Access specific elements using with_items / with_subelememts

[Saranya N]

I have a variable file with dictionary under a role like below format :

Applformat:
- Appname : app-main
Parameters:
- x : a
Y : b
Z : c

- x : d
Y : e
- z : f
- Appname : app-relay
Parameters:
- x : g
Y : h
Z : I

- x : j
Y : k
Z : l

Etc many apps are there with different names.

I need to run a cli( my app command) that will make few apps as child n parent.

My command will be something like below.

Command : Kif run -parentappp {{ item.Appname }} -childapp {{ item.Appname }}
With_items :
- "{{ Appname }}"

I need a logic in my play to state which app is parent and which is child and need assistance on this.

My first app is always the parent of second app.

So first command should take first app as parent and second app as child.

My second app is parent of the 3rd, 4th .. etc remaining apps.

So these two conditions should be satisfied during the loop.

Kindly assist

Something like this should work

- command: Kif run -parentappp {{ Applformat[item | int].Appname }}
-childapp {{ Applformat[item | int + 1].Appname }}
with_sequence: start=0 end={{ Applformat | length - 1 }} stride=2

Hi Kai ,

M getting below error and I wonder why :(

Can't parse arg end=u'3\xa0stride=2' as integer .

Also please help me understand this,

My first app is parent of second and
Second app is parent of Remaining apps i.e from 3rd app onwards .

So I think I'll need the above task twice with different sequence number to achieve the two conditions ?

Just split it on two task with different with_sequences

You have gotten some strange character in there, delete it and write it
again.

Yes, that would be the easiest.
