1 00:00:04,290 --> 00:00:09,300 Before going on, I need to perform some cleanup of my doggerel gross up because I have some cached 2 00:00:09,330 --> 00:00:11,540 images and some containers that well stopped. 3 00:00:11,970 --> 00:00:13,480 If you have cleaned it up. 4 00:00:13,500 --> 00:00:15,250 Feel free to skip this lecture and move on. 5 00:00:15,250 --> 00:00:15,990 Want the next one? 6 00:00:16,470 --> 00:00:16,810 All right. 7 00:00:17,250 --> 00:00:20,970 Let me at least the containers here that where I stopped Dakara. 8 00:00:21,640 --> 00:00:21,910 Yes. 9 00:00:22,090 --> 00:00:25,980 There's a and here I see bunch of stop the containers. 10 00:00:26,250 --> 00:00:32,650 And in order to remove all stop containers, I could use command dock from container Bruun. 11 00:00:33,330 --> 00:00:35,540 There is no short version of this command. 12 00:00:35,610 --> 00:00:39,540 That's why I'm using Container Management Command along with Spruill. 13 00:00:39,600 --> 00:00:40,320 Self-command. 14 00:00:41,850 --> 00:00:45,870 Diaby, yes, here and all stopped containerize where are deleted? 15 00:00:46,390 --> 00:00:51,880 And now if all this container was using same comment, Dr. Pierce, there's a I will not see any containers 16 00:00:51,940 --> 00:00:52,420 on the list. 17 00:00:52,960 --> 00:00:53,240 Great. 18 00:00:53,620 --> 00:00:54,090 Let me know. 19 00:00:54,090 --> 00:00:58,120 At least all images that I held before pulled from Docker Hub for that. 20 00:00:58,180 --> 00:00:59,410 I could use a short comment. 21 00:00:59,470 --> 00:01:00,450 Docker images. 22 00:01:01,000 --> 00:01:06,690 And here was a long list of images that I have used before in the previous longer practice chapter. 23 00:01:07,000 --> 00:01:10,490 And I see such images as my sequel, WordPress, sir. 24 00:01:10,690 --> 00:01:12,460 HD, DVD or Rightest and so on. 25 00:01:12,940 --> 00:01:17,950 At the moment those images are not used and there are no containers created from those images. 26 00:01:18,310 --> 00:01:24,340 This way I am able to safely baroon those images and for that I could use Docker image. 27 00:01:24,340 --> 00:01:25,060 Broon Command. 28 00:01:25,510 --> 00:01:26,780 Let me throw that list. 29 00:01:26,920 --> 00:01:27,520 All commands. 30 00:01:27,620 --> 00:01:31,060 Subcommanders of Dogra Image Management Command Docker image. 31 00:01:31,090 --> 00:01:31,870 That does help. 32 00:01:32,650 --> 00:01:38,230 And here is this list of sub commands that you are able to use along with Image Management Command. 33 00:01:38,560 --> 00:01:39,950 And here was Broon Command. 34 00:01:40,030 --> 00:01:46,330 And with help of this command, you are able to remove unused images in which is considered unused. 35 00:01:46,360 --> 00:01:51,350 When there are no Iran in all stopped containers that were created from this image. 36 00:01:52,080 --> 00:01:52,360 Great. 37 00:01:52,600 --> 00:01:53,050 Let me know. 38 00:01:53,050 --> 00:01:58,540 List the all possible options for Broon command docker image Baroon. 39 00:01:59,080 --> 00:01:59,800 This does help. 40 00:02:00,980 --> 00:02:02,480 And here are some options. 41 00:02:02,870 --> 00:02:08,930 And notice that with Dash a option or there's this all this long version of this short comment, you 42 00:02:08,930 --> 00:02:13,060 are able to remove all unused images, not just them being ones. 43 00:02:13,670 --> 00:02:20,960 It means that just with Docker image, Broon Command Doga will remove only so-called Vanderlyn images 44 00:02:21,620 --> 00:02:27,260 and image is considered downlink when there is no corresponding version of this image. 