[Intro Music]

2
00:00:04,260 --> 00:00:06,060
Now there are two containers up and

3
00:00:06,060 --> 00:00:07,740
running. And we see here that

4
00:00:07,770 --> 00:00:09,390
'docker-compose' process is also

5
00:00:09,390 --> 00:00:11,670
running. And let's first interrupt

6
00:00:11,670 --> 00:00:12,870
this process by pressing key

7
00:00:12,870 --> 00:00:15,630
combination Ctrl+C like that. You

8
00:00:15,630 --> 00:00:17,370
see that two containers are now

9
00:00:17,370 --> 00:00:19,650
stopping, this one and this one.

10
00:00:19,890 --> 00:00:22,350
Containers were stopped. And if I

11
00:00:22,350 --> 00:00:24,480
enter 'docker ps' now, I will see

12
00:00:24,480 --> 00:00:26,040
empty output, because

13
00:00:26,040 --> 00:00:27,810
'docker-compose' has stopped both

14
00:00:27,810 --> 00:00:30,570
containers. Now let's try to rerun

15
00:00:30,600 --> 00:00:32,130
both containers using the same

16
00:00:32,130 --> 00:00:33,960
command as before 'docker-compose

17
00:00:33,990 --> 00:00:35,910
up', but now let's run them in

18
00:00:35,910 --> 00:00:37,890
background. And first let's have a

19
00:00:37,890 --> 00:00:39,570
look at all options that you have

20
00:00:39,630 --> 00:00:42,300
in 'docker-compose up' command. For

21
00:00:42,300 --> 00:00:43,890
that, please type 'docker-compose

22
00:00:43,950 --> 00:00:46,980
up --help'. Here you'll find a list

23
00:00:46,980 --> 00:00:49,050
of options. In this options list,

24
00:00:49,080 --> 00:00:51,060
you could find option '--build'

25
00:00:51,240 --> 00:00:53,310
that allows you to rebuild all

26
00:00:53,340 --> 00:00:54,480
images defined in the

27
00:00:54,480 --> 00:00:56,880
'docker-compose' file. And also at

28
00:00:56,880 --> 00:00:58,740
the beginning of this options list,

29
00:00:58,830 --> 00:01:00,390
you should find option that is

30
00:01:00,390 --> 00:01:04,349
called '-d', or '--detach'; and

31
00:01:04,379 --> 00:01:06,239
this will run all containers

32
00:01:06,269 --> 00:01:07,830
defined in the 'docker-compose'

33
00:01:07,830 --> 00:01:10,440
file in detached mode, and that's

34
00:01:10,470 --> 00:01:12,720
what we will try right now. Let's

35
00:01:12,720 --> 00:01:13,830
clear terminal and type

36
00:01:13,860 --> 00:01:18,060
'docker-compose up -d', this stands

37
00:01:18,060 --> 00:01:20,220
for detached mode. Let's go ahead,

38
00:01:20,970 --> 00:01:22,800
Starting both containers,

39
00:01:23,160 --> 00:01:24,930
'images-gallery_api_1' and

40
00:01:24,960 --> 00:01:28,380
'images-gallery_frontend_1'. 'done'

41
00:01:29,100 --> 00:01:31,590
and 'done' here. Now, I returned to

42
00:01:31,590 --> 00:01:33,120
the command prompt, and I could

43
00:01:33,120 --> 00:01:35,130
continue doing other operations.

44
00:01:35,340 --> 00:01:37,020
Let's have a look at currently running

45
00:01:37,020 --> 00:01:39,960
containers, 'docker ps', and I see

46
00:01:39,990 --> 00:01:42,000
both containers that are up and

47
00:01:42,000 --> 00:01:45,000
running same as before, 'api', and

48
00:01:45,030 --> 00:01:48,030
'frontend' containers. Great. Let's

49
00:01:48,030 --> 00:01:49,860
now verify whether our application

50
00:01:49,860 --> 00:01:52,500
works as before. Refresh page here,

51
00:01:53,400 --> 00:01:56,160
search for something and they both

52
00:01:56,160 --> 00:01:59,100
result same as before. Great. Now

53
00:01:59,100 --> 00:02:01,080
let me show you how you're able to

54
00:02:01,080 --> 00:02:03,240
stop those containers by using

55
00:02:03,300 --> 00:02:05,190
'docker-compose down' command.

56
00:02:05,670 --> 00:02:07,140
Let's clear terminal and type

57
00:02:07,140 --> 00:02:10,440
'docker-compose down'. And it's

58
00:02:10,440 --> 00:02:11,940
important to mention that you need

59
00:02:11,940 --> 00:02:13,710
to run those commands like

60
00:02:13,740 --> 00:02:15,270
'docker-compose down' or

61
00:02:15,300 --> 00:02:17,310
'docker-compose up' in specific

62
00:02:17,310 --> 00:02:19,080
folder where there was

63
00:02:19,080 --> 00:02:21,390
corresponding 'docker-compose.yml'

64
00:02:21,390 --> 00:02:23,610
file. Okay, let's bring down both

65
00:02:23,610 --> 00:02:25,980
containers. Both containers are

66
00:02:25,980 --> 00:02:27,210
being stopped at the moment.

67
00:02:27,960 --> 00:02:30,390
Stopped. Also those containers were

68
00:02:30,390 --> 00:02:32,970
removed. And also network that was

69
00:02:32,970 --> 00:02:34,560
created specifically for

70
00:02:34,560 --> 00:02:35,760
communication between those

71
00:02:35,760 --> 00:02:37,740
containers was removed as well.

72
00:02:37,830 --> 00:02:38,820
Network Name is

73
00:02:38,850 --> 00:02:40,980
'images-gallery_default'. Let's

74
00:02:40,980 --> 00:02:42,810
start those containers back again,

75
00:02:43,140 --> 00:02:46,410
'docker-compose up -d', detach

76
00:02:46,410 --> 00:02:51,000
mode. Creating network. Creating

77
00:02:51,000 --> 00:02:53,640
containers. Notice that we don't

78
00:02:53,670 --> 00:02:55,950
build new images because images are

79
00:02:55,950 --> 00:02:59,430
already built. 'done' here; and 'done'

80
00:02:59,430 --> 00:03:02,370
here. And containers are now again

81
00:03:02,400 --> 00:03:05,190
up and running. Great. Now let's

82
00:03:05,190 --> 00:03:06,480
commit the changes made in

83
00:03:06,510 --> 00:03:08,010
'docker-compose' file. It is

84
00:03:08,010 --> 00:03:10,110
actually its initial version. Let's

85
00:03:10,110 --> 00:03:12,120
go to source control, and here our

86
00:03:12,120 --> 00:03:13,890
commit message will be 'Initial

87
00:03:14,010 --> 00:03:17,760
version of the docker-compose' like

88
00:03:17,760 --> 00:03:20,340
that. Let's commit changes, Changes

89
00:03:20,340 --> 00:03:22,050
committed. And now let's proceed

90
00:03:22,080 --> 00:03:24,150
and next I'll explain to you how to

91
00:03:24,150 --> 00:03:27,090
map volumes to the containers and

92
00:03:27,090 --> 00:03:29,040
you'll understand why we actually

93
00:03:29,040 --> 00:03:31,080
need to do that. I'll see you guys

94
00:03:31,100 --> 00:03:32,100
just in a bit.
