1 00:00:02,120 --> 00:00:03,400 In docker compose, 2 00:00:03,400 --> 00:00:06,470 let's continue with the artisan container. 3 00:00:06,470 --> 00:00:09,960 We need the artisan tool to run certain level commands. 4 00:00:09,960 --> 00:00:12,090 For example, to populate the database 5 00:00:12,090 --> 00:00:13,463 with some initial data. 6 00:00:14,490 --> 00:00:18,350 Now, the artisan command, again, needs a custom docker file. 7 00:00:18,350 --> 00:00:21,830 However, I will simply use the PHP docker file here 8 00:00:21,830 --> 00:00:25,920 because I just need the same setup as we have it in here. 9 00:00:25,920 --> 00:00:28,610 So we can add the build configuration here 10 00:00:28,610 --> 00:00:32,070 or simply copy the one from the PHP container 11 00:00:32,070 --> 00:00:34,630 and add it here for artisan. 12 00:00:34,630 --> 00:00:37,570 Because it needs PHP to execute code. 13 00:00:37,570 --> 00:00:40,840 Artisan is a level command built with PHP. 14 00:00:40,840 --> 00:00:43,400 So it needs PHP to do that. 15 00:00:43,400 --> 00:00:45,820 Now, in addition, it needs volumes 16 00:00:45,820 --> 00:00:49,130 and there specifically it again, needs our source code. 17 00:00:49,130 --> 00:00:52,230 Because it is executed on our source code. 18 00:00:52,230 --> 00:00:56,160 We do things with our source code with that command. 19 00:00:56,160 --> 00:01:00,140 So we expose the source directory on our local host machine 20 00:01:00,140 --> 00:01:04,900 queue to good old /var/www/html folder 21 00:01:04,900 --> 00:01:07,840 inside of this container, 22 00:01:07,840 --> 00:01:10,583 because that's where our application will reside. 23 00:01:11,450 --> 00:01:13,670 And now I'll show you something interesting 24 00:01:13,670 --> 00:01:15,670 which I haven't shown you before. 25 00:01:15,670 --> 00:01:19,920 You can actually also set certain settings 26 00:01:19,920 --> 00:01:22,320 which you set in a docker file normally, 27 00:01:22,320 --> 00:01:24,320 inside of a docker-compose file 28 00:01:24,320 --> 00:01:26,970 to essentially override the settings 29 00:01:26,970 --> 00:01:28,670 inside of the docker file. 30 00:01:28,670 --> 00:01:32,700 And here I'm using the PHP docker file because I want PHP. 31 00:01:32,700 --> 00:01:35,540 I'm also happy with this working directory 32 00:01:35,540 --> 00:01:38,570 but I also want to add an entry point. 33 00:01:38,570 --> 00:01:42,260 And in the PHP image, we don't have an entry point. 34 00:01:42,260 --> 00:01:45,760 Simply because this PHP container, is in the end used 35 00:01:45,760 --> 00:01:49,380 by nginx to funnel individual files through it. 36 00:01:49,380 --> 00:01:51,430 So it's used like a utility container 37 00:01:51,430 --> 00:01:53,440 for nginx you could say. 38 00:01:53,440 --> 00:01:57,200 This is all good, but now I need to run my own command. 39 00:01:57,200 --> 00:02:00,240 And I wanna specify this as an entry point. 40 00:02:00,240 --> 00:02:02,800 We could create a separate docker file, 41 00:02:02,800 --> 00:02:07,090 but we can also simply add the entry point option here 42 00:02:07,090 --> 00:02:08,600 in docker compose. 43 00:02:08,600 --> 00:02:10,410 And this allows us to override 44 00:02:10,410 --> 00:02:12,350 or add if it doesn't exist yet 45 00:02:12,350 --> 00:02:15,140 the entry point in a docker file. 46 00:02:15,140 --> 00:02:16,834 So here we then specify it just 47 00:02:16,834 --> 00:02:19,600 as we would to do it inside of the docker file. 48 00:02:19,600 --> 00:02:22,157 And here I want to execute PHP. 49 00:02:23,340 --> 00:02:26,080 So this tool the executable, 50 00:02:26,080 --> 00:02:29,490 which is set up by this PHP base image. 51 00:02:29,490 --> 00:02:32,680 And I wanna execute a certain file with PHP. 52 00:02:32,680 --> 00:02:34,300 And that file can be found 53 00:02:34,300 --> 00:02:38,497 in the /var/www/html artisan folder. 54 00:02:39,440 --> 00:02:41,780 Or to be precise in the HTML folder 55 00:02:41,780 --> 00:02:43,860 and then it's the artisan file. 56 00:02:43,860 --> 00:02:47,090 And we can see this file in the source folder. 57 00:02:47,090 --> 00:02:48,920 It's this file here. 58 00:02:48,920 --> 00:02:51,650 This is a PHP file, but when you execute it 59 00:02:51,650 --> 00:02:55,300 it runs a utility program, which can do a lot of stuff. 60 00:02:55,300 --> 00:02:57,830 It's part of the level framework. 61 00:02:57,830 --> 00:03:01,470 And we're executing this file inside of the container 62 00:03:01,470 --> 00:03:04,280 with help of PHP and this PHP image. 63 00:03:04,280 --> 00:03:06,880 And we're adding this entry point to the image 64 00:03:06,880 --> 00:03:09,930 since it doesn't exist in our docker file. 65 00:03:09,930 --> 00:03:12,320 And we also don't want to add it here 66 00:03:12,320 --> 00:03:14,830 because we use this PHP docker file 67 00:03:14,830 --> 00:03:16,550 all to folder PHP container. 68 00:03:16,550 --> 00:03:19,323 And here, we don't want the entry point. 