Ansible inventory aliases in molecule

[erplus]

Hi everyone!

Ansible supports feature such as inventory aliases - https://docs.ansible.com/ansible/latest/inventory_guide/intro_inventory.html#inventory-aliases
I use aliases to capable install more instances of service on single host.

The question is - how can i set and use aliases at molecule.yml for hosts in my tests? I use podman driver and i want test via molecule if my roles and playbook are able to install more than 1 instance of role/service.

Has anyone encounter this issue and know a solution?

Ok, i found a solution.

Example:

I have host (platform) with name: instance-master.
Then i put into:

• inventory/hosts.yml:

all:
  hosts:
    children:
      myhost-1: {}
      myhost-2: {}

• inventory/host_vars/myhost-1/vars.yml and inventory/host_vars/myhost-2/vars.yml :

ansible_host: instance-master
ansible_connection: podman

Above steps allow me to run molecule test on "two hosts" which are single container basically.
Of course there is need to link inventory files in a provisioner section.
