[14:56] <codec> hi
[14:57] <codec> i have a problem with my UEC. since my rootfs filled up i cant connect my CC to the NC (same host) anymore. node is registered but describe-availability-zones still shows 0000
[15:21] <codec> should there be any messages in nc.log after eucalyptus-nc startup?
[15:28] <codec> all i get in cc.log is  refresh_resources(): bad return from ncDescribeResource(172.18.0.2)

[18:07] <codec> woohoo
[18:07] <codec> i got my NC connected again, but now free reports 0000
[18:07] <codec> where max reports 0050 ...
[19:00]  * niemeyer anticipates people coming here..
[19:00] <kim0> = Ensemble weekly meeting =
[19:01]  * koolhead17 is present kim0 sir !! :D
[19:01] <kim0> Hi everyone
[19:01] <kim0> koolhead17: hey there
[19:01] <kim0> codec: hi
[19:01] <kim0> niemeyer: hi there as well :)
[19:01] <niemeyer> ;-)
[19:02] <kim0> So just some quick notes
[19:02] <kim0> The Ensemble ppa is now live
[19:02] <niemeyer> kim0: Tell us, what's up with the world of Ensemble
[19:02] <niemeyer> Woohay PPAs
[19:02] <kim0> All thanks to niemeyer for the great work
[19:02] <kim0> trying to find the actual ppa
[19:02] <niemeyer> You're welcome.. and thanks to Launchpad for enabling us to do this
[19:03] <niemeyer> I have to say that Daily Builds in Launchpad are *awesome*
[19:03] <niemeyer> sudo add-apt-repository ppa:ensemble/ppa
[19:03] <niemeyer> sudo apt-get update
[19:03] <niemeyer> sudo apt-get install ensemble
[19:03] <niemeyer> Profit
[19:03] <kim0> Awesome!
[19:03] <koolhead17> cool
[19:03] <kim0> niemeyer: I was thinking that I'd attack the "zero to Ensemble" scereencast right now
[19:03] <kim0> what do you think ..
[19:04] <kim0> from plain ubuntu .. to installing and launching wordpress from examples
[19:04] <niemeyer> kim0: I think hazmat is working on a screencast right now
[19:04] <kim0> oh cool!
[19:04] <niemeyer> kim0: Well, at least in the time I'm not pestering him with bugs
[19:04] <hazmat> indeed, pretty basic atm
[19:05] <kim0> hazmat: would be great if you'd write your name on one you want to do .. coz I'll do the rest
[19:05] <kim0> cool then
[19:05] <kim0> so the other piece of news is
[19:05] <kim0> the principia project is now principia-tools and principia is a distro now in launchpad
[19:05] <kim0> I could actually use some more explanations to what that entails
[19:06] <kim0> My understanding is each formula is a separate branch now
[19:06] <kim0> and that we can file bugs onto formulas
[19:06] <kim0> niemeyer: is that correct
[19:06] <niemeyer> kim0: That's right
[19:06] <niemeyer> kim0: This is part of the world domination plan
[19:06] <kim0> hahah
[19:07] <niemeyer> kim0: Which in technical terms means having a nice infrastructure for holding formulas in Launchpad
[19:07]  * kim0 nods
[19:07] <kim0> any other details to this distro thing
[19:07] <niemeyer> kim0: We want to enable a very smooth experience for pushing and consuming formulas
[19:07] <niemeyer> kim0: So each formula should be on its own branch
[19:07] <niemeyer> kim0: and we're working on more infrastructure to make good use of that
[19:08] <niemeyer> Sorry, I should be saying that to everyone rather than just kim0
[19:08] <kim0> the ensemble cli + server integration
[19:08] <niemeyer> Just too used to IRC conversations rather than presentations :)
[19:08] <kim0> correct ?
[19:08] <niemeyer> kim0: yeah
[19:08] <niemeyer> Yeah
[19:08] <niemeyer> :)
[19:08] <kim0> Sounds great
[19:08] <kim0> is there some path to someone contributing a formula currently
[19:09] <kim0> i.e. before the server integration stuff
[19:09] <kim0> For example I'm starting on a drupal formula and would love to merge it
[19:09] <kim0> and I know koolhead17 wants to start on one as well
[19:10]  * koolhead17 nods
[19:10] <kim0> koolhead17: How is it going for you
[19:10] <niemeyer> kim0: For now, just push a personal branch to Launchpad
[19:10] <koolhead17> kim0: am reading.
[19:10] <niemeyer> Anywhere in Launchpad
[19:10] <niemeyer> One formula per branch
[19:10] <kim0> Yeah that should be simple
[19:10] <koolhead17> i want to start with the simplest of all :)
[19:10] <niemeyer> If you do that, once the infrastructure starts working fully, it'll be trivial to integrate
[19:10] <kim0> koolhead17: have something in mind yet ?
