| cmaloney | Yaym, upgrading to the latest LXC broke my workflow. :) | 15:28 |
|---|---|---|
| rick_h_ | doh | 15:31 |
| cmaloney | No worries. I needed to migtate to LXD anyway | 15:38 |
| cmaloney | but, y'know, not today. :) | 15:38 |
| greg-g | wait, there's lxd now? | 16:19 |
| * greg-g missed something | 16:19 | |
| cmaloney | greg-g: Yeah, that's for user-land lxc containers | 16:21 |
| greg-g | ahhhh | 16:22 |
| jcastro | I can't go back to old-school lxc anymore | 16:31 |
| jcastro | I didn't even know people still used old lxc | 16:31 |
| jcastro | heh | 16:31 |
| rick_h_ | I still miss the bind to my home dir in lxd | 16:31 |
| rick_h_ | that was the killer feature that I can't get past | 16:31 |
| cmaloney | yeah, some of us still have "legacy" | 16:31 |
| jcastro | yeah, it'd be nice to do a convenience thing like how vagrant does it | 16:32 |
| rick_h_ | though it was fun to launch 40 lxd containers with 4 models of realtime-syslog-analytics at once yesterday | 16:32 |
| jcastro | pas a --developer or something | 16:32 |
| cmaloney | Strangely, I added the stable ppa and upgraded and things are back to normal | 16:32 |
| jrwren | rick_h_: you can still bind homedir with lxd. | 16:32 |
| jcastro | cmaloney: the thing is old lxc was so confusing to me that I prefered to not use it | 16:32 |
| rick_h_ | jrwren: ? I couldn't find a way to do that? | 16:32 |
| jcastro | it's like, doing simple things required reading the man page | 16:32 |
| jcastro | now it's all super simple and the commands make sense | 16:33 |
| cmaloney | jcastro: If I could get lxd to run without bitching then I'd switch to it | 16:33 |
| jcastro | 16.04? | 16:33 |
| rick_h_ | jrwren: there was stuff about how mounting the home dir wasn't allowed as part of preventing security issues/etc | 16:33 |
| cmaloney | 14.04 | 16:33 |
| jcastro | oh, well you can just do it whenever you upgrade? | 16:33 |
| jrwren | rick_h_: yes, it requires a privilged container, which is what lxc was using before. I'll link you to a script. | 16:33 |
| jrwren | rick_h_: i've done it. lots of yellow team is doing it. | 16:33 |
| jcastro | because tbh, if you're using lxd you also should use zfs, it changed my life | 16:33 |
| cmaloney | jcastro: Right, and I'll make that change later. :) | 16:34 |
| jrwren | +1 lxd on ZFS is a must. | 16:34 |
| jcastro | like, real measurable minutes per deployment that adds up to real efficiency gains | 16:34 |
| jrwren | even if it is a ZFS that is on a loopback file. its still excellent. | 16:34 |
| jcastro | and that's just for one person | 16:34 |
| rick_h_ | jcastro: jrwren do you use zfs on it's own device? | 16:34 |
| rick_h_ | yea, I just use that loopback atm | 16:34 |
| jcastro | if your team is using it you're literally saving money | 16:34 |
| jrwren | rick_h_: I have machines on both. | 16:34 |
| jcastro | rick_h_: yeah, one HDD, one SSD for caching | 16:34 |
| jrwren | rick_h_: ZFS on LVM thinpool too | 16:35 |
| cmaloney | jcastro: We're just now working on Ansible deployments, so baby-steps | 16:35 |
| jcastro | loopback is a nice workaround but it prefers dedicated disks | 16:35 |
| * cmaloney braces for the OMGWTFBBQ | 16:35 | |
| jcastro | because I might as well take advantage of snapshotting etc. for other things | 16:35 |
| jcastro | what I do on all new installs now is install, then I make a new zfs pool with a dedicated disk, I call it "home" | 16:36 |
| jcastro | which then gets automounted as /home | 16:36 |
| jcastro | then recreate my user dir, chown it, blammo, zfs for home directory | 16:36 |
