Hi

Is there any simple dynamic inventory script that would read from a local file contain list of hostnames only?

Hi

No, but I thought that the format of the script needs to adhere to a JSON format.

a 'flat file' will work with the ini plugin, no need to create a script.

Hi

Oh, can you explain how you would do that in the Ansible code? I have just started using Ansible and I don’t know the language too well. Thanks.

There is no code, default Ansible inventory is just a file with one host on each line.
