# This file was shamelessly copied from the Docker Registry Browser role.
#
# We use the `htpasswd` tool to generate the htpasswd file.
# There's an Ansible module that helps with that, but it requires passlib (a Python module) to be installed on the server.
# See: https://docs.ansible.com/ansible/2.3/htpasswd_module.html#requirements-on-host-that-executes-module
# We support various distros, with various versions of Python. Installing additional Python modules can be a hassle.
# As a workaround, we run `htpasswd` from an Apache container image.
