Ansible evaulate dynamic varaible name from vars

[Yordan Borisov]

I have vars where I put something like this:

vars/main.yml

hello_port: 80

world_port: 81

in my ansbile file I load the vars with 

  vars_files:

     - ./vars/main.yml

and after that I have task with iterate using with_items:

     - debug:

          msg: "{{ (item + '_port') }}"

       with_items: "{{ m_name }}"

But I've got as output 

hello_port

world_port

not the values. 

Is there a way to evaluate the dynamically created variables name - to get the value?

What does the variable m_name contain?

I think your task is missing the lookup, i.e. it puts out the names of
the variable, that you want to get the value of.

Try this as the msg-line:
msg: "{{ [ (item + '_port') ] }}"

Or maybe you need to use hostvars syntax...

- debug:
msg: "{{ vars[item + '_port'] }}"
with_items: "{{ m_name }}"
