16:09 <blackboxsw> 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 <smoser> o/
16:10 <blackboxsw> 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 <blackboxsw> #topic Previous Actions
16:11 <blackboxsw> last action items are listed in our meeting minutes at the following url:
16:11 <blackboxsw> #link https://cloud-init.github.io/status-2018-05-29.html#status-2018-05-29
16:12 <blackboxsw> #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 <blackboxsw> that was a carryover from the meeting before I believe.
16:13 <blackboxsw> #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 <blackboxsw> 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 <blackboxsw> smoser: and rharper drew up a hackmd doc related to this work here:
16:14 <blackboxsw> #link https://hackmd.io/NUUO4nndS4CXTItl8Rs6Nw
16:15 <blackboxsw> 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 <blackboxsw> a WIP branch is available here
16:16 <blackboxsw> #link expectation is to get the foundation landed this week
16:16 <blackboxsw> and tracked in trello here
16:16 <blackboxsw> #link https://trello.com/c/Yp6VG2lP/837-eventpolicy-foundation-for-joyent-and-azure-coldplug
16:17 <robjo> 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 <rharper> is it instance restart or "re DHCP" ?
16:17 <rharper> ie, bounce the interface ?
16:17 <blackboxsw> #link https://code.launchpad.net/~chad.smith/cloud-init/+git/cloud-init/+ref/feature/maintain-network-on-boot
16:18 <smoser> robjo: that is correct.
16:18 <robjo> so a re-read of the metadata on EC2 delivers no/maybe limited new information
16:18 <smoser> robjo: well, network information is updated.
16:18 <smoser> user-data is only updatable on stop -> start in ec2
16:18 <robjo> rharper: AFAIK new metadat gets pick up on instance restart
16:19 <rharper> ok
16:19 <robjo> I know the IID also only gets updated on stop-start
16:19 <blackboxsw> 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 <robjo> Yes, in Azure adding network interfaces is not dynamic
16:20 <robjo> meaning cannot happen while an instance is running
16:21 <blackboxsw> 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 <blackboxsw> https://hackmd.io/aODzXfa_TOikNtYBLt8erA
16:21 <blackboxsw> #link https://hackmd.io/aODzXfa_TOikNtYBLt8erA
16:22 <robjo> Also for Azure there exists the "problem" of accelerated networking, i.e. SR-IOV
16:23 <robjo> when accelerated networking is on the SR-IOV interface gets the same MAC address as the "Synthetic nic"
16:23 <rharper> well, they "solved" it by having the kernel auto bond =/
16:23 <robjo> 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 <rharper> AFAICT, the sriov device just magically comes and goes as it will
16:24 <rharper> so, one shouldn't worry about the silent bonding ...  (I'm being a bit sarcastic here)
16:24 <robjo> 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 <rharper> we ignore any of the mlx4 driver devices
16:25 <rharper> yes they show up
16:25 <robjo> OK
16:25 <rharper> but the directive we got was to ignore them; and DHCP on the netvsc ones
16:25 <blackboxsw> ...so think that's all I had on action items from previous meeting.
16:26 <blackboxsw> shall we go to next topic?
16:26 <robjo> And that of course works until Msft gets a better HW deal from Intel or someone else for their network cards ;)
16:26 <blackboxsw> heh
16:26 <rharper> robjo: indeed
16:27 <blackboxsw> #topic Recent Changes

16:28 <blackboxsw> thanks again Robert for the contributions here getting cloud-init in order :)
16:30 <blackboxsw> we've also just pushed a release of cloud-init tip into Ubuntu Cosmic.
16:30 <blackboxsw> so all latest changes are in the development series
16:32 <blackboxsw> I think that about wraps it
16:32 <blackboxsw> #topc In-progress Development
16:32 <blackboxsw> As always, we track ongoing work publicly at
16:32 <blackboxsw> #link https://trello.com/b/hFtWKUn3/daily-cloud-init-curtin
16:33 <blackboxsw> we've got some cold-plug network rendering handling that will be queued for this week, mgerts is working on enabling cold-plug network rendering support on boot for SmartOS, and there is a followup for Azure to do the same
16:34 <blackboxsw> cloud-init squad is going to be setting up an SRU into Xenial, Artful and Bionic this week as well
16:34 <blackboxsw> to sync latest qualified cloud-init into those Ubuntu series
16:35 <smoser> blackboxsw: thinking out loud..
16:35 <smoser> if we're going to release 18.3 on thursday
16:35 <smoser> might as well just hold off on sru until then
16:35 <blackboxsw> (wait on 18.3 release?)
16:36 <blackboxsw> yeha
16:36 <blackboxsw> yeah even
16:36 <blackboxsw> which brings us to our next topic
16:36 <blackboxsw> #topic Cloud-init 18.3 release
16:37 <blackboxsw> I hadn't seen any responsed to your email scott to cloud-init@lists.launchpad.net.  Does anyone have any feature pressing that we'd like to get into this release
16:38 <blackboxsw> estimated release would be Thusday of this week
16:39 <blackboxsw> 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 <blackboxsw> s/whimsically/opportunitically/
16:39 <blackboxsw> heh I give up
16:42 <blackboxsw> did we want to pull this in? https://code.launchpad.net/~paul-meyer/cloud-init/+git/cloud-init/+merge/334989
16:45 <blackboxsw> 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 <blackboxsw> we'll SRU 18.3 then into Xenial, Artful and Bionic after a complete round of testing.
16:46 <blackboxsw> #topic Office Hours (next ~30 mins)
16:46 <robjo> :D After 18.3 but before the workshop: https://code.launchpad.net/~rjschwei/cloud-init/+git/cloud-init/+merge/333904
16:47 <blackboxsw> Folks are around for further discussion on any cloud-init topics of interest
16:47 <robjo> then maybe at the workshop we can come up with a way to move SLES & openSUSE to sysconfig renderer
16:48 <blackboxsw> good topic idea
16:48 <blackboxsw> #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 <blackboxsw> thanks again folks. catch you next time.
