1
00:00:07,230 --> 00:00:10,040
- In this video, you will
learn about the requirements

2
00:00:10,040 --> 00:00:12,560
for managing Docker
containers with Ansible.

3
00:00:13,590 --> 00:00:15,510
So what are these requirements?

4
00:00:15,510 --> 00:00:17,770
Well, in order to use Docker containers,

5
00:00:17,770 --> 00:00:21,680
dockerd, that's a daemon,
must be installed and started.

6
00:00:21,680 --> 00:00:23,807
Next, different specific
modules can be used

7
00:00:23,807 --> 00:00:26,300
to manage Docker containers.

8
00:00:26,300 --> 00:00:30,823
And you can use ansible-doc-l
grep docker for an overview.

9
00:00:31,930 --> 00:00:34,870
You should also notice that
you do not use docker modules

10
00:00:34,870 --> 00:00:37,520
for managing podman containers on Red Hat.

11
00:00:37,520 --> 00:00:40,370
I will show you in lesson 15.3

12
00:00:40,370 --> 00:00:42,863
how to manage podman
containers in Red Hat.

13
00:00:43,820 --> 00:00:45,870
But you should know that Red Hat,

14
00:00:45,870 --> 00:00:48,090
with the release of Red
Hat Enterprise Linux 8,

15
00:00:48,090 --> 00:00:49,880
has gone their own direction.

16
00:00:49,880 --> 00:00:51,890
And in that direction,

17
00:00:51,890 --> 00:00:56,850
there is just no place anymore for Docker.

18
00:00:56,850 --> 00:01:01,190
Podman is the default and
you shouldn't try to use

19
00:01:01,190 --> 00:01:04,930
RHEL8 and similar
distributions with Docker.

20
00:01:04,930 --> 00:01:05,820
That's not supported.

21
00:01:05,820 --> 00:01:07,240
It will break all the time.

22
00:01:07,240 --> 00:01:10,160
It's not working well,
so just don't do it.

23
00:01:10,160 --> 00:01:14,010
Now what is the high-level
overview of our tasks to be done?

24
00:01:14,010 --> 00:01:17,660
First, you need to add a
repository to install Docker.

25
00:01:17,660 --> 00:01:19,230
That is because Docker works best

26
00:01:19,230 --> 00:01:21,340
if you install from the Docker repository

27
00:01:21,340 --> 00:01:23,300
so that's what we are going to do.

28
00:01:23,300 --> 00:01:26,130
Then you need to install
and start the Docker daemon.

29
00:01:26,130 --> 00:01:29,520
Install the Python pip
module to support Docker

30
00:01:29,520 --> 00:01:31,780
and create container.

31
00:01:31,780 --> 00:01:35,460
And then you can generate a
list of learning containers.

32
00:01:35,460 --> 00:01:37,910
In the next video, you'll
see how we can do that.
