00:00:00,740 --> 00:00:02,560
- [Alana] Welcome to Exercise 1.

2
00:00:02,560 --> 00:00:05,330
In this exercise, you'll be
using your own AWS accounts

3
00:00:05,330 --> 00:00:06,960
to create an EC2 instance

4
00:00:06,960 --> 00:00:09,360
that you later deploy to with CodeDeploy.

5
00:00:09,360 --> 00:00:10,890
If you don't have an AWS account,

6
00:00:10,890 --> 00:00:12,520
refer to the reading before this video

7
00:00:12,520 --> 00:00:15,610
called Create Your Own AWS Account.

8
00:00:15,610 --> 00:00:17,240
Here's how this will work.

9
00:00:17,240 --> 00:00:19,330
Your EC2 instance is what we'll refer

10
00:00:19,330 --> 00:00:21,380
to as your test environment.

11
00:00:21,380 --> 00:00:22,970
You'll be creating this.

12
00:00:22,970 --> 00:00:25,180
In Exercise 2, you will use CodeDeploy

13
00:00:25,180 --> 00:00:28,220
to eventually deploy code
to this test environment.

14
00:00:28,220 --> 00:00:29,810
And that code will be stored

15
00:00:29,810 --> 00:00:33,300
in Amazon Simple Storage
Service, or Amazon S3,

16
00:00:33,300 --> 00:00:35,570
which is an object storage service.

17
00:00:35,570 --> 00:00:37,840
Sounds simple enough, right?

18
00:00:37,840 --> 00:00:39,540
But there's a lot that needs to happen

19
00:00:39,540 --> 00:00:41,750
behind the scenes to make this work.

20
00:00:41,750 --> 00:00:42,650
For example,

21
00:00:42,650 --> 00:00:45,410
all of these services need to
communicate with each other,

22
00:00:45,410 --> 00:00:46,790
and none of that communication

23
00:00:46,790 --> 00:00:49,620
is allowed or enabled by default.

24
00:00:49,620 --> 00:00:52,410
That means CodeDeploy needs
to communicate with EC2,

25
00:00:52,410 --> 00:00:55,040
and EC2 needs to communicate with S3.

26
00:00:55,040 --> 00:00:57,173
And we have to set all of this up.

27
00:00:58,450 --> 00:01:00,650
To do this, We'll do a few things.

28
00:01:00,650 --> 00:01:01,741
The first is, we'll create

29
00:01:01,741 --> 00:01:03,750
AWS Identity and Access Management,

30
00:01:03,750 --> 00:01:08,010
or IAM roles for the services
to enable communication.

31
00:01:08,010 --> 00:01:10,360
So, for EC2, we'll create an IAM role

32
00:01:10,360 --> 00:01:12,000
that has permissions to S3,

33
00:01:12,000 --> 00:01:14,880
and assign it to our
instance when we create it.

34
00:01:14,880 --> 00:01:18,790
That will enable the EC2 instance
to grab the code from S3.

35
00:01:18,790 --> 00:01:21,205
We'll also assign a policy
that has permissions to

36
00:01:21,205 --> 00:01:23,380
AWS Systems Manager Session Manager,

37
00:01:23,380 --> 00:01:26,310
which will enable us to
remotely connect to our instance

38
00:01:26,310 --> 00:01:29,090
without having to manage SSH keys.

39
00:01:29,090 --> 00:01:31,330
Then, we'll create a
service role for CodeDeploy,

40
00:01:31,330 --> 00:01:34,098
which will allow CodeDeploy
to call other AWS services,

41
00:01:34,098 --> 00:01:36,500
including Amazon EC2.

42
00:01:36,500 --> 00:01:38,050
So, that's great.

43
00:01:38,050 --> 00:01:39,810
Two roles that will enable communication

44
00:01:39,810 --> 00:01:41,700
to flow between the services.

45
00:01:41,700 --> 00:01:43,410
We're done, right?

46
00:01:43,410 --> 00:01:45,410
Well, not so fast.

47
00:01:45,410 --> 00:01:47,630
For CodeDeploy to communicate with EC2,

48
00:01:47,630 --> 00:01:49,830
we not only need a role,

49
00:01:49,830 --> 00:01:53,850
we also need to install the
CodeDeploy agent on EC2 as well.

50
00:01:53,850 --> 00:01:54,920
So, in the lab,

51
00:01:54,920 --> 00:01:56,890
after you create your EC2 instance,

52
00:01:56,890 --> 00:01:58,760
or your test environment,

53
00:01:58,760 --> 00:02:01,670
you'll connect to your
instance and install the agent.

54
00:02:01,670 --> 00:02:04,180
And that enables CodeDeploy
to use this instance

55
00:02:04,180 --> 00:02:06,270
for future deployments.

56
00:02:06,270 --> 00:02:09,240
You'll also need to install
the AWS Systems Manager agent

57
00:02:09,240 --> 00:02:10,600
on your instance as well,

58
00:02:10,600 --> 00:02:13,450
to ensure that you can remotely
connect to your instance.

59
00:02:14,430 --> 00:02:16,068
So, what you'll be creating: roles,

60
00:02:16,068 --> 00:02:19,450
creating an instance, and
connecting to that instance

61
00:02:19,450 --> 00:02:22,740
to deploy an agent, and all
of this will be built upon

62
00:02:22,740 --> 00:02:24,160
in the second lab.

63
00:02:24,160 --> 00:02:25,940
If you have any questions,

64
00:02:25,940 --> 00:02:27,380
feel free to post in the forums

65
00:02:27,380 --> 00:02:29,140
and get help from one another.

66
00:02:29,140 --> 00:02:30,410
If you see a question in the forums

67
00:02:30,410 --> 00:02:31,580
that you know the answer to,

68
00:02:31,580 --> 00:02:33,850
I encourage you to respond to others.

69
00:02:33,850 --> 00:02:37,330
The instructors will also be
monitoring the forums as well.

70
00:02:37,330 --> 00:02:39,753
All right, go ahead and get started.
