This was a short meeting due to many folks attending KubeCon EU this week.

Topics:
- Cascading deletes of machines
- Status of MachineDeployment controller
- ProviderStatus on machines
- Status of migration to the cluster-api repository

A

Hello and welcome to the may 2nd 2018 mission of the cluster API breakout meeting. First, a cluster lifecycle, Devon I'll. Let you kick it off, because you have the first item on agenda Thanks. So on.

B

Our side we're just starting to get in a position where we own- oh, nothing,.

A

At all, you don't appear to be muted. I, see you moving. Oh.

A

Maybe it's just me.

B

Any luck yet I.

C

B

D

Yeah, it's four: okay: okay,.

A

Well, uh can other people give like a thumbs-up thumbs-down whether they can hear Devon? Okay, so be interesting to see if the recording can hear you.

A

Both other people can hear you. Why don't you you keep going okay, so.

B

Are we're starting to get a position where we can start using this API a bunch more? We had kind of our API and we're trying to pivot to the API working on here. I think we're getting closer to that. So we're starting to have a lot of questions, and hopefully we can help out a little bit. um What a couple of things that we wanted to ask initially, were we.

B

We noticed that it seems that deleting a machine set today, the machines that belong to that machine set remain, and we were wondering if that is intentional. It was kind of contrary to what we would have expected. We would have thought if you delete your machine set, the the machines would get cleaned up and it seems like that might come into play when we start dealing with machine deployments. So we were wondering if that would be a reasonable change to put in.

B

D

Any of that yeah I doesn't seem like you got it I, don't think it's very caring anything.

D

Let me that seems a reasonable that since arisen will change to me. I would.

E

Also expect that didn't she deployment sets with deleted machines when there's deleted. Unless, like explicitly stated, it should be an option on the machine set like just like. We have it on Damon sets and deployments or, like you, don't delete your children. I would assume that you would have some option like that, and machine deployments actually does rely on machine said, deleting the machines under underneath. So the machine deployment controllers is work in progress and we hope to send it out review this week.

B

Ok, that's that's really exciting. That was my next question was where that was because we were looking at using that as well. um Ok, so that's good! So maybe we have you implemented anything on your side for cleaning up the machines from the machine set. Yeah. No we've just I've just been looking.

E

At the deployment code and figuring out what goes into commercial deployments and what doesn't and.

D

Actually, Kenny Kenny just joined a call and I Kenny there's a question: oh no machines that are not deleting the machines. I, don't know. If you're looking to any of that code, cuz you're, like looking at the resource, teardown.

D

It doesn't look like his hearing. Yes, ok, second, more technical difficulties, Kenny's.

E

Audio isn't working.

D

F

E

B

This ok, so what one will do? Maybe we'll try and poke around that on our side. If anybody does have anything in progress, just let us know on slack and and we'll stop, but if not we'll see if we can maybe get that added. Do you mind opening go would get her by shape so that we can track sure. Absolutely that's it. Yeah yeah.

D

Yeah anything that had come across police files on a show, so we don't kind of work on the same thing. I guess: ok,.

B

Will do thank you, yeah. Thank you.

C

Okay, so can you guys hear me, okay, cool so so the other question we had and I'm working with that I was on status right so right now the provider specific things are in getting CETIS annotations on machines such as, like your machine cloud provider, ID and so on, and I was wondering if there can be a more structured way of storing these things than just annotations.

C

So we have. We have a string on the on the cluster to store cluster cloud provider. Specific things and I was wondering if something like that can exist on on specific machines.

C

The other question I had related to that is that, right now, the provider specific status own clusters is just a strainer, be it things like following the pattern the provider can take. It should be a long extension or or structured. That includes a long extension so that we can restore proper struct there. Any thoughts on that.

F

So I'm curious what the rationale was, because internally we just copied that convention. My rationale for advocating for the string was that then it would be an opaque value so that we wouldn't commit to any particular structure for the battery specific configuration.

F

C

The wrong extension gives you that right, but it's it's, it allows you to structure, JSON or Yama whatever inside that field, as opposed to serializing. First to Australia.

C

So it's the same thing: it's just the that you're you're using long extension, that's supposed to strip.

F

C

So what I won't do is go ahead, create an issue on the repo and.

C

If we get agreement on submit.

D

That sounds like a good next step, then I think it can help with a discussion in a more structured way as well.

D

Okay, I think the next one on the item on the agenda is, is around just logistics on the repo, so Chris Nova sent sent out a PR just a couple of days back then, which will remove the code from Q to play and, and everything has been migrated and I was successfully to cluster API I. Think there's nothing missing earth, so I, don't know if or crease others don't have any any any updates but other otherwise. You know that should be the new repo dunno point forward. So, oh she would they playing more.

D

Do we have anything else on the agenda or anything else you'd like to meet to discuss.

D

Okay, I guess not, so thank you.
