Laravel Forge zero downtime deployment script

laravel-forge-deploy.sh

# stop script on error signal
set -e

SITE="your-site-original-folder-name.com"
DEPL="/home/forge/deployments/${SITE}"

# create directory and any intermediate directories if don't exist
mkdir -p ${DEPL}

CUR="/home/forge/${SITE}"
NEW="${DEPL}/new"
BKP="${DEPL}/backup"

# remove old deployment folders
if [ -d ${NEW} ]; then
 rm -R ${NEW}
fi
if [ -d ${BKP} ]; then
 rm -R ${BKP}
fi

cp -R ${CUR} ${NEW}

cd ${NEW}

# REGULAR SCRIPT (git pull, whatever you do to build assets, reload php clean opcache...)
git pull origin develop
composer install --no-interaction --prefer-dist --optimize-autoloader --no-dev
echo "" | sudo -S service php7.1-fpm reload
# /REUGLAR SCRIPT

# Switch (downtime for microseconds)
mv ${CUR} ${BKP}
mv ${NEW} ${CUR}

I would make this one change on the $SITE variable

SITE=${FORGE_SITE_PATH#"/home/forge/"}

That way, it's fully dynamic and you could copy/paste to a testing/prod environment without changing much.
