Wordpress using Bitnami docker containers - restore from existing wordpress site

.env

#  USAGE INSTRUCTIONS
#  1. Download this .env file, docker-compose.yml file, and put it in a separate folder.  
#
#  2. In above folder with: 'mkdir -p wpsite/mariadb wpsite/wordpress wpsite/dbinit' and 'chown 1001:1001 wpsite/mariadb'
#
#  3. Upload existing-site-dump.sql file to wpsite/dbinit and your existing wordpress (.htaccess, wp-config.php, and 
#     wp-contents folder) to wpsite/wordpress
#
#  4. Update the passwords in .env file. Backup 'cp wpsite/wordpress/wp-config.php wpsite/wordpress/wp-config-bak.php'
#   a. because setting WORDPRESS_SKIP_BOOTSTRAP=yes prevent fresh installation of wordpress, we must edit wp-config.php;
#      therefore, update wp-config.php with new database configuration - see docker-compose wordpress environments
#
#   b. As this is using bitnami, you may have to add to wp-config.php the setting "define( 'FS_METHOD', 'direct' );" in order
#      for Wordpress to perform core update from the UI.
#
#   c. Also fix permission with 'chown -R 1001:1001 wpsite/wordpress' before going to step 6.
#      Optionally, also perform below commands to fix Wordpress file permissions:
#        find wpsite/wordpress -type d -exec chmod 775 {} \;
#        find wpsite/wordpress -type f -exec chmod 664 {} \;
#        chmod 640 wpsite/wordpress/wp-config.php
#
#  5. Run the containers with -> docker-compose up -d
#
#  6. Done!
#
#  7. Now, put it behind CDN like cloudflare for performance.
