a proxy that, under the Debian deploy, lives in /usr/share/noVNC/utils/. This directory contains shell scripts, a shared object complete with Makefile, and lots of python code. Needless to say, it does not match Fedora packaging standards. It uses the Websocket protocol, which is not quite HTTP. Apache HTTPD does not support Websocket natively, although there is apparently a path to do so via http://code.google.com/p/pywebsocket/. However, the noVNC approach is to bundle a simple web server and websocket implementation. In addition, a python script called websockify handles SSL. When deployed, the web proxy does not lock down browsing of sub dirs. When run from an init script that did not set cwd, it exposes the entire directory tree underneath. The normal usage is better: devstack runs $ cd /opt/stack/noVNC && ./utils/nova-novncproxy --config-file /etc/nova/nova.conf --web . Run this way, it only exposes the /usr/share/noVNC directory as read only, but really should not allow directory indexing. However, our current init script runs: daemon --user nova --pidfile $pidfile "$exec --flagfile $config --logfile $logfile &>/dev/null & echo \$! > $pidfile" where $exec is /usr/bin/nova-vncproxy. In my spec file, in order to match this, I moved the executables from /opt/stack/noVNC/utils to /usr/bin, but that does not seem like a good long term solution: they are generically named and should have novnc as part of their name as well. I've also and renamed /opt/stack/noVNC/utils/nova-novncproxy to /usr/bin/nova-vncproxy which seems like it should not be necessary. Currently, the Openstack specific code is in the upstream git repo for noVNC, but it really should be moved to the Nova git repository. I'll talk to the original author to find out his rationale, and to see if we can get it moved over. I've posted my current work here http://admiyo.fedorapeople.org/noVNC/ But would not suggest that people use it yet. I am certainly willing to take feed back on the spec file: http://admiyo.fedorapeople.org/noVNC/novnc.spec Dan B suggested a few things that I'd like to record here: 1. Is there a need to create a novnc user with an empty home dir to run in? 2. The python code should be made into a site-package.

Re: [Openstack] centos 6 images

Joshua, First off, thanks for getting something together. I think you have a bug in your spec file at line 1. After that I got it to build after renaming some directories. I am in the process of testing this out now in a devstack install. I will give you feedback when I get it. jason ----- Original Message ----- From: "Joshua Harlow" <harlowja(a)yahoo-inc.com> To: "Jason Ford" <jason(a)chatinara.com> Cc: "Fedora Cloud SIG" <cloud(a)lists.fedoraproject.org>, "Andy Grimm" <agrimm(a)gmail.com>, "openstack" <openstack(a)lists.launchpad.net>, "Pádraig Brady" <P(a)draigBrady.com> Sent: Thursday, May 24, 2012 9:18:06 PM Subject: Re: [Openstack] centos 6 images Starting this @ https://github.com/yahoo/Openstack-Condense/wiki/How-To-Use-This I’ll try to finish it up soon :-P On 5/22/12 6:33 PM, "Joshua Harlow" < harlowja(a)yahoo-inc.com > wrote: Let me write something up that should explain this.

I tried to improve the following: 1. Code cleanliness (constants being uppercase, paths using os.path.join and so-on) 2. Stripping out some of the odd handlers (byobu, right-scale and such) 3. Improving logging by a lot (so that u can debug this thing) 4. Making what handlers I left work on RH and ubuntu... Might be useful if u want to try it. I know just from doing the above work that the cloud-init for ubuntu, requires some work to get it to work on RH, but not tons, eventually I hope that I can merge this back, but for now its forked so that I could focus on getting it working and cleaned up, rather than pushing code through some review process via launchpad and such (ie the slow as molasses approach).

Currently I have ssh keys getting imported but having some problems getting the disk to dynamically resize to the flavor template as well as the hostname set in horizon to be pushed into the image. Does anyone have any howtos or suggestions on how to get this done? Is there cloud-init for centos just like ubuntu?
