1
00:00:00,640 --> 00:00:03,310
Okay, so let's go into the ECS console,

2
00:00:03,310 --> 00:00:06,810
to start using the Elastic Container Service.

3
00:00:06,810 --> 00:00:09,440
So what I'm going to do is going to get started,

4
00:00:09,440 --> 00:00:12,040
and then we have to create our first cluster.

5
00:00:12,040 --> 00:00:13,560
So let's create a cluster,

6
00:00:13,560 --> 00:00:15,960
and this is a cluster we're going to give so name,

7
00:00:15,960 --> 00:00:16,793
so DemoCluster.

8
00:00:18,140 --> 00:00:19,840
We need to choose a VPC,

9
00:00:19,840 --> 00:00:20,880
which was the default VPC,

10
00:00:20,880 --> 00:00:22,120
as well as subnets,

11
00:00:22,120 --> 00:00:25,230
and this is where our resources are going to be deployed.

12
00:00:25,230 --> 00:00:29,040
Now we have different choices for the infrastructure.

13
00:00:29,040 --> 00:00:30,290
And as you can see,

14
00:00:30,290 --> 00:00:32,439
the number one that is selected by default

15
00:00:32,439 --> 00:00:34,590
is to use AWS Fargate.

16
00:00:34,590 --> 00:00:37,810
And Fargate is a serverless type of infrastructure

17
00:00:37,810 --> 00:00:39,620
in which you pay as you go,

18
00:00:39,620 --> 00:00:42,910
which is very helpful to run just instance,

19
00:00:42,910 --> 00:00:45,360
ECS tasks on the go.

20
00:00:45,360 --> 00:00:49,300
But if you wanted to manually provide Amazon EC2 instances,

21
00:00:49,300 --> 00:00:50,360
you could as well,

22
00:00:50,360 --> 00:00:53,330
and therefore you would need to create a new ASG,

23
00:00:53,330 --> 00:00:55,010
then you would need to choose an operating system,

24
00:00:55,010 --> 00:00:57,210
such as Amazon Linux two,

25
00:00:57,210 --> 00:00:58,980
an instance type, for example,

26
00:00:58,980 --> 00:01:02,290
your t2micro instances,

27
00:01:02,290 --> 00:01:03,930
your desired capacity for your ASG,

28
00:01:03,930 --> 00:01:05,050
so between zero and five,

29
00:01:05,050 --> 00:01:06,150
and zero and one.

30
00:01:06,150 --> 00:01:07,370
And then if you,

31
00:01:07,370 --> 00:01:10,350
if you want a SSH or not into them.

32
00:01:10,350 --> 00:01:13,500
So for the sake of this hands on,

33
00:01:13,500 --> 00:01:16,660
I can create one and show you what it's like.

34
00:01:16,660 --> 00:01:19,440
So I'll just choose zero and maximum five.

35
00:01:19,440 --> 00:01:22,140
And also we could specify external instances

36
00:01:22,140 --> 00:01:23,960
using ECS anywhere.

37
00:01:23,960 --> 00:01:25,560
This requires manual configuration,

38
00:01:25,560 --> 00:01:27,250
and need to register your servers

39
00:01:27,250 --> 00:01:28,850
maybe from on premises,

40
00:01:28,850 --> 00:01:31,680
onto your ECS cluster.

41
00:01:31,680 --> 00:01:33,820
So monitoring is optional,

42
00:01:33,820 --> 00:01:34,830
and tags are optional,

43
00:01:34,830 --> 00:01:36,410
so I'll leave it as is.

44
00:01:36,410 --> 00:01:39,180
So let's create this cluster.

45
00:01:39,180 --> 00:01:40,050
And in this cluster,

46
00:01:40,050 --> 00:01:41,220
as you remember,

47
00:01:41,220 --> 00:01:44,070
I've created both the Fargate launch type,

48
00:01:44,070 --> 00:01:45,820
which was selected by default,

49
00:01:45,820 --> 00:01:48,930
as well as the EC2 launch type.

50
00:01:48,930 --> 00:01:51,850
And to show you how the EC2 launch type works,

51
00:01:51,850 --> 00:01:54,713
if I go into the auto scaling groups,

52
00:01:55,940 --> 00:01:57,400
and then on the left hand side,

53
00:01:57,400 --> 00:01:59,943
I will click on auto scaling groups right here,

54
00:02:00,840 --> 00:02:01,673
and it's showing,

55
00:02:01,673 --> 00:02:02,610
as you can see,

56
00:02:02,610 --> 00:02:04,590
there was an auto scaling group created for me,

57
00:02:04,590 --> 00:02:07,420
called Infra ECS Cluster.

58
00:02:07,420 --> 00:02:09,160
And desired capacity is zero,

59
00:02:09,160 --> 00:02:10,120
main capacity, zero,

60
00:02:10,120 --> 00:02:11,560
maximum capacity, five.

61
00:02:11,560 --> 00:02:15,060
And this was created directly by my ECS cluster,

62
00:02:15,060 --> 00:02:17,110
and the creation is in progress.

63
00:02:17,110 --> 00:02:18,760
And what this cluster has,

64
00:02:18,760 --> 00:02:20,800
will have maybe EC2 instances

65
00:02:20,800 --> 00:02:22,850
for me to launch tasks on.

66
00:02:22,850 --> 00:02:23,683
So as you can see,

67
00:02:23,683 --> 00:02:25,210
it's in three availability zones.

