1
00:00:00,350 --> 00:00:01,370
‫So now let's go ahead

2
00:00:01,370 --> 00:00:04,800
‫and create our first records in Route 53.

3
00:00:04,800 --> 00:00:06,910
‫So I'm going to go into my hosted zone,

4
00:00:06,910 --> 00:00:09,960
‫and in there I'm going to create some simple records.

5
00:00:09,960 --> 00:00:10,793
‫So let's have a look.

6
00:00:10,793 --> 00:00:13,660
‫We're going to create a record by clicking on here.

7
00:00:13,660 --> 00:00:15,990
‫And in here, I can just have a record name.

8
00:00:15,990 --> 00:00:19,720
‫So we want it to be test.stephanetheteacher.com.

9
00:00:19,720 --> 00:00:21,240
‫But you can enter anything you want here.

10
00:00:21,240 --> 00:00:23,730
‫This is how you would create your domain names.

11
00:00:23,730 --> 00:00:25,920
‫Now you have to specify the record type.

12
00:00:25,920 --> 00:00:28,150
‫So you can see there's a lot of record types in here,

13
00:00:28,150 --> 00:00:29,360
‫but for now we'll keep it simple.

14
00:00:29,360 --> 00:00:31,120
‫We'll keep it as an A record.

15
00:00:31,120 --> 00:00:34,000
‫And which is to route an IPv4 address

16
00:00:34,000 --> 00:00:36,870
‫into a domain name, to an IPv4 address.

17
00:00:36,870 --> 00:00:38,530
‫So the answer is going to be

18
00:00:38,530 --> 00:00:42,100
‫value is 1, 1, dot, 2, 2, dot, 3, 3, dot, four four.

19
00:00:42,100 --> 00:00:44,150
‫Which is just a value we want to have,

20
00:00:44,150 --> 00:00:46,760
‫and this is not a domain, an IP we own right now,

21
00:00:46,760 --> 00:00:48,720
‫but just to show you just a random value.

22
00:00:48,720 --> 00:00:52,690
‫Later on, we'll be routing to a real institute instance.

23
00:00:52,690 --> 00:00:53,523
‫Okay.

24
00:00:53,523 --> 00:00:54,356
‫TTL is time to live.

25
00:00:54,356 --> 00:00:55,860
‫We'll leave it as 300 seconds right now.

26
00:00:55,860 --> 00:00:57,220
‫And the routing policy will

27
00:00:57,220 --> 00:00:59,900
‫routing policy will have a look at it later on as well.

28
00:00:59,900 --> 00:01:02,690
‫We'll leave everything as simple routing. Okay.

29
00:01:02,690 --> 00:01:04,740
‫So let's go ahead and create this record.

30
00:01:06,240 --> 00:01:08,920
‫And now my record has been successfully created.

31
00:01:08,920 --> 00:01:12,860
‫So the idea is that if I go to test.stephanetheteacher.com,

32
00:01:12,860 --> 00:01:16,040
‫it is going to ask my host zone.

33
00:01:16,040 --> 00:01:18,060
‫What is the value of that? And those isn't going to say,

34
00:01:18,060 --> 00:01:21,083
‫well, the value of it is 1, 1, dot, 2, 2, dot,

35
00:01:21,083 --> 00:01:22,270
‫3, 3, dot, 4, 4.

36
00:01:22,270 --> 00:01:24,960
‫So if you try it to do it with a web browser,

37
00:01:24,960 --> 00:01:27,440
‫so if you take your browser and you open it

38
00:01:27,440 --> 00:01:28,940
‫and you press enter,

39
00:01:28,940 --> 00:01:30,850
‫and it's not going to show you many things,

40
00:01:30,850 --> 00:01:34,626
‫because right now we don't have 11.22.33.44,

41
00:01:34,626 --> 00:01:38,110
‫there's probably no server that exists with that IP as well.

42
00:01:38,110 --> 00:01:40,510
‫And if I try to just access this URL,

43
00:01:40,510 --> 00:01:42,040
‫it doesn't work. Okay.

44
00:01:42,040 --> 00:01:44,830
‫So what we know is what is going on behind the scenes.

45
00:01:44,830 --> 00:01:46,910
‫And so for this, we're going to type some command lines.

46
00:01:46,910 --> 00:01:48,240
‫Now you can be using your command line

47
00:01:48,240 --> 00:01:50,550
‫on your windows laptop, or your Mac,

48
00:01:50,550 --> 00:01:53,240
‫but because I want everyone to follow the same way as me,

49
00:01:53,240 --> 00:01:54,823
‫I'm going to show you how to do it using

50
00:01:54,823 --> 00:01:57,270
‫the CloudTrail environments in AWS.

