Hi,
Using a ‘shell’ task I’m obtaining a list of subnet id’s from Amazon, these subnet id’s I want to pass in to the ec2_elb_lb task.
However this task accepts a list for Subnets only, so is there a way to dynamically construct a list out of the id’s that I obtained?
Thanks,
Nico
Hi,
Instead of using shell, you could use a lookup plugin that will query the ids by name for you.
So when creating the subnets, give them a name and also store them in a list, e.g.
mysubnets:
You can then define your ELB like this:
ec2_elb_lb:
…
subnets: “{{ lookup(‘aws_subnet_ids_from_names’, (region, mysubnets)) }}”
Where region is a variable containing a region name, i.e. ‘eu-west-1’.
This will return a list of the subnet ids that the ec2_elb_lb module expects.
To use this, just copy the lookup plugin from here into a directory called lookup_plugins in the root of your project.
