# Script to update all docker-compose based wordpress sites, plugins and themes
# Created by: Sam R.
# Created at: 2023-05-05
# Usage:
# - run the script from the directory, or parent directory, containing your docker-compose.yml files
# - the script will skip any directories that don't contain a docker-compose.yml or wordpress container
# - the script will update wordpress core, plugins and themes in each directory
#
# Example directory structure:
# /var/www/
# ├── docker-compose.yml ~ ingress proxy, etc
# ├── compose-wordpress-update.sh ~ this script
# ├── .env
# ├── site1.co.uk
# │   ├── docker-compose.yml ~ wordpress site
# │   ├── .env
# ├── site2.co.uk
# │   ├── docker-compose.yml ~ wordpress site
# │   ├── .env
# ├── site3.co.uk
# │   ├── docker-compose.yml ~ non-wordpress site
# │   ├── .env
