| nk121 | anyone around? trying to merge to cloud-init files and not having any luck | 04:45 |
|---|---|---|
| nk121 | the file /var/lib/cloud/instances/INSTANCE_ID/cloud.cfg only shows the first file, and i can see both files in user-data.txt | 04:46 |
| === harlowja is now known as harlowja_away | ||
| nk121 | n/m its working now | 05:36 |
| nk121 | well, working more, its combining the two files, but its replacing sections, not combining | 05:43 |
| nk121 | this doc http://cloudinit.readthedocs.org/en/latest/topics/merging.html seems to imply the new way should combine | 05:43 |
| nk121 | and it gives an exact example of what i'm looking for -- combinging run_cmds | 05:44 |
| nk121 | i tried the merge_how from comment #4 from https://bugs.launchpad.net/cloud-init/+bug/1316323 | 05:57 |
| nk121 | but same thing | 05:57 |
| nk121 | my run_cmd section is not merging | 05:57 |
| nk121 | merge_how: "dict(allow_delete,recurse_array)+list(recurse_array,append)" | 06:05 |
| nk121 | shouldn't that list(recurse_array,append) do the trick? | 06:05 |
| zilberstein | harlowja_away, I specified timezone as the following: | 10:43 |
| zilberstein | timezone: UTC | 10:43 |
| zilberstein | doesnt work | 10:43 |
| zilberstein | I specified timezone in /etc/cloud/cloud.cfg | 10:43 |
| zilberstein | but it was not set | 10:43 |
| zilberstein | so why that bloody cloud-init do not set timezone ?! | 12:50 |
| Odd_Bloke | zilberstein: Is there anything in /var/log/cloud-init.log to suggest the problem? | 12:54 |
| zilberstein | Odd_Bloke, nothing related to timezone | 12:57 |
| zilberstein | that's the thing ! | 12:57 |
| zilberstein | it silently ignores timezone ! | 12:57 |
| Odd_Bloke | zilberstein: How are you checking what timezone is set? (And what distro are you on?) | 12:58 |
| zilberstein | cat /etc/sysconfig/clock, redhat | 12:58 |
| zilberstein | 6 | 12:58 |
| zilberstein | also /etc/localtime | 12:58 |
| Odd_Bloke | zilberstein: Is timezone in one of the module lists in cloud.cfg? | 13:01 |
| smoser | zilberstein, the timezone module only runs once per instance. | 13:04 |
| smoser | so booting, then changing /etc/cloud/cloud.cfg to have it, will not result in a reboot causing any change. | 13:04 |
| smoser | you'd need to specify user-data to affect it. or either | 13:05 |
| smoser | a.) rm /var/lib/cloud/instance/sem/config_timezone && reboot | 13:05 |
| smoser | b.) sudo cloud-init single --frequency=always --name=timezone | 13:06 |
| smoser | c.) give user-data (or a part of multipart user-data) including: | 13:06 |
| smoser | #cloud-config | 13:06 |
| smoser | timezone: UTC | 13:06 |
| smoser | d.) capture the image, and then deploy it again (which changes the instance-id, which makes that "per-instance" module run again). | 13:07 |
| smoser | also, as Odd_Bloke said, you have to make sure that the module is enabled in /etc/cloud/cloud.cfg | 13:08 |
| smoser | i'm not 100% certain that cloud-init timezone works for rhel, but what it looks like it intends to do is | 13:11 |
| smoser | delete /etc/localtime | 13:11 |
| smoser | symlink /etc/localtime -> /usr/share/zoneinfo/UTC | 13:12 |
| smoser | now, if /usr/share/zoneinfo/UTC did not exist, it log an exception 'Invalid timezone' | 13:13 |
| smoser | zilberstein, ^ | 13:13 |
| zilberstein | smoser, I know. Timezone was configured before instance started | 13:24 |
| smoser | zilberstein, cloud-init will configure it (i think correctly), but only does that once per instance. cloud-init is about initialization, not runtime sytem configuration. | 13:25 |
| zilberstein | smoser, I thought cloud-init should remove /etc/localtime and create new symlink on its own | 13:25 |
| smoser | well, it does. | 13:25 |
| smoser | once per instance. | 13:25 |
| smoser | launch an instance with the user-data (in 'c' above) and see if you get what you want. or do 'a'. i think it will. | 13:26 |

| nk121 | good morning friends | 17:21 |
| nk121 | i'm having trouble merginging to cloud init configurations | 17:21 |
| nk121 | i don't understand the merge syntax | 17:22 |
| nk121 | its not combining my runcmd and write_files sections, but instead overriding them in the second file | 17:22 |
| harmw | smoser: whats that ubuntu version and branch for cirros-dev again? | 17:34 |
| smoser | https://code.launchpad.net/cirros | 17:37 |
