Hi Ansible Guru's
I am using the CSV file as below for nfs volume migration as we have 1000
servers with 100 volumes. Hence, i would like to make to host inventory
using add_host file instead using inventory file. However, the loop is
failing when i use add_host module. Hence, i tried using json_query as
suggested by vladimar, and it is working for debug output but same is not
working for mount module as i would like to update /etc/fstab and mount the
volumes using this playbook. would you suggest the logic?
Playbook and CSV details:
=========================
# cat mounts.csv
host,remote_path,mnt_path,python
host1,nfsflr01:/volahcstg_www_masup_stg_data_01,/myasup/stg/data,/usr/bin/python2.6
host2,nfsflr01:/volahcstg_www_masup_stg_data_01,/myasup/stg/data,/usr/bin/python2.6
# cat mounts.yml