51
00:01:57,270 --> 00:01:59,339
‫So let me open the management console,

52
00:01:59,339 --> 00:02:03,020
‫and then I'm going to click here to open cloud shell and

53
00:02:03,020 --> 00:02:06,680
‫cloud shell is going to allow me to do some commands using

54
00:02:06,680 --> 00:02:09,280
‫a standard Linux command line interface. Okay.

55
00:02:09,280 --> 00:02:10,113
‫But this is fine,

56
00:02:10,113 --> 00:02:12,620
‫if you want to just do it with your own terminal on windows

57
00:02:12,620 --> 00:02:13,603
‫or on Mac.

58
00:02:14,480 --> 00:02:16,620
‫Okay. So my terminal is not ready.

59
00:02:16,620 --> 00:02:17,730
‫And if you're on windows,

60
00:02:17,730 --> 00:02:20,400
‫the NS lookup command is going to work. If you're on Mac,

61
00:02:20,400 --> 00:02:22,800
‫the dig command is going to work as well.

62
00:02:22,800 --> 00:02:24,630
‫But as you can see, these commands are not found

63
00:02:24,630 --> 00:02:26,060
‫on my cloud shell.

64
00:02:26,060 --> 00:02:26,970
‫So I need you to install them.

65
00:02:26,970 --> 00:02:30,360
‫So I do sudo yum, and then install

66
00:02:30,360 --> 00:02:32,450
‫minus Y and then bind

67
00:02:32,450 --> 00:02:34,540
‫minus utils.

68
00:02:34,540 --> 00:02:36,680
‫And it's going to install both VNS lookup

69
00:02:36,680 --> 00:02:39,360
‫and the dig commands on my cloud shell.

70
00:02:39,360 --> 00:02:41,160
‫So lets clear the screen.

71
00:02:41,160 --> 00:02:44,190
‫And now let's try to do NS lookup,

72
00:02:44,190 --> 00:02:48,940
‫test.stephanietheteacher.com.

73
00:02:48,940 --> 00:02:51,410
‫And as you can see, I get an answer,

74
00:02:51,410 --> 00:02:54,709
‫which is at test.stephanietheteacher.com,

75
00:02:54,709 --> 00:02:56,580
‫is going to 11.22.33.44,

76
00:02:56,580 --> 00:03:00,380
‫which is corresponding to what is happening right here,

77
00:03:00,380 --> 00:03:01,540
‫which is cool.

78
00:03:01,540 --> 00:03:04,180
‫And I presented like the dig command a little bit more

79
00:03:04,180 --> 00:03:05,700
‫because I'm more familiar with it,

80
00:03:05,700 --> 00:03:08,440
‫but if you type dig and then the URL that you have,

81
00:03:08,440 --> 00:03:09,820
‫okay.

82
00:03:09,820 --> 00:03:11,020
‫And press enter,

83
00:03:11,020 --> 00:03:14,940
‫you're going to see that and have the wrong commands.

84
00:03:14,940 --> 00:03:16,980
‫So stefantheteacher.com,

85
00:03:16,980 --> 00:03:19,780
‫so let's clear this screen and then retype the comments.

86
00:03:19,780 --> 00:03:20,750
‫Okay.

87
00:03:20,750 --> 00:03:21,950
‫Well here, we're going to see

88
00:03:21,950 --> 00:03:24,500
‫is that we have the answer section

89
00:03:24,500 --> 00:03:29,080
‫and says, test.stephanetheteacher.com is an a record,

90
00:03:29,080 --> 00:03:31,660
‫and this is the value of the record. So I like it better,

91
00:03:31,660 --> 00:03:34,400
‫better, because it shows you the TTL, as we'll see later on,

92
00:03:34,400 --> 00:03:36,905
‫and also shows you the a record,

93
00:03:36,905 --> 00:03:39,100
‫the fact that isn't a record. Okay.

94
00:03:39,100 --> 00:03:42,100
‫So we have created our first route 53 record,

95
00:03:42,100 --> 00:03:44,830
‫and we have been able to query it using a terminal,

96
00:03:44,830 --> 00:03:45,680
‫which is cool.

97
00:03:45,680 --> 00:03:49,016
‫Obviously loading it from a webpage doesn't work right now,

98
00:03:49,016 --> 00:03:51,720
‫but we'll see how we can do it later on

99
00:03:51,720 --> 00:03:53,330
‫when we have a real server.

100
00:03:53,330 --> 00:03:54,380
‫So I hope you liked this lecture

101
00:03:54,380 --> 00:03:56,330
‫and I will see you in the next lecture.
