| tmckay | woohoo, ^^ looks like good reading | 14:40 |

| *** bjarne_ has joined #openstack-sahara | 15:10 | |
| bjarne_ | few general questions re creating a new hadoop cluster using Sahara: after creating an instance using Nova, how does sahara execute cmds on the instance? setup ssh keys and run cmds using ssh? | 15:20 |
| bjarne_ | and how does sahara connect to the new instance? over public floating IP? | 15:21 |
| bjarne_ | does sahara need admin role to be able to call nova,neutron etc apis? | 15:24 |
| *** hdd has quit IRC | 15:59 | |
| elmiko | bjarne_: couple of answers | 16:19 |
| elmiko | bjarne_: sahara uses ssh to communicate with the instances of its clusters | 16:19 |
| elmiko | as for the ip addressing, you have the option of using floating ip or static | 16:19 |
| elmiko | sahara does need an admin role to run some of its commands to the other services | 16:19 |
| elmiko | bjarne_: there are more options for connecting to instances but it is probably best to check the documentation for more information | 16:20 |
| elmiko | http://docs.openstack.org/developer/sahara/userdoc/configuration.guide.html | 16:20 |
| elmiko | and | 16:21 |
| elmiko | http://docs.openstack.org/developer/sahara/userdoc/advanced.configuration.guide.html | 16:21 |
| elmiko | bjarne_: as for instance creation, you can use heat or the direct engine(which will be deprecated in liberty) | 16:22 |
| elmiko | well, sahara will use heat or direct | 16:22 |
| *** hdd has joined #openstack-sahara | 16:22 | |
| elmiko | tmckay: ping | 16:45 |
| tmckay | hi | 16:45 |
| elmiko | so, you think the spec needs examples for both sahara and barbican configs? | 16:45 |
| elmiko | i mean, it's mostly just a single line change | 16:46 |
| tmckay | elmiko, I think it seemed strange to me because what is shown is the default. So you normally wouldn't set it. | 16:47 |
| tmckay | not a big deal, though | 16:47 |
| tmckay | just a suggestion | 16:47 |
| elmiko | ok, so maybe just show the barbican example? | 16:47 |
| tmckay | or maybe use that format from the sample configs, where we show the param with #? I don't know. Trouble with the barbican one is that it's not final yet :) | 16:48 |
| elmiko | right, plus i figured it might make sense to show how it will appear normally | 16:49 |
| elmiko | where normally == default =) | 16:49 |
| tmckay | ok, that's fine. It is only a spec after all :) | 16:50 |
| elmiko | yea, i didn't want to define too | 16:51 |
| elmiko | i'll clearly mark that example as the default though | 16:51 |
| tmckay | ok | 16:52 |
| elmiko | thanks for the comments though =) | 16:52 |
| tmckay | np | 16:54 |
| bjarne_ | elmiko: thanks for taking the time to answer | 16:59 |
| elmiko | bjarne_: np, hope it helps =) | 17:00 |
| bjarne_ | yes, this helps. floating IPs is not an option for me, so I'd have to access instances through a relay machine or custom network namespace | 17:01 |
| bjarne_ | for ssh connectivity from sahara server to instances | 17:03 |
| elmiko | if you turn floating ips off, and are using neutron, the instances will still get fixed ips on a private network | 17:03 |
| elmiko | but yea, there are multiple options for allowing sahara to reach the cluster nodes | 17:04 |
| bjarne_ | yes .. I'd turn off floating ip | 17:04 |
| bjarne_ | just to confirm: if I turn off floating ip and use neutron, then I have to setup a relay machine or custom network namespace for sahara server to be able to connect to instances? | 17:11 |
| elmiko | no, you should be able to turn off floating ip and sahara will use the private network supplied to neutron for connection | 17:11 |
| bjarne_ | that's the part I don't get .. does it mean sahara server and instances are in the same private network? | 17:12 |
| elmiko | sorta, | 17:13 |
| bjarne_ | ;-) | 17:13 |
| elmiko | when creating a cluster you will need to supply a private network for the instances to attach on | 17:13 |
| elmiko | sahara will use this network, through a virtual router to communicate with the nodes | 17:13 |
| elmiko | the floating ip option provides a mechanism for operators to create a "public" network that can also attach the instances | 17:14 |
| elmiko | look at the last paragraph in http://docs.openstack.org/developer/sahara/userdoc/configuration.guide.html#floating-ip-management | 17:14 |
| bjarne_ | ok | 17:14 |
| elmiko | it's kinda confusing, but we provide multiple options to help provide operators the most flexibility with their configurations | 17:15 |
| bjarne_ | last paragraph is about Policy configuration | 17:17 |
| elmiko | oh, i meant in that section. just before the "Notifications configuration" | 17:18 |
| bjarne_ | k | 17:18 |
| elmiko | it's more or less what we were just discussing | 17:19 |
| bjarne_ | yes, thanks a lot elmiko. what part of the code should I look for details re network setup during cluster setup? | 17:23 |
| bjarne_ | like create the private network and virtual router | 17:24 |
| elmiko | hmm, let me see if i can find a link | 17:25 |
| elmiko | https://github.com/openstack/sahara/blob/master/sahara/service/networks.py | 17:26 |
| elmiko | i think that's the actual module that does some of the assignment | 17:26 |
| elmiko | but you will also want to look at the direct and heat engine classes to see how the cluster is provisioned | 17:27 |
| elmiko | https://github.com/openstack/sahara/blob/master/sahara/service/heat/heat_engine.py | 17:27 |
| elmiko | i think if you follow those pieces of code around you will see some of this interaction | 17:28 |
| elmiko | bjarne_: i gotta run out for a few, good luck! | 17:30 |
| bjarne_ | thanks much, elmiko | 17:31 |
