# Scans for docker projects in specified parent path and
# updates images, if applicable.
#
# The parent directory to search for docker-compose.yml
# files must be specified.  An optional service to update
# may be specified in the second argument. The default is
# to update services matching "*app".
#
# Only services which are currently running will be updated.
# The script will not automatically start stopped services.
#
# examples:
#   /ssdt/apply-updates.sh /data/preview
#   /ssdt/apply-updates.sh /data/preview usps
