=== freeflying_away is now known as freeflying === thumper-afk is now known as thumper === CyberJacob|Away is now known as CyberJacob [08:03] InformatiQ: Glad you found the vars. FWIW, I included an example of cat'ing the vars yaml file in the paste at line 53: http://paste.ubuntu.com/6442336/ [08:05] InformatiQ: and thanks for the pointer about the key names in ansible, I'll update that in charm helpers too. [08:25] can we change config flag with juju set dynamically? [08:25] like set quantum's ext network pool [08:39] freeflying: running `juju set servicename mysetting=foo` will trigger the config-changed hook on all units of servicename in addition to providing the new value for the mysetting config optin (which must be part of the config.yaml). [09:06] noodles775, sounds cool, thx === axw_ is now known as axw [09:54] good morning/day/whateveryoutimeis [09:55] is there any page which lists who is using juju? [09:56] I usually don't see juju much in the devops circles (which is where juju should be really) [09:56] so I was hoping to get a feeling of the adoption of juju [09:57] also if anyone here does juju consulting I would interested to have a quick chat [09:58] Hi InformatiQ. I'm not aware of a page listing adoption, jcastro is the person to talk to I'd think (when he's awake). [09:58] Hi noodles775 [10:00] noodles775: so in ansible if i need to open a port i just run the command in shell from ansible [10:00] right? [10:02] InformatiQ: Normally if it's to expose the service, you'd use `juju expose servicename`... is that what you're after? eg, https://juju.ubuntu.com/docs/charms-exposing.html [10:09] noodles775: i thought you had to put open anyway === freeflying is now known as freeflying_away [10:15] InformatiQ: yes, sorry. I'm not sure of the best way to do that with ansible - perhaps a command is the best way. [10:15] * noodles775 checks [10:18] Yeah, there's a charm-helper for it (charmhelpers.core.hookenv.open_port), but it's just trivially calling open-port. [10:22] jamespage: Thanks for landing the one-liner yesterday. I've got another branch here which deals with an issue InformatiQ pointed out yesterday - but I'm assuming I shouldn't be pinging you for each branch. Are there a bunch of people subscribed or reviewing? [10:22] Anyway, fwiw: https://code.launchpad.net/~michael.nelson/charm-helpers/no-hyphens-in-ansible-yaml-keys/+merge/195931 [10:26] noodles775, I'll do it for future review credit :-) [10:26] jamespage: Done :-) (although, can we go by line-count? :P) [10:29] noodles775, reviewed and merged - thanks [10:29] Great, thank-you! [10:32] noodles775 jamespage : so everytime i make a charm using ansible i copy the charmhelpers tree in my hooks? [10:32] InformatiQ, for now yes [10:33] there are plans to release charm-helpers (at least the stable, core ones) for 14.04 [10:33] + PPA's for backports (I expect) [10:33] 14.04 that's a long wait [10:36] i need to get familiar with launchpad [10:37] InformatiQ: Based on our experience yesterday, I'm putting together a charm-bootstrap-ansible branch on github that'll make it easier (it uses a script to just pull in or update the parts of charmhelpers you need) [10:38] noodles775: oh great thanks noodles [10:39] i am more familiar with github [10:44] I'm trying to work out the best place to initialize some storage shared between units in my service (a Swift container) [10:45] I'm trying to work out the best place to initialize some storage shared between units in my service (a Swift container) [10:45] The problem I see is that if I do it in my install or config-changed hook, then every unit will attempt to intialize it. [10:46] If I do it in my peer relation-joined hook, then it is only initialized if there are more than one unit. [10:51] stub: it shouldn't matter I think? (that is, the PUT request for container creation is idempotent - http://docs.openstack.org/api/openstack-object-storage/1.0/content/create-container.html ) [10:51] stub: you just get a 202 instead of a 201 [10:52] I guess that isn't the real problem [10:52] Ah - or you want to do more than just create the container... [10:52] Yeah. [10:53] If there is a single unit, the unit needs to use the container. If there are multiple units, only the master unit needs to use the container. [10:53] If I 'deploy --units=3', then until the peer relation hooks are run I'll have 3 units that don't know about each other and will all attempt to use the shared storage. [10:54] Hrm, that seems to make sense though (that until they know about each other, they assume they use the shared storage themselves). [10:55] yeah. Also, if I add a new unit I don't want it to crap all over the shared area when it thinks it is alone. [10:55] I think I need some sort of locking, but I don't think I can do that with Swift? [10:56] create_container_if_not_exists_else_fail [10:57] You should be able to do that with multiple requests? (ie. a HEAD for metadata, which will 404 if it doesn't exist) [10:57] Maybe append a UUID to the container name... [10:57] Ah - right, but that'll just race. [10:58] stub why not the first container writes a lock file to the container (assuming the container is a filesystem of some sort) [10:58] That master-election thing someone mentioned on the mailing list would be useful here (that doesn't eist) [10:59] InformatiQ: Swift is an object store, and some of its features make locking problematic I think [11:00] jamespage, fwiw I've resubmitted the multiple floating pools branch. I see the mp to nova-compute is still outstanding, do you have any philosophical objection to that one or is it just in the queue ? [11:00] (lake of consistency, for example, http://julien.danjou.info/blog/2012/openstack-swift-consistency-analysis ) [11:02] gnuoy, in the queue but uds this week [11:02] ok, understood [11:02] gnuoy, was that the one that does the mtu setting stuff? [11:02] I was pondering that approach [11:02] jamespage, thats the one [11:03] jamespage, what's your reservation about the approach ? [11:04] gnuoy, well as much as possible I'm adverse to twiddling network knobs and configuration in the charm [11:05] I think that should be done during provisioning and written into /etc/network/interfaces [11:08] jamespage, really ? Surely a customers experience would be far better if they deploy openstack via stock maas and twiddle the mtu setting afterwards. If you do object strongly I can add it to my MaaS hacking instead [11:08] gnuoy, that's kinda why I'm still pondering it [11:09] jamespage, I can see your pov, there is an element of compensating for a missing MaaS feature [11:11] gnuoy, yes indeed [11:12] * jamespage thinks a bit more [11:39] hello juju!

