00:00:04,430 --> 00:00:10,790
In the previous lecture I have shown you what is a client and basically it is separate executable file

2
00:00:10,790 --> 00:00:16,850
located on your computer where you have Dockery installed and with help of a client you are able to

3
00:00:16,910 --> 00:00:20,630
connect to a demon and send some commands to you.

4
00:00:20,660 --> 00:00:26,540
For example you could say please start the container with a will to image or please at least two images

5
00:00:26,570 --> 00:00:27,250
and so on.

6
00:00:27,270 --> 00:00:32,159
Just sending commands to block our server and getting some output from it.

7
00:00:32,180 --> 00:00:38,660
Now let me talk in the dailies about Dr Sara look our Sara is actually set of different processes and

8
00:00:38,700 --> 00:00:41,180
docker demon is one of them.

9
00:00:41,180 --> 00:00:47,240
Let me go back to timing though and the here last command that they have executed was Dr. Morrison and

10
00:00:47,300 --> 00:00:54,290
I have shown you that when Dr Sara is stopped we will see such error cannot connect to book a demon.

11
00:00:54,350 --> 00:01:01,640
No let me execute the same command once again because no Dr Sara is running again and here in this output

12
00:01:01,700 --> 00:01:07,970
you'll see several blocks throws the block is information about engine here you see it's virus and it

13
00:01:07,970 --> 00:01:08,860
actually matches.

14
00:01:08,870 --> 00:01:11,670
In my case somewhere else none of the docker client.

15
00:01:11,750 --> 00:01:14,210
Also next you see API of origin.

16
00:01:14,360 --> 00:01:20,810
And basically this a version is important for communication with Docker client because a client communicates

17
00:01:20,810 --> 00:01:23,990
with Docker etcetera by API.

18
00:01:24,140 --> 00:01:32,280
Next you see goal line version because again Sara and client are written in goal landing and both set

19
00:01:32,290 --> 00:01:35,160
from the client are available in GitHub repository.

20
00:01:35,240 --> 00:01:43,240
And here you see the same last comment that was used for this repository at GitHub next you see built

21
00:01:43,250 --> 00:01:52,400
date and underlined OIS architecture and here in this output you see Linux Linux and d 64 but Docker

22
00:01:52,610 --> 00:01:56,510
in this case on my computer is running on Mac OS.

23
00:01:56,540 --> 00:02:02,570
But here you see OIS architecture Linux and that's what I've told you before.

24
00:02:02,570 --> 00:02:10,070
If you run Docker on Mac or Windows Docker creates small Linux virtual machine and that you see here

25
00:02:10,100 --> 00:02:17,270
in this output next you see information about our processes that are running on our server like a container

26
00:02:17,270 --> 00:02:19,480
of D around C and docker.

27
00:02:19,490 --> 00:02:25,210
You need this process longer you need is a responsible for start of the dock etcetera.

28
00:02:25,250 --> 00:02:32,450
This process is responsible of creation of containers at the high level but at the low level it communicates

29
00:02:32,510 --> 00:02:35,420
with Iran C brought us around container.

30
00:02:35,420 --> 00:02:42,140
This process works closely to linux kernel and it is responsible for allocation of resources to containers

31
00:02:42,350 --> 00:02:50,240
for management of processes and so on and again Dr Sarah is simply set of different processes.

32
00:02:50,240 --> 00:02:55,660
All right let me now quickly switch to a wound to Sarah and ant or same command here.

33
00:02:55,720 --> 00:03:03,430
Dr. Morrison and I'll see similar output here as information about Docker client and here was information

34
00:03:03,440 --> 00:03:04,840
blog about Docker.

35
00:03:04,880 --> 00:03:12,440
Sara and Mike is here at this a boon to computer and here at this Matt Goss computer Docker and innovation

36
00:03:12,560 --> 00:03:20,390
is the same night in all three but eight by difference is that here Docker engine was installed directly

37
00:03:20,390 --> 00:03:28,040
on this one to computer and on Mac was Deloris Docker desktop that has created additional intermediate

38
00:03:28,370 --> 00:03:30,950
small Linux your total machine.

39
00:03:30,970 --> 00:03:33,070
All right guys that's all for this lecture.

40
00:03:33,140 --> 00:03:33,660
And next.

41
00:03:33,680 --> 00:03:38,870
Let's discuss what is our host and I'll demonstrate you what does look our host on Michael's computer

42
00:03:39,080 --> 00:03:40,490
and a window computer.

43
00:03:40,520 --> 00:03:41,890
I'll see you in the next lecture.

44
00:03:41,920 --> 00:03:42,230
Bye bye.
