[ansible-project] Working with variables

[Alexander Popov]

I not found answers in documentation, sorry if its lame, it's my first
day with ansible

i'm creating vpc:

ec2_vpc:

state: present

cidr_block: 172.30.0.0/16

subnets:

- cidr: 172.30.3.0/24

az: ..

resource_tags: { "tag" : "tag1" }

- cidr: 172.30.1.0/24

az: "{{ region }}a"

resource_tags: { ""tag" : "tag1" }

register: vpc


its assign value to vpc with array of subnets:

"subnets": [

{

"id": "subnet-zzzzzzz",

"resource_tags": {...

}

.. .

},

{

"id": "subnet-xxxxxxx",

"resource_tags": {...

}

...

}

},



for some other calls I need this subnets in different forms



for example ec2_elb_lb requires list of ids:


subnets:
- subnet-xxxxxxxx
- subnet-zzzzzzzz

How can i convert vpc.subnets array to array of ids? What if i need filter them by tag ?

Does it any analog for map of filter operations in ansible?
