​
Setup

Before diving into the deployment process, let’s set up some initial configurations:

DOMAIN=example.com
PROJECT_REPO="your_github_repo_name"
AMOUNT_KEEP_RELEASES=5

RELEASE_NAME=$(date +%s--%Y_%m_%d--%H_%M_%S)
RELEASES_DIRECTORY=~/$DOMAIN/releases
DEPLOYMENT_DIRECTORY=$RELEASES_DIRECTORY/$RELEASE_NAME

These variables define crucial aspects such as the domain name, project repository, and the number of releases to keep.

​
Cloning Repository and Setup

The script starts by creating a unique release directory and clones the project repository into it:

cd /home/forge/$DOMAIN

mkdir -p "$RELEASES_DIRECTORY" && cd "$RELEASES_DIRECTORY"

git clone "$PROJECT_REPO" "$RELEASE_NAME"
cd "$RELEASE_NAME"
git checkout "$FORGE_SITE_BRANCH"
git fetch origin "$FORGE_SITE_BRANCH"
git reset --hard FETCH_HEAD

​
Environment Setup

Next, the script copies the .env file from the project directory:

printf '\nℹ️ Copy ./.env file\n'
ENV_FILE=~/"$DOMAIN"/.env
if [ -f "$ENV_FILE" ]; then
  cp $ENV_FILE ./.env
else
  printf '\nError: .env file is missing at %s.' "$ENV_FILE" && exit 1
fi

​
Running Laravel Commands

$FORGE_COMPOSER install --no-dev --no-interaction --prefer-dist --optimize-autoloader

( flock -w 10 9 || exit 1
    echo 'Restarting FPM...'; sudo -S service $FORGE_PHP_FPM reload ) 9>/tmp/fpmlock

if [ -f artisan ]; then
    $FORGE_PHP artisan migrate --force
fi

​
Dependency Installation and Build

The script installs NPM dependencies and generates necessary files:

printf '\nℹ️ Installing NPM dependencies based on \"./package-lock.json\"\n'
npm install
printf '\nℹ️ Generating JS App files\n'
npm run build

​
Linking Deployment Directory

The script links the deployment directory to the current directory:

printf '\nℹ️ !!! Link Deployment Directory !!!\n'
echo "$RELEASE_NAME" >> $RELEASES_DIRECTORY/.successes
if [ -d ~/$DOMAIN/current ] && [ ! -L ~/$DOMAIN/current ]; then
  rm -rf ~/$DOMAIN/current
fi
ln -s -n -f -T "$DEPLOYMENT_DIRECTORY" ~/$DOMAIN/current

​
Clean Up

Lastly, the script performs clean-up tasks:

printf '\nℹ️ Delete failed releases:\n'
# Code for deleting failed releases

printf '\nℹ️ Delete old successful releases:\n'
# Code for deleting old successful releases

printf '\nℹ️ Status - stored releases:\n'
# Code for displaying stored releases

printf '\n✅ Deployment DONE: %s\n' "$DEPLOYMENT_DIRECTORY"
