And here is the inventory file you need to create:

hosts

[test]
test1.tld checkmk_folder_path="/test" 
test2.tld checkmk_folder_path="/foo" 
test3.tld checkmk_folder_path="/bar" 
test4.tld checkmk_folder_path="/" 
test5.tld checkmk_folder_path="/foo" 
test6.tld checkmk_folder_path="/bar" 
test7.tld checkmk_folder_path="/" 
test8.tld checkmk_folder_path="/test" 
test9.tld checkmk_folder_path="/bar" 
test10.tld checkmk_folder_path="/foo"

And the vars file:

./vars/config.yml