[11:46] ashipika, I would suspect that the bootstrap node is still being installed; but you would need to see which node is allocated in the maas ui and go check to be sure [11:47] its possible something bad happened... [11:48] jamespage: thanks for your reply. yes. something strange is going on with my maas.. seems to be installing, but the node just shutsdown when it is "done" [11:48] ashipika, maas nodes have to be registered and commissioned prior to use; the commissioning step does what you just described above [11:49] and that's triggered when you accept the nodes in MAAS [11:49] yes.. but the status on the web says: Allocated to [11:49] i already went through the commisioning step and accepting and whatnot [11:51] ashipika, probably worth asking in #maas - more knowledge in that channel as this sounds maas-ish [11:51] thanks!

[12:59] jamespage@armstrong:~/src/charms/precise$ charm get ceph [12:59] Error: ceph not found in charm store. [12:59] ouch! [12:59] marcoceppi, ^^ [13:30] jamespage: what. [13:31] marcoceppi, that was my reaction as well [13:32] marcoceppi, https://code.launchpad.net/~charmers/ [13:32] what the hell [13:32] marcoceppi, I suspect " Registered by Curtis Hovey 17 hours ago " is the cause [13:33] sinzui, ^^ [13:33] https://launchpad.net/charms/trusty === exekias_ is now known as exekias [13:49] jamespage, marcoceppi egad. I don't think registering trusty is the exact cause because I registered bundles several months ago [13:50] jamespage: I just changed trusty to experimental to de-empahise it [13:52] mthaddon, ^^ can you shed light on this issue? [13:52] jamespage, mthaddon: With projects, you explicitly set the series that is the focus of development. [13:53] sinzui, charms is a distributed tho [13:53] so I expect it behaves differently [13:53] jamespage, I did register trusty yesterday as I did bundles a few months ago. I did not edit precise [13:54] precise is set as supported, and once in that state, I can only become "current stable release" and "obsolete" [13:54] trusty is experimental [13:58] * mthaddon catches up [13:59] mthaddon, jamespage: I was mistaken. /charms/trusty was NOT experimental. It claimed to be active development like precise. I just changed it to be Experimental after flipping between staging.lp and lp [13:59] ah, yeah, it's now working for me, so I'm glad something was changed [14:00] jamespage: I would definitely recommend lp:charms/precise/ceph though [14:00] I'm not. I did make the change and I really didn't expect this. And I really don't know if I have fixed anything [14:02] I think if it was set to active development it's entirely expected [14:06] jamespage, have I fixed it? I ran "bzr branch lp:charms/ceph ceph" and got a branch [14:07] I think so yes [14:08] okay I see this command did change the listing [14:08] charm search ganglia [14:09] damn. ppetraki was the first to spot the problem and I didn't understand the issue when we talked about it [14:14] oh that [14:25] jamespage: another short charmhelpers branch for an error which the tests only highlight when run in isolation :/ https://code.launchpad.net/~michael.nelson/charm-helpers/missing-import-for-ansible-helpers/+merge/195967 [15:15] Problems using containers created using juju | http://askubuntu.com/q/379902 [15:15] sinzui: could you jump in to uds-servercloud-1 ? [15:16] * sinzui does, first killing cpu intensive procs [15:18] sinzui: https://plus.google.com/hangouts/_/72cpjufj5oc8omdro2acjh1vco?authuser=0&hl=en [15:29] all right, now I need to get my head around how relations work in juju! [15:29] my mind boggles [15:32] so in the metadata, you can set the requires stuff. I'm not sure why for instance you might need to specify "database:\n interface: mysql." Why the database part, when we already know that mysql is a db [15:33] does the interface specify the port? [15:33] or is it something different entirely? [16:46] hmmmm [16:46] I think I'm beginning to undestand relations, but at what point does one end of the relationship set their variables, such as ip address, etc? [16:46] or am I doing things wrong? [16:48] SuperMatt: so you can set relation data at anytime [16:49] but it won't be sent until the hook finishes executing [16:51] basically, I have a reverse proxy, and I want to get the ip address from one of the web servers. how and where would I set the ip address? In the start section? [16:53] SuperMatt: so your charm is providing the http interface, or is it consuming the interface [16:53] err, "requires" [16:53] well I have two charms, one for the web server, one for the reverse proxy [16:54] and I just