1
00:00:01,310 --> 00:00:01,570
‫All right.

2
00:00:01,600 --> 00:00:07,790
‫So this week one of the topics I want to share before we get to the Q and A is about Windows Docker

3
00:00:07,790 --> 00:00:15,890
‫desktop and a new feature or a sort of enhancement on how Docker runs on Windows 10.

4
00:00:15,890 --> 00:00:21,050
‫So if you're a Windows user and you're running Windows 10 pro or enterprise you're lucky enough to be

5
00:00:21,050 --> 00:00:26,360
‫able to use Docker desktop which is basically the best way to run Docker on windows and it's a part

6
00:00:26,360 --> 00:00:28,330
‫of my courses I talk about it.

7
00:00:28,640 --> 00:00:34,010
‫Obviously if you have older versions of Windows you don't get to use Docker desktop but once you get

8
00:00:34,010 --> 00:00:39,190
‫to that Windows 10 pro one of the things is how to run the Windows containers.

9
00:00:39,200 --> 00:00:44,840
‫And we've talked about for years about Linux containers and you can run linux containers on Windows

10
00:00:44,930 --> 00:00:45,480
‫right.

11
00:00:45,590 --> 00:00:50,540
‫But a couple of years ago Microsoft came up with this new concept of Windows containers which was Windows

12
00:00:50,540 --> 00:00:55,970
‫binaries launching inside of Windows in a container.

13
00:00:55,970 --> 00:01:00,250
‫And technically what's happening in the background there is it's a Windows server kernel.

14
00:01:00,380 --> 00:01:06,170
‫So when you're on Windows 10 today by default and you start up a Windows Microsoft sequel server for

15
00:01:06,170 --> 00:01:13,790
‫example when you start that container it's going to spin up a small little core server or a Nanos server

16
00:01:13,790 --> 00:01:20,450
‫which are different types of windows server 2016 or 2019 that essentially are very small and it launches

17
00:01:20,450 --> 00:01:22,730
‫those and then launches your container in there.

18
00:01:22,850 --> 00:01:28,550
‫Right now that's great because you get to get you get that full server experience right you get the

19
00:01:28,550 --> 00:01:31,720
‫server kernel which is a little bit different than the windows 10 kernel.

20
00:01:31,880 --> 00:01:36,530
‫You get all the IRS features and things that you would get out of a server that are different than what

21
00:01:36,530 --> 00:01:44,050
‫you would get on Windows 10 however there is because this is known as hyper v isolation by the way that's

22
00:01:44,050 --> 00:01:49,910
‫called hyper v isolation and the negative of that is that it takes up more resources.

23
00:01:49,930 --> 00:01:50,200
‫Right.

24
00:01:50,200 --> 00:01:52,920
‫You've got to spin up the whole kernel for a new operating system.

25
00:01:52,930 --> 00:01:59,070
‫And ideally if you're just wanting to run a simple EMC maybe it's you know it's a dot net EMC maybe

26
00:01:59,070 --> 00:02:03,250
‫is just a command line you see it's not actually an eye as Web site or anything or if you just need

27
00:02:03,250 --> 00:02:07,930
‫to run some sort of background process in a container or Windows container you don't really need that

28
00:02:07,930 --> 00:02:10,810
‫full VM hyper v isolation.

29
00:02:10,810 --> 00:02:17,560
‫So now process isolation has finally come to Windows 10 and what this means is is when once you turn

30
00:02:17,560 --> 00:02:25,240
‫on a couple of things and enable it essentially Docker desktop will let you run a Windows binary on

31
00:02:25,240 --> 00:02:28,890
‫Windows 10 natively without ever having to spin up high hypervisor container.

32
00:02:28,930 --> 00:02:36,020
‫So there is this is actually the PR now in case you're curious on how this all happened.

33
00:02:36,110 --> 00:02:37,710
‫This is the pull request and get hub

34
00:02:41,130 --> 00:02:46,860
‫and that's sort of where the action happened with the feature being enabled and quite frankly I think

35
00:02:46,860 --> 00:02:52,050
‫this is ever gonna happen because out of the gate the Microsoft team was saying that they didn't really

36
00:02:52,050 --> 00:02:58,200
‫want containers to run natively on Windows 10 because the server kernel was so different that they needed

37
00:02:58,200 --> 00:03:02,490
‫the server kernel in order to have a similar experience no matter where you ran the container.

38
00:03:02,490 --> 00:03:04,580
‫Well that story has clearly changed now.

39
00:03:04,590 --> 00:03:08,230
‫So we have later late in 2018.

40
00:03:08,310 --> 00:03:14,670
‫This feature was added in the latest version of Docker desktop but you can check out Stefon one of the

41
00:03:14,670 --> 00:03:21,750
‫docker captains who's now actually a doctor employee one of his blog articles talks about how to start

42
00:03:21,750 --> 00:03:26,760
‫this and how to set it up and it's a few steps that I'm not going to go through live here because quite

43
00:03:26,760 --> 00:03:28,380
‫frankly he does a great job of it.

44
00:03:28,380 --> 00:03:33,900
‫You can just read his article and see the the Post and the example commands and get it running on your

45
00:03:33,900 --> 00:03:40,620
‫machine and basically at the end of it you will have been running Windows executable and Windows containers

46
00:03:40,620 --> 00:03:43,560
‫without ever having to start up a hyper v server.

