# Catlfish expects to find its configuration in
# /usr/local/etc/catlfish/catlfish.config so mounting
# /usr/local/etc/catlfish is recommended. This can be done using the
# `-v' flag to `docker run'.
#
# NOTE: The directory on the host system that's mounted at
# /var/local/db/catlfish in the container has to be writable by a host
# user with uid 147.
#
# Example, running a frontend node:
# $ docker run -v /etc/catlfish:/usr/local/etc/catlfish:ro catlfish
# frontend /usr/local/catlfish
#
# Example, running a merge node:
# $ docker run -v /etc/catlfish:/usr/local/etc/catlfish:ro catlfish
# merge /usr/local/catlfish /var/local/db/catlfish-merge
