The chair is blackboxsw. Information about MeetBot at http://wiki.ubuntu.com/meetingology. 16:08 16:08 Available commands: action commands idea info link nick 16:09 Hi folks and welcome. We've got a big week this week as we are planning on a cloud-init release. So we will have an additional topic in today's agenda 16:09 o/ 16:10 it's been a few weeks, due to holiday schedules/travel, our agenda will be as following: Previous Actions, Recent Changes, In-progress develepment, cloud-init release 18.3 and office hours 16:11 #topic Previous Actions 16:11 last action items are listed in our meeting minutes at the following url: 16:11 #link https://cloud-init.github.io/status-2018-05-29.html#status-2018-05-29 16:12 #ACTION blackboxsw review distro dection and empty modules list [ DONE ] both robjo's branches are landed as of friday of last week. 16:12 * meetingology blackboxsw review distro dection and empty modules list [ DONE ] both robjo's branches are landed as of friday of last week. 16:13 that was a carryover from the meeting before I believe. 16:13 #ACTION blackboxsw carryover network hotplug vs network maintenance on reboot-only 16:13 * meetingology blackboxsw carryover network hotplug vs network maintenance on reboot-only 16:14 I think this was the only other unresolved action. Our team has had mutliple followup discussions internally and with mgerts from Joyent/SmartOs as well 16:14 smoser: and rharper drew up a hackmd doc related to this work here: 16:14 #link https://hackmd.io/NUUO4nndS4CXTItl8Rs6Nw 16:15 We've come to a conclusion on a common near-term approach that will support cold-plug scenarios by allowing datasources to claim whether or not they will re-render networking on a boot event. This would allow cloud-init to react to network metadata changes across boot and enable/disable those devices accordingly 16:16 a WIP branch is available here 16:16 #link expectation is to get the foundation landed this week 16:16 and tracked in trello here 16:16 #link https://trello.com/c/Yp6VG2lP/837-eventpolicy-foundation-for-joyent-and-azure-coldplug 16:17 Note that the metdata ins EC2 is "stale", AFIK, or at least some parts of the data are stale, i.e. they only get refreshed on instance restart 16:17 is it instance restart or "re DHCP" ? 16:17 ie, bounce the interface ? 16:17 #link https://code.launchpad.net/~chad.smith/cloud-init/+git/cloud-init/+ref/feature/maintain-network-on-boot 16:18 robjo: that is correct. 16:18 so a re-read of the metadata on EC2 delivers no/maybe limited new information 16:18 robjo: well, network information is updated. 16:18 user-data is only updatable on stop -> start in ec2 16:18 rharper: AFAIK new metadat gets pick up on instance restart 16:19 ok 16:19 I know the IID also only gets updated on stop-start 16:19 certainly in Azure that's the case. you have to stop the instance before changing attached network interfaces and then bring instance online again 16:20 Yes, in Azure adding network interfaces is not dynamic 16:20 meaning cannot happen while an instance is running 16:21 adding IPs in azure is an online thing, but even azure's network metadata is limited in that it doesn't tell you whether a network interface is static or dynamic. examples here: 16:21 https://hackmd.io/aODzXfa_TOikNtYBLt8erA 16:21 #link https://hackmd.io/aODzXfa_TOikNtYBLt8erA 16:22 Also for Azure there exists the "problem" of accelerated networking, i.e. SR-IOV 16:23 when accelerated networking is on the SR-IOV interface gets the same MAC address as the "Synthetic nic" 16:23 well, they "solved" it by having the kernel auto bond =/ 16:23 the SR-IOV interface gets bound to the synthetic nic in the kernel, that was a patch that went into the kernel 6-9 months ago 16:23 AFAICT, the sriov device just magically comes and goes as it will 16:24 so, one shouldn't worry about the silent bonding ... (I'm being a bit sarcastic here) 16:24 yes, but the interface still shows up, so if output from "ip" command is read one has two devices with the same MAC address, only one of which should be configured 16:25 we ignore any of the mlx4 driver devices 16:25 yes they show up 16:25 OK 16:25 but the directive we got was to ignore them; and DHCP on the netvsc ones 16:25 ...so think that's all I had on action items from previous meeting. 16:26 shall we go to next topic? 16:26 And that of course works until Msft gets a better HW deal from Intel or someone else for their network cards ;) 16:26 heh 16:26 robjo: indeed 16:27 #topic Recent Changes 16:27 due to a couple vacations and some work travel it's been a slightly slower couple weeks below are the cloud-init changes that have gone in: 16:28 - lxd: Delete default network and detach device if lxd-init created them. 16:28 (LP: #1776958) 16:28 - openstack: avoid unneeded metadata probe on non-openstack platforms 16:28 [Chad Smith] (LP: #1776701) 16:28 - stages: fix tracebacks if a module stage is undefined or empty 16:28 [Robert Schweikert] (LP: #1770462) 16:28 - Be more safe on string/bytes when writing multipart user-data to disk. 16:28 Launchpad bug 1776958 in cloud-init "error creating lxdbr0."

Does anyone have any feature pressing that we'd like to get into this release 16:38 estimated release would be Thusday of this week 16:39 I'd whimsically like to include the azure cold-plug stuff, but that means getting those two branches in shape today for a thorough review/test cycle 16:39 s/whimsically/opportunitically/ 16:39 heh I give up 16:42 did we want to pull this in? https://code.launchpad.net/~paul-meyer/cloud-init/+git/cloud-init/+merge/334989 16:45 If there are any pressing bugs or features that need to be in 18.3 we'd like to see them up for review by Wednesday of this week so that we can cut our upstream release. Feel free to send an email to the list cloud-init@lists.launchpad.net or this channel if your branch needs to get some eyes. 16:46 we'll SRU 18.3 then into Xenial, Artful and Bionic after a complete round of testing. 16:46 #topic Office Hours (next ~30 mins) 16:46 :D After 18.3 but before the workshop: https://code.launchpad.net/~rjschwei/cloud-init/+git/cloud-init/+merge/333904 16:47 Folks are around for further discussion on any cloud-init topics of interest 16:47 then maybe at the workshop we can come up with a way to move SLES & openSUSE to sysconfig renderer 16:48 good topic idea 16:48 #ACTION rhaper/blackboxsw review https://code.launchpad.net/~rjschwei/cloud-init/+git/cloud-init/+merge/333904 16:48 * meetingology rhaper/blackboxsw review https://code.launchpad.net/~rjschwei/cloud-init/+git/cloud-init/+merge/333904 17:22 thanks again folks. catch you next time. 17:23 minutes will be published to the link below 17:23 #link https://cloud-init.github.io/ 17:23 #endmeeting Generated by MeetBot 0.1.5 (http://wiki.ubuntu.com/meetingology)
