WEBVTT 00:00.120 --> 00:04.680 So whether you're on a mac or on a PC, this is what Docker Desktop should look like when it comes up 00:04.720 --> 00:08.480 like a window like this, which is giving you your information. 00:08.480 --> 00:15.440 And on the left here you'll see some navigation that containers is telling you all of these boxes running 00:15.440 --> 00:19.760 on your box in their own little world, their own delicate, dedicated world. 00:20.200 --> 00:23.640 An image is like a blueprint for making a container. 00:23.640 --> 00:25.640 It's a description of a container. 00:25.640 --> 00:27.920 If you're a Docker user, you'll have a gazillion of these. 00:27.960 --> 00:32.560 Probably I did too, but I just deleted them all so that we'd come up empty like this. 00:32.760 --> 00:37.920 And you basically can can pull down an image that's, that's, that's stored in a, in a remote hub 00:37.960 --> 00:43.040 and bring that down so that you can have like running on your box. 00:43.240 --> 00:49.040 Uh, and volumes are like disk drives, like little internal disk drives that are set up that are ring 00:49.080 --> 00:52.120 fenced for your Docker container. 00:52.120 --> 00:57.480 And I've got some old nonsense here that you can safely ignore, but we're about to create a volume 00:57.480 --> 00:58.560 for Nan. 00:58.600 --> 01:00.200 That's going to be the next thing we're going to do. 01:00.670 --> 01:03.390 Uh, and, uh, the rest of this, you can you can safely ignore. 01:03.430 --> 01:05.950 We're only going to really look at containers and volumes, to be honest. 01:05.950 --> 01:07.270 That's where we will be. 01:07.310 --> 01:14.230 And the next thing we're going to do is create a volume for like a disk that can be used within your 01:14.230 --> 01:14.630 disk. 01:14.710 --> 01:17.910 Uh, that will use for running on your computer. 01:17.950 --> 01:25.710 So back here on the docs website, you'll see that it tells you how to start right here. 01:25.910 --> 01:29.270 And basically it's got this bit of code right here. 01:29.270 --> 01:32.670 And I'm just going to take this first line Docker volume. 01:32.670 --> 01:35.990 Create any data whether you're on a mac or a PC. 01:36.110 --> 01:36.910 Same thing. 01:37.030 --> 01:41.510 Copy that into your clipboard because we're going to run it and we're going to run it in this terminal 01:41.510 --> 01:41.950 thing. 01:41.990 --> 01:47.670 And so if you're if you're using a PC, you now want to bring up that PowerShell thing I showed you. 01:47.910 --> 01:49.230 Uh, apologies. 01:49.230 --> 01:52.230 The technical people here, they're like, oh my goodness, I know what to do. 01:52.350 --> 01:55.630 Uh, but for people new to it, it can be, uh, weird the first time. 01:55.630 --> 02:01.430 And for Mac, people remember it's it's command space type terminal Spell it right. 02:01.470 --> 02:02.910 Terminal. 02:02.950 --> 02:05.030 You can't see what I'm doing here, but I'm messing around. 02:05.070 --> 02:05.590 Terminal. 02:05.630 --> 02:06.150 There we go. 02:06.150 --> 02:07.310 And then here it is. 02:07.310 --> 02:08.310 Here's the terminal. 02:08.310 --> 02:09.710 I'm going to paste that in. 02:09.750 --> 02:11.230 I'm going to press enter. 02:11.230 --> 02:14.670 And this is telling Docker to create that volume. 02:14.670 --> 02:15.750 And it's done. 02:16.670 --> 02:21.670 If it didn't work if it didn't recognize the command docker first thing to do is to restart your computer, 02:21.670 --> 02:22.830 launch Docker again. 02:22.870 --> 02:26.030 Maybe some system path variable wasn't set. 02:26.550 --> 02:32.950 If you got some error on PC that was about not having permissions to run a script, then just google 02:32.950 --> 02:33.510 that error. 02:33.510 --> 02:36.790 It's the super common setting that you might have to another command. 02:36.790 --> 02:38.030 You might have to run on your PC. 02:38.190 --> 02:44.350 That gives you the authority to be allowed to run a command like this, but that that should all be 02:44.350 --> 02:45.030 relatively easy. 02:45.070 --> 02:48.790 We should now have a volume called data. 02:49.230 --> 02:50.750 Well, let's go and check that out back. 02:50.750 --> 02:54.190 We need to go to Docker Desktop to see see how that looks. 