Hi Sandeep,
You can write two plays to handle this situation. First play will add the
host and the second play will use the in-memory inventory generated by
first play to execute commands on newly added host.
So basically, your playbook will look like -
- name: Deploy VM and add in ucloud_vm_group
hosts: localhost
tasks:
- add_host:
name: '{{ user_data }}'
groups: ucloud_vm_group
...
- name: Configure newly added hosts
hosts: ucloud_vm_group
tasks:
- apt:
name: git
state: latest
I have removed details for the sake simplicity. Let me know if you have
any questions.
Thanks,
