A

Hello, this is the Canadian grooming session of the bear o'clock. Today is the 25th of July 2018, and we are like one week before intial freeze, so I should share a screen and we should walk the back lot to see what tickets we have there for this.

B

B

Alright, so last time we let.

A

Me the master, so, let's see what's new first and then we can go through where we were last time. So this is a ticket a lot. Yesterday, I started seeing a pattern. People are having problems with load, both balancers and I, know the immediate reaction, like a load, balancer, honest and thorough scope for cab, a diem that is true, but we don't have. We don't define the requirements of our greatest concern in terms of a load balancer, for instance, I added some items here, like we don't define.

A

If L four is sufficient, we don't mention that it. A lot balancer has has to be true. Basically redirects secur secur requests, and we also have this, but we should probably not talk about this in the docs and I pinked a lot of people.

A

Basically, you have to provide feedback on what they are experiencing in different compromises like Asia is quite broken. I need promised Savannah boosters to comment on this I like Jason, provided a very good outline of what load balances aid operations, but overall I don't think we should write. Oh sorry, quote provider load balancer details the docs.

A

Instead, we should probably like have a list of requirements like what do you need from a load balancer in a call provider, so I started started, seeing problems in the cube ATM channel on the VMware internal slack and also Stack Overflow, and basically, people are trying different stuff and some of the load balancers simply don't work. For instance, if you have I, don't have helping routing it's a problem, so this is a new item. Hopefully, Richard can actually help with documenting parts of this. Anybody has any comments.

C

I'm sure, okay in documenting they require for the load balancer.

C

I think that if we have, let me say a good feedback from the community about what you can expect on the different cloud provider, I think that this will be vulnerable for the users.

D

It will prevent some headaches and also we, we bacon throughout a bunch of our things, there's some ideas about going from 1 to N for AJ and it might be beneficial to like you know before. Maybe it's something like planning your deployment. We actually have this and other Docs that I've seen or at least used to here, like it could be listed out as a set of like preconditions before you actually get to kuba DM deployment that you should think about these things as constraints for planning your deployment.

A

Yeah, we basically have so did this dog. We basically talked a little about load balancers, but I think this section needs some care.

A

Yeah, ok, hopefully you can get some updates in the cycle.

A

Let's say: I move to the next item.

A

So this was from four days ago. Let me see I forgot what this was.

C

This was a user that was asking the two that the control plane phase basically does not create a manifest. Is that my? If the manifest are ready exist on the disk and because, basically the user R is provided? He wants to provide in its own manifest because they are doing Cedeno. If I remember word, but.

A

huh So this is a part of the problem. I tried to explain yesterday, but I think I failed when you are presenting the customized cap.

A

We currently walk in the usage of phases in this regard, but yeah I understand the Cassell's.

C

I I commented that the solution for this one will be customized.

C

Okay, so in my opinion, we can leave this here and close as soon as the cap of a customized is approval.

A

Yeah so I was thinking again about this last slide. I think I found something that I wanted to share, but I forgot sorry. Basically, when you do upgrades I think you can avoid this whole stomping that we do on the manifests but yeah okay.

A

So this is covered. We spoke about this last time, the basically the market was this. The window strike initial there's nothing to talk about it apart from still on holds by Microsoft contributors.

A

It might not make it in our game, but the actual cap is merged, so maybe is going to make it this cycle as long as they can resolve those PowerShell script, problems that they have and.

A

Pointer our site in the PR for the system open. Let me try to summarize this.

A

There has to be a fail. Did you remember in the first place, to reproduce this.

A

Cluster status to miss the moment, so basically the key is that each team member has to fail and the note is technically failed.

A

C

You have an ethnicity complain, know that that basically is phase in a controlled way. So without calling about mineral set.

C

Then the problem is that Cooper being tries to connect to fooled and known atc, remember and when you try to connect to all the known ATC, the member and a member that does not exist. You, you eat a problem of go g, TR, PC client, which is used by TC d yep that basically it does not.

C

If the first point phase, it does not cost the second point- and there are discussion to fix this on etcd and I- think it is the best solution, yeah everything we try.

