1 00:00:02,070 --> 00:00:04,250 Let's comment in the composer service. 2 00:00:04,250 --> 00:00:06,640 And let's now ensure that we also set up 3 00:00:06,640 --> 00:00:10,330 this container which will now be a utility container, 4 00:00:10,330 --> 00:00:14,230 which will then not only be used internally by Laravel, 5 00:00:14,230 --> 00:00:17,130 but which most importantly can be used by us, 6 00:00:17,130 --> 00:00:21,380 to also set up a Laravel application in the first place. 7 00:00:21,380 --> 00:00:25,280 For this, I'll add another Dockerfile, a custom Dockerfile, 8 00:00:25,280 --> 00:00:29,920 because I will need a base image with some fine tuning. 9 00:00:29,920 --> 00:00:32,500 So here I'll add the composer.dockerfile. 10 00:00:33,450 --> 00:00:35,380 And I'll start with a base image, 11 00:00:35,380 --> 00:00:38,340 which is the composer image. 12 00:00:38,340 --> 00:00:39,520 And that's really great. 13 00:00:39,520 --> 00:00:43,300 If you search Docker Hub, there is a composer base image, 14 00:00:43,300 --> 00:00:45,110 which basically is an image 15 00:00:45,110 --> 00:00:48,380 that has this composer tool already installed, 16 00:00:48,380 --> 00:00:49,873 which of course is awesome. 17 00:00:50,730 --> 00:00:53,450 So we can start on this composer image 18 00:00:53,450 --> 00:00:55,810 and use the latest tag, for example, 19 00:00:55,810 --> 00:00:58,560 to use the very latest image version. 20 00:00:58,560 --> 00:01:02,460 And now here's the reason why I need my custom Dockerfile, 21 00:01:02,460 --> 00:01:05,670 because I want to specify an entry point. 22 00:01:05,670 --> 00:01:08,390 Now as a side note, there would be a way of doing this 23 00:01:08,390 --> 00:01:10,750 in the docker-compose file as well. 24 00:01:10,750 --> 00:01:12,450 But I'll come back to that later. 25 00:01:12,450 --> 00:01:14,080 This is the approach I like 26 00:01:14,080 --> 00:01:15,900 because we have it is very clear, 27 00:01:15,900 --> 00:01:18,700 easy to understand Dockerfile. 28 00:01:18,700 --> 00:01:22,110 In my entry point now is the composer executable 29 00:01:22,110 --> 00:01:26,150 which exists inside of this composer image and container, 30 00:01:26,150 --> 00:01:29,310 unlike on my local host machine as I showed you before, 31 00:01:29,310 --> 00:01:31,870 and I'll add a flag which should be added 32 00:01:31,870 --> 00:01:34,270 to every command which is executed by it. 33 00:01:34,270 --> 00:01:39,270 And that's the --ignore-platform-reqs command. 34 00:01:41,250 --> 00:01:44,110 This ensures that we can run this without any warnings 35 00:01:44,110 --> 00:01:47,223 or errors even if some dependencies would be missing. 36 00:01:48,630 --> 00:01:49,830 Now very important, 37 00:01:49,830 --> 00:01:52,260 we need to set the right working directory 38 00:01:52,260 --> 00:01:57,260 and set this to /var/www/html. 39 00:01:57,900 --> 00:02:01,150 Because that is where our code will later be. 40 00:02:01,150 --> 00:02:04,030 Save this and go back to docker-compose. 41 00:02:04,030 --> 00:02:05,500 Now that we got the Dockerfile, 42 00:02:05,500 --> 00:02:08,080 we can add the build, configuration here 43 00:02:08,080 --> 00:02:12,440 to the composer service and set the context 44 00:02:12,440 --> 00:02:13,623 to ./dockerfiles. 45 00:02:16,020 --> 00:02:21,020 And set the Dockerfile option to compose.dockerfile 46 00:02:21,040 --> 00:02:23,500 because that is the Dockerfile we wanna use here 47 00:02:23,500 --> 00:02:25,520 to build this image. 48 00:02:25,520 --> 00:02:28,280 Now we need to ensure that we expose our 49 00:02:28,280 --> 00:02:31,140 source code directory to that image, 50 00:02:31,140 --> 00:02:34,860 so that this image works on our source code directory, 51 00:02:34,860 --> 00:02:37,690 and when we use it to install Laravel 52 00:02:37,690 --> 00:02:39,510 and set up a Laravel project, 53 00:02:39,510 --> 00:02:42,470 it does so in our source folder. 54 00:02:42,470 --> 00:02:43,690 And it should of course do this 55 00:02:43,690 --> 00:02:47,930 in this /var/www/html folder internally. 56 00:02:47,930 --> 00:02:50,750 So therefore, here we can add a volume 57 00:02:51,630 --> 00:02:56,630 and bind our source folder to this /var/www/html folder 58 00:02:57,700 --> 00:02:59,730 inside of the container. 59 00:02:59,730 --> 00:03:02,660 So now if we use composer to, for example, 60 00:03:02,660 --> 00:03:05,480 create a Laravel application in this folder 61 00:03:05,480 --> 00:03:06,910 inside of the container. 62 00:03:06,910 --> 00:03:11,000 This will then be mirrored back into our source folder 63 00:03:11,000 --> 00:03:13,280 on the local host machine. 64 00:03:13,280 --> 00:03:15,740 That's essentially what I also already showed you 65 00:03:15,740 --> 00:03:20,010 in the last course section with NPM and Node. 66 00:03:20,010 --> 00:03:24,330 And with this done, we can pause for a second, 67 00:03:24,330 --> 00:03:28,450 we now have our free application containers which will need 68 00:03:28,450 --> 00:03:31,560 to run the Laravel application. 69 00:03:31,560 --> 00:03:34,170 And we got this utility container which we need 70 00:03:34,170 --> 00:03:38,230 to create it, we'll need the other two utility containers 71 00:03:38,230 --> 00:03:41,390 for a certain features inside of Laravel. 72 00:03:41,390 --> 00:03:43,420 But for the moment, we can ignore them. 73 00:03:43,420 --> 00:03:45,620 And instead we can start using 74 00:03:45,620 --> 00:03:47,640 the composer utility container 75 00:03:47,640 --> 00:03:49,900 to create a Laravel application. 76 00:03:49,900 --> 00:03:52,000 And then we can see if we can launch 77 00:03:52,000 --> 00:03:53,610 this application with help 78 00:03:53,610 --> 00:03:56,180 of our free containers. 79 00:03:56,180 --> 00:03:58,083 So how do we do that?
