How to put period between two variables

So this will print what I want:

  • debug:
    msg: “{{ groups.tag_Name_shibboleth_aws_dev1[0] }}”

But I’m using a with_items and need something like this:

  • { host: ‘tag_Name_shibboleth_aws_dev1’, othervar: ‘blah’ }

  • debug:
    msg: “{{ groups.item.host[0] }}”

Joining the two like so doesn’t work:

“{{ groups + ‘.’ + item.host }}”

How do I do this?

Thanks,

Kenton Brede

Use the actual join filter:

"{{ [ groups, '.', item.host | join] }}"

You are looking for the "bracket notation", as described here:
http://docs.ansible.com/ansible/playbooks_variables.html#what-makes-a-valid-variable-name

So, this should work in your example:
"{{ groups[item.host][0] }}"

Cheers,