A

To do here, I think is we work her out, but.

C

A

Pair is still open. We should probably not merge it. It was already a great last cycle that we should not do this.

C

Yes, basically, the contributor was proposing to rotate. They served a ethnicity and point to bottom inside.

C

Which is really a workaround I would prefer to work this fix and in United States.

C

If we can link to the TCD work online.

C

It would be beneficial for the PR for the issue. At least you mean if we can comment on on this issue. At the end, this is going to be fixed at the anisa T V and the link to the ad city issue that I saw I, know I, don't remember if I saw in Guam was locked or in public dock gosh I don't have the link. Let me check this.

D

Is the GOP see my problem? Yes,.

C

D

Yeah that that one there will be a fix for that, probably in the 116 timeframe. So I don't think we should mandate.

A

That's recently, jia hao explained that he is going to work on this.

D

Yeah, there's well there's a way to work around this anyways I, don't know if it'll work, you have to change the list, order applied to each of the Supreme NCD notes and that that prevents the province's problem. There's a worker, no I do believe that there was planning to get this done for 116, I'm, gonna repaint him again. I do know that DIMMs reached out there's patches available for SD, but we need to merge that through KK and we'd also need to vendor an update at CD.

D

So we might want to attract that as a separate issue like update, a CD is a good example like whatever the tracking version is yeah.

A

I think the client version is still old in qadian with respect to kubernetes sorry and we are still on 3.3 dot ten, so this cycle, probably we can sync the versions and updates at the same time, I don't remember. Do you happen to remember the Nate, the title of the issue for in the Kiki.

D

Give me a second like in perspective.

C

I'm, starting as well.

C

D

Believe the issue number was in kk7 1 0.

C

Yes, I found it.

A

Ok, 7 1, 0 yep.

B

So 2 1 0, if you.

A

B

A

A

But do you want me to hold any show about sinking and CD 116 upgrading as well.

C

But I think that it is, should go in the main KK repo.

C

D

C

Also, we can close the PR that we have open.

B

B

A

A

Just sort passing within privileged user: this is a low priority. I think this is should be backward to be honest. Nobody discuss foreign service.

C

Even if it is annoying.

A

Do you experience this on your sites? Yes,.

C

Because I just changed the the my workstation and I eat the problem. I.

A

Think the fixture won't be that complicated, except that nobody is actually a report right to send a beer for this, but we close it I.

A

Think I. Remember yes, but also do you remember why we close this I.

E

A

So all of a sudden he's going to think what about this I?

A

What do you say, I think we can.

D

Never separate here, yeah they're, just I prepare that fixed it properly very closely it he closed the spirit, they've any open, a new one, I.

A

Don't recall, it's also not linked here yeah, the.

C

Province did exist because I eat properly yesterday.

A

Okay, so it's in master I.

B

A

Right I'm leaving this here, it's this for a feature, so we can possibly fix it. We can kick it out to the master if needed,.

A

This notebook- let's see who is active on this sorry.

C

Yeah go but I don't remember at the army. Yes,.

A

So it's not active hardcore, it is DCS a different path.

A

So that this is the default path or sorry, it's not the default path. It's doesn't CD right.

C

Yes, the user is good thing. They its own certificate under the default part I, see, I will start calling and.

A

How are we supposed to configure this?

A

So it's like a feature. Basically, we don't have a way to expose the hcv certificates. Vocation, no.

C

You can you can write the patent in this so.

A

This is not respected, basically, the full path here we.

A

Are not respecting these values and we are using now our own is this. One is couple.

A

Yes, exactly so that's not the.

B

D

It's a good to have I, don't think it's a requirement. It depends upon availability in priority.

D

No, no I think it's good long term I think the maybe just unassign it and leave it as Help Wanted, so people, if we get later in the cycle, people that want to do this can have time to do it. Okay,.

B

D

Don't I don't consider this to be a high priority. I found.

C

That people does not understand our life cycle active.

A

It's documented or it in multiple places. We are using it every day in multiple issues, but.

