| harmw | ill have a look, thanks | 08:35 |
|---|---|---|
| harmw | hm, annoying | 09:13 |
| harmw | thre is a wrapper to figure what/how to start udhcpc, and then a default.script gets run to actually -do- stuff | 09:14 |
| harmw | hm, it would be sexy if udhcpc could use the wrapper script itself as a default.script, to keep everything in 1 place (in case we want to add support for another option sometime in the future) | 09:26 |
| harmw | uhm, that quilt thing isn't able to patch busybox - atleast it doesn't look like it | 09:48 |
| harmw | smoser: https://code.launchpad.net/~harmw/cirros/udhcpc-wrapper | 11:26 |
| fifthecho | Has anyone used fpm to build cloud-init? | 12:47 |
| fifthecho | Because I'm trying to build current cloud-init packages for older distros (Debian 6, Centos 5) to use on a CloudStack cloud and it's proving quite frustrating. | 12:51 |
| smoser | fifthecho, no. i dont know fpm. if you're interested in pursuing that, patches to make it work would be accepted. | 13:07 |
| smoser | also, there is ./packages/brpm | 13:07 |
| smoser | but maybe you knew that | 13:07 |
| === alexpilotti_ is now known as alexpilotti | ||
| fifthecho | Or, is there some repo out there for cloud-init 0.7.5 for older distros? | 13:35 |
| smoser | what is not functional for older distros? just deps ? | 13:41 |
| harmw | fifthecho: is there a sane reason to start supporting centos 5 these days? | 13:42 |
| harmw | given 7 is out | 13:43 |
| smoser | harmw, so i would have just patched the string 'udhcpc' to invoke udhcpc.cirros instead of udhcpc. | 13:43 |
| fifthecho | smoser: Older distros have older packages that don't have the CloudStack provider. | 13:43 |
| smoser | as you have it i think it is a bit recursive | 13:43 |
| fifthecho | smoser: Unfortunately we have customers who are stuck on old releases. | 13:43 |
| smoser | fifthecho, right. but why does 0.7.5 not work on older distros. that was the question. | 13:44 |
| fifthecho | smoser: It should, but there's no packages I can find and I'm having difficulties building RPMs and DEBs as there's no real instructions on how cloud-init builds their packages. | 13:44 |
| smoser | harmw, ie, i was just oging to do this: http://paste.ubuntu.com/7904991/ | 13:45 |
| smoser | fifthecho, ah. so i'd start either with trunk, using ./packages/brpm | 13:45 |
| smoser | or updating something in epel or something. | 13:45 |
| harmw | well, we could've just move /sbin/udhcpc to somewhere else and replace it with the wrapper :p | 13:46 |
| smoser | correct. | 13:48 |
| smoser | but i didnt want to do that. | 13:48 |
| smoser | because then /sbin/udchpc would be the wrapper | 13:48 |
| harmw | btw your patch keeps feeding udhcpc.cirros with options, wich is not needed anymore either | 13:48 |
| harmw | yea | 13:48 |
| smoser | so then when a user invoked udhcpc "manually", they'd get our wrapper. and the wrapper wouldn't know if it was invoked via ifupdown or "upser" | 13:49 |
| smoser | s/upser/user/ | 13:49 |
| harmw | uhu | 13:49 |
| smoser | so yeah, if you want you can copy the stanza there | 13:49 |
| smoser | we can set the options to "" | 13:49 |
| harmw | well, if were going to patch busybox anyway I'd opt for adding my patch and keep it nice&tidy | 13:50 |
| harmw | instead of ultimatly defacing udhcpc :p | 13:50 |
| harmw | (in ifupdown.c that is) | 13:50 |
| smoser | thats fine. | 13:50 |
| smoser | but call udhcpc, not 'ifupdown' | 13:50 |
| smoser | because calling 'ifupdown' is going to call udchpc | 13:51 |
| smoser | which is going to call ifupdwon | 13:51 |
| harmw | I dont think I'm following that one, my patch adds a call to /sbin/ifupdown for busybox to execute - that script in turn runs udhcpc, which is calling the same script yet again though with the renew|bound|whatever args | 13:53 |
| smoser | harmw, you added a entry to ext_dhcp_clients which is part of FEATURE_IFUPDOWN_EXTERNAL_DHCPC | 13:57 |
| smoser | i had assumed that what that means is that when the user types: | 13:58 |
| smoser | ifup | 13:58 |
| smoser | and the network is ocnfigured for dhcp | 13:58 |
| smoser | that 'ifup' would then call udhcp (in the current path) | 13:58 |
| smoser | and instead, your patch is making it call | 13:58 |
| smoser | ifupdown up | 13:58 |
| smoser | which i assumed was basically the same as calling ifup | 13:59 |
| smoser | which would then run that code again ... | 13:59 |
| harmw | ah like that, deadlocking | 13:59 |
| smoser | right. thats how i read it. i could be wrong. | 14:00 |
