| zero_shane | hi all - relatively new to cloud-init, but I haven't been able to find an answer to this yet ... does cloud-init support setting variables which can be used subsequently in templates - example FOO=bar, then within a template {{FOO}} for expansion ? I'd want to apply this in cloud.cfg, allowing me to set more generic/templatized templates, that can be tweaked based on the base cloud.cfg information | 00:28 |
|---|---|---|
| smoser | harlowja_, coul dyou merge with trunk? | 00:52 |
| smoser | there is one conflict in debian.py | 00:53 |
| smoser | harlowja_, and if you are around... | 01:09 |
| smoser | harlowja_, i merged for yhou. | 04:22 |
| smoser | all-in | 04:23 |
| smoser | and uploaded to yakkety | 04:23 |
| smoser | so you better not have messed it up! | 04:23 |

| coolshiva123 | hi team | 10:54 |
| coolshiva123 | need a help with cloud-init on centos | 10:54 |
| coolshiva123 | anyone there? | 11:00 |
| Odd_Bloke | coolshiva123: Ask your question, and if anyone knows the answer then they might respond. :) | 11:05 |
| coolshiva123 | I have a centos7 template and i have some scripts in per-boot | 11:28 |
| coolshiva123 | the cloud-init fails to execute them | 11:28 |
| coolshiva123 | i have a clean cloud-init.log | 11:28 |
| coolshiva123 | and cloud-init-output.log | 11:28 |
| coolshiva123 | anyway to troubleshoot why cloudinit ignores script in per boot? | 11:28 |
| smoser | coolshiva123, are they executable ? | 11:58 |
| smoser | you should be able to run | 11:59 |
| smoser | sudo cloud-init single --name=scripts-per-boot --frequency=always | 11:59 |
| smoser | and with '--debug' you'll get mroe output to screen. | 11:59 |
| coolshiva123 | hi | 12:17 |
| coolshiva123 | these scripts are definitley executable | 12:18 |
| coolshiva123 | [root@bceglc298 per-boot]# cloud-init single --name scripts-per-boot --frequency always --debug usage: cloud-init [-h] [--version] [--file FILES] [--debug] [--force] {init,modules,query,single} ... cloud-init: error: unrecognized arguments: --debug | 13:06 |
| smoser | coolshiva123, --debug has to go to cloud-init not to 'single' | 15:43 |

| harlowja_ | smoser thx boss | 16:49 |
| harlowja_ | i was gonna merge today, but i guess u did | 16:49 |
| smoser | yeah, i fixed that. | 16:49 |
| smoser | pylint and six is obnoxious | 16:49 |
| harlowja_ | lol | 16:49 |
| smoser | pylint --errors-only is really helpful | 16:49 |
| smoser | but six really tricks it out | 16:49 |
| smoser | on curtin we run --errors-only and it catches so many things | 16:49 |
| harlowja_ | cool | 16:49 |
| smoser | but here it has a bunch of false positives | 16:50 |
| smoser | maybe 12 | 16:50 |
| harlowja_ | smoser i was thinking, do u still want daemon support in cloud-init ? something that uses pyudev for example to get notified of hardware changes and activates modules? | 16:50 |
| harlowja_ | that was a cloud-init 2.0 thing, but doesn't seem so hard to do it ... | 16:50 |
| smoser | so.. | 16:51 |
| smoser | plans for cloud-init in near term. | 16:51 |
| smoser | a.) get 0.7.8 release that works for network configuration on centos on NoCloud and ConfigDrive | 16:51 |
| smoser | b.) get to git | 16:51 |
| smoser | c.) support getting network configuration from network'd datasources | 16:52 |
| harlowja_ | k | 16:52 |
| smoser | ie, in he OpenstackMetadata | 16:52 |
| smoser | so tha'td mean in the local stage, we'd bring up networking for the localnet and check 169.254.169.254 | 16:52 |
| smoser | and then say "oh look, my networking!" | 16:53 |
| harlowja_ | smoser u might also want to comment on https://review.openstack.org/#/c/324054/ | 16:53 |
| harlowja_ | i'll eventually start a openstack-dev ML about that if it doesn't move | 16:53 |
| harlowja_ | its sorta whacky to say 'the bug is there, and we aren't gonna change it, to bad...' | 16:53 |
| smoser | its not really a bug | 17:00 |
| smoser | just stupid | 17:00 |
| harlowja_ | :-p | 17:00 |
| smoser | chaing the format of an opaque string is not breaking abi | 17:00 |
