00:00.690 --> 00:01.523
Narrator: In the last section

00:01.523 --> 00:03.300
we created a docker compose file

00:03.300 --> 00:06.870
to avoid having to run that really long docker run command.

00:06.870 --> 00:10.110
However, when we tried to test out that docker compose file,

00:10.110 --> 00:11.580
we ran into a little bit of an issue

00:11.580 --> 00:14.370
because our docker file is not called docker file

00:14.370 --> 00:16.170
which is the convention.

00:16.170 --> 00:17.340
So in order to fix this,

00:17.340 --> 00:19.830
we're gonna make a slight tweak to the build option

00:19.830 --> 00:21.810
inside of our compose file.

00:21.810 --> 00:23.370
Rather than saying, oh yeah I just look

00:23.370 --> 00:27.480
into the current working directory for that docker file,

00:27.480 --> 00:31.113
we're going to replace that dot with two additional options.

00:32.070 --> 00:35.460
So the first thing we're going to do, is add a context.

00:35.460 --> 00:38.130
This context option is essentially specifying

00:38.130 --> 00:40.620
where we want all the files and folders

00:40.620 --> 00:42.690
for this image to be pulled from.

00:42.690 --> 00:44.280
So in this case, we definitely want

00:44.280 --> 00:45.930
all the files and folders for our project

00:45.930 --> 00:48.750
to come from the same directory as docker compose

00:48.750 --> 00:51.330
or essentially the current working directory.

00:51.330 --> 00:54.750
So to indicate that, we'll add a simple dot.

00:54.750 --> 00:57.690
If we had nested our react project right here.

00:57.690 --> 01:00.060
If we had nested it inside of some folder

01:00.060 --> 01:01.890
then we would have specified that folder.

01:01.890 --> 01:03.330
So we could have said something like

01:03.330 --> 01:06.180
look into my react project folder

01:06.180 --> 01:08.580
inside this directory to find all the files

01:08.580 --> 01:09.843
for our project.

01:11.850 --> 01:13.800
We're going to pass in a second option as well.

01:13.800 --> 01:15.900
This one's gonna be a little bit more obvious

01:15.900 --> 01:17.760
we'll say docker file.

01:17.760 --> 01:19.380
So this is just gonna be the location

01:19.380 --> 01:21.240
of the docker file that's gonna be used

01:21.240 --> 01:25.170
to construct the image for this web service.

01:25.170 --> 01:28.893
So for this, we'll say docker file.dev, like so.

01:29.820 --> 01:30.750
And as you might guess,

01:30.750 --> 01:33.750
this is indicating look in the current working directory

01:33.750 --> 01:37.230
find a file with that name, use it to build the image.

01:37.230 --> 01:38.430
All right, so let's save this

01:38.430 --> 01:41.073
and then we'll try running docker compose up again.

01:43.050 --> 01:44.040
So back in my terminal,

01:44.040 --> 01:45.783
I'll do docker compose up,

01:47.310 --> 01:48.390
and there we go.

01:48.390 --> 01:49.940
Now it's successfully building.

01:51.540 --> 01:53.130
So we're going to take a minute or two

01:53.130 --> 01:54.750
to run the end view install.

01:54.750 --> 01:56.820
Let's take a quick pause right here and just let that go.

01:56.820 --> 01:58.020
And then in the next section,

01:58.020 --> 02:00.090
we'll be able to test everything out again.

02:00.090 --> 02:02.483
So quick break and I'll see you in just a minute.
