| [13:28] <realnorth_> anyone here have a link or know what environment variables I can feed juju? | |
| [13:28] <realnorth_> also is it possible to choose which server to add a charm to? | |
| === realnorth_ is now known as realnorth | |
| [13:31] <melmoth> realnorth, i have been told that jitsu has a -deploy-to option | |
| [13:31] <melmoth> but i never try it yet | |
| [13:33] <smoser> i'm guessing just about everyone is sleeping, lifeless and bigjools at least. allenap maybe around? | |
| [13:33] <smoser> i hadnt' followed all the dns thread | |
| [13:33] <allenap> smoser: Hi there, what's up? | |
| [13:33] <smoser> but i thought that lifeless suggested doing ec2 like names, which i think is generally useful. | |
| [13:34] <smoser> but then others didn't like that because of "no human friendly hostname" | |
| [13:34] <smoser> wouldn't cnames fix that? | |
| [13:34] <smoser> and having dhcp hand out the hostname as the human-friendly-cname? | |
| [13:34] <allenap> smoser: Yes. One of the questions I had was: what do names with the IP address in add beyond just using IP addresses? | |
| [13:35] <allenap> rvba: ^ maybe you can help too? | |
| [13:35] <smoser> not much i guess. | |
| [13:35] <smoser> but if you add in the cname, then you have both, dont you? | |
| [13:35] <allenap> Yeah. | |
| [13:36] <allenap> For smaller clouds, having a nice name is more useful. For massive clouds it's a burden. | |
| [13:37] <smoser> random bit of info . i think that there was some dns service that just converted "v.x.y.z.somedomain.com' to v.x.y.z Ip address for you | |
| [13:37] <smoser> i tihnk ii think you'd just allow it as configurable. | |
| [13:37] <smoser> an dif someone sets the "hostname " for something then they get it. | |
| [13:38] <smoser> who cares. | |
| [13:38] <rvba> smoser: so a node would have an ec2 like name and a "human" CNAME then? | |
| [13:38] <smoser> yeah. | |
| [13:38] <smoser> well, that was my thought. | |
| [13:38] <smoser> reverse looking up its IP would get the ec2-like name | |
| [13:38] <smoser> but who cares. | |
| [13:38] <rvba> right | |
| [13:39] <rvba> The main problem with writing DNS config files is with reverse config files (because of the classful/classless pb) so yeah, that sounds like something we should definitely look into. | |
| [13:39] <smoser> if you allow the api to set the hostname of a node, then someone can easily take a DB that has "MAC:preferred-hostname" and populate maas from that. | |
| [13:40] <rvba> allenap: actually, we sort of mentioned that on the call this morning: having "two" hostnames: the ec2 like one and the manual one. | |
| [13:40] <rvba> But we thought about that on the DB level. As smoser said, CNAME is exactly that at the DNS level. | |
| [13:41] <allenap> Yeah. We also mooted allowing nodes to specify their preferred hostname in the DHCP request and making that a CNAME of the "ugly" name. | |
| [13:42] <allenap> But that doesn't cope with collisions well. | |
| [13:42] <smoser> well, its easily fixable anyway. | |
| [13:42] <smoser> the only place that that has value is when maas is not running the dhcp/dns server | |
| [13:43] <smoser> and it assumes that something gave this system a relevant IP address based on its mac address. | |
| [13:43] <smoser> er.. relavant hostname based on mac | |
| [13:43] <smoser> and whatever that something is can then be just dumped/queried. and a tool then update the node once its in maas. | |
| [13:44] <rvba> allenap: collisions are not really a problem if we can write the reverse zone files using only ec2 hostnames. | |
| [13:44] <smoser> collisions are an issue if maas isn't serving the dhcp | |
| [13:44] <rvba> allenap: for each zone, we compute the superset classful network and we write the full reverse zone file for that with ec2-like names. | |
| [13:44] <allenap> rvba: I mean collisions of the "nice" names if done by dhcp; two nodes could ask for the same thing. | |
| [13:45] <rvba> Right, that's another problem. I was thinking about the clasless network collision. | |
| [13:45] <rvba> Maybe the term "collision" is not really proper for that. | |
