WEBVTT 00:00.000 --> 00:09.000 This is everyone, be quiet. Next talk is up. 00:09.000 --> 00:18.000 Cool. Is this good? 00:18.000 --> 00:25.000 Good. Awesome. Hello everybody. Welcome to this talk. 00:25.000 --> 00:30.000 This talk. My name is Nadia. I'm a Senior Software Engineer at Grafana Labs. 00:30.000 --> 00:35.000 My goal for today is to convince you to run your city painter in Kubernetes. 00:35.000 --> 00:41.000 If I'm not, if other man has to do that, at least I hope I can show you how to run your 00:41.000 --> 00:47.000 Vibrinder on Kubernetes. So this is like a very quick talk. I have very few time. 00:47.000 --> 00:54.000 So let's start maybe getting something to print and then we can see if that works. 00:54.000 --> 01:01.000 Hopefully it is moving, so hopefully it won't set itself on fire. 01:01.000 --> 01:06.000 Okay. Let's start. Again, quiet. Not interesting. What are we going to talk today? 01:06.000 --> 01:12.000 So I'm going to try to explain you why. I think you should do this. Why did I do this? 01:12.000 --> 01:15.000 This is like again the main focus and I'm here to convince you. 01:15.000 --> 01:18.000 Then maybe how if you are still interested after that. 01:18.000 --> 01:25.000 And then I like to talk briefly about the future of this if there is there is even one. 01:25.000 --> 01:29.000 Okay. So again, why should I do this? Why should you do this? 01:29.000 --> 01:33.000 So do you know what this is? Raise your hand. Hands up. 01:33.000 --> 01:39.000 Okay. You're thinking this is a Raspberry Pi. I mean you're not wrong, but this is not my point. 01:39.000 --> 01:43.000 This is a pet. This is buff. Pets are buff. 01:43.000 --> 01:49.000 Well, maybe I mean robot pets are buff. Well, maybe I know pet of you and they are they are not. 01:49.000 --> 01:53.000 So maybe maybe I guess my point is that the Raspberry Pi is buff after all. 01:53.000 --> 02:01.000 So if I haven't convinced you by this terminally online joke, I have a very nice table to show you. 02:01.000 --> 02:09.000 But the point I want to convey is that your 3D printer, it can be as no flick, but it doesn't have to be as no flick. 02:09.000 --> 02:16.000 So this is the table I want to show you. If you are corporate minded, this will for sure change your mind. 02:16.000 --> 02:24.000 So what do you get from Ranger's 3D printer in Kubernetes versus in that Raspberry Pi that you have had in a drawer for 3 years? 02:24.000 --> 02:32.000 Okay. If you want to run your 3D printer in, if you're running a modern 3D printer, you may actually need quite a lot of stuff, right? 02:32.000 --> 02:39.000 You probably want an HDP server to connect to the printer. So who is going to be doing that HDP serving? 02:39.000 --> 02:44.000 If you use Kubernetes, that's your English controller. You know that it works fantastically. 02:44.000 --> 02:50.000 It integrates, it does TLS for you. It integrates with less in-create. It integrates with DNS, if you are fancy. 02:50.000 --> 02:57.000 Without buying a drawer that's, you know, some server in there, you probably didn't install because you flash this from somewhere. 02:57.000 --> 03:02.000 And that's a comfortable rhythm by somebody in a forum that you copied because you wanted some feature. 03:02.000 --> 03:11.000 So it's not very maintainable. What about the OS? So if you run your 3D printer in Kubernetes, you get the same OS that you have for any scenarios. 03:11.000 --> 03:14.000 Do you know how to maintain that? Do you know how to troubleshoot that? 03:14.000 --> 03:24.000 In the Raspberry Pi, you probably have some sort of deviant in there with very special snowflakes settings that if you break, you're going to have a tough time. 03:25.000 --> 03:32.000 Okay, backups. Not super interesting for three printers because, as we're going to talk, the important thing which is the config file is going to be somewhere else. 03:32.000 --> 03:39.000 But if you wanted to backup your gcode files for, I don't know whatever reason, you hopefully have a backup controller that will take care for you. 03:39.000 --> 03:51.000 With that, with the Raspberry Pi, you probably took an image of that sticker, like two years ago, or something, and I don't know who, how the setup has diverged from that from that image. 