69 00:03:20,170 --> 00:03:23,680 So this is the setup we need for artisan here. 70 00:03:23,680 --> 00:03:27,160 Now with that, we already finished this container 71 00:03:27,160 --> 00:03:29,370 and let's also finish NPM now. 72 00:03:29,370 --> 00:03:34,300 NPM is quite simple, here I'll use the node image 73 00:03:34,300 --> 00:03:36,790 and there let's say node 14. 74 00:03:36,790 --> 00:03:39,370 And now we could either write a docker file 75 00:03:39,370 --> 00:03:42,480 to set the working directory and the entry point 76 00:03:42,480 --> 00:03:45,670 or we use our newly gained knowledge that we can add 77 00:03:45,670 --> 00:03:48,710 or override certain things here in docker compose. 78 00:03:48,710 --> 00:03:50,630 And we can utilize this to set 79 00:03:50,630 --> 00:03:54,100 the working directory here as well in docker compose. 80 00:03:54,100 --> 00:03:55,420 And that's what I mentioned earlier. 81 00:03:55,420 --> 00:03:57,050 You can do this here as well. 82 00:03:57,050 --> 00:04:01,030 I prefer docker files, but to show both I'll now do it here. 83 00:04:01,030 --> 00:04:05,050 And I'll set the working directory to /var/www/html 84 00:04:05,050 --> 00:04:08,130 as so often and enter entry point, 85 00:04:08,130 --> 00:04:10,090 which in this case is NPM. 86 00:04:10,090 --> 00:04:12,440 So that we expose this NPM command 87 00:04:12,440 --> 00:04:15,410 from inside our image, based on this node image 88 00:04:15,410 --> 00:04:17,510 so that we can use this NPM container 89 00:04:17,510 --> 00:04:19,803 to run NPM commands, inside of it. 90 00:04:20,829 --> 00:04:25,200 And now, I just also want to add a volume here. 91 00:04:25,200 --> 00:04:28,090 Because, I again, want to of course do all of that 92 00:04:28,090 --> 00:04:31,530 on my source code folder, and therefore bind that 93 00:04:31,530 --> 00:04:36,530 to the /var/www/html folder inside of the container. 94 00:04:36,830 --> 00:04:38,963 Same logic as for artisan. 95 00:04:40,130 --> 00:04:42,880 And now with that, we're done. 96 00:04:42,880 --> 00:04:44,700 Now, make sure that you got 97 00:04:44,700 --> 00:04:47,950 your application servers up and running. 98 00:04:47,950 --> 00:04:50,480 And let's now try the artisan command. 99 00:04:50,480 --> 00:04:52,780 And for this, we can use docker-compose run 100 00:04:52,780 --> 00:04:55,823 and then run the artisan container. 101 00:04:57,070 --> 00:04:59,740 Which internally then runs this artisan file 102 00:04:59,740 --> 00:05:00,573 with PHP 103 00:05:01,897 --> 00:05:03,720 at --rm though. 104 00:05:03,720 --> 00:05:06,000 So that it's removed and we're done. 105 00:05:06,000 --> 00:05:08,720 And now run the migrate command. 106 00:05:08,720 --> 00:05:11,900 Which is one of the artisan command's level supports. 107 00:05:11,900 --> 00:05:14,400 This will write some data to the database 108 00:05:14,400 --> 00:05:16,120 and it will therefore also check 109 00:05:16,120 --> 00:05:18,810 whether this database set up works. 110 00:05:18,810 --> 00:05:21,590 So let's hit enter, and this looks good. 111 00:05:21,590 --> 00:05:25,020 It's migrating and it migrated successfully. 112 00:05:25,020 --> 00:05:26,210 And this wouldn't work 113 00:05:26,210 --> 00:05:29,040 if we wouldn't have a database connection. 114 00:05:29,040 --> 00:05:31,740 So, with that, we also tested this. 115 00:05:31,740 --> 00:05:34,740 We're not going to test NPM here, but it should work. 116 00:05:34,740 --> 00:05:37,640 And we now have a nice setup here 117 00:05:37,640 --> 00:05:40,380 for a level PHP application. 118 00:05:40,380 --> 00:05:43,520 Yes, this definitely is a more complex setup 119 00:05:43,520 --> 00:05:45,830 but that's also the idea behind the course. 120 00:05:45,830 --> 00:05:49,440 Learn the basics and then also see more complex things 121 00:05:49,440 --> 00:05:50,673 being built with that. 122 00:05:51,610 --> 00:05:54,080 Now, when you build something like this on your own, 123 00:05:54,080 --> 00:05:55,350 it's totally normal 124 00:05:55,350 --> 00:05:57,650 that you build something like that step by step 125 00:05:57,650 --> 00:06:00,400 by googling, finding other solutions, 126 00:06:00,400 --> 00:06:01,890 taking courses like this 127 00:06:01,890 --> 00:06:04,350 and eventually you'll get to the point 128 00:06:04,350 --> 00:06:07,490 where you can build something like this totally on your own. 129 00:06:07,490 --> 00:06:10,660 Obviously, it also helps if you know level and PHP 130 00:06:10,660 --> 00:06:13,130 because you then know the building blocks you'll need 131 00:06:13,130 --> 00:06:14,380 like composer. 132 00:06:14,380 --> 00:06:17,500 If you don't know that, you obviously also have no chance 133 00:06:17,500 --> 00:06:19,290 of knowing that you need to add it. 134 00:06:19,290 --> 00:06:20,960 So don't be discouraged by that 135 00:06:20,960 --> 00:06:22,823 if you don't know PHP or level.
