     desitnation: /var/www/mysite/

hooks:
  AfterInstall:
    - location: scripts/AfterInstall
      timeout: 300
      runas: root

scripts/AfterInstall:

Create a File AfterInstall

#!/bin/bash
if [ "$DEPLOYMENT_GROUP_NAME" == "development" ]
then
	cd /var/www/mysite/my_profile && \
    git clean -df && \
    git fetch && \
    git checkout development && \
    git reset --hard origin/development && \
    chmod +x build.sh && \
    ./build.sh

Optional:

elif [ "$DEPLOYMENT_GROUP_NAME" == "staging" ]
then
    cd /var/www/mysite/staging-site/ && \
    git clean -df && \
    git fetch && \
    git checkout staging && \
    git reset --hard origin/staging && \
    cd /var/www/mysite/staging-site/public/api-doc && \
    apidoc -i input/ -o output/ && \
    cd /var/www/mysite/staging-site && \
    chmod +x build.sh && \
    ./build.sh

fi

build.sh:

Create a file build.sh

#!/bin/bash
#Auto run after deploy source code
composer install && \
composer dumpautoload && \
sudo chmod -R 777 storage bootstrap/cache
php artisan migrate --force && \
php artisan cache:clear && \
php artisan config:clear && \
php artisan route:clear && \
php artisan view:clear

Before deploy in server for the first time run composer update locally remove vendor/ folder for gitingonre and upload it upload composer.lock Because in server there is not enough memory to run composer update, composer install will read all deopendency from composer.lock