03:51.000 --> 03:57.000 Versioning. I think this is like the biggest selling point. If I haven't commissioned by now, this will happen to me. 03:57.000 --> 04:05.000 3D printer configs are finicky. You try a lot of stuff, you know, increase this parameter, enable this experimental feature, whatever. 04:05.000 --> 04:17.000 That is tricky and error prone. So if you run this on Kubernetes, and you have a same Kubernetes data set up with gdops and whatnot, your 3D printer configuration is on Kubernetes. 04:18.000 --> 04:24.000 That means that you get it, get versions for free, and you don't have to do anything weird, you don't have to set that adok. 04:24.000 --> 04:29.000 As opposed to, you know, files that you copy over, or now we're adding more and more suffocates to it. 04:29.000 --> 04:33.000 Roll out automatic, no WCP, no nothing, Kubernetes take care. 04:33.000 --> 04:41.000 Upgrades, my big other selling point. You upgrade the 3D printer software that you're using, octoprient, clipper, this will be able to clipper. 04:41.000 --> 04:50.000 Something breaks, oh no, what do I do? You pray, you pray, you pray, you raim it, and probably lose whatever conflicts that you have done. 04:50.000 --> 04:57.000 With Kubernetes, you have, you have it in there, you just roll back to the previous container version, so that's, that's kind of nice. 04:57.000 --> 05:02.000 Okay, who has acidity printer? Probably, you have acidity time. 05:02.000 --> 05:10.000 Okay, then, do you know how this works? You get a model, you slice the model, and you get something that looks like on your left. 05:10.000 --> 05:17.000 That's called Gico, that tells the printer move here, then here, and extrude this amount of plastic, and on the way. 05:17.000 --> 05:26.000 Something in your printer will translate that to, like, pulses, electricity pulses, up and down, up and down, that will write the steppers. 05:26.000 --> 05:35.000 And, uh, turns out that, that is pretty hard to do. There is a lot of things that you can do between left and right to make your printer print better. 05:35.000 --> 05:42.000 So, at some point, somebody clever people figure out, okay, what if we don't do this inside the printer? 05:42.000 --> 05:46.000 Because that's, like, quite a lot of number crunching, and those things, like, under power. 05:46.000 --> 05:52.000 What if we put a computer in the middle? What if we have all this translation, don't buy a computer? 05:52.000 --> 06:00.000 And at this point, it's like, okay, we got it. This, this is a container. Let's, let's put it inside the container. 06:00.000 --> 06:05.000 So, how does this set up work? So, we'll have our Kubernetes cluster. 06:05.000 --> 06:11.000 We have this, on the top, this, I mean, if you have a theory printer, you probably want a webcam. 06:11.000 --> 06:17.000 So, we have a very nice application that's called go to RTC for that. So, let's put that on Kubernetes. 06:17.000 --> 06:23.000 We have, we probably want a fancy UI for your printer, that's what you saw at the beginning. 06:23.000 --> 06:30.000 And you see mainsail, there are others, that doesn't matter, that's like a completely static web application, obviously a container. 06:30.000 --> 06:36.000 Then, you got your 3D printer, like this, this server, we put in the middle. 06:36.000 --> 06:43.000 That's called, for, for what I like to use, is, is Clipper, and especially the host parties for Clippy. 06:43.000 --> 06:48.000 And there is, an oven for Clippy, that is called Moon Regal, I don't know what's called like that. 06:48.000 --> 06:51.000 But it's like puts, and rest API on top of Clipper. 