want to update the reverse proxy with the ip addresses of the web servers [16:54] SuperMatt: right, so what you should have is the web server providing the http interface, and the reverse proxy requring the http interface [16:54] yes [16:55] SuperMatt: so the http interface relation on the app needs to [16:55] relation-set hostname=unit-get private-address port= [16:55] SuperMatt: and the proxy http interface relation needs to [16:55] relation-get hostname [16:55] relation-get port [16:55] inside of the hook, so that it can read those values [16:55] ok [16:55] so which hook? the relation-changed hook? [16:56] SuperMatt: it'd be easier to explain if you provided a paste of each of the metadata.yaml files [16:56] SuperMatt: then I could provide exact hooknames that it would happen in [16:56] http://paste.ubuntu-helpouts.org/9 [16:57] http://paste.ubuntu-helpouts.org/10 [16:57] the second is a modified version of the node-app we talked about yesterday [16:58] SuperMatt: okay, so on the nginx-hash site, you're going to have a hook called reverseproxy-relation-changed [16:59] got it [16:59] I assume that's where I do my magic to update nginx [16:59] SuperMatt: each relation has four events/hooks tied to them relation-joined, relation-changed, relation-departed, and relation-broken [16:59] sure [16:59] SuperMatt: yes, you'll also want to add a realtion-departed/broken hook logic to remove those values from nginx config as the relation no longer exists [16:59] makes sense [16:59] SuperMatt: we have an nginx-reverseproxy charm, if you want to use as a reference [17:00] I might check it out [17:00] I had to make my own anyway, because I had to compile in an extra plugin [17:00] SuperMatt: nevermind, we don't have a reverseproxy charm [17:00] hahaha [17:00] could have sworn we did [17:01] well I have a general idea of how to update the conf file [17:01] * marcoceppi may have confused with squid [17:01] the only thing I need is the list of IPs from the node-apps [17:01] SuperMatt: you can do that with relation-list actually [17:01] oh? [17:01] SuperMatt: so if you wanted to rebuild the file everytime [17:01] you could have the reverseproxy-relation-changed run relation-list to get a list of all the units [17:02] SuperMatt: then loop through those units and do a relation-get to that unit [17:02] * marcoceppi finds example [17:02] lemme show you what I have [17:03] http://paste.ubuntu-helpouts.org/11 [17:03] that's not by any means complete [17:03] SuperMatt: that's pretty much the idea [17:03] sure [17:04] but ip isn't set anywhere [17:04] I need to look up the relation-get syntax for specifying a unit [17:04] SuperMatt: you want to use hostname [17:04] http interface exposes `hostname` rather than ip [17:04] right [17:04] is hostname something that's set automatically by the unit? [17:05] marcoceppi, jcastro can someone give me the hangout for the gui vUDS now please [17:05] SuperMatt: no, it's something that the relation requries authors to set [17:05] happening now I mean [17:05] gary_poster, I just made the same mistake, check the time [17:05] it's lunch [17:05] SuperMatt: the assumption is all service will provide you with a port and a hostname [17:05] it just doesn't have a "lunch" session there [17:05] jcastro, oh! ok thanks [17:05] marcoceppi: ok, I'm beginning to understand [17:06] so when does the service set that? [17:06] relation-changed? [17:06] SuperMatt: relation-changed is the best time to do this [17:06] http://paste.ubuntu.com/6449144/ [17:06] ok [17:06] I think I get you [17:07] SuperMatt: since you're re-creating the file each time, you could symlink relation-departed and relation-broken to this file and then it'll update whenever a unit goes away [17:07] and that's your logic for updating when units get removed [17:07] I'm trying to ssh a unit in local environment and I get http://paste.ubuntu.com/6449146/ any suggestions? [17:07] but the thing I don't understand is, if both ends are running relation-changed at the same time, how does the reverse proxy know when the node has prepared all variables? [17:07] vds: don't use sudo [17:08] vds: only use sudo when you're bootstrapping and destroying a local environment [17:08] SuperMatt: they arent' running at the same time [17:08] oh [17:08] ok [17:08] I just assumed they were [17:08] SuperMatt: -changed will be run anytime there is a new data on the relation wire [17:08] marcoceppi, I'll try thanks [17:08] ok [17:08] I'll just give it a bash now [17:09] I think I have everything I need [17:09] SuperMatt: so what happens is, you add-relation and the -joined then -changed event will