1 00:00:00,330 --> 00:00:06,210 So the first part of our set up is the no application, I already created the project and it's hosted 2 00:00:06,210 --> 00:00:09,400 on git repositories so you can download it from there. 3 00:00:09,810 --> 00:00:13,980 So we're going to go and clone this application, first of all. 4 00:00:14,010 --> 00:00:14,400 Right. 5 00:00:14,430 --> 00:00:15,870 So let's get the deed. 6 00:00:15,870 --> 00:00:16,370 Come in. 7 00:00:18,390 --> 00:00:29,340 And here I'm going to create a new directory, let's call it course projects, and I'm going to clone 8 00:00:29,340 --> 00:00:30,590 it right here. 9 00:00:33,840 --> 00:00:38,820 I have intelligence, so I'm going to open the app and Intelligent Ed. 10 00:00:40,950 --> 00:00:46,800 So the structure of the application is super simple, and we're going to go through the couple of files 11 00:00:46,800 --> 00:00:48,190 that the application includes. 12 00:00:48,540 --> 00:00:54,630 So first of all, the main file where the whole thing is happening is Sergius, which is an app folder. 13 00:00:54,930 --> 00:00:55,840 Let's look inside. 14 00:00:56,520 --> 00:01:02,910 So first of all, we have the express module, which we use to start the application at this port. 15 00:01:03,240 --> 00:01:10,470 And the second one we have is Peno, which is a logging library or logging module, which is, again, 16 00:01:10,470 --> 00:01:11,400 super simple. 17 00:01:11,400 --> 00:01:18,690 We just initiated right here with a log level and we just log a bunch of stuff because we need some 18 00:01:18,690 --> 00:01:23,530 information or some log data for our Lustick stack setup. 19 00:01:24,240 --> 00:01:30,390 And here in this constructor of Peno, you can actually configure the logging format, your custom fields 20 00:01:30,390 --> 00:01:30,990 and so on. 21 00:01:31,140 --> 00:01:38,160 So we are going to add configuration for timestamp format because I believe Pinole by default, we log 22 00:01:38,160 --> 00:01:40,000 in EPOP milliseconds. 23 00:01:40,000 --> 00:01:42,420 So we want a proper timestamp. 24 00:01:42,720 --> 00:01:48,620 And this takes actually a function that returns the format of a timestamp. 25 00:01:48,900 --> 00:01:52,500 And I'm actually going to paste in the one that I have. 26 00:01:54,000 --> 00:02:00,390 So this will just format into this ISO string and the name of the field will be time. 27 00:02:00,870 --> 00:02:04,830 And we're doing this to make parsing this log data easier. 28 00:02:05,610 --> 00:02:06,760 And that's it. 29 00:02:06,810 --> 00:02:08,850 This is all the application does. 30 00:02:09,040 --> 00:02:13,280 And these two dependencies right here are defined in package, trace and file. 31 00:02:13,440 --> 00:02:15,780 So we have express and Peno right here. 32 00:02:16,300 --> 00:02:22,710 I'm actually going to fixate this version so that you don't end up with different ones to make sure 33 00:02:22,710 --> 00:02:26,010 there's consistency and also to make sure there is consistency. 34 00:02:26,010 --> 00:02:27,740 Also checked in the node modules. 35 00:02:27,750 --> 00:02:30,880 So you must have it when you clone this repository. 36 00:02:30,990 --> 00:02:36,690 So this way I try to minimize your effort for setting up the applications and also to make sure you 37 00:02:36,690 --> 00:02:39,300 have the same versions of the dependencies. 38 00:02:39,510 --> 00:02:43,300 Otherwise you would have to do NPM install so you don't have to do it. 39 00:02:43,320 --> 00:02:48,830 In this case, it's the node modules or the dependencies are already there. 40 00:02:49,920 --> 00:02:50,870 So we have the scripts. 41 00:02:50,880 --> 00:02:55,920 This doesn't do anything, just EKOS and the START script is the one that starts our application. 42 00:02:55,920 --> 00:02:56,240 Right? 43 00:02:56,460 --> 00:03:02,640 So we have node come in that starts up server JS super, super simple. 44 00:03:02,880 --> 00:03:12,150 We have get ignored, which basically excludes all the non project relevant files and directories and 45 00:03:12,180 --> 00:03:13,230 that's really it. 46 00:03:13,260 --> 00:03:14,640 That's our whole application. 