WEBVTT 00:00.091 --> 00:02.280 -: In this section, we're going to update 00:02.280 --> 00:04.200 our Config files for the multi-server 00:04.200 --> 00:06.660 and the multi-worker and add all these different 00:06.660 --> 00:07.830 environment variables. 00:07.830 --> 00:10.470 Again, we're going to leave off the PGPASSWORD 00:10.470 --> 00:11.520 for right now, we're not gonna 00:11.520 --> 00:12.660 worry about that one just yet, 00:12.660 --> 00:14.970 we're going to come back to it at the very end. 00:14.970 --> 00:16.290 All right, so, we're going to first open up 00:16.290 --> 00:18.570 our multi-worker config file, 00:18.570 --> 00:19.620 the deployment for it, 00:19.620 --> 00:21.330 and we're going to add in a little bit 00:21.330 --> 00:23.730 of configuration to that. 00:23.730 --> 00:25.080 So, inside of my code editor, 00:25.080 --> 00:27.273 I will find the Worker Deployment file. 00:28.200 --> 00:29.760 And inside of here, I'm going to scroll down 00:29.760 --> 00:33.900 to the pod template. So here is my template section. 00:33.900 --> 00:36.750 And then I'm going to find the container definition, 00:36.750 --> 00:39.480 and we're going to add on a set of environment variables 00:39.480 --> 00:41.580 that are going to be passed into this container 00:41.580 --> 00:44.280 when it is created inside of the pod. 00:44.280 --> 00:46.530 And so, on the container definition, I'll add on 00:46.530 --> 00:49.753 and ".env", environment version .env key. 00:49.753 --> 00:52.230 ".Env" is short for environment variables. 00:52.230 --> 00:54.360 And we're going to designate a couple here. 00:54.360 --> 00:56.148 So, .env is going to receive an array, 00:56.148 --> 00:59.220 so I'm going to put in a dash like so. 00:59.220 --> 01:01.020 Then, for every entry inside this ray, 01:01.020 --> 01:04.170 we're going to have a name and a value property. 01:04.170 --> 01:06.307 And, I bet you can guess what these are going to do. 01:06.307 --> 01:08.970 "Name" is going to be the name of the environment variable, 01:08.970 --> 01:12.090 and then "Value" is going to be the value for it. 01:12.090 --> 01:14.520 So, for our first named environment variable 01:14.520 --> 01:16.710 that we're going to pass into the worker, 01:16.710 --> 01:19.920 we'll pass in our Redis host. 01:19.920 --> 01:22.470 And again, this is going to be some type of reference 01:22.470 --> 01:24.930 telling our multi-worker container 01:24.930 --> 01:28.200 how it can reach out and connect to Redis. 01:28.200 --> 01:30.180 So, what we want to put in here, 01:30.180 --> 01:34.303 is the name of the cluster IP service 01:34.303 --> 01:36.450 that the worker needs to connect to 01:36.450 --> 01:37.800 to get at the Redis pod. 01:37.800 --> 01:39.690 And again, in this case, it's going to be 01:39.690 --> 01:41.640 Redis Cluster IP Service. 01:41.640 --> 01:43.430 Because that's what we provided as the name 01:43.430 --> 01:45.720 of that cluster when we put it together, 01:45.720 --> 01:47.610 that cluster IP, when we put it together 01:47.610 --> 01:50.970 inside of our Redis Cluster IP Service file. 01:50.970 --> 01:52.710 So, this is the string right here. 01:52.710 --> 01:54.033 That's what we care about. 01:54.930 --> 01:56.703 So, for the value, I will put in 01:56.703 --> 01:59.345 "Redis Cluster IP Service." 01:59.345 --> 02:01.678 -: (typing) 02:02.670 --> 02:04.290 -: And then, next up, we're going to also 02:04.290 --> 02:07.413 designate the Redis port. 02:08.520 --> 02:12.120 The port value here is going to be 6379, 02:12.120 --> 02:14.820 that is the default value for the 02:14.820 --> 02:17.160 Redis connection port. It's also what we wired up 02:17.160 --> 02:19.443 inside of our Redis Cluster IP. 02:20.490 --> 02:22.230 Service as both the opening port 02:22.230 --> 02:24.030 and the target port in there as well. 02:24.030 --> 02:25.230 So, this again, is going to be 02:25.230 --> 02:26.970 a hard-coded value, we're just going to 02:26.970 --> 02:30.633 throw it directly in here as 6379, like so. 02:32.430 --> 02:34.650 Okay, so that's it for the worker deployment. 02:34.650 --> 02:36.810 It's all the environment configuration we need. 02:36.810 --> 02:38.820 So, I'm going to close that file. 02:38.820 --> 02:43.170 And we're going to also open up our, where is it? 02:43.170 --> 02:45.690 The server deployment, right there, as well. 02:45.690 --> 02:47.430 So, in the server deployment, we're going to add in 02:47.430 --> 02:50.640 a set of environment variables to the server. 