C

Unless not understand, if they see a sign, yet they don't pick up the issue. Yeah.

D

That's why I said unassigned it: okay.

A

Well, anything we can do here for now, unless somebody has the time to fix it. You.

C

Should not be difficult, I take nothing if I am asked. Yes,.

A

This is probably similar one.

A

Actually, let me take this with the security because it has certs, even if it's not a security breach.

A

Okay, cool 8/10 certificate file, path to chameleon config file field, so where, where do we pass? The client searching the config.

A

But that does it gives you.

B

Four mini cube: that's not sorry.

C

I think that we can close this one, because the user, because can mean.

C

All right I will take a look and see if I can close it and B well,.

A

First of all, we don't have an idea what the user has in this in this certificate authority here and also in this certificate directory. So how am I supposed to reproduce this.

D

I'm guessing they're, just setting up mini queue.

D

Who's, the author.

A

I think this should be directed to mini cube if they ping us with a hey, you're doing something wrong. We can then proceed, but this seems like.

D

A

D

A test it with a different location to verify to see if the settings work properly. Even if it's not, you can check to make sure that the overrides through the configure, all working as they should be, and that's like a first step before closings I- think that's that good diligence is probably reasonable.

D

A

Actually, this okay, so the user is confusing me because the couplet class certificates in the title- but this this is not the club couplet class.

C

Certificates, if the fact is I understand in this way that we generate some our configuration for Kubrat, it is done by two pieces. One is the Cooper configuration and the other is the they defy with the environment variables and defy with the Parliament variables.

C

Otherwise, the configuration, okay and and the user is trying to change a setting that is in the in the environment file with a setting in the configuration file. I.

C

Don't think that is the disappoint of this change.

C

And it's just what we write in the coop I.

A

Am inclined to remove this from the mouth? Oh yeah.

C

At least we would like to ask: why do you are not using a default place for the certificate.

C

Is there a special reason for not respecting the falls in this case.

A

Let's suppose this is: let's move the next one is now outside of the mouse hole, so they have to reply. If you want, if we should be able to see it okay, this is search in bullets.

A

Dns the score approach: what does DNS discovery mean?

A

Are we talking about.

A

Discovery she discovered I, remember.

B

I, remember: okay,.

A

I, remember yes, so I guess another HCD feature may be something and it CD. That is a problem.

D

There is a DNS discovery capability for Etsy team members. I'd be surprised if we could support that, given our configuration unless it was like totally external at CD and somehow plumb that through that would have to be how how you configure it. But that's like a weird: it's like a bootstrap problem right because you need it need a special ordering to make this even possible, so like you'd, have to plumb through I know how it works. You'd have to plumb through the members from DNS discovery into the API server arms, and it's just I.

D

It's a weird scenario like I get what they're doing, but you you can't there's no dynamic way to do this with how we configure we'd have to plummet.

C

If I continued, if I remember, while I suggested to the user to create the disunity, trust her with discovery and then past the cluster using a thermal ABCD, if you scroll down.

C

I think they did pretty well to the this comment, divide the program to pass a create and estimate the city. Cluster user Cooper mean to create a class that they use and estimate the city. Let's seal the way you can do it I think it should close, it say sure, I'm foreclosing, there are not no feedback.

C

Like solo HD is the melding for this comment, because it seemed that the problem is solvent. Rebuttal, a really lot has come. I ok, created PSA better at the mall include, is correct by repair.

A

Ok, it's soft because I was ok, so called miss key. What if.

C

There are ever needed 53 for.

C

D

We could document this as a proposed configure like part of the setting up your deployment, and if we have part of the external entity configuration you could possibly add a blurb. That basically says you know, so this is not a fully dynamic system. If you want to sort of externality DNS rally point stuff, then you need to set us up music tournament. Cd.

C

For best for this thermal TC, you know we are not documented external TCP I, don't remember! If you there.

D

Was there was documented Chuck originally wrote that I don't know whether or not we still have it or not, because we had the documentation, which said like here's, how you provision it CD using phases with comedian? It's the first link.