47 00:03:15,020 --> 00:03:21,780 In order to build the image based on this no JS application, we have a Docker file which does a couple 48 00:03:21,780 --> 00:03:22,300 of things. 49 00:03:22,440 --> 00:03:24,180 So let's go through that line by line. 50 00:03:24,480 --> 00:03:27,810 We are basing it on the node image. 51 00:03:29,490 --> 00:03:32,120 This is a tag of the node based image. 52 00:03:32,520 --> 00:03:36,960 Then we take the package, chasten in package log, Jason. 53 00:03:37,410 --> 00:03:45,750 So both of this from right here and we copied into the container filesystem. 54 00:03:45,750 --> 00:03:46,050 Right. 55 00:03:46,410 --> 00:03:53,850 So this is our host file system and we copy that, those two files inside the image under this path 56 00:03:54,300 --> 00:03:55,320 or this directory. 57 00:03:57,300 --> 00:04:01,740 If it's not there, it's going to get created, then we copy. 58 00:04:02,810 --> 00:04:09,080 What's inside the EP, so this is going to be Sergius also inside the directory, so we're going to 59 00:04:09,080 --> 00:04:10,130 end up with. 60 00:04:12,410 --> 00:04:19,820 With EPP Directory, which has Sergius packages and Package Laugesen inside, and that will be our image, 61 00:04:20,990 --> 00:04:28,970 we also said the work dear or work directory, which basically means that you tell Docteur, Hey, this 62 00:04:28,970 --> 00:04:32,000 is going to be my route directory inside the container. 63 00:04:32,480 --> 00:04:33,860 So whenever you. 64 00:04:34,990 --> 00:04:41,780 Referred to files, so, for example, server, James, you don't have to use the whole path like like 65 00:04:42,320 --> 00:04:49,370 a server J.S. you can just say submerges, which we are doing right here. 66 00:04:49,780 --> 00:04:53,050 So this is basically equivalent to this right here. 67 00:04:53,830 --> 00:05:03,700 However, before this COMEN runs, we need to execute NPM install inside the container so that the dependencies 68 00:05:04,150 --> 00:05:11,740 that we define here, Expressen, Peno get installed and the node modules directorate gets created because 69 00:05:11,740 --> 00:05:14,610 we're not copying this one inside the container. 70 00:05:14,620 --> 00:05:14,990 Right. 71 00:05:15,310 --> 00:05:21,160 So first NPM install will get executed and then node server doges. 72 00:05:22,170 --> 00:05:24,780 So we have everything we need to build that image. 73 00:05:25,140 --> 00:05:32,070 I also put the comments in the read me files so you can check that here and let's go and execute those 74 00:05:32,070 --> 00:05:32,550 comments. 75 00:05:32,820 --> 00:05:37,530 So in order to build the Docker image, I'm inside the root folder right here. 76 00:05:37,590 --> 00:05:44,530 Obviously, you can also do it on the command line, but I think it's easier in the terminal of intelligence. 77 00:05:45,240 --> 00:05:46,460 So I'm going to execute it here. 78 00:05:46,710 --> 00:05:48,270 So Docker build. 79 00:05:49,470 --> 00:05:57,810 And if you want to give our image a name instead of some anonymous name, we are going to add minus 80 00:05:57,810 --> 00:06:01,290 T, which is TEG and let's call it node EP. 81 00:06:01,770 --> 00:06:05,760 And the DOT is basically the location of Toker file. 82 00:06:05,760 --> 00:06:06,060 Right. 83 00:06:06,240 --> 00:06:10,560 And I'm executing it from route where the Docker file is. 84 00:06:10,560 --> 00:06:12,450 I can just say current directory. 85 00:06:12,810 --> 00:06:13,890 That's where Dr. Files. 86 00:06:14,190 --> 00:06:18,220 And if I execute this it should create the image. 87 00:06:18,450 --> 00:06:22,260 So here you see all those steps got executed. 88 00:06:24,380 --> 00:06:33,050 So six steps, basically, and I have an image, let's actually go to terminal and check our image there 89 00:06:33,590 --> 00:06:36,710 and I'm going to grab that because I have a lot of images. 90 00:06:37,790 --> 00:06:44,600 And here is our image that we just created, and it's ready to be pushed into a repository.
