00:00:00,439 --> 00:00:06,180
Now that we've created our VPC
architecture we can now look at
1

2
00:00:06,180 --> 00:00:12,360
deploying our ec2 instances into that 
VPC, so the first thing we need to do
2

3
00:00:12,360 --> 00:00:18,660
before we create an ec2 instance is that
we need to create a security group for
3

4
00:00:18,660 --> 00:00:23,220
that instance so what we do is again we
go to the ec2 section we scroll down to
4

5
00:00:23,220 --> 00:00:27,420
the security group and we drop that on
to the VPC we don't drop that onto the
5

6
00:00:27,420 --> 00:00:34,170
public subnet drop it onto the VPC okay
we'll rename that again so we click on
6

7
00:00:34,170 --> 00:00:43,290
components and I'm just going to rename
there any in backspace ec2 SG will be
7

8
00:00:43,290 --> 00:00:52,800
fine for us and we'll update our
designer so now our security group has a
8

9
00:00:52,800 --> 00:00:59,129
number of the dots that the the all of
these icons have has depends on but the
9

10
00:00:59,129 --> 00:01:02,550
one that we're interested in now is in
the bottom right hand side here we've
10

11
00:01:02,550 --> 00:01:09,180
got VPC ID so if we click on that we
can see the VPC is seen highlighted and
11

12
00:01:09,180 --> 00:01:13,890
we just go through and drop that onto
the VPC and that will make sure that
12

13
00:01:13,890 --> 00:01:20,909
our VPC ID is referenced in that
security group so we also need to add
13

14
00:01:20,909 --> 00:01:25,650
some more properties in there so I've
just copied those over from the lab
14

15
00:01:25,650 --> 00:01:32,490
notes and paste those in there
okay so what we need to make sure is
15

16
00:01:32,490 --> 00:01:39,720
that when we paste it in that the
indenting lines up with this here so it
16

17
00:01:39,720 --> 00:01:45,180
indents from properties and it will be
in line with VPC id, it'll be like that
17

18
00:01:45,180 --> 00:01:50,159
and then when we go into our security
ingress rule that will be indented again
18

19
00:01:50,159 --> 00:01:56,280
with IP protocol and then the from to
port and side a block will then be
19

20
00:01:56,280 --> 00:02:02,000
indented again and then we go back and
so that is a TCP port 80 connection for
20

21
00:02:02,000 --> 00:02:08,910
for everything and then we have our port
20 to ssh traffic
21

22
00:02:08,910 --> 00:02:15,780
therefore IP protocol TCP so that is our
security group ingress rules that have
22

23
00:02:15,780 --> 00:02:21,510
been defined them so again we click on
it refresh and that will update that for us
23

24
00:02:21,510 --> 00:02:28,620
okay so now that we've done that we
can now look at saving it again as a
24

25
00:02:28,620 --> 00:02:36,450
different version so we'll save that
local file and we'll call this one too
25

26
00:02:36,450 --> 00:02:48,540
so again we go into our cloud formation
console we leave it we've already saved
26

27
00:02:48,540 --> 00:02:54,720
that that's fine and again we go through
and we'll select our stack and we'll
27

28
00:02:54,720 --> 00:02:59,959
update our stack choose our file again
28

29
00:03:00,170 --> 00:03:19,949
and next and next next and update ok so
that update has completed fine it's it's
29

30
00:03:19,949 --> 00:03:26,190
created the security group not a problem
there ok so let's go back into designer
30

31
00:03:26,190 --> 00:03:33,290
so click on design template will load
that back in again
31

32
00:03:38,209 --> 00:03:51,209
okay just zoom in a bit okay so I'll
just minimize the editor now now that
32

33
00:03:51,209 --> 00:03:56,219
we've got our security grid created we
now can go ahead and put our ec2
33

34
00:03:56,219 --> 00:04:01,139
instance in there so again we see two
and drag an instance across into here
34

35
00:04:01,139 --> 00:04:08,549
again we'll rename that instance so we
click on components and we'll rename
35

36
00:04:08,549 --> 00:04:20,669
that so we're just call a back space ec2
I that will be fine
36

37
00:04:20,669 --> 00:04:28,830
refresh our designer, Okay I'll just
minimize the editor so that we can see
37

