00:00:01,830 --> 00:00:06,160
Our application is up and running successfully inside of our cluster which is fantastic.

2
00:00:06,210 --> 00:00:10,470
But as I've mentioned several times in the last couple of videos making changes to our code base right

3
00:00:10,470 --> 00:00:12,280
now is a real pain.

4
00:00:12,420 --> 00:00:14,220
So you might recall look at this diagram.

5
00:00:14,280 --> 00:00:19,320
These are the steps we go through any time they want to change the image that is used by a deployment.

6
00:00:19,320 --> 00:00:22,740
So we've been saying that to really change the code running inside of our pods.

7
00:00:22,800 --> 00:00:24,680
We had to make an update to our code.

8
00:00:24,750 --> 00:00:29,130
We had to rebuild the image push it to Docker Hub and then run a command.

9
00:00:29,130 --> 00:00:35,710
This is a total nightmare to have to do that would result in a very very unpleasant development process.

10
00:00:35,730 --> 00:00:39,630
Now it is still important for you to understand this process right here because this is how we're going

11
00:00:39,630 --> 00:00:44,010
to eventually deploy code in a production style environment still important for you to understand this

12
00:00:44,280 --> 00:00:48,760
but in a development environment clearly this is not a very great approach.

13
00:00:48,810 --> 00:00:52,220
So we are developing code actively inside of a carbonates cluster.

14
00:00:52,240 --> 00:00:58,500
We're going to instead use a tool called scaffold scaffold is a command line tool that we're going to

15
00:00:58,500 --> 00:01:05,280
use to automatically do a lot of different tasks in our communities dev environment specifically.

16
00:01:05,280 --> 00:01:09,450
You can't use scaffold in a production environment but for you and I really just going to focus on using

17
00:01:09,450 --> 00:01:11,080
it in development.

18
00:01:11,280 --> 00:01:16,380
The number one thing that we are interested in with scaffold is that it makes it super easy to update

19
00:01:16,380 --> 00:01:18,260
Code in a running pod.

20
00:01:18,270 --> 00:01:22,900
It's essentially just as quickly as if we were not using commodities at all.

21
00:01:22,950 --> 00:01:27,840
The other really great thing about scaffold is that it makes it very easy for us to create and delete

22
00:01:28,110 --> 00:01:30,700
all the different objects that are tied to some project.

23
00:01:30,900 --> 00:01:32,170
Very very quickly.

24
00:01:32,280 --> 00:01:33,230
And that's really important.

25
00:01:33,240 --> 00:01:38,160
If we start working between multiple different Cuban cities projects when you running a cluster on your

26
00:01:38,160 --> 00:01:40,610
local machine there is just one cluster.

27
00:01:40,650 --> 00:01:45,510
So if you start to work between different projects maybe right now you're working on this application

28
00:01:45,510 --> 00:01:49,760
in this course maybe tomorrow you're going to be working on another tutorial or a production app.

29
00:01:49,770 --> 00:01:51,190
Who knows you're going to be.

30
00:01:51,220 --> 00:01:56,790
Want to be able to change between these different sets of objects very quickly and you can do that very

31
00:01:56,790 --> 00:01:59,010
quickly using scaffold.

32
00:01:59,240 --> 00:01:59,530
All right.

33
00:01:59,630 --> 00:02:02,210
So best way to understand scaffold is of course to use it.

34
00:02:02,220 --> 00:02:06,740
So let's just go ahead and install this thing and get get a better idea of what is going on the home

35
00:02:06,740 --> 00:02:12,890
page for scaffold is scaffold dot Dev it's inside of a new browser tab I will go to a scaffold dot Dev

36
00:02:15,190 --> 00:02:20,110
once a year you will see a link on left hand side that says Get scaffold so click on that and then you

37
00:02:20,110 --> 00:02:27,790
will see installation directions on here or Linux Mac OS and Windows the Windows installation directions

38
00:02:27,820 --> 00:02:30,520
are assuming that you have chocolaty already installed.

39
00:02:30,670 --> 00:02:35,440
If you do not have chocolaty or if you don't know what it is I encourage you to do a google search of

40
00:02:35,440 --> 00:02:41,350
chocolatey it make sure you get it installed on your local system if you followed the Mac OS install

41
00:02:41,350 --> 00:02:41,820
directions.

42
00:02:41,830 --> 00:02:44,160
This is assuming that you have homebrew installed as well.

43
00:02:44,230 --> 00:02:49,380
And of course if you don't have homebrew installed again do a quick google search install homebrew to

44
00:02:49,400 --> 00:02:52,900
go ahead and follow the directions for your appropriate operating system.

45
00:02:53,060 --> 00:02:58,430
In just about every case it's gonna be a pretty simple install one command from Mac OS one for Windows

46
00:02:58,640 --> 00:02:59,900
and just a handful of commands.

47
00:02:59,900 --> 00:03:06,000
If you're on Linux to go ahead and get that all setup will come to get back together in the next video

48
00:03:06,030 --> 00:03:08,340
and we'll start to use scaffold inside of our project.
