How to get ansible-pull with chroot connection to work?

Try to get ansible-pull -c chroot to work and I keep getting warnings and the playbooks are not run.

ansible-pull -vv -c chroot --accept-host-key -U git@xxx:ansible-roles/chroot-bootstrap.git

[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: provided hosts list is empty, only localhost is available. Note that
the implicit localhost does not match ‘all’

Current playbook is called local.yml

cat local.yml
