| angelinux | but I get an error when I try to boostrap | 12:59 |
| marcoceppi | angelinux: what is the error? | 13:30 |
| angelinux | @marcoceppi: http://askubuntu.com/questions/859862/juju-bootstrap-on-a-private-openstack-cloud-fails here you can find details | 13:36 |
| angelinux | @marcoceppi: the error is "json: cannot unmarshal string into Go value of type nova.jsonEntity" | 13:37 |
| angelinux | @marcoceppi could you please help me? | 13:37 |
| marcoceppi | angelinux: what's your region name in OpenStack? Is it indeed RegionOne? | 13:42 |

| bdx | lazyPower: ping | 19:17 |
| bdx | interesting issue here | 19:18 |
| bdx | if I `lxc launch:16.04 es-test`, and add the elastic.co gpg key and source repo, update apt, and `sudo apt install elasticsearch`, I get a successfull installation | 19:19 |
| bdx | `lxc launch ubuntu:16.04 es-test`* | 19:20 |
| bdx | whats interesting, is when I mimic these ops with juju -> https://github.com/jamesbeedy/juju-layer-elasticsearch-base | 19:20 |
| bdx | I hit this error http://paste.ubuntu.com/23665305/ | 19:21 |
| bdx | or, even more, if I `juju deploy ubuntu`, and run the same ops to install elasticsearch that I run in the lxd container, I get a failure | 19:22 |
| bdx | with http://paste.ubuntu.com/23665305/ | 19:22 |
| jrwren | bdx: how different is your default lxd profile from your juju lxd profile? | 19:23 |
| bdx | jrwren: http://paste.ubuntu.com/23665326/ | 19:24 |
| jrwren | bdx: now that IS interesting ;) | 19:24 |
| bdx | jrwren: yeah, I'm on the line with others who are experiencing the same thing right now | 19:25 |
| bdx | I'm thinking I should write the list | 19:25 |
| bdx | jrwren: right | 19:26 |
| bdx | jrwren: I'm honestly over trying to troubleshoot this ... over my head at this point | 19:27 |
| jrwren | bdx: i thought mabye you had set security.privileged=true in your default profile or something. | 19:27 |
| bdx | jrwren: yea, that was my initial thought too | 19:28 |
| bdx | jrwren: even if I remove the extra profile, such that my juju container is only left with the default profile applied | 19:28 |
| === Guest73326 is now known as sebastienp | ||
| bdx | I still get the error | 19:29 |
| bdx | so strange | 19:29 |
| jrwren | right, it doesn't seem to be a profile thing. | 19:29 |
| jrwren | bdx: can you pastebin output of `lxc config show <container>` for the two containers? | 19:32 |
| bdx | jrwren: here's the juju deployed container -> http://paste.ubuntu.com/23665355/ | 19:34 |
| bdx | jrwren: here's the straight lxd -> http://paste.ubuntu.com/23665359/ | 19:35 |
| bdx | jrwren: good call | 19:35 |
| bdx | jrwren: how does the juju container end up with all that extra jazz in there? | 19:36 |
| bdx | crazy | 19:36 |
| jrwren | bdx: the lxd provider in juju does it. | 19:36 |
| bdx | ahhh | 19:36 |
| bdx | wow, talk about opinionated | 19:36 |
| jrwren | juju is very opinionated. :) | 19:37 |
| bdx | jrwren: what do you feel is the best approach to resolving the issue I'm experiencing? | 19:38 |
| jrwren | bdx: email the list. | 19:38 |
| bdx | the issue being that elasticsearch won't install to juju deployed lxd containers | 19:38 |
| bdx | right | 19:38 |
| bdx | will do | 19:38 |
| bdx | jrwren: thx | 19:38 |
| jrwren | bdx: i'm going to try to repro. is it possible its 2 diff elastic search packages? | 19:40 |
| bdx | no | 19:44 |
| jrwren | bdx: if it helps at all, I get the couldn't write errors on package installation on my lxc. | 19:44 |
| bdx | jrwren: juju deploy lxc? | 19:45 |
| jrwren | so, I don't think this is a juju issue. | 19:45 |
| bdx | oh really | 19:45 |
| jrwren | no, no juju at all. | 19:45 |
| bdx | I don't get them on straight lxd | 19:45 |
| jrwren | bdx: I'll paste a repro, see if it works for you. | 19:45 |
| bdx | ok | 19:45 |
| jrwren | or rather, see if you do get the error :) | 19:45 |
| jrwren | bdx: https://gist.github.com/jrwren/8b648cc2736e68e82d96334d32b131b9 one file and 2 commands to run. | 19:47 |
| bdx | jrwren: I just got the error on straight lx43 | 19:47 |
| bdx | lxd* | 19:47 |
| jrwren | oops, and I pasted the wrong command. | 19:47 |
| jrwren | bdx: oh, well, ok, that is great! | 19:47 |
| jrwren | bdx: maybe file a bug with elastic.co? | 19:49 |
| bdx | jrwren: I just ran these commands on an fresh xenial aws instance -> http://paste.ubuntu.com/23665448/ | 19:54 |
| bdx | success | 19:54 |
| bdx | jrwren: ^ makes me think its more or less a lxd thing... | 19:55 |
| jrwren | bdx: nice... but still, not working on LXD is bad. | 19:55 |
| jrwren | bdx: I can't imagine it would work in docker, for the same reasons. | 19:55 |