02:54.190 --> 02:55.390 Here's Docker desktop. 02:55.550 --> 02:59.030 Let's go to volumes just here and check that out. 02:59.030 --> 03:03.260 There's a new Nan data volume that has appeared and it has no bytes. 03:03.260 --> 03:07.820 It's an empty volume that's set up and ready for N810 to be on it. 03:07.820 --> 03:09.580 And we still have no containers. 03:09.780 --> 03:10.420 Okay. 03:10.460 --> 03:14.220 Next step is to actually run N810 and that's all it takes. 03:14.260 --> 03:17.780 We're just going to run a command that's going to kick off N810. 03:17.820 --> 03:19.580 So here we are back in the Nan docs. 03:19.580 --> 03:24.500 And this part here is the command remaining to be run which is actually going to do it all. 03:24.700 --> 03:27.220 Uh and it looks a bit intimidating the first time you see it. 03:27.220 --> 03:29.540 There's a few things here, but never fear. 03:29.780 --> 03:36.820 Uh, I do believe that on a PC, we need to edit this a bit, remove these slashes, and just have it 03:36.820 --> 03:38.220 all on one line. 03:38.220 --> 03:38.500 So? 03:38.500 --> 03:40.540 So that it's just everything comes after another. 03:40.540 --> 03:45.100 And I'm going to put that in the course resources just as it is, so that you can just copy and paste 03:45.100 --> 03:45.980 from there if you wish. 03:45.980 --> 03:50.300 Or you can just delete, uh, these, these backslashes and just make sure there's no empty line. 03:50.300 --> 03:51.820 You just have everything on one line. 03:52.220 --> 03:57.500 Uh, and the other thing is that it wants us to put in our time zone instead of this green stuff here. 03:57.700 --> 04:01.690 And the place you find that is in this link here, your time zone click there. 04:01.690 --> 04:03.490 It comes up with a bunch of time zones. 04:03.810 --> 04:08.770 As of right now I am currently in in London so I would have to come down. 04:08.770 --> 04:09.850 I believe it's Europe. 04:10.250 --> 04:12.010 London would be my time zone. 04:12.170 --> 04:14.250 Uh, that's going to be a lot of scrolling. 04:14.370 --> 04:15.770 Uh, somewhere in here would be. 04:15.770 --> 04:16.210 Here we go. 04:16.210 --> 04:17.130 We're getting close. 04:17.130 --> 04:18.170 Here's Europe, London. 04:18.170 --> 04:19.410 That's where I am right now. 04:19.570 --> 04:21.170 But, uh, you might be somewhere else. 04:21.210 --> 04:25.290 You should pick wherever you are and make sure that that is what you include here. 04:25.490 --> 04:27.330 Uh, and, uh, but for now. 04:27.330 --> 04:29.130 So I'm going to take all of this. 04:29.130 --> 04:29.530 Copy this. 04:29.570 --> 04:31.490 We've already run this this create part. 04:31.530 --> 04:36.290 We're going to run this command now in a terminal on a mac or in PowerShell on a PC. 04:36.530 --> 04:37.170 Okay. 04:37.450 --> 04:41.650 So, uh, back we go to, to the terminal again. 04:41.810 --> 04:42.930 Terminal. 04:43.370 --> 04:44.690 Uh, here it is. 04:44.970 --> 04:48.770 So I'm going to start just by by pasting this in there. 04:48.970 --> 04:55.850 Now I'm going to go back and I'm going to replace everything with what I care about. 04:55.850 --> 04:58.370 I could also just press the up button rather than going through. 04:58.490 --> 05:02.090 So for this first time zone here I'm going to delete that. 05:02.090 --> 05:05.410 And I'm going to type Europe slash London. 05:06.170 --> 05:09.010 And for this time zone here I'm going to delete that. 05:09.010 --> 05:13.290 And I'm going to put Europe slash London. 05:14.690 --> 05:21.410 If you're doing this on a PC then I recommend you come to each of these and you put it all on one line 05:21.410 --> 05:25.130 like that, just just to remove these backslashes. 05:25.130 --> 05:30.250 I think that that doesn't work on on all versions of the PC and bring it all onto one line. 05:30.250 --> 05:38.490 And of course, this will also work just fine on a mac as well, all in one line like this and like 05:38.610 --> 05:39.130 this. 05:40.890 --> 05:43.610 And you're like, come on. 05:44.050 --> 05:52.730 Uh, I know you get the idea, but I now I've started, I will finish up and this to there we go. 05:52.770 --> 05:56.210 Minus v okay. 05:56.490 --> 06:02.120 And now now that I finally put you through that, let me just explain what this crazy command is actually 06:02.120 --> 06:02.400 doing. 