Problem with "Skipping: No hosts matched" when using add_host and groups

[Alex White]

Hello,

I'm launching an AWS instance and setting that instances' new public IP address to a variable, and attempting to add that host to a group. Later in the same play, I use that group name in the topology.yml to remotely configure it.

I successfully get the IP address from the newly created instanced:

#Set the CoreA public IP to a var and use it to configure the remote host
- set_fact:
corea_public_ip: "{{ instance_public_ip.stdout }}"
- add_host:
name: "{{ corea_public_ip }}"
groups: corea_launched

Later in the same play, I want to use that new group (corea_launched) var to connect to it:

- name: Configure the Core Node A
hosts: corea_launched
become_user: sudo
become_method: sudo
roles:

- role: configure_coreA

Once it gets to that part of the play it skips over and says no hosts matched.

I know that the add_host is working:

TASK [provision_instances : add_host] **************************************************************************************************************************************************************************

task path: /roles/provision_instances/tasks/corea_lc.yml:86

creating host via 'add_host': hostname=34.XX.XX.XX

changed: [local] => {

    "add_host": {

        "groups": [

            "corea_launched"

        ], 

        "host_name": "34.XX.XX.XX", 

        "host_vars": {}

    }, 

    "changed": true

}

PLAY [Configure the Core Node A] **************************************************************************************************************************************************************************

skipping: no hosts matched

I've tried both with and without [corea_launched] group name in my hosts file.

Thanks in advance!