47
00:03:43,560 --> 00:03:47,890
‫We don't yet have the ability to run Docker desktop because I know so many.

48
00:03:47,970 --> 00:03:49,820
‫Some of you were thinking this can I.

49
00:03:49,830 --> 00:03:55,560
‫Does that mean now can I run Docker desktop on Windows 10 home which doesn't have hyper v.

50
00:03:55,680 --> 00:03:59,910
‫That was a question we all immediately asked in the captain's chat to see whether or not we could get

51
00:03:59,910 --> 00:04:01,560
‫that going right now.

52
00:04:01,560 --> 00:04:03,090
‫That's still not possible.

53
00:04:03,390 --> 00:04:12,600
‫Desktop needs this all hyper v running in order to install and get that working but it is possible to

54
00:04:12,600 --> 00:04:16,260
‫do this process as prices lots of process isolation.

55
00:04:16,290 --> 00:04:18,990
‫It's hard to say without hyper v.

56
00:04:19,080 --> 00:04:27,300
‫So we're hoping we're maybe it's possible somewhere and this year maybe even that Docker desktop could

57
00:04:27,300 --> 00:04:35,100
‫possibly run only for process high school isolation on Windows containers on Windows 10 home.

58
00:04:35,100 --> 00:04:40,500
‫Now this this means that in that scenario if that were ever to work you still couldn't run Linux containers

59
00:04:40,740 --> 00:04:45,210
‫you still couldn't run Windows containers in hyper v isolation.

60
00:04:45,210 --> 00:04:49,620
‫So there's a lot of limitations here and it would really prevent you especially the fact you can't run

61
00:04:49,620 --> 00:04:51,720
‫Linux containers without hyper v.

62
00:04:51,780 --> 00:04:53,100
‫This would still really limit you.

63
00:04:53,220 --> 00:05:00,450
‫But it's it's sort of a crack a little bit of a crack in the limitation around requiring Windows 10

64
00:05:00,450 --> 00:05:03,590
‫pro in order to run Docker desktop anyway.

65
00:05:03,780 --> 00:05:05,040
‫We don't know if that's ever gonna happen.

66
00:05:05,040 --> 00:05:10,080
‫I mean you know these products are largely open source you know even Docker desktop though it's not

67
00:05:10,080 --> 00:05:11,120
‫completely open source.

68
00:05:11,130 --> 00:05:14,720
‫It depends entirely on the engine which is fully open source.

69
00:05:14,730 --> 00:05:20,760
‫So we really need open source contributions there or for it to be a real big priority for the Windows

70
00:05:20,760 --> 00:05:21,720
‫team.

71
00:05:21,720 --> 00:05:28,340
‫And you know having experience with the target market for docker docker desktop and docker enterprise.

72
00:05:28,590 --> 00:05:35,490
‫My feeling is that even though this might be possible on Windows 10 home that we won't see that anytime

73
00:05:35,490 --> 00:05:42,180
‫soon if it is forever because every company every enterprise is using Windows 10 pro or better.

74
00:05:42,180 --> 00:05:45,740
‫Usually enterprise licensing usually means they get Windows 10 enterprise.

75
00:05:45,770 --> 00:05:50,410
‫So the Windows 10 home market is probably more of a hobbyist market.

76
00:05:50,430 --> 00:05:56,370
‫And for me as a teacher I know that my students have witnessed in home at home and then they might have

77
00:05:56,370 --> 00:06:01,650
‫pro at work and there probably might be using their home machine right to learn Docker.

78
00:06:01,680 --> 00:06:06,870
‫So it's it's a shame because even though we're professionals we would still sometimes use home at home.

79
00:06:07,110 --> 00:06:12,290
‫But I got this feeling that it's not going to be a top priority with the windows Docker desktop team

80
00:06:12,330 --> 00:06:13,120
‫but we'll see.

81
00:06:13,140 --> 00:06:13,610
‫Right.

82
00:06:13,620 --> 00:06:14,940
‫I don't get your hopes up.

83
00:06:14,970 --> 00:06:17,550
‫I don't have any insider information or anything.

84
00:06:17,550 --> 00:06:21,990
‫I just know that this stuff is one complicated and it can be hard to get right.

85
00:06:22,050 --> 00:06:26,150
‫And then for stuff like this it has to be a big priority to happen quickly.

86
00:06:26,160 --> 00:06:31,590
‫So it's not probably something I would've guessed that the big enterprises in the world are all asking

87
00:06:31,590 --> 00:06:33,290
‫for Windows 10 home compatibility.

88
00:06:33,320 --> 00:06:35,040
‫So but you never know.

89
00:06:35,490 --> 00:06:36,240
‫So check that out.

90
00:06:36,240 --> 00:06:41,190
‫Try that let me know in the comments of course you know zooming out a tweet or if you're in the docker

91
00:06:41,190 --> 00:06:46,200
‫or mastery slack let me know there if you can get this working because it's pretty great.

92
00:06:46,200 --> 00:06:50,430
‫And I think it'll save you some resources and make it much faster to spin up and spin down containers

93
00:06:50,460 --> 00:06:51,780
‫if you're working on Windows containers.