68
00:02:25,210 --> 00:02:26,490
So we know that the ECS tasks

69
00:02:26,490 --> 00:02:29,210
are going to be launched across three AZ.

70
00:02:29,210 --> 00:02:31,120
And what I'm going to do now is just wait

71
00:02:31,120 --> 00:02:32,900
for this cluster to be created,

72
00:02:32,900 --> 00:02:34,510
which is the case now.

73
00:02:34,510 --> 00:02:37,360
So what I can do now is explore this DemoCluster.

74
00:02:37,360 --> 00:02:39,020
So if I click on it,

75
00:02:39,020 --> 00:02:40,700
I'm in the DemoCluster,

76
00:02:40,700 --> 00:02:42,330
and I can go to services,

77
00:02:42,330 --> 00:02:43,163
there are zero tasks,

78
00:02:43,163 --> 00:02:45,630
there are zero because we haven't launched anything yet.

79
00:02:45,630 --> 00:02:48,490
And then we go to the more interesting infrastructure.

80
00:02:48,490 --> 00:02:50,480
So if you go here to the infrastructure,

81
00:02:50,480 --> 00:02:54,400
we have three capacity providers in this ECS cluster.

82
00:02:54,400 --> 00:02:55,380
The first one is Fargate,

83
00:02:55,380 --> 00:02:57,220
that means that we can launch Fargate task

84
00:02:57,220 --> 00:02:59,020
onto our ECS cluster.

85
00:02:59,020 --> 00:03:00,680
The second one is Fargate Spot,

86
00:03:00,680 --> 00:03:03,710
that means that we can launch Fargate task in spot mode,

87
00:03:03,710 --> 00:03:06,160
so like spot instances for EC2.

88
00:03:06,160 --> 00:03:09,980
And the last one is a ASG Provider,

89
00:03:09,980 --> 00:03:12,910
and this one means that we can launch EC2 instances

90
00:03:12,910 --> 00:03:15,740
in this cluster directly through this ASG.

91
00:03:15,740 --> 00:03:18,170
So it's managed scaling right now,

92
00:03:18,170 --> 00:03:20,380
and the current size is zero,

93
00:03:20,380 --> 00:03:22,630
but I can change it if I wanted to.

94
00:03:22,630 --> 00:03:24,060
So let me show you what it would look like.

95
00:03:24,060 --> 00:03:25,130
I go here,

96
00:03:25,130 --> 00:03:26,830
I go to details,

97
00:03:26,830 --> 00:03:29,630
and I would edit the desired capacity to be one,

98
00:03:29,630 --> 00:03:31,370
just to show you what it's like.

99
00:03:31,370 --> 00:03:32,810
So what's going to happen out of this is

100
00:03:32,810 --> 00:03:37,150
that an EC2 instance is going to be created, okay?

101
00:03:37,150 --> 00:03:37,983
And when it's created,

102
00:03:37,983 --> 00:03:41,363
it's going to register itself into the DemoCluster.

103
00:03:42,520 --> 00:03:45,410
And then I will see it under container instances.

104
00:03:45,410 --> 00:03:47,870
That means that when we create an ECS task,

105
00:03:47,870 --> 00:03:50,260
it can either be launched on a Fargate,

106
00:03:50,260 --> 00:03:52,590
or Fargate Spot capacity provider,

107
00:03:52,590 --> 00:03:55,290
or it can be launched on the container instances

108
00:03:55,290 --> 00:03:58,900
that I will have launched as part of this ASG.

109
00:03:58,900 --> 00:03:59,770
So what I'm going to do now

110
00:03:59,770 --> 00:04:01,110
is just wait for this instance

111
00:04:01,110 --> 00:04:02,230
to be in the running state,

112
00:04:02,230 --> 00:04:04,603
and registered into my ECS cluster.

113
00:04:05,620 --> 00:04:07,000
So let me refresh now.

114
00:04:07,000 --> 00:04:09,580
My instance is in service,

115
00:04:09,580 --> 00:04:10,600
and its t2micro,

116
00:04:10,600 --> 00:04:13,430
and if I go back into my Amazon ECS cluster,

117
00:04:13,430 --> 00:04:16,060
it is registered as a Container instance

118
00:04:16,060 --> 00:04:17,019
that is currently of course,

119
00:04:17,019 --> 00:04:18,140
running zero tasks,

120
00:04:18,140 --> 00:04:21,660
and has 1024 CPU available,

121
00:04:21,660 --> 00:04:25,560
and 982 memory available.

122
00:04:25,560 --> 00:04:28,210
So this is giving me the capacity of this instance,

123
00:04:28,210 --> 00:04:29,630
and I can launch use,

124
00:04:29,630 --> 00:04:30,610
as you'll see task on it

125
00:04:30,610 --> 00:04:32,820
until the capacity runs out.

126
00:04:32,820 --> 00:04:34,050
So we're good to go.

127
00:04:34,050 --> 00:04:35,190
So we have an ECS cluster.

128
00:04:35,190 --> 00:04:36,880
We've seen two capacity providers,

129
00:04:36,880 --> 00:04:38,010
I mean three.

130
00:04:38,010 --> 00:04:39,370
We've seen Container instances.

131
00:04:39,370 --> 00:04:42,920
So now let's go ahead and do run our first service,

132
00:04:42,920 --> 00:04:45,573
and I will see you in the next lecture to do that.
