WEBVTT 00:00.780 --> 00:01.613 -: In the last section, 00:01.613 --> 00:04.140 we started talking about deployment objects. 00:04.140 --> 00:07.140 Remember, a deployment is going to run and manage 00:07.140 --> 00:09.210 a set of identical pods. 00:09.210 --> 00:11.190 From this point forward throughout this course, 00:11.190 --> 00:14.400 we are no longer going to create pods ourselves manually. 00:14.400 --> 00:16.500 Instead, we're going to create deployments 00:16.500 --> 00:18.690 that will create pods for us. 00:18.690 --> 00:20.310 So deployments are appropriate for use 00:20.310 --> 00:22.773 in both a development and production environment. 00:23.640 --> 00:26.610 We're going to make a deployment that has a pod template 00:26.610 --> 00:28.980 that's going to try to create a container 00:28.980 --> 00:30.960 using the image multi-client, 00:30.960 --> 00:34.080 and we're going to make sure that port 3000 is exposed. 00:34.080 --> 00:35.700 Now the reason we're going to make a deployment 00:35.700 --> 00:37.920 with multi-client and port 3000 open, 00:37.920 --> 00:40.260 is so that we can test this out in the browser 00:40.260 --> 00:43.320 once the deployment creates our actual pod. 00:43.320 --> 00:44.520 So, to make a deployment, 00:44.520 --> 00:47.100 we're going to use the same process that we use 00:47.100 --> 00:48.660 for every other object 00:48.660 --> 00:50.760 that we're ever going to create with Kubernetes. 00:50.760 --> 00:53.250 We're going to make a configuration file, 00:53.250 --> 00:57.090 and then feed that configuration file into kubectl. 00:57.090 --> 00:59.250 So inside of my code editor, 00:59.250 --> 01:01.440 I'm gonna create a new configuration file 01:01.440 --> 01:03.840 inside of my root project directory, 01:03.840 --> 01:05.190 and I'll give this file a name 01:05.190 --> 01:09.003 of client-deployment.emo. 01:11.730 --> 01:12.780 And then inside this file, 01:12.780 --> 01:14.700 we're gonna add all of our configuration 01:14.700 --> 01:17.610 to describe this new deployment that we're making. 01:17.610 --> 01:18.450 We're going to write out 01:18.450 --> 01:20.400 all the configuration together right now, 01:20.400 --> 01:21.660 and then we'll talk about the purpose 01:21.660 --> 01:23.763 of every line immediately after that. 01:24.600 --> 01:28.020 So I'll get started by writing out API version, 01:28.020 --> 01:30.513 and I'll say apps/V1. 01:31.470 --> 01:34.740 I'll specify kind of deployment. 01:34.740 --> 01:35.850 So these two lines right here. 01:35.850 --> 01:37.350 I bet you can guess what's going on. 01:37.350 --> 01:39.750 We are saying that we want to use a object 01:39.750 --> 01:44.010 that is defined inside the API version of apps/V1, 01:44.010 --> 01:45.390 and the specific type of object 01:45.390 --> 01:48.120 that we want to create is a deployment. 01:48.120 --> 01:50.853 Next up, we'll put down our metadata section, 01:52.200 --> 01:55.503 and we'll give the thing a name of client-deployment. 01:56.910 --> 01:59.220 Then we'll do our spec after that. 01:59.220 --> 02:00.300 For the spec, 02:00.300 --> 02:02.523 we'll say replicas is one. 02:03.600 --> 02:07.170 We'll add on a selector with match labels, 02:07.170 --> 02:10.113 and a component web property lexo. 02:12.330 --> 02:13.320 I'll then un-indent 02:13.320 --> 02:15.930 so I now only have one indent right here. 02:15.930 --> 02:17.073 I'll say template. 02:18.690 --> 02:20.373 I'll put in metadata, 02:21.750 --> 02:22.623 labels, 02:24.780 --> 02:26.343 component web. 02:27.240 --> 02:28.620 I'm going to un-indent again 02:28.620 --> 02:32.643 so that I'm on the same indentation layer as metadata. 02:33.600 --> 02:35.520 I'll say spec, 02:35.520 --> 02:36.573 containers, 02:37.500 --> 02:39.450 and we'll define the list of containers 02:39.450 --> 02:41.400 that we want created with every pod 02:41.400 --> 02:43.560 that is controlled by this deployment. 02:43.560 --> 02:45.270 So this is a array entry. 02:45.270 --> 02:47.580 So I'll put in my little dash like so. 02:47.580 --> 02:49.920 And I'll say that I want a pod that has a name, 02:49.920 --> 02:52.980 or so be a container in this pod with a name of client. 02:52.980 --> 02:57.980 I want it to run the image of my docker ID/multi client. 02:58.830 --> 03:00.930 And then finally we'll set up that port mapping. 03:00.930 --> 03:02.490 So I'll say ports 03:02.490 --> 03:07.023 with a container port of 3000 like so. 03:08.430 --> 03:10.320 Okay. So, something's inside this file 03:10.320 --> 03:11.610 might look a little bit familiar. 03:11.610 --> 03:12.540 Let's take a quick pause. 03:12.540 --> 03:13.770 We're gonna come back the next section 03:13.770 --> 03:16.440 and start breaking this thing down line by line. 03:16.440 --> 03:18.090 So I'll see you in just a minute.
