2
00:00:04,470 --> 00:00:06,060
All right in the previous lecture I

3
00:00:06,060 --> 00:00:07,410
have explained you differences

4
00:00:07,410 --> 00:00:09,150
between management commands and

5
00:00:09,150 --> 00:00:11,280
commands; and you know that there

6
00:00:11,280 --> 00:00:12,780
are pairs of commands that are

7
00:00:12,780 --> 00:00:14,670
called alternative commands; and you

8
00:00:14,670 --> 00:00:16,649
are able to use either alternative

9
00:00:16,680 --> 00:00:18,510
short command or long command with

10
00:00:18,510 --> 00:00:19,950
management command. For example,

11
00:00:19,980 --> 00:00:22,620
'docker ps' and 'docker container ls'

12
00:00:22,740 --> 00:00:24,660
is pair of alternative commands.

13
00:00:25,140 --> 00:00:27,270
Alright, let's now proceed and I'll

14
00:00:27,270 --> 00:00:29,040
tell you now about most popular

15
00:00:29,040 --> 00:00:30,900
commands that are used for

16
00:00:30,930 --> 00:00:32,700
containers management in Docker.

17
00:00:33,060 --> 00:00:34,950
First command, 'docker run' is

18
00:00:34,980 --> 00:00:36,840
short version of command 'docker

19
00:00:36,840 --> 00:00:39,450
container run'. This command starts a

20
00:00:39,510 --> 00:00:42,120
new container, and you are able to

21
00:00:42,120 --> 00:00:43,650
create multiple containers

22
00:00:43,680 --> 00:00:45,690
simultaneously on the same Docker

23
00:00:45,690 --> 00:00:48,600
computer. Next command 'docker stop',

24
00:00:48,750 --> 00:00:50,550
this command stops running

25
00:00:50,550 --> 00:00:53,760
container. And when this command is

26
00:00:53,760 --> 00:00:55,770
executed, Docker basically sends

27
00:00:55,800 --> 00:00:58,590
under the hood SIGTERM signal

28
00:00:58,620 --> 00:01:00,210
to specific process inside of the

29
00:01:00,210 --> 00:01:02,160
container; and if that process

30
00:01:02,190 --> 00:01:04,410
reacts to SIGTERM command, then

31
00:01:04,410 --> 00:01:06,000
container will be stopped pretty

32
00:01:06,000 --> 00:01:08,820
fast. But sometimes processes don't

33
00:01:08,820 --> 00:01:10,830
react to SIGTERM signal; and in

34
00:01:10,830 --> 00:01:12,690
such case, after entering the

35
00:01:12,690 --> 00:01:14,250
'docker stop' command, you'll need

36
00:01:14,250 --> 00:01:16,650
to wait 10 seconds, and afterwards

37
00:01:16,680 --> 00:01:18,720
Docker will fall back to 'docker

38
00:01:18,720 --> 00:01:20,940
kill' command; and this command

39
00:01:20,970 --> 00:01:24,000
actually sends a SIGKILL signal to

40
00:01:24,000 --> 00:01:25,650
specific process; and

41
00:01:25,680 --> 00:01:27,480
corresponding container terminates

42
00:01:27,540 --> 00:01:30,480
very fast. All right next command

43
00:01:30,510 --> 00:01:32,760
is 'docker rm'. With this command you

44
00:01:32,760 --> 00:01:34,590
are able to remove a specific

45
00:01:34,590 --> 00:01:36,870
container that was already stopped.

