00:00.000 --> 00:03.970
So friends here is the validation challenge. The very first thing I would like

2
00:03.970 --> 00:04.800
you to do is to

3
00:04.800 --> 00:09.770
use DNF to download the rail system roles on your control mode. Once you've

4
00:09.770 --> 00:10.480
done that,

5
00:10.480 --> 00:15.520
write a playbook that uses a rail system role to deploy a post-gracio server on

6
00:15.520 --> 00:15.920
each of your

7
00:15.920 --> 00:20.520
managed devices. Make sure that the version of the post-gracio server is

8
00:20.520 --> 00:21.760
version 13.

9
00:21.760 --> 00:26.020
Then lastly, I wanted to create an additional task within the playbook called

10
00:26.020 --> 00:27.280
Validation Task

11
00:27.280 --> 00:31.840
and this task should simply print out the message "automation is fun". So give
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

11
00:27.280 --> 00:31.840
and this task should simply print out the message "automation is fun". So give

12
00:31.840 --> 00:32.000
it a

13
00:32.000 --> 00:34.920
thank but up your terminal and I will see you in the very next video where we

14
00:34.920 --> 00:37.440
'll discuss the solution.
