# Example call:
# poetry run ansible-playbook create-db-import.yml --ask-vault-pass -e "cluster_name='maria' cluster_size='1' stage='dev' upload_file='dumps/import.sql' uploaded_file='import.sql' target_database=test01"

# How this stuff works:
# If `upload_file` is defined the upload role save the binary to `upload_directory` (default /tmp)
# If `uploaded_file` and `target_database` are defined the import role imports from file basename `uploaded_file` to `target_database`
# If both role conditions match the upload role trigger first.