06:02.440 --> 06:04.120 I should also make this a bit bigger. 06:04.120 --> 06:04.840 Of course. 06:05.040 --> 06:05.760 Here we go. 06:05.800 --> 06:06.320 There we go. 06:06.360 --> 06:07.400 That's nice and big. 06:07.400 --> 06:09.480 I'm sorry if you've been squinting in there. 06:09.520 --> 06:10.920 Now you can actually see what I've done. 06:10.920 --> 06:12.320 I've put it all on one line. 06:12.680 --> 06:15.160 Uh, so what is this about? 06:15.160 --> 06:15.480 So. 06:15.520 --> 06:22.560 So the command begins Docker run, and that means it's instruction to Docker, the, the platform that's 06:22.560 --> 06:25.360 running on your computer that tells it that there's something we want to do. 06:25.400 --> 06:26.840 We want to run something. 06:27.240 --> 06:32.040 Everything that comes after that is a bunch of different flags, giving it some special things about 06:32.040 --> 06:32.280 it. 06:32.280 --> 06:36.600 So you can see there's a flag called name that's saying, hey, I want to call this thing I'm about 06:36.600 --> 06:37.000 to do. 06:37.040 --> 06:38.600 I want to call it N810. 06:39.000 --> 06:42.840 What we're actually about to do is we're about to start a Docker container. 06:42.840 --> 06:48.600 We're about to start one of these, uh, these boxes within our box, these computers inside our computer, 06:48.600 --> 06:50.600 and we're going to call it N810. 06:50.960 --> 06:55.600 And there's a few other for the technical people, of course, you may well recognize things about this. 06:55.600 --> 06:59.550 That minus p flag is saying, hey, look for this box within a box. 06:59.550 --> 07:05.110 I want to take the port, the network port number five, six, seven, eight, and I want to map that 07:05.110 --> 07:10.710 to port 5678 on my host computer so that if I'm on my host and I go to five, six, seven, eight, 07:10.750 --> 07:15.950 it's going to go into the actual box within a box, the container and look on that port. 07:15.950 --> 07:17.630 Those two ports will be connected. 07:17.630 --> 07:20.910 And that's a very common trick with Docker containers. 07:21.590 --> 07:26.670 The the other things there, the dash e these are setting environment variables. 07:26.670 --> 07:31.710 So we're setting a bunch of environment variables about things like the time zone about some some ones 07:31.710 --> 07:36.790 that Nan recommends we have about enforced settings file permissions and runners enabled. 07:37.230 --> 07:41.910 And then uh there's this minus V which is about volumes. 07:42.070 --> 07:44.590 And again only technical people need to worry about this. 07:44.590 --> 07:48.070 But we're saying hey, we've got a volume called Nan Data. 07:48.070 --> 07:51.550 That's the volume that we just set up inside the container. 07:51.670 --> 08:00.350 When you ever go to slash home node, I want that to be actually going into this volume, the separate 08:00.350 --> 08:05.390 disc that we've, that we've ring fenced for this purpose so that it's as if there's like a persistent 08:05.390 --> 08:08.550 disk that's always pointing at any data. 08:08.950 --> 08:10.790 So that's those are all the flags. 08:10.790 --> 08:19.350 And finally, at the end of it all is the name of a docker, a Docker image, a description, a blueprint 08:19.350 --> 08:23.310 for a Docker container that is described Docker. 08:25.070 --> 08:31.830 So this is an, uh, website where they have a particular URL that you can see here. 08:31.830 --> 08:38.150 And that serves up a Docker image, a description of what a container should look like with all the 08:38.150 --> 08:39.590 details of that container. 08:39.590 --> 08:40.910 And this is the key part. 08:40.950 --> 08:42.670 This is the essential part. 08:42.830 --> 08:46.070 This is where we are saying we want you to please Docker. 08:46.070 --> 08:51.630 We want you to look this up, find this this Docker image, this description of what a container should 08:51.630 --> 08:55.910 look like, and then build a container on my machine to do it. 08:56.190 --> 08:57.870 That is what this command does.
