You must either add a leading zero so that Ansible's YAML parser knows it is an octal number (like C(0644) or C(01777)) or quote it (like C('644') or C('1777')) so Ansible receives a string and can do its own conversion from string into number. Giving Ansible a number without following one of these rules will end up with a decimal number which will have unexpected results. As of Ansible 1.8, the mode may be specified as a symbolic mode (for example, C(u+rwx) or C(u=rw,g=r,o=r)). As of Ansible 2.6, the mode may also be the special string C(preserve). When set to C(preserve) the file will be given the same permissions as the source file.
