00:00:00,570 --> 00:00:03,630
In last section we tried to answer the question what is Docker.

2
00:00:03,630 --> 00:00:05,790
But we didn't really get a great explanation.

3
00:00:05,790 --> 00:00:08,200
We said Okay it's a reference to a bunch of products.

4
00:00:08,220 --> 00:00:12,030
We then started to talk about something called an image and something called a container.

5
00:00:12,150 --> 00:00:16,800
At this point we need to install some more software onto our machine so that you and I can work directly

6
00:00:16,800 --> 00:00:21,070
with images and containers so that we can get a better idea of how they work.

7
00:00:21,090 --> 00:00:22,910
So here's what you and I are going to do.

8
00:00:23,040 --> 00:00:28,500
We're going to be installing a piece of software called Docker for Windows or Docker from Mac depending

9
00:00:28,500 --> 00:00:34,080
upon your operating system inside of this program are two very important tools that we're going to be

10
00:00:34,080 --> 00:00:36,580
making use of throughout this course.

11
00:00:36,600 --> 00:00:40,580
The first tool that's inside this package is something called the docker client.

12
00:00:40,740 --> 00:00:45,270
The Docker client also known as the docker Seelye is a program that you and I are going to interact

13
00:00:45,270 --> 00:00:47,370
with quite a bit from our terminal.

14
00:00:47,400 --> 00:00:51,230
We're going to enter in commands to our terminal issue them to Docker client.

15
00:00:51,270 --> 00:00:54,380
It's gonna take our commands and figure out what to do with them.

16
00:00:54,570 --> 00:01:00,380
Now Docker the docker client itself doesn't actually do anything with containers or images.

17
00:01:00,390 --> 00:01:06,840
Instead the docker client is really just a tool or a portal of sorts to help us interact with another

18
00:01:06,840 --> 00:01:12,610
piece of software that is included in this Docker for Windows or Mac package called the docker server.

19
00:01:12,660 --> 00:01:15,500
This is also frequently called the docker Damon.

20
00:01:15,600 --> 00:01:20,850
This program right here is the actual tool or the actual piece of software that is responsible for creating

21
00:01:20,850 --> 00:01:27,360
containers images maintaining containers uploading images and doing just about everything you can possibly

22
00:01:27,360 --> 00:01:29,710
imagine around the world of Docker.

23
00:01:29,760 --> 00:01:32,430
So it's the docker client that you and I issue commands to.

24
00:01:32,430 --> 00:01:34,010
It's a thing that we interact with.

25
00:01:34,140 --> 00:01:38,610
And behind the scenes this client is interacting with the docker server.

26
00:01:38,610 --> 00:01:42,000
You and I are never going to really reach directly out to this Docker server.

27
00:01:42,000 --> 00:01:45,240
It's something that's just kind of running it behind the scenes.

28
00:01:45,270 --> 00:01:47,490
So again we're gonna take a quick break right now.

29
00:01:47,490 --> 00:01:51,330
We're going to come back the next section and we're going to start installing this package so that we

30
00:01:51,330 --> 00:01:55,140
can get a better sense of how to work with images and containers.

31
00:01:55,140 --> 00:01:57,060
So quick break and I'll see you in just a minute.
