1
00:00:04,820 --> 00:00:06,380
‫All right. So this is me walking through the

2
00:00:06,380 --> 00:00:10,310
‫second Compose assignment for creating a Drupal configuration.

3
00:00:10,310 --> 00:00:16,460
‫I'm in the compose assignment 2 directory, and I'm supposed to make a Docker Compose file in here.

4
00:00:18,210 --> 00:00:27,230
‫I'm going to switch over to Visual Studio Code. Make a new file.

5
00:00:27,500 --> 00:00:32,990
‫I can call it whatever I want, but the easiest way to use Docker Compose is just by calling the file

6
00:00:32,990 --> 00:00:33,760
‫docker-compose.yml.

7
00:00:33,770 --> 00:00:39,820
‫Otherwise, I have to actually specify the file every time or set an environment variable.

8
00:00:39,890 --> 00:00:43,840
‫That's kind of a pain. So, let's just do it like this. All right.

9
00:00:43,840 --> 00:00:46,720
‫It said Version 2, right,

10
00:00:46,770 --> 00:00:48,570
‫was one of the requirements.

11
00:00:49,370 --> 00:00:50,960
‫Then I type services.

12
00:00:50,990 --> 00:00:51,740
‫You'll notice this add-in,

13
00:00:51,750 --> 00:00:58,010
‫by the way. This is the Docker add-on for Visual Studio Code, which is one of the great things I love

14
00:00:58,010 --> 00:00:58,640
‫about Code.

15
00:00:58,640 --> 00:01:02,960
‫It's a great editor. It actually has abilities to, in the background, search

16
00:01:02,970 --> 00:01:07,610
‫Docker Hub, so you'll notice some things popping up as I type them.

17
00:01:07,610 --> 00:01:14,570
‫If I know I've got to do Drupal, I'm just going to call this one drupal.

18
00:01:16,740 --> 00:01:22,170
‫Then I know I have to use an image. I'm going to call it drupal because I bet you that's the name of the

19
00:01:22,170 --> 00:01:23,010
‫image.

20
00:01:25,170 --> 00:01:28,230
‫See how it actually pulls up there from Docker Hub?

21
00:01:28,490 --> 00:01:28,890
‫Pretty cool.

22
00:01:31,970 --> 00:01:42,500
‫Then I know I have to use ports to open up 8080 on my machine to...

23
00:01:42,560 --> 00:01:42,830
‫you know what?

24
00:01:42,830 --> 00:01:52,160
‫I don't know what port to use in the image. So let me actually go here and search for Drupal.

25
00:01:57,170 --> 00:02:00,980
‫Let's see...what's the documentation say?

26
00:02:03,810 --> 00:02:04,940
‫Here's an example.

27
00:02:04,950 --> 00:02:08,320
‫It looks like it's port 80 inside the container.

28
00:02:08,370 --> 00:02:11,340
‫If I wanted to confirm that, I could actually go inside.

29
00:02:11,560 --> 00:02:21,300
‫I'm just going to use latest for this example. Actually go into the Dockerfile here. It looks like it's

30
00:02:21,300 --> 00:02:25,510
‫coming from PHP Apache. There's no port command here.

31
00:02:25,740 --> 00:02:29,480
‫If I actually want to know what the port was, I can do several things.

32
00:02:29,490 --> 00:02:38,560
‫I could either go look up that FROM Image and see what the exposed command was in there. Or if I had

33
00:02:38,560 --> 00:02:39,760
‫the Drupal locally,

34
00:02:44,070 --> 00:02:50,440
‫then I did a docker image inspect drupal,

35
00:02:57,490 --> 00:02:59,380
‫expose ports. So port 80.

36
00:02:59,430 --> 00:03:04,860
‫I bet you that's what it's listening on, so I can just change that to 80.

37
00:03:08,650 --> 00:03:17,780
‫Then I know for extra credit, I'm supposed to use volumes, but I'm going to come back to that.

38
00:03:17,790 --> 00:03:25,090
‫So, the other one is going to be postgres. And then image.

39
00:03:26,520 --> 00:03:28,720
‫Oops. No.

40
00:03:33,250 --> 00:03:35,510
‫I don't want either one of those choices.

41
00:03:35,920 --> 00:03:36,790
‫All right.

42
00:03:36,850 --> 00:03:40,800
‫I don't need any ports there because it's just going to use the default when inside the network.

43
00:03:40,960 --> 00:03:44,650
‫You'll notice you only need to use ports here when you actually need to use the -p.

44
00:03:44,650 --> 00:03:50,260
‫Since these are both going to be in the same Docker network, I don't need to do anything for them

45
00:03:50,260 --> 00:03:53,320
‫to connect. They're just going to work over that network.

46
00:03:53,650 --> 00:04:04,550
‫I know the instructions said I need to set a password.

47
00:04:08,860 --> 00:04:11,010
‫I'm just going to set it to something easy for now.

48
00:04:14,530 --> 00:04:16,110
‫If I back up here.

49
00:04:16,450 --> 00:04:19,280
‫I wonder what Docker says...what Drupal says about that.

50
00:04:20,450 --> 00:04:21,990
‫I'm going to use this.

51
00:04:30,420 --> 00:04:36,580
‫If I don't use postgres user, and it defaults to the postgres...everything defaults to postgres, so

52
00:04:37,100 --> 00:04:40,580
‫the database defaults to that. The user defaults to that.

53
00:04:40,610 --> 00:04:41,860
‫I just need to set the password.