[19:11] <kim0> niemeyer: thanks for clearing this
[19:11] <kim0> niemeyer: Is the PPA built daily
[19:11] <koolhead17> kim0: since wordpress/drupal is in process i can think of joomla
[19:12] <niemeyer> kim0: It is
[19:12] <kim0> awesome .. I may stop running from trunk then :)
[19:12] <niemeyer> kim0: Well, you'll continue running from trunk, just more comfortably
[19:12] <kim0> Yeah!
[19:12] <kim0> Ok that's it for news items
[19:13] <kim0> niemeyer: any recent development news you'd like to share
[19:13] <niemeyer> Config settings are almost merged
[19:13] <kim0> This should allow passing parameters to formulas
[19:14] <kim0> and is going to be great :)
[19:14] <kim0> sounds great
[19:14] <niemeyer> kim0: Exactly
[19:14] <niemeyer> Hopefully this week we'll have that in
[19:14] <kim0> woohoo
[19:14] <kim0> I see "dependency resolution" is in "Needs release" status
[19:14] <kim0> does that mean it's close
[19:15] <niemeyer> kim0: No, that's bogus..
[19:15] <kim0> ah
[19:15] <niemeyer> hazmat did a nice spike for us to start understanding the concept pre-UDS
[19:15] <niemeyer> This is about the spikje
[19:15] <niemeyer> spike
[19:15] <niemeyer> The feature will come after the repository is working
[19:16] <kim0> Is there any discussion about combining the actions from two different formulas
[19:16] <kim0> For example .. if I'd like to run a wordpress cluster
[19:16] <niemeyer> kim0: In which sense?
[19:16] <hazmat> yeah.. that was an experiment against local repository directories not against the remote repo that will be the future of formula sharing in ensemble
[19:17] <kim0> they'd have to share files over some shared storage
[19:17] <kim0> like nfs or gluster ..etc
[19:17] <kim0> that would probably be a different formula
[19:17] <niemeyer> kim0: Just add a relation which describes how to configure such storage
[19:17] <hazmat> niemeyer, its a deploy with scenario
[19:17] <hazmat> the units of wordpress need local access to the shared storage
[19:18] <niemeyer> hazmat: Not necessarily
[19:18] <niemeyer> hazmat: It depends on what the intention is
[19:18] <niemeyer> hazmat: The basic idea of setting up shared storage is doable with a plain relation
[19:18] <kim0> that's running nfs on an external host
[19:18] <kim0> just like we do memcache right
[19:19] <kim0> cool
[19:19] <niemeyer> Yeha
[19:19] <hazmat> niemeyer, in this case and the case of logging we're left with configuring the local components in an unrelated formula (ie munin configuration for basic stats on the unit, requires a munin relation hook on a un related formula, such that it install and setups munin-node).
[19:19] <hazmat> nfs is client/server
[19:19] <niemeyer> hazmat: You're assuming too much in that case
[19:19] <hazmat> perhaps
[19:19] <niemeyer> hazmat: Mounting a filesystem is trivial with a relation
[19:20] <koolhead17> kim0: hazmat i can check monit if needed
[19:20] <kim0> koolhead17: check in which sense
[19:20] <koolhead17> formula :)
[19:21] <kim0> koolhead17: create a formulas for it ..
[19:21] <kim0> yes that would be awesome
[19:21] <kim0> Alright if no one else has any more questions .. that should be all
[19:21] <kim0> thanks niemeyer hazmat koolhead17
[19:21] <kim0> = Meeting end =
[19:21] <niemeyer> kim0: Great meeting, thanks kim0
[19:22] <kim0> most welcome
=== rabuf_ is now known as rabuf

[21:22] <hallyn_afk> should i be able to 'bzr co lp:principia' and get some formulas?  (/me confused)
=== marrusl is now known as marrusl_afk
[21:43] <hallyn_afk> SpamapS: ^
[21:44] <hallyn_afk> i assume i missed an email or whole thread discussing its moving, but, well, where did it go :)
[22:03] <hallyn_afk> principia-tools/scripts/getall also appears broken, but leads to the bzr commands I actually need
[22:14] <hallyn_afk> heh
[22:14] <hallyn_afk> ensemble deploy --repository=~/bzr/principia-tools/formulas mysql
[22:14] <hallyn_afk> [Errno 2] No such file or directory: '/home/serge/~/bzr/principia-tools/formulas
[22:14] <hallyn_afk> cwd, foo!
[22:22] <hallyn_afk> yay, that was kind of fun
=== skrewler_ is now known as skrewler
[23:15] <pvthodson> just have a simple question what are some common ubuntu cloud applications
[23:16] <pvthodson> or in other words why would I use a cloud server of a standard server install
[23:18] <pvthodson> anyone here
=== marrusl_afk is now known as marrusl
[23:43] <obino> pvthodson: I'm not sure I undersood your question. UEC gives you a IaaS
[23:43] <obino> this means that you can have instance over which you can install whatever you want
[23:44] <obino> it gives you flexibility in handling your server and machine requirements