02:50.640 --> 02:53.490 So, I'm going to find the server container configuration. 02:54.330 --> 02:55.170 And, inside of here, 02:55.170 --> 02:58.170 we're going to do our .env block as well. 02:58.170 --> 03:00.840 Now, this one is going to have significantly greater 03:00.840 --> 03:02.340 number of environment variables. 03:02.340 --> 03:05.460 So, we're going to do a little bit of typing here. 03:05.460 --> 03:07.373 Let's see. We'll start off first 03:07.373 --> 03:10.270 with a name of "Redis Host". 03:10.270 --> 03:12.060 -: (typing) 03:12.060 --> 03:13.830 -: The value, again, is going to be the name 03:13.830 --> 03:16.830 of our Redis Cluster IP service, which was 03:16.830 --> 03:20.103 Redis Cluster IP Service. 03:21.900 --> 03:24.180 We'll do another array entry, so notice how I put 03:24.180 --> 03:26.040 another dash right here. 03:26.040 --> 03:28.383 This is going to be our Redis port. 03:29.670 --> 03:32.643 We'll have a value of 6379 over here as well. 03:34.710 --> 03:38.070 Next up, we'll do our PGUSER. 03:38.070 --> 03:39.210 So, this is going to be our 03:39.210 --> 03:41.060 default username for Postgres. 03:41.060 --> 03:44.040 And, we just use the default of Postgres, 03:44.040 --> 03:46.470 which is technically not good form, 03:46.470 --> 03:48.450 not the best way to make use of Postgres here, 03:48.450 --> 03:50.733 but totally fine for our purposes. 03:52.620 --> 03:54.423 Next up, we'll do our PGHOST. 03:56.353 --> 03:58.680 So the PGHOST is the connection string, 03:58.680 --> 04:00.360 we're essentially telling multi-server 04:00.360 --> 04:03.300 how to reach out to our Postgres instance. 04:03.300 --> 04:06.060 And so very similar to what we just did with Redis, 04:06.060 --> 04:09.390 we're gonna do the same thing with Postgres as well. 04:09.390 --> 04:10.770 We're going to provide the name 04:10.770 --> 04:13.020 of the Cluster IP service that is managing 04:13.020 --> 04:15.480 access to the Postgres pod. 04:15.480 --> 04:19.620 So, I'm going to open up the Postgres Cluster IP service 04:19.620 --> 04:22.500 config file right here, I'll find the name. 04:22.500 --> 04:24.090 And that's going to be the host name 04:24.090 --> 04:25.920 that we want to attempt to connect to 04:25.920 --> 04:27.783 to get access to that database. 04:29.070 --> 04:31.290 So, for my PGHOSTs, I'm going to put in 04:31.290 --> 04:33.933 Postgres Cluster IP service, like so. 04:37.440 --> 04:39.630 All right, so what do we have next? 04:39.630 --> 04:40.653 We have our PGPORT. 04:41.910 --> 04:43.550 The value for that, we are using the default 04:43.550 --> 04:46.590 of 5432, no changes there. 04:46.590 --> 04:49.860 Remember, we also set up our Postgres Cluster IP service 04:49.860 --> 04:51.813 to make that port available. 04:53.430 --> 04:55.020 And I think probably the last one, 04:55.020 --> 04:56.610 actually no I think we got two more here. 04:56.610 --> 04:57.990 What do we have? 04:57.990 --> 04:59.310 I just want to double check the diagram 04:59.310 --> 05:00.930 and make sure I'm not missing any in here. 05:00.930 --> 05:04.350 So, we got the port, I think it's the database, right? 05:04.350 --> 05:06.933 Yeah. All right, so we're gonna do our PGDATABASE. 05:08.490 --> 05:10.920 And again, we're using the default Postgres 05:10.920 --> 05:13.050 database of Postgres. 05:13.050 --> 05:15.390 Again, very much like the PGUSER, 05:15.390 --> 05:18.630 using the default database, not quite the best way 05:18.630 --> 05:20.640 of doing things, but for our purposes, 05:20.640 --> 05:22.500 it is good enough. 05:22.500 --> 05:24.570 All right, so I think that's it in terms of 05:24.570 --> 05:27.150 the initial set of environment variables. 05:27.150 --> 05:28.950 So let's take a quick pause right here. 05:28.950 --> 05:30.210 When we come back to the next section, 05:30.210 --> 05:32.580 we're gonna talk a little bit more about the PGPASSWORD 05:32.580 --> 05:34.530 and we're going to make sure that when we put this 05:34.530 --> 05:36.570 into a config file, we are not writing out 05:36.570 --> 05:38.400 the password in plain text. 05:38.400 --> 05:39.480 We're gonna make sure that we store it 05:39.480 --> 05:41.580 in a much more secure fashion. 05:41.580 --> 05:43.170 So quick pause and we'll take care of that 05:43.170 --> 05:44.163 in the next video.
