Hi Deepak,
I would suggest using the vault mechanism to securely store the encryption
secret if possible, so the process can be fully automated. That will also
allow safe storage of any other confidential information needed by the
playbook. As for handing of the log files, copy normally only pushes from
the controller to the remote and therefore you likely want to use something
else. If those logs are small then using "ansible.builtin.slurp" to get the
content, filtering that with the "vault" filter, and then saving that
locally using a local_action delegated copy task may be an option. A more
flexible method would use "ansible.builtin.fetch" to copy to a local
ramdisk, encrypt locally via a "local_action" task using native cli tools
(such as gpg or the command-line version of Ansible vault), and then save
someplace appropriate via a "local_action" task using
"ansible.builtin.copy".
I hope you find this helpful.
