Synopsis

  • Use the inventory plugin ansible.builtin.constructed after the two iocage inventory files.

  • The iocage plugin gets the jails(hosts):

    • test_01:03 from the host iocage_01

    • test_11:13 from the host iocage_02

    and creates inventory groups test_01 and test_02

  • The constructed plugin creates inventory group test including all hosts starting ‘test’