fire for each unit attached. Then if any of those two hooks added data -changed will be fired for the other side, -changed continues to fire on each side until there is no more new data being sent [17:10] I see [17:10] well fingers crossed, here goes nothing [17:13] marcoceppi, if I try to juju deploy without sudo I get http://paste.ubuntu.com/6449178/ [17:17] marcoceppi: your help has been indispensible throughout my trails and tribulations. For that, I thank you. [17:17] vds: something is wrong then [17:17] vds: destroy-environment, then make sure you .juju folder is recursively owned by you [17:18] then bootstrap/deploy again [17:18] marcoceppi, same result [17:19] vds: what version of juju? [17:19] vds: this is really a bug, you shouldn't be using sudo for commands other than bootstrap and destroy-env [17:19] marcoceppi, 1.13.2-raring-amd64 [17:20] vds: try upgrading to the latest, 1.16.3 and trying again [17:20] let's see what happens... === cmagina is now known as cmagina-lunch [19:30] jcastro: I was told you're the man to talk to about juju [19:30] :) === cmagina-lunch is now known as cmagina [20:18] InformatiQ, shoot! [20:18] I am ready! [20:18] BANG! [20:18] * thumper ducks [20:19] jcastro: well i was wondering about the adoption of juju, like who is using it, what environments, own charms vs cs [20:19] we're still in the early stages [20:20] we really didn't hit a production quality release until ~6 months ago [20:20] and for some people needing HA is still an issue which we'll address in 14.04 [20:20] but we use it in production and we have customers who do [20:20] Juju hasn't been included in an LTS yet so the adoption is still early-stages [20:21] who is your target customers profiles? [20:22] So right now the obvious one is anyone deploying and orchestrating on openstack [20:22] However I am not a product-ish guy, so right now I'm focused on developers and sysadmins [20:22] well amazon fits in quite well too [20:22] I don't have like a list of personas or anything we target offhand [20:23] oh yeah, amazon, hp cloud, and azure are all first class citizens [20:23] well i am just trying to understand where juju is going [20:23] it's just openstack has a bunch of deployment painpoints that we address nicely [20:23] oh so did you see the 2.0 roadmap video from today's UDS? [20:23] so developers write juju code and sysadmin run the juju infra? [20:24] haven't seen the video yet [20:25] well the idea is to bridge dev and ops [20:26] for example being able to deploy something when developing it in a way that is similar to how you would run it in production [20:27] ah you meant you care about them as your target users, ok [20:27] got that point [20:27] https://www.youtube.com/watch?v=ZjzImjEinB8&feature=c4-overview&list=UUyT3AcQaRx_yl1yYLa5ikXQ [20:27] is the video [20:27] oh for sure. [20:27] well yeah that is my day job, do ops and get devs involved [20:27] right, so the idea with dev charms in particular [20:28] like rails, or the django charm [20:28] is that a developer will straight away be deploying to instances [20:28] and he iterates in a way that can be deployed by ops [20:29] I made a joke once, "You ever deploy something from a developer where he hardcoded in `localhost`? That's what we're trying to fix." [20:29] so the local provider the guy is developing on uses the same cloud images you would use on say Amazon [20:30] and he can rev at his pace on his laptop, and then when he's ready redeploy it to AWS [20:30] or over to your internal hardware [20:30] we want to make it easy for people to shift workloads around in different clouds [20:30] yup, and make dev envs as colse as possible to prod [20:31] which might make a case for mking a juju local provider run on virtualbox for those devs using macs [20:31] but anyway [20:32] coming from a sysadmin and ansible background [20:33] the playbook is a living thing, it changes as your conf changes so next time you dpeloy it it is uptodate and configured) [20:33] while that doesn't seem like the workflow in juju [20:33] i know you can always fork and edit the charm [20:33] just was wondering what is the official view on that? [21:16] is anyone else using it with MAAS and having the issue where juju locks up because the maas api is throwing back "not authorized" errors? === CyberJacob is now known as CyberJacob|Away === CyberJacob|Away is now known as CyberJacob [21:55] InformatiQ, I think a charm is flexible to accomodate a dynamic playboook. It may be analogous to a git hub project branch that a charm pulls from (at any deploy that git branch could be updated, if not pinned).
