00:00:04,530 --> 00:00:10,630
That's all, guys, for this section where I have made a brief introduction into Docker images and containers.

2
00:00:10,650 --> 00:00:16,860
We have tried to pull images from Docker Hub and to create new containers based on those images.

3
00:00:16,860 --> 00:00:24,960
And now you understand that every Docker image is read only and it consists of multiple layers and those

4
00:00:25,260 --> 00:00:28,770
layers could be reused between different images.

5
00:00:29,070 --> 00:00:35,880
Also, when you create new container from specific image, Docker simply creates new writable layer

6
00:00:35,880 --> 00:00:43,890
for this container and also Docker creates new process or multiple processes in specific new container.

7
00:00:43,890 --> 00:00:48,120
And this is done based on instructions included into Docker image.

8
00:00:48,940 --> 00:00:54,930
And as soon as processors in container stop, Docker stops container as well.

9
00:00:54,940 --> 00:00:59,440
There is no need to keep container running when there are no running processes.

10
00:00:59,590 --> 00:01:04,060
Also, you know that Docker containers share resources of Docker host.

11
00:01:04,090 --> 00:01:12,280
They have common, common harddrive common memory and common network access and all requests to those

12
00:01:12,280 --> 00:01:15,820
resources are performed via common Linux kernel.

13
00:01:16,760 --> 00:01:23,150
Also you know guys how to pull images from Docker hub, how to create new containers, how to remove

14
00:01:23,150 --> 00:01:26,000
stopped containers and how to remove images.

15
00:01:26,270 --> 00:01:32,090
Before moving on to further discussion of Docker features, I have decided to include a section called

16
00:01:32,090 --> 00:01:38,390
Introduction to Linux, and in that section I will cover most important features of Linux.

17
00:01:38,540 --> 00:01:40,060
I'll see you in the next section.

18
00:01:40,070 --> 00:01:40,550
Bye bye.