46
00:01:37,140 --> 00:01:39,420
You're not able to remove a running

47
00:01:39,420 --> 00:01:41,610
container, you need to stop it first,

48
00:01:41,610 --> 00:01:43,710
and only afterwards remove with

49
00:01:43,710 --> 00:01:46,290
'docker rm' command. Next command,

50
00:01:46,320 --> 00:01:49,050
'docker ps', lists running containers,

51
00:01:49,140 --> 00:01:50,340
and this command is already

52
00:01:50,340 --> 00:01:52,470
familiar to you, and I have used it

53
00:01:52,470 --> 00:01:54,510
in a previous lecture. Alternative

54
00:01:54,510 --> 00:01:56,310
long version is 'docker container

55
00:01:56,310 --> 00:01:59,280
ls'. And last command is 'docker ps

56
00:01:59,310 --> 00:02:02,040
-a'. With '-a' option

57
00:02:02,070 --> 00:02:05,190
supplied to 'ps' command you're able

58
00:02:05,190 --> 00:02:07,200
to list all containers including

59
00:02:07,230 --> 00:02:09,960
stopped containers. Please notice

60
00:02:09,960 --> 00:02:11,610
that instead of '-a' option, you're

61
00:02:11,610 --> 00:02:14,100
able to use also long version of

62
00:02:14,100 --> 00:02:17,220
this option, '--all'. That's all

63
00:02:17,220 --> 00:02:18,960
for most popular container

64
00:02:18,960 --> 00:02:21,030
management commands. And next let

65
00:02:21,030 --> 00:02:22,770
me briefly overview most popular

66
00:02:22,800 --> 00:02:24,720
images commands. 'docker pull'

67
00:02:24,720 --> 00:02:27,150
command is used for pulling image

68
00:02:27,180 --> 00:02:29,610
from Docker Hub. And if

69
00:02:29,640 --> 00:02:31,650
corresponding image already exists

70
00:02:31,680 --> 00:02:33,840
in your local cache, then no pull

71
00:02:33,870 --> 00:02:35,370
will be performed, and you will be

72
00:02:35,370 --> 00:02:37,020
able to simply reuse currently

73
00:02:37,080 --> 00:02:38,970
located in your local cache image.

74
00:02:39,720 --> 00:02:42,000
Next command 'docker images' lists

75
00:02:42,030 --> 00:02:44,640
downloaded images that were already

76
00:02:44,670 --> 00:02:46,470
downloaded, pulled from Docker hub

77
00:02:46,500 --> 00:02:49,950
to your local cache. 'docker rmi',

78
00:02:50,010 --> 00:02:52,560
removes image or images from your

79
00:02:52,590 --> 00:02:54,810
local cache. If you don't need some

80
00:02:54,840 --> 00:02:56,610
images, you could simply use this

81
00:02:56,610 --> 00:02:58,320
command in order to free up some

82
00:02:58,320 --> 00:03:00,900
space on your local setup. And

83
00:03:00,900 --> 00:03:02,610
finally, example of additional

84
00:03:02,610 --> 00:03:04,170
commands that you could use along

85
00:03:04,200 --> 00:03:06,360
with images is 'docker build.'.

86
00:03:06,570 --> 00:03:08,580
With this command you're able to

87
00:03:08,580 --> 00:03:11,190
create new custom image based on

88
00:03:11,190 --> 00:03:13,620
created Dockerfile. And we will

89
00:03:13,620 --> 00:03:14,940
talk about that in one of the next

90
00:03:14,940 --> 00:03:16,950
sections when I'll explain you how

91
00:03:16,950 --> 00:03:19,230
to create custom images, and how to

92
00:03:19,230 --> 00:03:22,050
push them to your account at Docker

93
00:03:22,050 --> 00:03:24,930
Hub. Great, that's all for most

94
00:03:24,930 --> 00:03:27,360
popular commands that are used for

95
00:03:27,360 --> 00:03:29,100
management of images, for pulling

96
00:03:29,100 --> 00:03:30,990
images, listing images, and removing

97
00:03:31,020 --> 00:03:33,480
images. And next let's start some

98
00:03:33,480 --> 00:03:35,760
practice activities, and let's pull

99
00:03:35,790 --> 00:03:37,590
first image from Docker Hub, and

100
00:03:37,590 --> 00:03:39,120
create container based on that

101
00:03:39,150 --> 00:03:40,620
image. I'll see you in the next

102
00:03:40,620 --> 00:03:41,600
lecture. Bye-Bye.