| jrwren | bdx: https://github.com/elastic/elasticsearch/commit/32df032c5944326e351a7910a877d1992563f791 looks like ES fixed it by enabling a parameter, a ES_SKIP_SET_KERNEL_PARAMETERS in the environment. | 20:06 |
| bdx | jrwren: nice find! | 20:08 |
| jrwren | bdx: well, it NEEDS to work in lxd, or else its not a great juju charm :) | 20:08 |
| bdx | right | 20:08 |
| bdx | jrwren: so, is this a use case for a tactic you think? | 20:09 |
| bdx | jrwren: to set ES_SKIP_SET_KERNEL_PARAMETERS prior to the apt install phase | 20:09 |
| bdx | or should I just add the few lines to the reactive file and set the param and then run the install cmds from the layer-apt api | 20:10 |
| jrwren | bdx: I don't know anything about tactics or layers, sorry. | 20:12 |
| bdx | jrwren: now my question is this, we don't want to always skip the kernel params on install, right? so should I detect whether or not the install is happening on a container, and only apply the ES_SKIP_SET_KERNEL_PARAMETERSES_SKIP_SET_KERNEL_PARAMETERS to container installs? | 20:13 |
| bdx | errg .. sorry, that pasted 2ce for some reason | 20:13 |
| jrwren | bdx: yes, that is probably best. | 20:14 |
| bdx | sebastienp:^ | 20:14 |
| bdx | jrwren: thanks for your insight here | 20:14 |
| jrwren | bdx: oh my... have you used that es package? | 20:21 |
| bdx | jrwren: not yet ... I'm trying to though | 20:22 |
| bdx | jrwren: why, whats up with it? | 20:22 |
| jrwren | bdx: well, don't forget to specify openjdk-8-jre-headless package manually. they don't use dependencies. | 20:22 |
| jrwren | bdx: and then, don't be shocked like I was as it allocated 2+GB of ram immediately on starting. NOT virtual. 2.241g of RSS | 20:22 |
| jrwren | i guess that is java magic. | 20:23 |
| bdx | jrwren: openjdk-8-jre-headless installs as a dep of es when you install it from their repo | 20:23 |
| jrwren | bdx: that was not my experience. | 20:23 |
| jrwren | Depends: libc6, adduser, bash | 20:23 |
| jrwren | and on first run, the service fails asking to install a java. | 20:24 |
| bdx | jrwren: yeah ... I'm getting the same thing .... don't know how or why I had success previously (possilby I forgot to add my sources and installed 2.x or something) | 20:32 |
| jrwren | bdx: i see the package in ubuntu archives does have Depends: with a jre. *shrug* no biggie. | 20:33 |
| jrwren | bdx: I was just shocked at the 2.2G memory alloc on start. | 20:34 |
| bdx | jrwren: yeah, thats nuts | 20:38 |
| jrwren | bdx: i wonder what it does on a tiny instance :) | 20:39 |
| bdx | jrwren: whats even worse -> https://docs.mongodb.com/manual/core/wiredtiger/#memory-use | 20:39 |
| jrwren | lol, it had to be mongo | 20:39 |
| bdx | jrwren: I was wondering why my juju controllers were consuming so much ram ... even when barely anything was deployed ... it was driving me crazy, then I found that | 20:40 |
| bdx | lol | 20:40 |
| jrwren | bdx: :( | 20:40 |
| bdx | jrwren: ^ 50%-1G really borks lxd local deploys | 20:40 |
| jrwren | bdx: agreed. I don't leave lxd controllers up for that reason. | 20:40 |
| bdx | if you have a massive lxd-visor, the juju controller will automatically steal all your goods | 20:41 |
| jrwren | bdx: it has gotten MUCH better in jujud itself since some of the 2.0 betas | 20:41 |
| bdx | jrwren: yeah, but the underlying mongo tiger eats up 50%-1G though .... cry cry cry | 20:41 |
| bdx | thats w/o juju memory consumption taken into account of course | 20:42 |
| bdx | something needs to happen about the 50% mem on lxd controllers ... possibly we can apply some mem limit to the juju-controller profile or something | 20:43 |
| jrwren | bdx: painful :( | 20:43 |
| jrwren | bdx: may be as simple as mongoCmd = mongoCmd + "--wiredTigerCacheSizeGB" here: https://github.com/juju/juju/blob/master/mongo/service.go#L185 | 20:48 |
| jrwren | bdx: its wednesday before the holidays and if you are feeling brave, propose that :) | 20:49 |
| petevg | cory_fu, bcsaller: PR for the dump of the logs here: https://github.com/juju-solutions/matrix/pull/56 (It's non ideal for a lot of reasons, but I believe suitable for our basic needs. I'm going to work through some of the TODOs, and prioritize partially based on feedback.) | 21:40 |
| bdx | whats the best way to check if you are in a container or not? | 21:41 |
| bdx | I found this -> https://code.launchpad.net/~zulcss/charm-helpers/is_container | 21:41 |
| bdx | but it isn't in charmhelpers 0.10.0 ... | 21:41 |
| bdx | even more, systemd-virt-check | 21:42 |
| bdx | doesn't seem to even be a thing ... | 21:42 |
| bdx | ahhh, possibly I should be checking the output of 'systemd-detect-virt' | 21:43 |
