# Database data captured inside of the container.
#
# Use existing upstream image, but override DB storage directory listed as
# a VOLUME (as Docker does not export volumes) with a different location.
# This requires altering entrypoint script (current entrypoint script does not
# support setting data directory as an environment variable) to support new
# location and overriding default CMD to include our custom data directory.
#

# Set the data directory to a different location that a mounted volume.

# Add customised entrypoint script.
COPY entrypoint.bash /lagoon/entrypoints/9999-mariadb-init.bash
