WEBVTT 00:00.870 --> 00:03.300 -: The running theme that we have seen with Docker Compose 00:03.300 --> 00:04.890 is that it makes it a lot easier 00:04.890 --> 00:07.800 to work with multiple containers at the same time. 00:07.800 --> 00:08.633 In this section, 00:08.633 --> 00:10.650 we're gonna take a look at two different commands 00:10.650 --> 00:12.930 that we had previously used with Docker CLI, 00:12.930 --> 00:14.430 and get a sense of how to run them 00:14.430 --> 00:16.530 with Docker Compose instead. 00:16.530 --> 00:18.360 So the two commands we're gonna look at, 00:18.360 --> 00:20.280 well just the first one for right now, 00:20.280 --> 00:22.320 we'll move on to the second one in just a moment. 00:22.320 --> 00:25.410 I want you to recall that in the past we executed a, 00:25.410 --> 00:29.760 or created a container by running docker run -d, 00:29.760 --> 00:32.910 and then the name of an image, like say Redis. 00:32.910 --> 00:34.530 This started up a new container, 00:34.530 --> 00:37.470 but it executed it in the background so we could continue 00:37.470 --> 00:41.190 running commands in this terminal window if we wanted to. 00:41.190 --> 00:42.840 We could then get a printout 00:42.840 --> 00:46.500 of all of our running containers with docker ps, 00:46.500 --> 00:48.600 so there's the container I just created. 00:48.600 --> 00:52.200 And I could then stop that container by copying the ID 00:52.200 --> 00:56.013 and executing docker stop and pasting the ID. 00:57.090 --> 00:58.260 Now you can kind of imagine 00:58.260 --> 01:00.120 that when we start using Docker Compose 01:00.120 --> 01:02.250 and we're working with multiple images 01:02.250 --> 01:04.710 or multiple containers at the same time, 01:04.710 --> 01:07.920 it would really be a pain to have to run docker stop 01:07.920 --> 01:11.400 with each different ID for each container we started. 01:11.400 --> 01:12.630 So with Docker Compose, 01:12.630 --> 01:14.880 we can automatically start up multiple containers 01:14.880 --> 01:16.440 in the background at the same time, 01:16.440 --> 01:18.540 and then close them all at the same time 01:18.540 --> 01:20.760 with one single command. 01:20.760 --> 01:22.740 So here's how we do it. 01:22.740 --> 01:25.260 To start up a group of containers in the background 01:25.260 --> 01:28.980 using that -d flag before, like we did with Docker CLI, 01:28.980 --> 01:33.450 we can run docker compose up and then -d on the very end. 01:33.450 --> 01:35.760 We can then stop all of our running containers 01:35.760 --> 01:37.800 with docker compose down. 01:37.800 --> 01:40.530 An easy way to remember down right here is that hey, 01:40.530 --> 01:43.833 docker compose up, the opposite of going up is going down. 01:44.730 --> 01:45.903 So let's try this out. 01:46.980 --> 01:48.870 Still inside of my visits directory, 01:48.870 --> 01:52.500 I'll run Docker compose up -d. 01:52.500 --> 01:53.460 That's gonna start up 01:53.460 --> 01:55.500 both of my containers in the background 01:55.500 --> 01:57.800 so I can continue running other commands here. 01:58.710 --> 02:00.870 I can do a docker ps, 02:00.870 --> 02:03.420 that'll show our two running containers. 02:03.420 --> 02:05.550 And then to stop both of them at the same time 02:05.550 --> 02:09.603 we can do a docker compose down like so. 02:11.070 --> 02:12.960 And when I run that, it's gonna stop 02:12.960 --> 02:16.260 and then remove the two containers we had created. 02:16.260 --> 02:20.370 So if I do another docker ps, nope, nothing's here anymore. 02:20.370 --> 02:21.780 All right, so that's pretty much it. 02:21.780 --> 02:24.570 Again, there's a lot of commands from the Docker CLI world 02:24.570 --> 02:26.700 that have kind of a one-to-one translation 02:26.700 --> 02:28.710 over to Docker Compose. 02:28.710 --> 02:30.240 So let's take a quick pause right here, 02:30.240 --> 02:32.370 and we'll continue looking at a couple of other commands 02:32.370 --> 02:33.370 in the next section.