06:51.000 --> 06:54.000 And that's, like, probably another container, we can container is that. 06:54.000 --> 07:01.000 We need to do, we need to give that USB access to the printer, but, okay, that's somewhat easy, right? 07:01.000 --> 07:07.000 And then, the decode files that we want to preserve for historical reasons for one of that. 07:07.000 --> 07:10.000 That can go into a volume, that's EC, Kubernetes, that's for you. 07:10.000 --> 07:16.000 And the printer config, in Clipper, that's called, the printer does CFG file. 07:16.000 --> 07:23.000 That is going to be, obviously, in a config map, that way it is version, and we can track it from, from Git and one of them. 07:23.000 --> 07:26.000 So, how can you try it? 07:26.000 --> 07:31.000 If I have, hopefully, convinced you, I have created this thing, it's called Cube Clipper. 07:31.000 --> 07:34.000 It's just a hunter, it's nothing fancy. 07:34.000 --> 07:42.000 And it is powered by the images created by this fella named Markus, who created most of the images and using, 07:42.000 --> 07:45.000 that is in that, on that second repo. 07:46.000 --> 07:52.000 So, before we jump to see if the printer has got fire or not, this is cool. 07:52.000 --> 07:54.000 I've been running this for three years. 07:54.000 --> 07:57.000 Like at this point, it has worked extremely well for me. 07:57.000 --> 08:00.000 We can show some, some manifest and some conflicts and whatnot. 08:00.000 --> 08:04.000 But I would like to pitch you an idea, maybe, if you are interested. 08:04.000 --> 08:07.000 I will, I think it will be nice to take this to the next level. 08:07.000 --> 08:12.000 I think it will be cool if we move from the hunter thingy, we make this an operator. 08:12.000 --> 08:15.000 I think it will be cool to have a custom resource that is a printer. 08:15.000 --> 08:17.000 And we can't have status in it, right? 08:17.000 --> 08:18.000 Is the thing printing? 08:18.000 --> 08:19.000 Is it not printing? 08:19.000 --> 08:20.000 Is it island? 08:20.000 --> 08:21.000 Is it skating? 08:21.000 --> 08:22.000 Like, why not? 08:22.000 --> 08:23.000 I think that will be quite cool. 08:23.000 --> 08:28.000 Because, for example, we call the use that to simply, seamlessly upgrade the printer. 08:28.000 --> 08:32.000 If you try to do that while the printer is printing, it's not going to end up great. 08:32.000 --> 08:34.000 For your printer, we'll be fine. 08:34.000 --> 08:35.000 Your print will not. 08:35.000 --> 08:37.000 So, Kubernetes to provision some of several of it as well. 08:37.000 --> 08:39.000 Maybe it is, well, maybe toss on the fan of passwords. 08:39.000 --> 08:43.000 Maybe some promissues, scripts, conflicts, or whatnot. 08:43.000 --> 08:48.000 And, I don't know, if this kind of works and people feel very, very bold about it. 08:48.000 --> 08:51.000 Maybe we can make the thing flash the printer. 08:51.000 --> 08:53.000 I think that will be nice. 08:53.000 --> 08:55.000 And it will be extra nice. 08:55.000 --> 08:56.000 And I'm dreaming at this point. 08:56.000 --> 09:01.000 But we will move this slicer to a server and have the way you, I think that will be nice. 09:01.000 --> 09:04.000 But I'm probably, I'm probably going to help this. 09:04.000 --> 09:07.000 So, I don't think I have more slides. 09:07.000 --> 09:08.000 This is my mail address. 09:08.000 --> 09:10.000 If you want to chat about this, it's very interesting. 09:10.000 --> 09:12.000 I do not try to join me. 09:12.000 --> 09:13.000 I make this a reality. 09:13.000 --> 09:15.000 Please, please get in touch. 09:15.000 --> 09:17.000 The email address is also on my website. 09:17.000 --> 09:19.000 And that's all. 09:19.000 --> 09:20.000 Thank you. 09:20.000 --> 09:30.000 I think we'd have, like, 40 seconds for questions. 09:30.000 --> 09:36.000 No, I think questions can take them outside. 09:36.000 --> 09:37.000 It's cool. 09:37.000 --> 09:38.000 Okay. 09:38.000 --> 09:39.000 Thank you very much again. 09:50.000 --> 09:51.000 Thank you.
