Description

March 10 2021 meeting of the Kubernetes IoT Edge Working Group. Small group open forum discussion: KubeCon EU CFP recap.Tokyo Kubernetes user group, K3S vs KubeEdge architecture

A

Can you hear me.

B

C

A

How are you doing hey.

C

Good, how are you.

A

C

Yeah, so you just yeah, so just you and me yeah.

A

A private meeting yeah, oh here's, his moritz as well the usual suspect.

A

That's good! That's good! Good morning.

D

Hey there, oh, I really need a coffee.

A

It's way too early here, yeah.

A

This is 6am in the winter in europe, so these are always hard for me.

A

So what time is in in japan.

C

It's uh it's 2pm, 2pm, okay, nice yeah! It's! uh It's really! You know like easy, pacific friendly.

A

Yeah, that's what we strive for, I I hoped in in the beginning. We will have much more uh much more people for for apec joining in, but that didn't happen a lot. Unfortunately,.

C

Yeah, but I I think you know like uh like like it's iot devices, I think there would be a lot of user. You know.

B

C

Like japan, china I'm sure they they are working on that.

C

Maybe they don't know this working group. I don't know.

A

Yeah, so any topics for today you would like to discuss.

C

Not exactly for from me, I just uh you know I am, we are excited to participate in the cubicle. It's I yeah yeah.

A

Yes, so uh you didn't get, let me see if that went out.

A

Or not just give me a sec to take a look.

A

A

So did you get your notification uh uh about kubecon? Yes, yes, awesome.

C

Yeah yep, I yeah. I did too.

A

Yeah so so both of your your proposals were accepted.

A

It would be a good event, so there was a lot of a lot of sessions. We try to pick to get a good balance. You know so robotic the industrial telcos and uh a little bit of community updates and projects.

D

A

Yeah, I think it will be a good event, so we can, we can have it more in the future.

A

How is your event going on where it's planning.

D

uh So pretty good so far, we're still like working on the siemens guys uh and I think our invitation mail will go out today or tomorrow, um but yeah. It should be. This sergious, I think uh of march, but still like it's really small so could be, can be quite easy. It's getting rescheduled! If you know what I mean.

D

D

Yeah, it's gonna be fun. It's like uh the approach is quite interesting that we have like like different.

D

I mean you have guys from like cements and from sango bar and then from um matic.

A

D

Well, um and just talking to them in the beginning, and just talking to them about edge is like so funny because, like I mean talk to siemens guy or to a boss, guy about edge is like, like completely different thing about like talking to others like. Oh, no. No, you.

B

D

A

Yeah I mean there's different perspectives, that that's always that it's always a challenge for this working group as well, right so yeah, everybody coming and and yeah everything from from on-premise computing to to you know, powerful devices is, is the edge or or, like uh you know, telco data centers. Everything is.

D

I mean it really also depends on the use case right so I mean, if you're like the guys, who I don't know, have these rent me bikes or something like that where you have like these little chips in there. um I can totally understand that that is the edge. Basically, um on the other hand, I don't know if you take, for example, industrial engineering where you have like, I don't know machines that cost up to. I don't know two million dollars or something like that.

D

It really is like oh yeah. I could like fit a whole data center fit like. I don't know one one machine with like. I don't know um power, backup and multiple network connections, and so that, because my machine is two million dollars- and I don't want it to stop so I can put a lot of hardware in there and this becomes like a little data center and you're just like yeah, that's not the same.

A

To me, what's always fit the most so like on-premise computing is, is not new right. People are doing it for decades. uh What I think you know in my my opinion, what different differentiates edge computing from from on-premise computing is, is to, and then you know, iot devices and- and things like that is- is cloud native development so trying to do the same development process both for the cloud and and and for for the edge sites and then and trying to make it like a seamless system overall right, not one.

C

And the access.

A

D

I think that's also like the biggest.

D

Progress in the last few years regarding that.

A

D

Like like what I had like, I started with was electrical engineering and basically moved up into all this cloud stuff, and um once you get to the point where you like, build everything the same, it doesn't really matter what you build anymore.

A

D

So because everything is just a basic docker image, so everybody- I also my my students and everybody I talk to is just like. Oh man, that's really easy because I just need, like I don't know, a rest or just face, and then I do whatever I want in behind that and then I just build these services and you're like yeah. Basically, that's it. That's.

A

D

D

Yeah and um it's really funny to see because a lot of people are now like moving into other industries, because of that, like you start with with some kind of engineering.

B

D

Like all these crazy, I don't know uh plc or gpio, programming or whatnot, um which of course is nice, but normally the manufacturing industry doesn't pay that well for farmers, because the scaling isn't that big normally like I don't know like a like a laser production machine if they sell 100 of those per year. That's normally quite huge, so like like a software developer on the other end, doesn't have like this huge impact.

