# Buildkit to simplify the whole process of upgrading Wordpress with official images
# 
# This version is designed for fpm, using a default.conf which references the wordpress service
#
#  STEPS:

#  Set COMPOSE_PROJECT_NAME in .env
#  docker compose down -v
#  Change wordpress version as required in Dockerfile.wordpress_fpm and .env (IMAGE_FIRST)
#  docker compose -f docker-compose.first.yml build 
#  docker compose -f docker-compose.first.yml up -d
#  docker compose -f docker-compose.first.yml down
#  docker compose up -d
#  at this point manually copy everything from wp-content-new to wp-content: cp -a wp-content-new/* wp-content/
#
#  MAKE SURE PERMISSIONS ARE CORRECT in wp-content
#  (if you need to) ./update-db
