# DRUSH WRAPPER
# This wrapper script enables Drush to be seamlessly run inside of our PHP
# Docker container, using the locally installed Drush.
# You can find out more about Drush wrapper scripts from their repo in the
# examples folder.

# This wrapper has been tested with the following Drush commands.
# drush @docker status
# drush @docker status | tee file.txt
#
# drush @docker sql-cli
# echo "show tables" | drush @docker sql-cli
# echo "show tables" | drush @docker sql-cli | tee file.txt

# Only running Drush on the docker container when it's being requested means
# that it is still possible to connect to remote services, because the Docker
# container doesn't have access to our ssh keys.
