Re: [ansible-project] How to configure playbook serial value by group var from inventory file?

[Deepesh Jakkal]

So Brain, how do we provide a serial value then? I also want to externalize 
it so that our operator can configure it. 
Currently the way it supports is using extra variables --extra-vars.

Thanks and Regards,
Deepesh

Thanks for the explaination.
Now I know the reason why I cannot set the value from inventory file.

And also thanks for branko to point out the inconsistence of variable 
names, I didn't notice that. :p

This is because serial is a play level keyword and must be the same
for ALL hosts in play, so inventory data cannot be used to set it.


You cannot set 'batches' of hosts for all play if the batch size keeps
changing per host.

Ansible is complaining that you are referencing a variable
"batch_deploy", and that it is not defined anywhere.

Here, the variable is called "deploy_batch".

Here, the variable is called "batch_deploy". E.g. not the same as in
the inventory file (swapped batch/deploy in the name).
