Accessing group variable in template file of role belonging to another group

Inventory file:

[1]
IP

[2]
IP

[1:vars]
foo=test

How can I access variable foo in role which will be executed on group [2]?

Solution

  • Firstly, you cannot name host groups with a single digit, so fix the inventory file:

    [group1]
IP1

[group2]
IP2

[group1:vars]
foo=test

    Then when running against group2, to access the variable defined for group1, use the following construct:

    - debug:
    var: hostvars[groups['group1'][0]]['foo']

    Generally, I would try to avoid such references though.