| harlowja_ | agreed | 17:00 |
| smoser | it would seem like a change in EC2 from : | 17:01 |
| smoser | i-abcdefg | 17:01 |
| smoser | to | 17:01 |
| smoser | i-abcdefgh | 17:01 |
| harlowja_ | omg | 17:01 |
| harlowja_ | how dare u | 17:01 |
| harlowja_ | lol | 17:01 |
| smoser | (ie, they realized at some point that 6 chars was not enough) | 17:01 |
| smoser | this is actually true | 17:01 |
| harlowja_ | nice | 17:01 |
| harlowja_ | lol | 17:01 |
| smoser | and it actually *did* break things (stupid things) | 17:01 |
| harlowja_ | stupid things be stupid | 17:01 |
| smoser | that assumed 8 chars (or whatever it was) was how long that thing should be | 17:01 |
| smoser | all that MP is doing is replacing the internal (host) interface name | 17:02 |
| smoser | with another interface name, right? | 17:02 |
| smoser | as long as it keeps the value as consistent as the previous value (not changing on reboot, or stop/start) then it would surely seem fine to me | 17:02 |
| harlowja_ | ya, seems fair to me | 17:09 |
| harlowja_ | smoser comment on that review :-P | 17:11 |
| smoser | on it | 17:11 |
| smoser | harlowja_, how do i review ? | 17:14 |
| harlowja_ | press 'A' | 17:14 |
| smoser | i'm logged in... but i dont see a text area or anhyting | 17:14 |
| harlowja_ | ya, the GUI changed | 17:14 |
| harlowja_ | lowercase 'a' | 17:15 |
| smoser | man. | 17:15 |
| smoser | that is *worse* than it used to be! | 17:15 |
| smoser | which is pretty technically impressive | 17:15 |
| harlowja_ | def | 17:15 |
| harlowja_ | no disagreements from me, it got weirder | 17:15 |
| sather | I'm trying to play around with cloud-init modules. I want to write a simple handler that takes the user-data passed in an EC2 instance and writes it to a yaml file. | 20:52 |
| sather | what datatype is _cfg? | 20:53 |
| sather | in the handle function `def handle(name, _cfg, _cloud, log, _args):` | 20:54 |
| harlowja_ | sather i believe its just a dict | 21:01 |
| harlowja_ | cloud is just a http://bazaar.launchpad.net/~cloud-init-dev/cloud-init/trunk/view/head:/cloudinit/cloud.py#L43 object | 21:02 |
| harlowja_ | and args are i forget, lol | 21:02 |
| harlowja_ | where'd the amazon guy go | 21:52 |
| harlowja_ | damn, we lost him already :( | 21:52 |
| sather | harlowja_: thanks | 22:06 |
| smemsh | smoser: i see you maintain cloud-init for ubuntu. surprisingly, in ubuntu-14 cloud images, network config via cloud-init (0.7.5) does not work because "ifup: failed to open lockfile /run/network/ifstate.lo: No such file or directory" during first boot. is this worth filing a bug or never get looked at due to age of release? | 22:40 |
| smemsh | smoser: or maybe it's packaging error for cloud images and should not go to cloud-init package? | 22:41 |
| sather | could someone help me understand this error: | 22:44 |
| sather | __init__.py[WARNING]: Unhandled no | 22:44 |
| sather | n-multipart (text/x-not-multipart) | 22:44 |
| sather | realized I should be using write_files module | 23:00 |
| smemsh | the snippet in cloud-init-container.conf that does mkdir -p /run/network needs to also be done for non-containers or ifup --all fails | 23:09 |
| smemsh | it runs _bring_up_interface() before network-interface.conf / network.conf have run apparently, which fails on ubuntu | 23:15 |
| smemsh | due to mk /run/network | 23:15 |
| smemsh | no | 23:15 |
| smemsh | i'll bet the tests do not try static ip setup, only dhcp and that probably works | 23:17 |
| smemsh | yeah, i can see, init-local banner, then ifup --all fails, then cloud-init-nonet runs (which blocks waiting for static), and finally static networking comes up, which is the one that does the mkdir -p. so it happens too late, it can never work | 23:30 |
| smemsh | how do i inject runcmd in there to mkdir -p? network comes from metadata, it looks like it runs before anything from user-data | 23:33 |
| sather | grr...boss says we can't use write_files directive | 23:58 |
| sather | because we need to not touch the metadata file | 23:58 |
| sather | :( | 23:58 |
