1
00:00:01,550 --> 00:00:04,120
Up to this point in the course,

2
00:00:04,120 --> 00:00:06,689
we learn a lot about images and containers,

3
00:00:06,689 --> 00:00:08,990
And we got a very solid foundation

4
00:00:08,990 --> 00:00:11,600
for diving deeper into Docker

5
00:00:11,600 --> 00:00:15,710
and deeper into working with these concepts.

6
00:00:15,710 --> 00:00:19,080
Now in this module, we are going to explore

7
00:00:19,080 --> 00:00:21,470
how we can manage our data

8
00:00:21,470 --> 00:00:23,950
inside of images and containers.

9
00:00:23,950 --> 00:00:26,060
This might sound strange at first,

10
00:00:26,060 --> 00:00:27,670
because up to this point,

11
00:00:27,670 --> 00:00:31,320
we already had data in images and containers, right?

12
00:00:31,320 --> 00:00:34,380
We already had our code in there for example.

13
00:00:34,380 --> 00:00:38,430
Well, turns out there are different kinds of data,

14
00:00:38,430 --> 00:00:39,810
and up to this point,

15
00:00:39,810 --> 00:00:42,680
we're only able to manage one kind of data

16
00:00:42,680 --> 00:00:44,600
in our images and containers,

17
00:00:44,600 --> 00:00:47,833
and we'll face problems with the average kinds.

18
00:00:48,710 --> 00:00:50,970
We'll then, throughout this module,

19
00:00:50,970 --> 00:00:54,110
dive into how images and containers

20
00:00:54,110 --> 00:00:57,020
can manage data in different ways

21
00:00:57,020 --> 00:01:00,590
and how you can connect to different folders

22
00:01:00,590 --> 00:01:03,140
and much more and we'll specifically dive

23
00:01:03,140 --> 00:01:05,220
into a concept called volumes,

24
00:01:05,220 --> 00:01:07,250
which is built into Docker.

25
00:01:07,250 --> 00:01:09,560
And towards the end of this module,

26
00:01:09,560 --> 00:01:13,840
we're also going to explore a kind of related concept.

27
00:01:13,840 --> 00:01:18,050
We're going to explore arguments and environment variables

28
00:01:18,050 --> 00:01:22,310
and see how we can use them in Docker images and containers

29
00:01:22,310 --> 00:01:25,233
and why we might wanna use those things.