| smoser | how does it select an entry to run ? | 14:00 |
| harmw | either way, there is no ifupdown binary currently - so that atleast shouldn't hurt | 14:01 |
| harmw | it tries each entry | 14:01 |
| smoser | ah. based on executable_exists | 14:01 |
| harmw | indeed | 14:01 |
| harmw | which is why I just prepended my code to the struct | 14:01 |
| smoser | ah. ok. so now it makes more sense. i'd leave more of it intact though. | 14:02 |
| smoser | but you were right in your assesement, that we could just replace /sbin/udhcpc (other than we'd be changing the behavior of that binary by wrapping it) | 14:03 |
| smoser | harmw, thank you for humoring me. | 14:04 |
| harmw | humoring? realy | 14:04 |
| smoser | now i understand much more of your patch | 14:06 |
| smoser | and it makes a fair amount of sense. | 14:06 |
| smoser | other than i dont like the name "ifupdown" | 14:06 |
| harmw | but... | 14:06 |
| smoser | cirros-dhcp ? | 14:07 |
| harmw | +c | 14:07 |
| harmw | or: cirros-dhclient | 14:07 |
| harmw | anyway | 14:07 |
| harmw | Ill think of something | 14:07 |
| smoser | yeah. | 14:07 |
| harmw | you read the commitmsg btw? | 14:07 |
| smoser | :) | 14:08 |
| smoser | no. | 14:08 |
| smoser | sorry. | 14:08 |
| harmw | lol | 14:08 |
| smoser | maybe that would have saved all this, eh? | 14:08 |
| harmw | only one way to find out | 14:08 |
| smoser | what about the '-h hostname' -i vendor -I client -l leastime stuff ? | 14:08 |
| smoser | is that useful to us ? | 14:09 |
| harmw | havent given that a thought just yet | 14:09 |
| smoser | i'd think hostname probably is | 14:09 |
| harmw | my focus was on putting something out there to aid in future enahncements | 14:09 |
| harmw | to be able to add things like hostname, indeed | 14:09 |
| smoser | and have no idea what: [[ -h %hostname%]] | 14:10 |
| smoser | means | 14:10 |
| harmw | (which is quite sane, for areas without clouds) | 14:10 |
| harmw | *environments | 14:10 |
| harmw | anyway, my commitmsg contains a note about beeing able to apply the patch to busybox :p | 14:11 |
| harmw | which is why I asked if you read it, realy | 14:11 |
| harmw | :) | 14:11 |

| harmw | haha, not looking into the obvious :p | 19:04 |
| harmw | oh no wait, my trouble was with busybox | 19:09 |
| harmw | hm, lets see | 19:09 |
| aneto | Hello, I am currently having trouble trying to get mounts to work in EC2 with cloud-init 0.7.4 installed from repl my config and logs are https://gist.github.com/anthony-neto/1c522c14ef286646cc9a I having being trying to use a bashton AMI that has a working cloud-init as an example but its a old version of cloud-init, I am going crazy | 19:10 |
| aneto | If anyone in here is using cloud-init in ec2 with centos, and could gist my a mininmal config to test the mounts I would appreciate it =) | 19:16 |
| === zz_gondoi is now known as gondoi | ||
| smoser | aneto, so what is that ? | 19:42 |
| smoser | you want to test mounts. how? | 19:42 |
| aneto | that gist is what I have been trying, including the log from cloud init, I just want to see cloud-init mount the ephemeral mounts ec2 assigns. | 19:43 |
| aneto | I have gotten userdata to work, but for the life of me cannot get the swap or ephemeral mounts to work | 19:44 |
| aneto | I see this in the log, Attempting to determine the real name of ephemeral0 | Mapped metadata name ephemeral0 to /dev/sda2 | did not find entry for sda2 in /sys/block | Ignoring nonexistant default named mount ephemeral0 | 19:54 |
| aneto | smoser, I just want to get the default mounts working for ephemeral0 and swap | 20:06 |
| smoser | well, built in "should" work. | 20:08 |
| smoser | it should behave properly with no additional config. | 20:08 |
| aneto | smoser, if cloud-init doesn't find an entry in /sys/block it ignores the mount? | 21:01 |
| smoser | i think it does. | 21:02 |
| smoser | maybe you can say "put it there nayway" | 21:02 |
| smoser | well, no. it says: | 21:03 |
| smoser | http://bazaar.launchpad.net/~cloud-init-dev/cloud-init/trunk/view/head:/doc/examples/cloud-config.txt | 21:03 |
| smoser | line 185 | 21:03 |
| smoser | but i think for 'ephemeral0' it has to exist | 21:03 |
| smoser | and swap too probably | 21:03 |
| aneto | hmm has this always been the case? I installed an older version of cloud-init and got the mounts to work, however the /sys/block looks exactly the same as the problematic ami | 21:05 |
| smoser | i dont know . i dont remember to have changed it. | 21:05 |