38
00:04:28,830 --> 00:04:33,570
it a little bit better so again we've
got a lot of different stuff here but
38

39
00:04:33,570 --> 00:04:38,870
what we're interested in is that depends
on so it depends we can't create this
39

40
00:04:38,870 --> 00:04:45,000
ec2 instance until our route to the
Internet is there available otherwise
40

41
00:04:45,000 --> 00:04:48,509
it's just not going to be able to
connect so has no point launching an ec2
41

42
00:04:48,509 --> 00:04:53,099
instance until that is ready to go so we
put our depends on so the pink dot there
42

43
00:04:53,099 --> 00:05:03,090
and we drag that over to our public
route okay so now that we've got that
43

44
00:05:03,090 --> 00:05:09,780
instance icon on there we need to
actually define you know what what ami
44

45
00:05:09,780 --> 00:05:15,599
is instance using we need to define also
what size that instance is so we can
45

46
00:05:15,599 --> 00:05:19,320
start off by putting that into the
property so we click on that we'll just
46

47
00:05:19,320 --> 00:05:25,130
max or split screen to get the editor up
click on components to bring that up and
47

48
00:05:25,130 --> 00:05:30,270
we can see that we've got our subnet ID
reference that's fine so what we need to
48

49
00:05:30,270 --> 00:05:35,969
do is to go into properties and just
before network interfaces and press
49

50
00:05:35,969 --> 00:05:43,620
enter and we're going to copy over the
the details of that instance so just
50

51
00:05:43,620 --> 00:05:48,770
copy that over from the lab notes
51

52
00:05:51,180 --> 00:05:58,060
okay so make sure that it looks like
that so you have properties and then you
52

53
00:05:58,060 --> 00:06:03,310
have an indent of two spaces then your
image ID and then the instance type and
53

54
00:06:03,310 --> 00:06:09,150
then lining up again will be the network
interfaces after that so again we
54

55
00:06:09,150 --> 00:06:17,440
refresh our designer so now that we've
got our our image ID which is a
55

56
00:06:17,440 --> 00:06:21,699
wordpress image in our instance type we
need to give information about the a
56

57
00:06:21,699 --> 00:06:26,020
network interface side of things so
again we'll copy that over from the lab
57

58
00:06:26,020 --> 00:06:39,370
notes and we'll paste that in to where
the current network interfaces section
58

59
00:06:39,370 --> 00:06:48,910
is delete that one and we'll paste the
new one in okay so I'm just going to
59

60
00:06:48,910 --> 00:06:54,099
maximize this and we can see it a little
bit better so there we go so we've got
60

61
00:06:54,099 --> 00:06:59,050
our image ID which is a wordpress AMI
we've got our t2 micro and then in the
61

62
00:06:59,050 --> 00:07:04,360
networking section we've got our group
set set which is our back space ec2
62

63
00:07:04,360 --> 00:07:09,669
security group which is associated with
this instance we wanted to associate a
63

64
00:07:09,669 --> 00:07:13,630
public IP address when it launches it's
going to be a webserver it needs a
64

65
00:07:13,630 --> 00:07:19,060
public IP address we have a device index
air and delete on termination being true
65

66
00:07:19,060 --> 00:07:25,360
so when we terminate it we want it to go
and we have a subnet ID there which is
66

67
00:07:25,360 --> 00:07:31,630
defined it's going into our public
subnet so we'll just go back to split
67

68
00:07:31,630 --> 00:07:35,550
screen and we'll refresh our designer
68

69
00:07:37,289 --> 00:07:45,220
okay so now that we've done that we can
look at now deploying our doing our
69

70
00:07:45,220 --> 00:07:49,419
final update which will deploy our
WordPress server to this VPC
70

71
00:07:49,419 --> 00:07:55,870
architecture so again we save our
current template to a local file we'll
71

72
00:07:55,870 --> 00:08:01,690
save that and we're going to give it the
name backspace three
72

73
00:08:01,690 --> 00:08:06,590
and we'll save that one there when
that's finished saving we go again into
73

74
00:08:06,590 --> 00:08:16,180
the cloud formation console we click on
that stack and we update that stack
74