D

There is there's, there's two parts: there is the stack master configuration than with external.

A

So this is the high availability creation page. We have a separate page that has instructions how to set up the Excel sequestered.

A

But we never I know these documents that we never talk about discovery service and that it's not supported for stacked I think we should add a sentence somewhere, possibly in the high availability. Doc. Let's say hey. If you want to use, you know, name name server for for the endpoints of a CD. You should use external HDD or apply is possibly not mentioned this hack that users drink nobody. It.

C

Is not the user was confused at the end, AE understood that that he have to do to create a testament, ECT and then to create and then to pass the eighty CD and point to provide me. Yes,.

A

But what happens if another user tries the same to basically configure n CD with these flags, because we hello extract acts to eight CD? Well, this is going to fail unless they get the correct flag. Well,.

D

I agree that it's it's a confused users. The deployment that he's trying to do is it's awkward, I think he's learning and understanding the order in which he do things that.

C

He brought to these I'm learning and and then explain it and he understood exactly.

D

C

I I'd move to just close, yes, okay, just close, and then we found over to the property fixity. If there are four third week of place reopened start something senior.

C

And we forgot to the couple mean: documentation and I really about the city and really looking for more opportunities and end point users to a CD at me.

A

This might not have a very strong.

A

Okay, we have to work on its medium because it's understaffed is a longer statement.

A

A

Simplify I forgot, where we are again senator.

A

A

Did we look at the previous world?

A

Yes, this one? Where is this one.

A

Failure to draw awareness, so this.

C

Is this is part of our design? We should close. This I think I think that I commented them, and this okay.

A

Let you talk about this optical.

C

Yes and and then we shall link to the to the issue about the customized.

A

Choice: okay, I'll. Try to find the issue quickly. I will.

C

Search for you probably a bit too open.

B

A

I got it and you're faster than me. Alright have searched for this issue so many times, and we have a set of excuses that we.

C

Reuse, but this is going to up and I sent it PR today.

A

Close and also its unsupported did you explain that it's not supported? Yes, so how.

C

So it's not supported if the user that does it. Yes, I, think that the real comment is one free. But if you do this see it's all supported, but if you do the.

A

Customization, it's all supported.

C

A

Comment, this will.

C

Be possible: this will be possible when customization major, but this win.

C

But I think I want to be supported.

A

A

Maybe forgive me don't know for a while.

B

Right right, this.

A

Marker this one initiation was a so. This is Lucas also planned to duplicate to this, but I closed it originally Rafael reported. You know this is an artifact of the face level where we have to specify the face up on certs, but we also need experimental upon certain, which is now a broad search. So we have not much limits a broad search. The confusion here is that we need an extra part pass to the command that has a verb in the name as well.

A

I, personally, don't care much about this I think it's fine as long as it's documented users already have. This users can already see this in the box.

D

So I believe it open. I mean it's it's a wart on the user. Experience would be just leave it as Help Wanted. He doesn't need to be for this cycle. If anyone wants to attack it in this cycle, they can.

A

Do its other two mixed yeah.

D

Long term important Help, Wanted.

D

I just had a quick question before we keep going here like I've seen. How is the new contributor experience been going? We had like an influx of new people for a while and I kind of dropped off for a beard and.

C

Yes, we having a currently we don't care I.

A

Can give some feedback? There is a guy who works for a pivotal called Ben moss and he is a colleague of people like Leah who attempted to contribute to comedian and they walked our backlog. We saw some like lost cue tickets. They started sending Pierce immediate without discussion. We closed some peers.

A

There helped with writing the notes of you know the notes during the meeting taking notes, but then explained to me that this was also not a guy who attempted to join question about developments from Utah, but they are really discouraged and I. Don't think he's read the people I think it's a complexity of the projects and maybe the whole development model is really not.

D

What the it's more, the development model and pivotal in particular, so I, wouldn't necessarily take I, wouldn't extract pivotal as a general user story because of how pivot operates, they rotate people and they rotated them off. So unless you actually get engaged with the SIG's and understand the flow and the people yeah, and especially if they rotate people in and out, because really difficult, because by the time they're done or the rotation and by the way, Ben moss and léa léa are both rotated out.

