00:00:07,020 --> 00:00:08,810
- Welcome to lesson six.

2
00:00:08,810 --> 00:00:10,760
In this lesson, you'll learn
about the different ways

3
00:00:10,760 --> 00:00:12,640
that Ansible can be configured

4
00:00:12,640 --> 00:00:15,360
for conditional task execution.

5
00:00:15,360 --> 00:00:18,620
We'll start with an overview
of the different conditionals

6
00:00:18,620 --> 00:00:21,210
and next we'll start
exploring them one by one,

7
00:00:21,210 --> 00:00:23,280
starting with the Handlers.

8
00:00:23,280 --> 00:00:24,980
After Handlers, which only run

9
00:00:24,980 --> 00:00:26,810
if a task has changed something,

10
00:00:26,810 --> 00:00:29,180
you'll learn about the
powerful when statement,

11
00:00:29,180 --> 00:00:30,650
which allows you to run tasks

12
00:00:30,650 --> 00:00:32,543
if specific conditions are true.

13
00:00:34,040 --> 00:00:35,630
Next you'll learn how to use register

14
00:00:35,630 --> 00:00:37,980
in combination with when statements,

15
00:00:37,980 --> 00:00:40,380
after which you will learn
about blocks and loops.

16
00:00:40,380 --> 00:00:43,100
And in the last video,
before the end of lesson lab,

17
00:00:43,100 --> 00:00:45,070
you will learn how to use the fail module

18
00:00:45,070 --> 00:00:46,763
to deal with failure efficiently.
