WEBVTT 00:00.780 --> 00:01.950 -: We've now successfully learned 00:01.950 --> 00:03.780 how to create a Docker image 00:03.780 --> 00:06.450 in order to run Redis on our machine locally. 00:06.450 --> 00:07.470 But there's still a lot to learn 00:07.470 --> 00:10.170 about creating image in running Docker applications. 00:10.170 --> 00:12.990 So in this section we're gonna kick off a new project. 00:12.990 --> 00:14.250 The goal of this project 00:14.250 --> 00:17.820 is to create a tiny Node.js web application, 00:17.820 --> 00:19.740 wrap it inside of a Docker container, 00:19.740 --> 00:22.470 and then be able to access that web application 00:22.470 --> 00:25.590 from a browser running on your local machine. 00:25.590 --> 00:27.840 We're not gonna worry about deploying this app right now. 00:27.840 --> 00:30.270 We're just focused on getting Node.js to work 00:30.270 --> 00:32.610 inside of a Docker container. 00:32.610 --> 00:34.980 Let me first begin by showing you a quick outline 00:34.980 --> 00:38.010 of some of the steps that we're going to go through. 00:38.010 --> 00:39.090 So the first thing we have to do 00:39.090 --> 00:42.330 is create an actual Node.js web application. 00:42.330 --> 00:45.060 Now, if you don't have any experience with Node.js 00:45.060 --> 00:46.620 and you are more of a Java person 00:46.620 --> 00:49.620 or Ruby or whatever it might be, that is totally fine. 00:49.620 --> 00:50.730 The code that we're gonna write 00:50.730 --> 00:53.220 for the JavaScript side of things is totally optional. 00:53.220 --> 00:55.470 So you can either watch the video 00:55.470 --> 00:56.970 where we will put together the server, 00:56.970 --> 00:58.770 or you can entirely skip it 00:58.770 --> 01:00.840 and you can just download the single file 01:00.840 --> 01:03.210 or one or two files that you're going to need. 01:03.210 --> 01:05.310 So if you don't know anything about Node.js, 01:05.310 --> 01:06.813 no problem whatsoever. 01:07.680 --> 01:09.540 After we create the Node.js web app, 01:09.540 --> 01:11.940 we'll then author a Docker file. 01:11.940 --> 01:14.850 We're gonna make a Docker file to create an image 01:14.850 --> 01:17.730 that is going to be used to run our web server 01:17.730 --> 01:19.530 inside of a container. 01:19.530 --> 01:21.720 So we're going to build the image from the Docker file. 01:21.720 --> 01:24.600 We will run the image as a container on our local machine 01:24.600 --> 01:25.740 and then we will make sure 01:25.740 --> 01:28.890 that we are able to connect to that running web application 01:28.890 --> 01:31.233 inside the container from our browser. 01:32.310 --> 01:35.880 Now, last thing I wanna mention here, and this might be 01:35.880 --> 01:37.530 something that makes you a little bit unhappy, 01:37.530 --> 01:40.170 but I'm just gonna throw a disclaimer out here. 01:40.170 --> 01:42.600 We're going to do some things in this project 01:42.600 --> 01:44.280 a little bit wrong. 01:44.280 --> 01:46.230 So when we put together our Docker file, 01:46.230 --> 01:48.510 we're going to make a couple of mistakes. 01:48.510 --> 01:50.820 And we're doing this very much on purpose 01:50.820 --> 01:52.530 because these are going to be some mistakes 01:52.530 --> 01:54.330 that I really expect you to make 01:54.330 --> 01:57.660 when you start working on Docker on your own projects. 01:57.660 --> 01:59.700 So I want you to see these mistakes. 01:59.700 --> 02:01.230 I want you to see the error messages, 02:01.230 --> 02:03.690 and I want you to learn how to fix them. 02:03.690 --> 02:05.730 So just quick disclaimer, you know, again, 02:05.730 --> 02:07.920 we're gonna do things just a little bit wrong. 02:07.920 --> 02:08.753 Don't worry. 02:08.753 --> 02:10.920 I will be very clear when we come across an error, 02:10.920 --> 02:13.020 and I will say very, very clearly, 02:13.020 --> 02:14.340 hey, we did this on purpose, 02:14.340 --> 02:16.530 here's the mistake, and here's how to fix it. 02:16.530 --> 02:18.210 I know that sometimes in a tutorial, 02:18.210 --> 02:21.180 it's really frustrating when things are done incorrectly. 02:21.180 --> 02:22.013 I'm totally aware of that 02:22.013 --> 02:23.310 so I'm gonna make sure that these errors 02:23.310 --> 02:26.430 are as distinct and highlighted as possible. 02:26.430 --> 02:28.650 All right, so with that in mind, let's take a quick break. 02:28.650 --> 02:30.420 When we come back, the next section, we're gonna start 02:30.420 --> 02:33.300 putting together this Node.js web application. 02:33.300 --> 02:34.950 So I'll see you in just a minute.
