| [07:54] <Sonia_> Hi , need help in cloud-init ? | |
| [08:01] <kwadronaut> Sonia_: please state your question and stick around. | |
| [08:02] <kwadronaut> formulating your question often already helps understanding the problem | |
| [08:02] <kwadronaut> and people are not always behind their keyboards, so asking for the question, doesn't mean people stick around until it is there. | |

| [09:57] <Sonia_> sorry , yesterday I put my question and got no response till today morning, hence realized if there is no one in the chat , and if time is out , question gets deleted | |
| [09:58] <Sonia_> my question on cloud-init is , how we can re-run cloud-init without rebooting the VM .....and in the same process give another user-data to it. (not the one initially executed by cloud-init) | |
| [10:02] <kwadronaut> ah i see it now if i scroll up...., you could add any local data in /var/lib/cloud/? | |
| [10:09] <Sonia_> I was doing following steps to re-run cloud-init : | |
| [10:10] <Sonia_> 1. rm -rf /var/lib/cloud/insance* | |
| [10:10] <Sonia_> 2. run cloud-init init , cloud-init modules --mode init/config/final | |
| [10:10] <Sonia_> these will run it with the same user-data which I supplied at the time of VM provisioning | |
| [10:28] <Sonia_> but in between if I try to give my own, doenst work | |
| [10:53] <harmw> you could also fetch the userdata using curl, just to make sure it got updated properly on the infra-side (beeit openstack or whatever platform you're running) | |
| [11:48] <Sonia_> I used config-drive here ,and user-data gets to the VM successfully and gets executed. | |
| [11:48] <Sonia_> when i re-run cloud-init , it again gets the user-data from config-drive | |

| [12:47] <kwadronaut> i see a typo in your rm -rf, a t has gone missing in the instance | |
| [12:48] <kwadronaut> well, if you want to use different data/source, that needs to be changed too of course? | |
| === zz_gondoi is now known as gondoi | |
| [13:43] <smoser> Sonia_, you can use 'ci-tool' as a friendly-ish way to "seed" data. | |
| [13:44] <smoser> http://bazaar.launchpad.net/~smoser/cloud-init/ci-tool/view/head:/ci-tool | |
| [13:44] <smoser> it also has 'reset' which will clean out the state in /var/lib/cloud | |
| [13:45] <smoser> Sonia_, also, if you're just wanting to quickly iterate on testing things... lxc can provide a really nice way to do that. | |
| [13:45] <smoser> http://bazaar.launchpad.net/~smoser/cloud-init/ci-tool/view/head:/ci-tool | |
| [13:45] <smoser> oops. | |

| [14:14] <Sonia_> thanks smoser for the link , I will certainly look at the tool | |
| [14:14] <Sonia_> my use case is that , initially coud-init will work with user-data supplied during provisioning time | |
| [14:15] <Sonia_> just that at later point of time , want to re-run cloud-init without rebooting the VM with a different user-data script. | |
| [14:15] <Sonia_> kwadronaut , sorry for the typo in the chat , during testing , 't' is there | |
| [14:16] <smoser> Sonia_, why do you want to do that ? | |
| [14:16] <smoser> ci-tool would help you accomplish it, but curious. | |
| [14:16] <Sonia_> kwadronaut , so if I want a different data source after the VM is provisioned, can I change it later point of time ? | |
| [14:17] <Sonia_> well , I dont want VM to do all the initial configurations .....running them again may wipe out many settings done | |
| [14:19] <Sonia_> smoser , shouldnt these steps work too ? | |
| [14:20] <Sonia_> 1. clean out /var/lib/cloud 2. run cloud-init init 3. replace the user-data script with out own in the instance/ directory 4. run cloud-init modules --mode init/config/final | |
| [14:21] <smoser> no. it probably wont work. | |
| [14:21] <smoser> i'm sorry, i can't really help now. | |
| [14:21] <Sonia_> no problem , I will try ci-tool | |
| [14:23] <Sonia_> smoser , is there a way to change the data source also ? | |
| [14:24] <smoser> sure. its configurable. | |
| [14:24] <smoser> in ubuntu 'dpkg-reconfigure cloud-init' | |
| [14:25] <smoser> dpkg-reconfigure or ci-toolw ill adjust etc/cloud/cloud.cfg.d/90_dpkg.cfg | |
| [14:27] <Sonia_> ok , I am on RHEL | |
| [14:30] <Sonia_> hope I can still change the configurations. | |
| [16:57] <kwadronaut> smoser: awwww. that lxc link is promising! | |
| [16:58] <smoser> kwadronaut, yeah, its nice. | |
| [16:58] <smoser> on ubuntu, you can also snapshot quickly with btrfs (or lvm if you wanted). | |
| [16:58] <smoser> the big feature really was the "clone hook" to allow you to pass in user-data on the clone rather than create. | |

| [18:27] <sauce> smoser you the man | |
| [18:27] <smoser> thanks | |
| [18:27] <smoser> :) | |
| [20:24] <Sonia_> smoser , I may need help with ci-tool | |
| [20:26] <Sonia_> so first i ran ci-tool reset , which removed instance and instances/ directory for me. | |
| [20:45] <Sonia_> post that , I am trying to seed data using the command , "ci-tool seed -s nocloud /opt/my-user-data" | |
| [20:56] <Sonia_> then I run cloud init again by "ci-tool run" | |
| [20:57] <Sonia_> correcting my earlier command : "ci-tool seed /opt/SJuser-data" | |
| [20:57] <Sonia_> running ci-tool again doesnt execute the new user-data file , any mistake I am doing here in using the tool ? | |
