Hi Abhijeet,
Great help again. Thanks. This is what I have now:
- name: Add the ucloud_vm created into in-memory of ansible hosts.
vars:
user_data: "{{ lookup('file', '/root/mltr_source_code/mini.ip') }}"
tasks:
- add_host:
name: '{{ user_data }}'
groups: ucloud_vm_group
...
- name: Configure newly added hosts
hosts: ucloud_vm_group
tasks:
shell: touch /root/hello.txt
I get this when I run the playbook:
ansible-playbook 2.8.0
config file = /root/mltr_source_code/ansible.cfg
configured module search path = [u'/root/.ansible/plugins/modules',
u'/usr/share/ansible/plugins/modules']
