How do you register variables from imported playbooks?

[ddrak...@gmail.com]

Hello,

I'm new to ansible and am trying to use import_playbook and register but it is not working. I have a playbook called vpc.yml:

- hosts: localhost

tasks:

- import_role:

name: vpc

vars:

aws_region: "{{aws_region}}"

register: public_subnet

within another playbook:

- import_playbook: vpc.yml

# register: public_subnet

- hosts: localhost

connection: local

gather_facts: False

name: set up EC2 instances

tasks:

- name: Provision a set of instances

ec2:

key_name: AnsibleTest

# group: test

instance_type: t2.micro

image: ami-900ae6e8

wait: true

exact_count: "{{ node_count }}"

count_tag:

Name: Test

instance_tags:

Name: Test

region: "{{aws_region}}"

vpc_subnet_id: public_subnet

register: ec2

If I run the above I get an error saying the subnet ID public_subnet is undefined, but if I try to change the import_playbook to user the register: public_subnet line commented above I get a syntax error.

I understand I could rather easily just use the VPC role in my top level playbook but I'm trying to learn. From what I understand this should be possible, or at least was possible before 2.4. What am I missing here?

Thanks!

You are getting an error because you are passing a string, the
'register' keyword is 'host specific' since the host in both plays is
'localhost' it is directly accessible, you should have:


vpc_subnet_id: "{{public_subnet}}"
