I have a similar problem but the solution doesn't seem to apply.
I have multiple plays in a single playbook, but all the plays are on
localhost. A fact set in one play does not seem to be available in
other
plays, because the hostname is "localhost" for all of them! Is there
anyway
to distinguish between such plays?
It works, you probably just overlooked the variable.
$ ansible --version | head -n 1
ansible 2.6.3
test.yml
---
- hosts: localhost
gather_facts: no
tasks:
- set_fact:
local_var: "play 1"
- hosts: localhost
gather_facts: no
tasks:
- debug:
var: hostvars['localhost'].local_var
- set_fact:
local_var: "play 2"
- hosts: localhost
gather_facts: no
tasks:
- debug:
var: hostvars['localhost'].local_var
Output:
$ ansible-playbook test.yml

The only facts output by the final debug statement are those in the
current
play.
As you can see the variable is carried through to the next play.
But only the last one "stick" since the fist one is overwritten by the
second one.
Is there any way to reference the variables in the earlier plays? For
example, is there some way to provide an "alias" for a host in the
"hosts"
declaration?
You already create aliases in the inventory, the fist part is called
alias.
Alias here is myhost
myhost ansible_host=<any real ip or hostname>
To avoid the overwriting part you need unique variable names.
