This is a Proof of Concept for the ansible bug include/include_role: maximum recursion depth exceeded (direct link to the bug)
It simulates a useless set of role that are chained to each other
- role
r1prints a debug message, includes roler2usinginclude_role, prints another debug message and leave - role
r2prints a debug message, includes roler3usinginclude_role, prints another debug message and leave - role
r3prints a debug message, includes roler4usinginclude_role, prints another debug message and leave - ... and so on
- the last role (currently role
r41) only prints a debug message and leave

Everything works fast and as expected.
Create nested import_roles
This extra step is necessary, because some ansible bug sometimes trigger compilation or parsing error and avoid any real testing of 'max nested import_roles'
$ ansible-playbook -e max_nested_import_roles=10 import-create_roles.yml
[...]
Call the nested import_roles
$ ansible-playbook import-poc.yml
[...]
ERROR! A recursion loop was detected with the roles specified. Make sure child roles do not have dependencies on parent roles
The error appears to have been in '/home/user/ansible_POC_include_role_max_recursion_depth_issue_23609/import-poc.yml': line 8, column 15, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
- import_role:
name: 'import_r1'

After this ansible bug comment, update the test/poc suite. The
include_roleseems now fully functionnal and pretty fast, thanks to the dev' work ! -
The
import_rolestatement seems still hard to use
