00:00:04,460 --> 00:00:11,490
We have just discussed such Docker components as a client dog our server that is actually a set of different

2
00:00:11,490 --> 00:00:18,180
processes that are running at Docker host and took our host is actually used for creation of those processes

3
00:00:18,240 --> 00:00:25,080
and creation of different containers on the Mac and Windows dog our host is a beautiful Linux machine

4
00:00:25,290 --> 00:00:33,170
that is running on macros or Windows computer on Linux computers Linux computer is directly Docker host.

5
00:00:33,330 --> 00:00:34,100
Let's not proceed.

6
00:00:34,110 --> 00:00:38,660
And next let's discuss what is Docker image and what is docker container.

7
00:00:38,700 --> 00:00:40,320
And first let me describe you.

8
00:00:40,410 --> 00:00:42,960
What is Docker image.

9
00:00:42,960 --> 00:00:50,760
In simple words I can say that Docker image is simply set of read only files.

10
00:00:50,970 --> 00:00:52,800
That's all.

11
00:00:52,800 --> 00:01:01,050
And based on the image you are able to create container or different containers let's first have a look

12
00:01:01,140 --> 00:01:05,570
at least of images that are already present on my computer.

13
00:01:05,760 --> 00:01:12,930
If I enter Docker image just comment I will see List of images that are present in local cash on this

14
00:01:12,930 --> 00:01:17,070
computer and those images were downloaded from Docker Hub.

15
00:01:17,070 --> 00:01:23,340
Actually I have downloaded all those images during the previous chapter where we have used different

16
00:01:23,550 --> 00:01:29,760
images and when we have created different containers based on those images but again every image is

17
00:01:29,760 --> 00:01:31,310
just set off files.

18
00:01:31,380 --> 00:01:39,030
But talking more correctly it is set of a file system layers we will get back to it pretty soon.

19
00:01:39,030 --> 00:01:45,810
For now just understand that every image is read only set of files that is used for creation of containers.

20
00:01:45,810 --> 00:01:53,100
That's all in this list you see actually images that were created already by someone else but you are

21
00:01:53,100 --> 00:01:58,610
also able to create your costume images and reuse them for creation of containers.

22
00:01:58,920 --> 00:02:00,170
But what is container.

23
00:02:00,180 --> 00:02:01,910
Let me explain your death in the next layer.

24
00:02:01,910 --> 00:02:03,490
Sure I'll see you just in a bit.

25
00:02:03,510 --> 00:02:03,860
Bye bye.