45 00:02:27,350 --> 00:02:31,790 A Docker hub, for example, when you have pulled specific image from Docker Hub. 46 00:02:32,000 --> 00:02:35,300 But afterwards such image was removed from dogor hub. 47 00:02:35,540 --> 00:02:37,490 But it remains in your local cache. 48 00:02:37,850 --> 00:02:40,190 This image is called dentin image. 49 00:02:40,610 --> 00:02:42,920 But I want to remove all unused images. 50 00:02:43,130 --> 00:02:44,990 And that's why I need to add this. 51 00:02:45,080 --> 00:02:47,090 A option to Docker image. 52 00:02:47,150 --> 00:02:47,870 Bruun Command. 53 00:02:48,410 --> 00:02:48,940 Let's do that. 54 00:02:49,370 --> 00:02:50,870 Docker Image. 55 00:02:51,140 --> 00:02:52,640 Bruun Desh A. 56 00:02:53,690 --> 00:02:54,110 Yes. 57 00:02:54,830 --> 00:03:01,220 Notice that this will remove all images without at least one container associated to them at the moment. 58 00:03:01,250 --> 00:03:03,770 I don't have any containers running or stopped. 59 00:03:04,260 --> 00:03:04,460 Great. 60 00:03:04,550 --> 00:03:04,910 Let's press. 61 00:03:04,940 --> 00:03:05,590 And our hero. 62 00:03:06,660 --> 00:03:13,320 I need to get out because the doctor is a to several gigabytes of images and finally images are deleted. 63 00:03:13,770 --> 00:03:19,070 And in this outward, I see a long list of looks like deleted the SHA 256. 64 00:03:19,140 --> 00:03:22,560 And then comes a list of hexadecimal characters. 65 00:03:22,860 --> 00:03:27,100 And here in this output, I see a long list of such clocks. 66 00:03:27,720 --> 00:03:32,970 Also, I see such logs as untagged nold latest or untracked nold. 67 00:03:33,050 --> 00:03:36,580 Add the shadow on them two to six and then comes again showerheads. 68 00:03:37,080 --> 00:03:41,530 And again, this list is much longer than then amount of images. 69 00:03:41,610 --> 00:03:43,570 I have used on this DOKO machine. 70 00:03:44,190 --> 00:03:50,790 And the reason for that is that basically every image consists of multiple file system layers. 71 00:03:51,270 --> 00:03:55,240 And that's why Dogra has the removed correspondant filesystem layer. 72 00:03:55,440 --> 00:03:57,090 Instead of just removing images. 73 00:03:57,420 --> 00:04:00,320 That's why in this Solok output, I see multiple lines. 74 00:04:00,630 --> 00:04:04,250 Because every image you may have multiple afast layers. 75 00:04:05,310 --> 00:04:08,400 For example, this Beezy books image had two layers. 76 00:04:08,430 --> 00:04:11,640 And that's why here I see those two deleted lines. 77 00:04:12,390 --> 00:04:14,670 I'll buy an image has only one. 78 00:04:14,730 --> 00:04:17,870 That's why here I see on this one deleted line. 79 00:04:18,450 --> 00:04:19,560 But no worries. 80 00:04:19,620 --> 00:04:21,690 We'll talk about all those details a bit later. 81 00:04:21,959 --> 00:04:27,210 For now, you need to understand that I have successfully deleted all images that were stored in my 82 00:04:27,270 --> 00:04:28,050 local cache. 83 00:04:28,500 --> 00:04:31,680 And now if I enter Dockum image, just comment. 84 00:04:32,240 --> 00:04:33,090 I'll see nothing. 85 00:04:33,240 --> 00:04:37,470 There are no images in my local cache and we are able to go on next. 86 00:04:37,530 --> 00:04:38,610 I'll start from scratch. 87 00:04:38,700 --> 00:04:43,740 And the Lord, where he throws the most simple hello world container and explain what happens under 88 00:04:43,740 --> 00:04:44,070 the hood. 89 00:04:44,310 --> 00:04:46,900 And what does the structure of that image that will download. 90 00:04:47,250 --> 00:04:48,360 I'll see you in the next lecture. 91 00:04:48,540 --> 00:04:48,640 Right.
