00:00:04,170 --> 00:00:05,700
Before moving on, let me make an

3
00:00:05,730 --> 00:00:08,039
important conclusion of examples

4
00:00:08,039 --> 00:00:10,350
that we have looked at in previous

5
00:00:10,350 --> 00:00:12,780
lectures. And the most important

6
00:00:12,780 --> 00:00:15,210
conclusion is that Docker is

7
00:00:15,210 --> 00:00:16,920
capable of creation and

8
00:00:16,950 --> 00:00:18,810
modification of the files

9
00:00:18,810 --> 00:00:21,450
located on your local computer, and

10
00:00:21,450 --> 00:00:23,100
we have seen that in the last

11
00:00:23,100 --> 00:00:24,870
challenge. You have seen that

12
00:00:24,870 --> 00:00:26,640
before launch of the container,

13
00:00:26,730 --> 00:00:29,242
there was just a single file 'index.js'

14
00:00:29,242 --> 00:00:31,440
here in the 'files' folder. Let me

15
00:00:31,440 --> 00:00:33,210
clear terminal and list files

16
00:00:33,210 --> 00:00:35,670
here. And again, before launch of

17
00:00:35,670 --> 00:00:37,650
the container, there was just

18
00:00:37,650 --> 00:00:40,920
single file index.js, this one, that

19
00:00:40,950 --> 00:00:42,600
we have created manually in Visual

20
00:00:42,600 --> 00:00:45,510
Studio Code. But during execution

21
00:00:45,540 --> 00:00:47,430
of the Node.js process inside of

22
00:00:47,430 --> 00:00:49,860
the container, Docker has created

23
00:00:49,890 --> 00:00:53,121
additional files like 'myfile1.txt',

24
00:00:53,121 --> 00:00:54,930
or 'myfile2.txt'

25
00:00:55,080 --> 00:00:57,960
inside of 'files' folder on our local

26
00:00:57,960 --> 00:01:00,180
computer, it is very important.

27
00:01:00,300 --> 00:01:02,370
Again, Docker containers are

28
00:01:02,370 --> 00:01:04,500
capable of modification and

29
00:01:04,500 --> 00:01:06,900
creation of the new files on your

30
00:01:06,930 --> 00:01:09,300
local computer. And this important

31
00:01:09,300 --> 00:01:11,820
conclusion we will use in the next

32
00:01:11,820 --> 00:01:13,680
examples where we will try to

33
00:01:13,680 --> 00:01:16,650
create persistent database and work

34
00:01:16,650 --> 00:01:18,390
with the same database from

35
00:01:18,390 --> 00:01:20,160
multiple containers for example,

36
00:01:20,160 --> 00:01:21,900
MongoDB containers or Redis

37
00:01:21,900 --> 00:01:24,450
containers or MySQL containers.

38
00:01:25,020 --> 00:01:26,880
Alright, before going on with the

39
00:01:26,880 --> 00:01:28,890
next example where we will use

40
00:01:28,890 --> 00:01:31,590
'mongo' image, let me quickly clear

41
00:01:31,590 --> 00:01:33,270
our containers that we have created

42
00:01:33,270 --> 00:01:35,640
before. Let me list them, 'docker ps

43
00:01:35,640 --> 00:01:37,950
-a'. And again, we could use

44
00:01:37,950 --> 00:01:41,730
command 'docker container prune' in

45
00:01:41,730 --> 00:01:43,290
order to remove all stopped

46
00:01:43,290 --> 00:01:48,300
containers. Type Yes here, and all

47
00:01:48,300 --> 00:01:50,190
stopped containers were removed.

48
00:01:50,460 --> 00:01:51,450
And if I'll have a look at

49
00:01:51,450 --> 00:01:53,482
containers now, 'docker ps - a'

50
00:01:53,482 --> 00:01:54,960
there are no containers,

51
00:01:54,960 --> 00:01:56,910
either stopped or running.

52
00:01:57,240 --> 00:01:59,070
Wonderful. Now we are ready to go

53
00:01:59,070 --> 00:02:01,200
on, and the next let's download

54
00:02:01,230 --> 00:02:03,810
'mongo' image and launch 'mongo'

55
00:02:03,810 --> 00:02:06,018
container. I will see you next. Bye-Bye.