D

Currently, there are no pivotal contributors to anything other than like passive participants. Another safes yeah.

A

Ben is I, think I'm working on sig windows in his free time, I'm, not sure anyway, I. Don't it's really complicated, then to the question of how is a complete, we should my opinion is that we should have got more and more videos explaining different parts of debate. Am the testing process. We can explain kinder. We can explain how we work on features during the cycle. Things like that. If we have a bunch of videos, we can just do this. Another.

D

Thing that might help to is like we have an incredibly user base like it's just just by posting in the Kebede ian. I don't really go to the convenience lecture anymore, because it's like a fire hose, but just by posting, a cuvette DM slack channel, saying, like hey, we're looking for new contributors, if you're interested here's a video for onboarding that might be, or if you're interested in becoming a new contributor to sit closer lifecycle, here's non-boring video that alone might be a first pass stuff and I can take as an actually.

C

The other problem that I see is that in the backlog we are, we have a lot of nasty issues which are not very well documented or not easy to address. They are there for forever, and so when people arrive, Cooperman is easy a so there is no area and you see flow in inflow of new feature or new new blogs that we ever so. That is a kind of stuck in it or not to call it it. We are. We are getting stable, so I.

D

Prefer to use the word maturity if.

A

So we have to remember another big problem is that if you are not on a salary to work on something that is ready to to cube ATM or coaster API, it's really quite special case for people to join these projects for bid show you're one example. There are not many people like you, Lucas is I, guess also an example, but he's kind of more involved. But it's really. We don't have contributors that do this in the three times, so it's tricky well I think there.

D

Has to be a subtle motivation like internal motivation, if they're using PDM to solve their problems, if it just works from 90% of their use case, they're very inclined not to care right, but I think finding those people, maybe in the selection, who are having problems for our developers. You know we can help guide them along the way, but typically I don't have the resources or bandwidth to identify those people. Yeah.

C

Some time ago, I started to list of potential new, really simple small change. Small cleanups I have to search for this document and start finding these issues for first contributor and then try to make them visible and I have to search for yeah.

D

A lot of the issues we have right now are very thorny right. It required deep knowledge, but if we were to do a Code walkthrough, that might be a good way because there's a lot of low-hanging cleanup work that could be done, but we haven't really enumerated. That stuff, like Richie, was talking about. Yes,.

C

I think that we have to work on on feeling that the backlog with small things will change more clean up, and this create then the cycle that that user start from simple things and then move on to more complex beings. They, the current backlog, is not easy for an you know for a newcomer and.

D

I would not generalize from pivot on just as a tldr hammer.

A

Okay, for this one I send a Pierrot ready. The TLDR here is that we have a user.

D

A

Trying to add to use the to skip the proxy phase perform an update on the same cluster.

A

This failed with to my if I remember correctly, with a new pointer exception rusty. You commented on my PR, which has been in frightful since May. Do you remember, let me show you the disk. We CLE you can recollect so.

A

This particular check: do you think that we it's ever going to be a value that this a new here I think we had this case basically I.

E

Think it's never going to be new simply because it's forced to a non nil value in, say: dynamic default function so.

A

How can we see if the two proxy is not deployed? Should we create a client and check the cluster.

E

Probably does the most correct thing we can do right now: okay,.

C

I'm leaving to work instead of each they users keep facing, we have to provide the equivalent on updates the deaths, the real solution, yeah.

A

We have a tracking issue for upgrade phases: I, don't remember where it was I. Think it's in the mouse own machine, alright see the bottom. Okay, we have a ticket for that already okay, so this is active.

A

Should I close that PR pretty much?

A

mmm Let me let me get back to this offline after the meeting. Okay.

B

A

Right computer secure serving Fukudome scheduler.

A

Why do we want to do this?

A

Insecure service application, so I think we've had a bit of a problem here. I know.

C

One started to work to this one remember.

B

Our backdrop see I.

A

Think this is still viable I.

B

A

B

B

Actually, let this thing up Josh.