| harmw | sry, u meant the updated buildroot for ubuntu 14.04 (?) :) | 17:37 |
| harmw | *I meant | 17:37 |
| smoser | ah | 17:38 |
| smoser | https://code.launchpad.net/~smoser/cirros/buildroot-upgrade | 17:38 |
| harmw | cool | 17:38 |
| nk121 | smoser: any tips on how to debug merges? | 17:39 |
| harlowja | nk121 eck, damn merging :( | 17:41 |
| nk121 | :( | 17:41 |
| harlowja | haha | 17:41 |
| harlowja | i sorta created it, unleashed it on the world, lol | 17:41 |
| nk121 | thanks :) | 17:41 |
| harlowja | ^ for better or worse, ha | 17:41 |
| harlowja | ha | 17:41 |
| nk121 | i feel i'm trying to do something simple, just combine two files, no overwriting | 17:42 |
| nk121 | actually q1- is there a way to re-run the merge without launching a new instance? (i figured out how to re-run cloud init on a box, but thats after the merge step) | 17:42 |
| nk121 | q2- the docs seem to imply the defaults for the new merge style is what i'm looking for, but i don't see that being the case | 17:43 |
| harlowja | hmmm, i don't think so; pretty sure the merging happens to early | 17:43 |
| harlowja | let me see if i can make a way for u to try this merge stuff without having to boot instances all the time | 17:43 |
| nk121 | if i don't have any merge_how sections, should the default do what i'm expecting? | 17:44 |
| nk121 | which is, combine the two runcmd and write_files sections from two cloud init files | 17:44 |
| nk121 | not overwrite or replace | 17:44 |
| nk121 | (i'm running on trusty using the ec2 default image) | 17:45 |
| harlowja | one way to find out :-P | 17:45 |
| nk121 | well so far, does not seem to :P | 17:45 |
| harlowja | :) | 17:47 |
| harlowja | nk121 ok, so http://paste.ubuntu.com/10671425/ that should make it easier for u to mess around | 17:55 |
| harlowja | if u just run that on a vm with cloud-init; u can adjust that and see what the final result is... | 17:55 |
| harmw | smoser: I noticed some nice fbsd specific additions on LP | 17:55 |
| nk121 | harlowja: ok, i'll give it a shot | 17:56 |
| harlowja | for example http://paste.ubuntu.com/10671436/ might be what u want | 17:57 |
| harlowja | that comes up with | 17:57 |
| harlowja | Merged result: | 17:57 |
| harlowja | {'a': 'b', 'c': [1, 2, 3, 4]} | 17:57 |
| harlowja | ^ list appends | 17:57 |
| harlowja | if u feel like it, keep track of a little readme doc about this while u are learning, could be useful docs for others | 17:57 |
| harlowja | since i know its not so obvious... | 17:58 |
| nk121 | harlowja: sure, if i figure this out, i'll write up what i did and how to debug it | 17:59 |
| harlowja | thx; feel free to mutate the above script; probably useful for others to | 17:59 |
| harlowja | mutate/own/whatever lol | 17:59 |
| harlowja | maybe mutate not best word :-P | 17:59 |
| nk121 | i follow ya | 18:00 |
| nk121 | wow, its so much faster to develop when you can re-run locally =-] | 18:06 |
| nk121 | and your second paste lead me to the solution | 18:06 |
| nk121 | i only had the merge_how section in the first file | 18:06 |
| nk121 | that seems to not be whats described in Specifying multiple types and its effect in http://cloudinit.readthedocs.org/en/latest/topics/merging.html | 18:07 |
| nk121 | or maybe i'm just not parsing that right | 18:09 |
| nk121 | (the doc text) | 18:09 |
| harlowja | ya, u probably don't need it in certain ones, but how it works is that the current payload defines the merge_how ; which will then be used with the prior already merged/whatever yaml | 18:12 |
| harlowja | it doesn't really retain what was the 'last' | 18:12 |
| harlowja | although it could i suppose, just doesn't currently | 18:12 |
| nk121 | i think that doc page could use a working example, and an explanation of the merge options | 18:13 |
| harlowja | sure | 18:13 |
| harlowja | http://bazaar.launchpad.net/~cloud-init-dev/cloud-init/trunk/view/head:/doc/merging.rst | 18:13 |
| harlowja | commits welcome ;) | 18:13 |
| harlowja | or any adjustments u feel appropriate | 18:13 |
| nk121 | ok i've added it to my list, i'll give it a shot after i get this milestone completed | 18:14 |
| harlowja | cools | 18:14 |
| nk121 | but regardless, you've got me unstuck, and i really appreciate that | 18:14 |
| harlowja | np | 18:15 |
| harlowja | here to serve! | 18:15 |