D

If you know what I mean, of course, if you go into like the cloud native area or the big data area, it's just like you know so so what I see happening is a lot of my students always all go to like all these crazy. I don't know consultancies or all these crazy software development uh startups and you're, just like oh, come on guys just stay.

B

D

A

Yeah yeah yeah.

D

So the brain drain is.

D

A

Cool, I saw the other day tomorrow the the cool automotive uh project from sony. What's called visual s vision, s yeah,.

C

Yeah, it's a automotive project, yeah yeah.

A

It's really really cool.

C

Yeah, but I I don't know very much about that project, but yeah it just started yeah we have the poc, I mean like we. I have never seen that in fresh yeah. So I don't know. I don't know the like details but oh like uh yeah, but I think the concept is like we can develop the sensor devices.

B

C

On that prototype, so now you know like we are trying to find the use cases based on that prototype and we can adjust and develop new devices for the next generation. So I think that's the that's the logic for that.

A

Yeah yeah business. I think.

C

A

Yeah, that's that's what I got as well from the.

C

Yeah, but I mean like including autonomous driving, some vendors are trying to use the kubernetes right like toyota denzel.

C

Of course we are yeah, so that's somewhere that kubernetes can go yeah yeah.

C

I got a quick question actually so, uh once it comes to the edge iot devices you know like we confirmed, you know like raspberry, pi 4 and even the raspberry pi 3 can run kubernetes.

C

Of course, there is some like a cpu consumption like five six percent for the cubelet, but if that, if we have to support much smaller platform compared to raspberry pi, what would you think we could use like a cube edge or k3s?

C

Have you been? You know like in there.

A

Not that much, but in theory, yes and and in in interior, also you can, you can use, I mean depending you know, do you need a full cluster there or or can you run just uh just a container with with some basic provisioning? So I I know that people are experimenting with running just docker or podman on the edge, and then you know.

A

And then, from that perspective you know, don't have much other stuff there, but yeah.

C

Actually, we would, if possible, we would like the full control for the cluster, so.

A

C

That edge a small edge device uh if possible, it should be aware of the cluster so yeah I was thinking so you know, like maybe the cube edge. I I I already tried to use and it's really optimized. I mean like, like a memory footprint and a cpu.

B

C

It's pretty low, I mean like, even if the raspberry pi 3 is.

A

C

A

Yeah I mean that that would work pretty well yeah and, and then you know so the the main difference between using uh cube edge or q q k 3 s is: do you need to your device to behave like a node or or like a whole cluster? That's that's!

A

Oh because k3s is scaled down whole kubernetes cluster that you can run on on a smaller device with with kubernetes. You have a centralized control plane and then your your your. Your devices are basically nodes right.

C

Yeah, so actually the cube edge is like a small devices, just shooting at a sensing device up to the cloud right and that.

A

C

Can be controlled in the cluster but yeah.

B

They're actually.

C

The device they basically cannot be, you know like we cannot control the deployment. It's actually just shooting up design sensing data from the edge to cloud so yeah.

A

C

Yeah, actually, there's one more thing: it just popped up popped up. My head. Yes,.

A

C

That's why we're here yeah there there is, uh you know, like you, said like uh there is not a lot of people to participate in this asia pacific time.

B

C

You know that something like I can do is like. uh There is like a meet up in tokyo like.

B

C

That's called kubernetes meetup tokyo.

A

C

I have been, I have been there for a few times, uh so maybe you know if we would want more participants, maybe there's something I can do is I can you know, introduce this the working globe to absolutely.

D

C

Yeah yeah, let me let me consider uh if I can do that yeah I will you know like. If, if I have a plan uh concrete plan, I will make contact with you.

A

Before the presentation.

C

A

If, if, if yeah, if you want us to do something there, I mean you know, give a brief presentation or something like that: that's that's! Blue. Okay,.

C

Sounds great yeah yeah? Actually the communities made up tokyo is kind of huge, like almost 500 people are always there so yeah, it's huge. So maybe that that's some something we want to. We want to expose.

C

To get more information on the part yeah.

A

Yeah, absolutely it would be great to see you know if if people are interested in in you know doing I'm sure they are, I mean right in in the interesting settings in the iot stuff, doing edge computing exactly.

C

A

I mean that would be awesome.

C

Yeah more idea, the better.

A

Yeah cool, so I don't know if you don't have any any more topics. Maybe we can adjourn for now.

D

B

I think you should, I think you should yeah.

A

Spoke to you guys, online, okay,.

B

Yeah see ya yeah yeah.
