Using Xdebug in Docker

Getting setup and running with Xdebug in a docker container these days is now fairly simple and is composed of two main steps:

1. Ensure you've got XDebug installed and enabled in your PHP docker image, for example:

   # Installing Xdebug with PHP 7.3 images:
   RUN pecl install xdebug \
     && docker-php-ext-enable xdebug

# best practice: linux
nano ~/.pgpass

chmod 0600 ~/.pgpass

# best practice: windows
edit %APPDATA%\postgresql\pgpass.conf

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

# This is just a cheat sheet:

# On production
sudo -u postgres pg_dump database | gzip -9 > database.sql.gz

# On local
scp -C production:~/database.sql.gz
dropdb database && createdb database
gunzip < database.sql.gz | psql database

# check if there is a file named maintenance.html
# so when you want to disable maintenance mode just remname "mv maintenance.html maintenance.html.disabled"
RewriteCond %{DOCUMENT_ROOT}/maintenance.html -f
RewriteCond %{SCRIPT_FILENAME} !maintenance.html
RewriteRule ^.*$ /maintenance.html [R=503,L]
