Geting vars from a different playbook to use as the "hosts" value

I am trying to run two playbooks at the same time, with one taking a var from the previous playbook.

My code is as follows

  • name: Provision AWS
    hosts: localhost
    gather_facts: no
    vars_files:
  • configs/aws.yml
    tasks:
  • debug: msg=‘tag_Name_{{ aws.ec2.Name }}’
    register: aws_host_target
  • hosts: {{ hostvars.localhost.aws_host_target.msg
    remote_user: ubuntu
    sudo: Trues
    tasks:
  • debug: var=hostvars.localhost.aws_host_target.msg

Yet everytime it hits the second playbook, the variable aws_host_target.msg is not readable specifically for the “hosts”

Any help would be great!

It’s not possible to use inventory variables in the “host” spec (“- hosts:”).

Also, don’t use debug with register, instead, if you need to set a variable:

“- hosts: {{ hostvars.localhost.aws_host_target.msg”

This is also an error because the trailing “}}” is missing.

You can pass in host spec parameters with “-e” on the command line.

Thanks! - that clarifies it for me.
