1
00:00:01,100 --> 00:00:06,666
It is time that we get started with the key player of our course, Docker.

2
00:00:08,100 --> 00:00:13,133
Docker is an open platform for developers and system admins

3
00:00:13,133 --> 00:00:17,666
to build, ship, and run containerized applications.

4
00:00:18,233 --> 00:00:21,566
In other words, it is a containerization platform.

5
00:00:22,566 --> 00:00:25,133
Is Docker the only platform of its kind?

6
00:00:25,766 --> 00:00:31,633
Well, no. Certainly there are others like Rocket, but Docker

7
00:00:31,633 --> 00:00:33,400
is definitely the dominant one.

8
00:00:34,100 --> 00:00:37,766
By the time this course is being created, Docker is tried

9
00:00:37,766 --> 00:00:42,466
and tested and it is the top choice of industry unanimously.

10
00:00:42,566 --> 00:00:46,833
It means if you want to sharpen your containerization skills,

11
00:00:46,966 --> 00:00:52,433
Docker is potentially the best choice for various reasons, such as,

12
00:00:53,466 --> 00:00:55,466
more industries are using it,

13
00:00:55,466 --> 00:00:58,833
so it can land you on more relevant jobs.

14
00:00:59,433 --> 00:01:03,233
It is open source and has huge community support.

15
00:01:03,800 --> 00:01:08,400
A lot of third party applications are available to support Docker.

16
00:01:09,133 --> 00:01:12,700
Although it is built for Linux, it can be used on

17
00:01:12,700 --> 00:01:14,333
Windows and macOS

18
00:01:14,333 --> 00:01:17,433
for those who just don't have any other choice.

19
00:01:17,633 --> 00:01:21,200
There are other aspects as well, but there is no point on

20
00:01:21,200 --> 00:01:23,466
flooding your heads with information

21
00:01:23,466 --> 00:01:25,766
which you might not be able to relate to.

22
00:01:26,433 --> 00:01:29,133
We will get into those later into this course.

23
00:01:29,900 --> 00:01:34,433
In the next lecture, we will install Docker on a Linux machine.