B

So it's a fix for that particular.

A

Pr I don't remember this, but it's a bit nice rebase, maybe I should paint Josh.

A

You see responses, maybe we are blocking him. I, don't know, I need to get back to these tickets, doesn't bear any mass or it is PR. Does anybody remember this PR you.

B

Know this is not resolved yet.

B

Let me look at this quickly. 15 minutes.

A

So, whenever H is appears here, changing the port, okay.

B

Which is probably not okay,.

A

So here is pretty simple, but there is discretion. Let me cinturón excuse talk a lot.

A

So we have to add extra flex.

B

Telling me what.

A

Okay, I, don't have I talked out the knowledge here. I need with this year.

C

If we can get rid of the unsecured line desk, probables I mean is a good thing. You want to support insecurity objects. Now, if you can get rid of unsecure so move to secure as I checked with me, it will be nice.

C

Well, it's in C now I think that we are always doing unsecured checks. Yes, but.

A

The question is how to move to secure at all the same I need to understand what Stefan scopes out here. Yeah.

C

D

Have to investigate this as well. This might be a higher priority. I put a priority important soon. This has been ongoing and folks are pinging on this issue. Particular my.

A

Problem with solve these higher priorities that that is that we should not among these people have done with to work on them and if they are assigned. So if a breacher is the same here, do you want priority important role.

A

Because if we leave something that is like Help Wanted with priority critic, origin I, don't think they Merton. They mix the two tax.

A

We have to have immediate people that react, and it's that.

D

Story, we can just leave it a sign for right now, but it might priority invert from downstream conversations.

D

A

Well, Joseph I think Josh on the ticket. We should think him internally. If there is requirement to escalate this earth. I guess.

A

Too much Sun, we have eight minutes.

A

We find my name because he this has been going for a while, so Eduardo Santiago happy contributing their roster. Do you know the TLDR? Are we done with this I think we have another small item by the yago descending.

E

Can you scroll to the bottom of.

A

This basically, he wanted to create a map for coordinates what is hidden so to simplify unit tests.

E

Yep, probably I think there was some work in this direction, but I'm not sure whether it's like merge tour I'm.

A

Going to put this two legs because it's unit, this is not important long.

E

Yeah, this is mostly made already.

E

A

It's active but arguably because Yahoo is probably busy with work.

A

B

Okay, Lucas so deprecated its features. This is fairly I'm. Sorry on the statement.

A

So this is like it's just about the duplicated couplet Fox, to be honest, not going away anytime soon, so I'm wondering what to do with this ticket.

E

So I actually reviewed it a couple of months ago and yeah. It depends on this PR based, but it was quote so we probably shouldn't do anything at this point. Well,.

A

Mike Dauphin is going to ping us immediately if they start removing flags to buy on the scenic. We cannot avoid some of the flags right now by the way the dakichan flags are these deprecated. That's silly question.

E

We don't know that we should probably ask dibs about it. So.

A

We have another ticket that is striking the dock regime stuff. Should we close this because the flags we cannot.

A

So let me ask another question, so the C group driver we use the signal driver override from the command line. Somebody said appear to change that, but the Stig got discouraged. Then they closed the pier. Do you remember that, like a couple days ago,.

E

Yeah I remember pyaare.

A

Okay, so this is still valid, I guess we should leave it in that case, because we use the C group five over right, yeah.

E

But we should probably wait for Mike dolphin to make a little bit more of those facts into the config and probably scrub the entire flag, all right stuff.

A

Moving to next any objections no depends on. It depends from other people very much all right. Well also a little bit on us with the one of the overrides okay.

A

Of the texts again cut, oh sorry, again, a deprecated. This is like a duplicate.

A

This is duplicate of the other. The other one contains implicit couple. Facts like that. This is the same pretty much but I forgot where I just cause they're. Let me.

A

You have three minutes.

A

Somebody's reading, each other cannot see it. Okay, thanks Tim.

A

Let me let me quickly, link from cause this one I need to the for the basic, but the one from check, because we have a couple of issues with the same stuff.

B