54
00:04:45,160 --> 00:04:51,090
‫I got that. I think I'm about done.

55
00:04:51,190 --> 00:04:52,680
‫Except for the volumes.

56
00:04:56,320 --> 00:04:58,170
‫Let's see what it says here. Volumes.

57
00:05:00,840 --> 00:05:01,340
‫Well, look at that.

58
00:05:01,350 --> 00:05:03,270
‫They have some examples here.

59
00:05:03,840 --> 00:05:05,490
‫So, I could just copy these.

60
00:05:08,420 --> 00:05:12,550
‫I'm just going to copy all four of them.

61
00:05:17,860 --> 00:05:23,040
‫Multiple cursors is also a pretty cool thing in Visual Studio Code.

62
00:05:23,560 --> 00:05:25,010
‫Ok. It does look good.

63
00:05:25,060 --> 00:05:29,420
‫I'm going to save this file. Ok, let's run it and see if it works.

64
00:05:36,210 --> 00:05:38,420
‫Great! If I'm going to use named volumes,

65
00:05:38,720 --> 00:05:40,970
‫I've got to do the volume section.

66
00:05:42,200 --> 00:05:44,060
‫And that's why this is a little extra credit.

67
00:05:44,080 --> 00:05:50,290
‫So, let me actually go into the documentation for Compose

68
00:05:53,710 --> 00:05:56,950
‫and look up how volumes are supposed to be there.

69
00:05:58,360 --> 00:06:05,590
‫It says that I can use the named volumes without anything else in them. Like this.

70
00:06:05,630 --> 00:06:07,420
‫So, let me try that.

71
00:06:14,860 --> 00:06:16,220
‫Oh, look at that.

72
00:06:16,320 --> 00:06:21,310
‫I just noticed I'm missing the d there.

73
00:06:21,510 --> 00:06:22,310
‫All right.

74
00:06:37,400 --> 00:06:38,490
‫Let's try again.

75
00:06:43,300 --> 00:06:46,700
‫See how it creates the networks and the volumes for it before it starts?

76
00:06:46,700 --> 00:06:47,650
‫That's pretty cool.

77
00:06:47,650 --> 00:06:48,230
‫Saves us time.

78
00:06:53,290 --> 00:06:56,810
‫All right. Looks like everything started. Let me go to localhost 8080.

79
00:06:59,590 --> 00:06:59,970
‫All right.

80
00:06:59,980 --> 00:07:00,520
‫There we go.

81
00:07:00,530 --> 00:07:03,180
‫I'm going to go through to setup real quick.

82
00:07:03,180 --> 00:07:03,560
‫Sure.

83
00:07:03,570 --> 00:07:09,490
‫Standard. I'm using postgres. The database name is postgres.

84
00:07:09,500 --> 00:07:16,130
‫If you weren't aware, you could actually go to Hub, and under the postgres,

85
00:07:18,690 --> 00:07:22,830
‫there'll be documentation about how a default database works.

86
00:07:24,320 --> 00:07:29,090
‫All the environment variables that will tell you here that if you don't specify the DB, it will actually

87
00:07:29,090 --> 00:07:30,640
‫be postgres by default.

88
00:07:36,350 --> 00:07:45,740
‫My password was mypasswd. Because I've done this before, I actually know that if I click here, it's going

89
00:07:45,740 --> 00:07:54,190
‫to tell me, 'I can't connect because I'm thinking I need to talk to localhost.' And that tells me, 'Aha! I actually

90
00:07:54,240 --> 00:07:55,710
‫have to back up here.'

91
00:07:56,150 --> 00:07:58,070
‫Re-put in my password and under advanced,

92
00:07:58,100 --> 00:08:08,940
‫it defaults to localhost. I need it to be the name of my service, which I just called postgres.

93
00:08:09,260 --> 00:08:11,100
‫I can see all the errs...not the errors

94
00:08:11,120 --> 00:08:14,780
‫but the logs in the background. It's doing stuff.

95
00:08:17,840 --> 00:08:21,710
‫It does say errors there though, doesn't it? It's working.

96
00:08:25,370 --> 00:08:31,740
‫Here's some basic information.

97
00:08:32,600 --> 00:08:40,280
‫I'm just going to put in some stuff. Let's see. We'll

98
00:08:50,720 --> 00:08:51,250
‫just call that...

99
00:08:51,260 --> 00:08:51,840
‫All right. There we go.

100
00:08:51,940 --> 00:08:54,110
‫Looks like I got a fully working Drupal website.

101
00:08:55,570 --> 00:09:01,660
‫Now that I'm done, I can actually just Control c, and I want to do a cleanup.

102
00:09:02,070 --> 00:09:05,260
‫So I want to do a down.

103
00:09:05,590 --> 00:09:09,000
‫But there's actually an option

104
00:09:10,120 --> 00:09:11,440
‫to remove the volumes.

105
00:09:11,460 --> 00:09:17,360
‫Since I don't plan on using this, I'll use down -v to remove the volumes as well. Because

106
00:09:17,360 --> 00:09:22,420
‫of course, Docker is always trying to protect volumes by default. There's no docker commands

107
00:09:23,310 --> 00:09:32,230
‫other than docker volume remove, and prune, that will actually automatically remove volumes because it's always assuming

108
00:09:32,230 --> 00:09:34,400
‫that you want to persist your data.

109
00:09:34,400 --> 00:09:35,220
‫All right.

110
00:09:35,230 --> 00:09:35,880
‫There we go.