| jcastro | tell zfs and docker to use the zfs backends, done. | 16:36 |
| jcastro | less than 2 seconds for each new instance of an OS | 16:37 |
| jrwren | rick_h_: https://github.com/bac/yellow-tools/blob/master/lxd-launch | 16:37 |
| rick_h_ | jrwren: ty | 16:37 |
| jrwren | rick_h_: the tricks are -c security.privileged=true and lxc config device add $name home disk source=$HOME path=/home/$user | 16:37 |
| rick_h_ | jrwren: gotcha | 16:37 |
| cmaloney | See, this is the ubuntu-us-mi channel I love: make an off-handed comment and get multiple ways on how to make things better. :) | 16:38 |
| jcastro | lol | 16:38 |
| jcastro | without a doubt lxd with zfs is probably one of the top 5 things this decade that has literally changed my professional life | 16:38 |
| cmaloney | brb - lunch | 16:38 |
| jcastro | it's up there with "SSDs" | 16:38 |
| jcastro | and "3 monitors" | 16:38 |
| jrwren | ha! | 16:39 |
| jrwren | now if only charms weren't such a pain, eh jcastro ? /zing | 16:39 |
| * jrwren ducks | 16:39 | |
| jcastro | yeah but that's your fault jay | 16:39 |
| jrwren | lol. | 16:39 |
| jcastro | I'll never need KVM or virtualbox ever again | 16:40 |
| jcastro | there's just no escape, <2 seconds to an instance is just too brutally awesome. | 16:40 |
| jcastro | and I don't mean like, 2 seconds, then wait to do stuff | 16:41 |
| jcastro | I mean 2 seconds counting going into the new instance | 16:41 |
| jrwren | or less. | 16:41 |
| jcastro | "But wait, most of that is typing the exec command to go into the container". | 16:41 |
| jcastro | yes. | 16:41 |
| jrwren | surely on that new BEAST of a server you got its less than 500ms. | 16:41 |
| jrwren | I feel like it is well under 2s on my ancient home server. | 16:42 |
| jcastro | it's a beast, but it's old | 16:42 |
| jcastro | so it's like, 2010 ear | 16:42 |
| jrwren | oh! | 16:42 |
| jcastro | but it's about 3 seconds | 16:42 |
| jrwren | how are you timing? I want to check mine. | 16:42 |
| jcastro | on a modern machine, with an NVM-E SSD? sheeeeeeeeet. | 16:42 |
| jcastro | time lxc launch ubuntu:16.04 | 16:43 |
| jrwren | watch mine take minutes because it refreshes the image. | 16:43 |
| jrwren | hahaha,,, yup... retreiving image. | 16:43 |
| jcastro | yeah, it just means you haven't used that image in 10+ days | 16:43 |
| jrwren | yup. | 16:43 |
| jcastro | also, I totally forgot some bash shell things that are useful | 16:44 |
| jcastro | lxc delete juju-whatever-[1..10] will kill 10 orphaned containers | 16:45 |
| jcastro | oh, you'll need a --force on that one | 16:45 |
| jrwren | even fetching the image it launched in 40s. second launch took 4.47s | 16:46 |
| jrwren | I guess i'm not as impatient as I thought. | 16:47 |
| jcastro | yeah, for one offs 2 secs vs. 5 is no big deal | 16:47 |
| jcastro | it's when you're like "hey coworker wants you to test this 15 node monster" when it really pays off | 16:47 |
| jrwren | ya know what bugs me??? juju uses destroy. lxc uses delete. snap uses remove. ALL TO DO CONCEPTUALLY THE SAME THING!!! | 16:49 |
| * jrwren rages | 16:49 | |
| jcastro | I know | 16:49 |
| jcastro | I find myself `juju list`ing alot | 16:50 |
| jcastro | which comes from `lxc list` | 16:50 |
| jrwren | oh yeah. | 16:50 |
| jcastro | to be fair, snaps ootb learned from juju's evolution though | 16:50 |
| jcastro | `snap login` is exactly the same as juju's login thing | 16:51 |
| jcastro | they both 2FA the same too | 16:51 |
| jrwren | yup, lots of good stuff. | 16:52 |
| cmaloney | Hey, as soon as LXC does WIndows I'll ditch Virtualbox. :) | 17:29 |
