1
00:00:01,230 --> 00:00:04,840
In this video Oregon do some initial setup of the Nats streaming server.

2
00:00:04,890 --> 00:00:09,570
I first want to give you just a couple of very high level notes on it and we're going to start to deploy

3
00:00:09,570 --> 00:00:13,890
it into our Cuban businesses cluster by writing as you'd guess a config file.

4
00:00:13,930 --> 00:00:14,210
Okay.

5
00:00:14,250 --> 00:00:15,340
So a couple notes here.

6
00:00:15,480 --> 00:00:20,850
So we're making use of something called Nats streaming server to share events across all the different

7
00:00:20,850 --> 00:00:23,130
services inside of application.

8
00:00:23,130 --> 00:00:29,870
You can find documentation for Nat streaming server at docks that Nat Scott Io it's all going to go

9
00:00:29,870 --> 00:00:31,280
there right now.

10
00:00:31,280 --> 00:00:33,310
Here's the documentation page.

11
00:00:33,500 --> 00:00:37,610
Now it's something that is extremely important for you to understand right from the get go.

12
00:00:37,610 --> 00:00:39,360
This is extremely important.

13
00:00:39,410 --> 00:00:44,630
Are going to see it terminology of simply Nats and Nats streaming server.

14
00:00:44,630 --> 00:00:50,660
These are two separate programs two different things and they behave pretty darn differently.

15
00:00:50,660 --> 00:00:57,440
We are not making use of nets NASA is a very simple basic implementation of event sharing Nats streaming

16
00:00:57,440 --> 00:00:59,910
server is built on top of Nats.

17
00:00:59,960 --> 00:01:05,530
It is a more advanced and more full of feature implementation that we are going to be making use of.

18
00:01:05,600 --> 00:01:11,210
So in all the documentation that we look at in all the deployment instructions everything we always

19
00:01:11,210 --> 00:01:16,170
want to be making sure that we're taking a look at something that says Nats streaming server.

20
00:01:16,340 --> 00:01:18,510
Hundred percent of the time.

21
00:01:18,560 --> 00:01:23,120
Having said that throughout the remainder of this course and particularly in this section whenever I

22
00:01:23,120 --> 00:01:28,010
want to refer to that streaming server I'm going to very frequently say simply Nats just because saying

23
00:01:28,010 --> 00:01:32,160
that streaming server over and over and over again is going to be really annoying.

24
00:01:32,240 --> 00:01:36,380
So for you just keep in mind that we're always going to want to look at documentation around Nat streaming

25
00:01:36,380 --> 00:01:41,630
server and this applies even to the official documentation once we come over here on the left hand side

26
00:01:41,630 --> 00:01:46,520
we're going to see stuff that says Nats concepts developing with Nats and so on that is all references

27
00:01:46,520 --> 00:01:52,790
to just plain NATS which we're not using we are using Nats streaming server so the documentation we

28
00:01:52,790 --> 00:01:53,420
want to look at.

29
00:01:53,450 --> 00:02:00,090
We're going to scroll down on the left hand side and eventually find Nats streaming concepts.

30
00:02:00,090 --> 00:02:05,000
These are the documentation sections we care about is developing with that streaming.

31
00:02:05,080 --> 00:02:07,250
Yep we care about that and here's Nats streaming server.

32
00:02:07,260 --> 00:02:07,450
Yep.

33
00:02:07,470 --> 00:02:08,190
We care about that.

34
00:02:08,730 --> 00:02:10,980
So again make sure you are not reading about Nats.

35
00:02:10,980 --> 00:02:15,010
Make sure you are reading about Nats streaming server.

36
00:02:15,260 --> 00:02:21,720
So that mind some many different features of Nat streaming are going to be absolutely tremendous in

37
00:02:21,730 --> 00:02:25,870
how we eventually start to implement some of our different services and particularly how we share data

38
00:02:25,900 --> 00:02:26,700
between them.

39
00:02:26,760 --> 00:02:30,610
So in the coming videos we're going to get Nat streaming server up and running inside of our carbonated

40
00:02:30,640 --> 00:02:31,300
cluster.

41
00:02:31,330 --> 00:02:35,830
We're going to create a very small little project where we are just writing out some no J.S. code to

42
00:02:35,830 --> 00:02:40,570
work with Nat streaming server directly so we can get a better idea of how it behaves how it shares

43
00:02:40,570 --> 00:02:46,180
information around how he vents get persisted how we can somehow synchronize new services that we add

44
00:02:46,180 --> 00:02:48,760
into our application insulin.

45
00:02:48,870 --> 00:02:53,740
We are going to run Nat streaming server inside of our Cuban cities cluster by using the official Docker

46
00:02:53,740 --> 00:02:56,140
image called Nats streaming.

47
00:02:56,230 --> 00:02:59,800
Let's go take a look at the image documentation on Docker Hub right now.

48
00:02:59,860 --> 00:03:04,750
Just we have a better idea of how we can get the thing up and running so inside of a second browser

49
00:03:04,750 --> 00:03:11,200
tab I'm going to navigate to hub Docker at dot com and then once here I will search for NATS at the

50
00:03:11,200 --> 00:03:18,540
top and again we're going to see it one image called Nats and another called Nats streaming.

51
00:03:18,540 --> 00:03:21,210
So again we want to make sure we are always going for NATS.

52
00:03:21,240 --> 00:03:28,380
Streaming then on this page we can take a look at some documentation the documentation I really want

53
00:03:28,380 --> 00:03:37,470
to point out to you is at the very very bottom of this page though specifically the command line options.

54
00:03:37,570 --> 00:03:42,190
These are a ton of different options that we can provide when we create our deployment.

55
00:03:42,220 --> 00:03:47,210
I'll show you how we stick these in and these are going to customize Howard Nordstrom's over behaves.

56
00:03:47,210 --> 00:03:51,740
Some of these options are really important for us to set and in some cases we definitely do not want

57
00:03:51,740 --> 00:03:54,480
to be using the default settings.

58
00:03:54,580 --> 00:03:54,890
All right.

59
00:03:54,920 --> 00:03:57,350
So in this video we've really established three things.

60
00:03:57,350 --> 00:04:01,180
Number one we're using that streaming server not Nats.

61
00:04:01,210 --> 00:04:05,500
Number two we're going to take a look at the Nats documentation and when we do we're going to make sure

62
00:04:05,500 --> 00:04:08,590
we take a look at these streaming documentation.

63
00:04:08,590 --> 00:04:13,510
And number three we're going to run that streaming server inside of our carbonated cluster by deploying

64
00:04:13,510 --> 00:04:19,210
it like any other service in our app and I guess number three point five or so.

65
00:04:19,260 --> 00:04:20,860
We definitely want to keep this page open.

66
00:04:20,880 --> 00:04:25,470
The Docker Hub documentation on the nat streaming image so we can take a look at the different command

67
00:04:25,470 --> 00:04:27,820
line options that are available to us.

68
00:04:27,960 --> 00:04:28,280
All right.

69
00:04:28,300 --> 00:04:29,310
It's a quick pause right here.

70
00:04:29,310 --> 00:04:33,780
We're going to start to deploy this into our cluster in the next video by writing a deployment.
