Selecting subelements from variable

[Viktor Szathmáry]

Hi,

Let's say I have a variable structure like this:

vpc_subnets:

  - cidr: "172.22.1.0/24"

    az: "us-east-1a"

  - cidr: "172.22.2.0/24"

    az: "us-east-1b"

  - cidr: "172.22.3.0/24"

    az: "us-east-1c"

... and a task using it:

ec2_vpc:

  ...

  subnets: "{{ vpc_subnets }}"

  route_tables:

    - subnets:

        - "172.22.1.0/24"

        - "172.22.2.0/24"

        - "172.22.3.0/24"

      routes:

        - dest: 0.0.0.0/0

          gw: igw

I would like to avoid repeating the CIDRs in route_tables/subnets, and just select all the CIDRs from the vpc_subnets variable. Is there a nice way of doing this?

Thanks,

  Viktor

can you please try "

vpc_subnets | map(attribute='cidr')| list
