#
# * have Docker installed;
# * have your Linux user associated with the appropriate system
# group, e.g., 'docker';
# * place in your sudoers file (see: the `sudoers` and `visudo`
# man pages) the line:
# ```
# <your Linux user name> ALL = NOPASSWD: /usr/bin/docker
# ```
# (where `<your Linux user name>` is your Linux user name --
# who would have thought?);
#
# 2) run this script with the `--own-db` command-line option.