75
00:08:16,180 --> 00:08:30,199
we'll choose our new file upload that
click on next and next and next and
75

76
00:08:30,199 --> 00:08:36,740
we'll update that stack so the update is
near in progress after short them at a
76

77
00:08:36,740 --> 00:08:40,880
time it will be ready to go and we can
start to have a look at our web server
77

78
00:08:40,880 --> 00:08:48,820
in action okay so our update has been
completed so our architecture has been
78

79
00:08:48,820 --> 00:08:56,510
created and our ec2 instance has been
created and a route through to the
79

80
00:08:56,510 --> 00:09:00,380
Internet has been created so we should
be able to now point our web server
80

81
00:09:00,380 --> 00:09:05,810
you're sorry should be able to point our
browser to this WordPress web server and
81

82
00:09:05,810 --> 00:09:17,240
we should get a web page so let's go to
the ec2 console and then we can see we
82

83
00:09:17,240 --> 00:09:28,459
got one running instance seeing okay so
there's our instance and it's still
83

84
00:09:28,459 --> 00:09:34,970
going through doing it status checks so
we just wait for it to finish that okay
84

85
00:09:34,970 --> 00:09:41,240
so our status checks have completed so
we should now be able to or very shortly
85

86
00:09:41,240 --> 00:09:46,250
be able to access our web server so we
just go and get the public IP address
86

87
00:09:46,250 --> 00:09:52,339
and we'll go to that so just go to that
and there you can see we have our
87

88
00:09:52,339 --> 00:09:58,250
WordPress server up and running so
that's a pretty cool thing so this has
88

89
00:09:58,250 --> 00:10:04,010
been a very very long lab but I'm sure
you can appreciate that this is a great
89

90
00:10:04,010 --> 00:10:09,410
way to really learn about VPC you're
going to understand what is required for
90

91
00:10:09,410 --> 00:10:13,310
internet access you're going to
understand exactly if any of this stuff
91

92
00:10:13,310 --> 00:10:17,040
is missing it's not going to
I'm sure you've learned a lot about
92

93
00:10:17,040 --> 00:10:23,640
cloud formation as well and how how to
launch a stack and how to fix a stack if
93

94
00:10:23,640 --> 00:10:28,290
there are problems with it so that
brings us to the end all we need to do
94

95
00:10:28,290 --> 00:10:33,600
now is to clean this up so what we do is
we just close out of here we don't go
95

96
00:10:33,600 --> 00:10:39,210
anywhere near the ec2 management console
leave that alone if you delete it from
96

97
00:10:39,210 --> 00:10:42,600
here it's going to create problems when
you go to delete the slacks and don't
97

98
00:10:42,600 --> 00:10:48,180
touch anything here go back into cloud
formation and delete the stack from
98

99
00:10:48,180 --> 00:10:55,620
there first so just select it actions
and delete stack so when you delete a
99

100
00:10:55,620 --> 00:11:00,660
stack it will delete every resource that
was created so it's going to delete that
100

101
00:11:00,660 --> 00:11:05,130
entire VPC that we've created
it's going to delete the security groups
101

102
00:11:05,130 --> 00:11:09,180
around tables it's going to delete
finally delete that instance as well so
102

103
00:11:09,180 --> 00:11:18,060
we cook on yes delete that delete will
be happening okay so after a certain
103

104
00:11:18,060 --> 00:11:22,230
amount of time you're going to see that
stack deleted and all of the resources
104

105
00:11:22,230 --> 00:11:26,820
that were created by that stack will
also be deleted now this is a very big
105

106
00:11:26,820 --> 00:11:33,420
lab quite a complex lab I've created
almost 30 pages of lab notes and make
106

107
00:11:33,420 --> 00:11:38,040
sure you download those it's taken about
a week of full time to get this lab up
107

108
00:11:38,040 --> 00:11:42,810
and running and I hope you appreciate it
because it's going to really be a really
108

109
00:11:42,810 --> 00:11:48,150
good lab for you to learn and fully
understand VPC so make sure you download
109

110
00:11:48,150 --> 00:11:53,730
those lab dates go through them very
carefully take your time and you'll get
110

111
00:11:53,730 --> 00:11:59,990
there in the end and I'll look forward
to seeing you in the next lecture