| [13:45] <allenap> I think my brain has had enough of that stuff for this week ;) | |
| [13:59] <rvba> smoser: that's a great idea I think. Maybe there is something I'm missing but it definitely looks like the missing piece of the puzzle. | |
| [14:23] <roaksoax> allenap: howdy :) so I was looking at your recen changes and was wondeirng, wher's that maas-provision binary? | |
| [14:25] <rvba> smoser: I tried to summarize why I think your idea is great in the email I just sent. We would have the full forward/reverse DNS config written using ec2-like names. Then on top of that we could use nsupdate to add CNAME record to accommodate custom hostnames. | |
| [14:25] <rvba> records* | |
| [14:25] <smoser> rvba, thanks. | |
| [14:25] <smoser> we expose "friendly-hostname" setting in maas via api | |
| [14:25] <smoser> right? | |
| [14:26] <rvba> Yes we do. | |
| [14:26] <smoser> so my 'mac-addr:friendly-hostname' population script is easy. | |
| [14:27] <smoser> (ie, it takes a file full of lines with 'mac-addr friendly-hostname' and just iterates over it calling maas and setting the hostname for each node based on mac | |
| [14:27] <smoser> ) | |
| [14:27] <allenap> roaksoax: It's a front-end for several commands. It will probably evolve into the front-end for all of MAAS (so that we no longer expose twistd or django-admin). | |
| [14:27] <rvba> smoser: yes, that would work. | |
| [14:28] <roaksoax> allenap: right, but where is it? do we need a wrapper for it (like we did with maas binary)? (see debian/extras/maas in packaging branch) | |
| [14:28] <rvba> smoser: hum, the key we use in the api is the system_id. | |
| [14:28] <roaksoax> rvba: that is indeed a good idea as I was mentioning to smoser | |
| [14:28] <roaksoax> but that means that servers wont have <rack>.<city>.<blahblah>.domain.com | |
| [14:28] <roaksoax> which might come handy | |
| [14:29] <roaksoax> when you do inventory | |
| [14:29] <roaksoax> that's why I think we should consult this with sysadmins | |
| [14:29] <rvba> Well, we might provide a way to set the custom hostname based on tags. | |
| [14:29] <rvba> So that would be possible. | |
| [14:30] <smoser> rvba, somehow i can surely get a node by its mac-id, no? | |
| [14:30] <rvba> Let me check. | |
| [14:30] <smoser> err.. get a system_id by its mac_id. | |
| [14:30] <roaksoax> rvba: right, there's various possiblities to approach the issues yes | |
| [14:30] <roaksoax> we need to consider invetory from now on | |
| [14:30] <roaksoax> and we need to consider Administrators, and Datacenters and the standards they use | |
| [14:30] <roaksoax> and provide a sokution based on that | |
| [14:31] <roaksoax> we can't simply impose them something we believe is better when they already follow standards | |
| [14:31] <rvba> smoser: no, system_id is the key really. But that's something we could add very easily. | |
| [14:33] <smoser> rvba, well i think its essential, really. | |
| [14:33] <rvba> smoser: I completely agree. | |
| [14:33] <rvba> smoser: please file a bug. | |
| [14:34] <rvba> smoser: that's something really easy to add. | |
| [14:34] <rvba> The mac is the information that the outside world knows so it makes sense. | |
| [14:35] <roaksoax> allenap: btw is that part of the maas cli? | |
| [14:37] <allenap> roaksoax: It is, and it will need a wrapper. It's very simple though: python -m provisioningserver | |
| [14:39] <roaksoax> allenap: right, and what is the maas-cli stuff | |
| [14:39] <roaksoax> allenap: err apiclient | |
| [14:39] <allenap> roaksoax: Don't know :-/ | |
| [14:43] <roaksoax> ok :) | |
| [16:17] <roaksoax> rvba: ping | |
| [16:17] <roaksoax> rvba: do you how how could you effectively run yui tests? | |
| [16:20] <rvba> roaksoax: the yui tests are run as part of the test suite but you can run only the yui tests. | |
| [16:20] <roaksoax> rvba: right, I'm looking towards running them in the actual yui3 source package from the archives | |
| [16:20] <roaksoax> rvba: so I was wondering how is it that you run them? | |
| [16:21] <roaksoax> and get the ooutput of them as? | |
| [16:21] <rvba> In MAAS, we use SST to do that (see src/maasserver/tests/test_js.py). | |
