# 1. Clone and setup
git clone https://github.com/vibheksoni/stock-assist.git
cd stock-assist
2. Create environment file
cp .env.example .env
3. Edit environment variables (see Environment Configuration section)
nano .env
4. Start all services
docker-compose up -d
5. Check service status
docker-compose ps
6. View logs
docker-compose logs -f
7. Access application
http://localhost (if running locally)
https://yourdomain.com (if deployed)
8. Stop services
docker-compose down
9. Reset everything (careful - deletes data!)
docker-compose down -v
docker system prune -a

Docker Services:

• MySQL 8.0: Primary database
• Redis Alpine: Caching and session storage
• App Container: Flask application (optional)

Before running the application, you MUST update these configuration files:

1. Docker Compose Configuration

# Update MySQL password (Line 22)
MYSQLROOTPASSWORD: "yoursecurepassword_here"
Example secure password generation:
python -c "import secrets; print(secrets.token_urlsafe(32))"

2. Database Setup Configuration

-- Update default admin credentials
-- Change default passwords and email addresses
-- Update any domain-specific configurations

3. Environment Variables

# Update these critical variables:
SERVER_NAME=yourdomain.com
OXAPAYRETURNURL=https://yourdomain.com/payments/success
OXAPAYCALLBACKURL=https://yourdomain.com/payments/callback
MYSQLROOTPASSWORD=yoursecurepassword_here

4. Automated Domain & Contact Update (Recommended)

# Basic domain update
python update_domains.py --domain your-actual-domain.com
Complete update with social media handles
python update_domains.py \
  --domain your-actual-domain.com \
  --github your-github-username \
  --discord your-discord-username \
  --email admin@your-actual-domain.com
For production deployment (replaces yourdomain.com)
python update_domains.py \
  --domain your-actual-domain.com \
  --github your-github-username \
  --discord your-discord-username \
  --email admin@your-actual-domain.com \
  --replace-original
Preview changes without making them
python update_domains.py --domain your-domain.com --dry-run

4b. Manual Domain Replacement (Alternative)

# Replace placeholder domains
find . -type f -name "*.py" -exec sed -i 's/yourdomain\.com/your-actual-domain.com/g' {} +
find . -type f -name "*.js" -exec sed -i 's/yourdomain\.com/your-actual-domain.com/g' {} +
find . -type f -name "*.html" -exec sed -i 's/yourdomain\.com/your-actual-domain.com/g' {} +
If replacing the original domain (for production deployment)
find . -type f -name "*.py" -exec sed -i 's/yourdomain\.com/your-actual-domain.com/g' {} +

5. Social Media & Contact Information

• Discord: Change 1codec to your Discord username
• GitHub: Change @vibheksoni to your GitHub username
• Email: Update any email addresses in configuration files
• Social Links: Update any social media references

6. Security Considerations

# Generate secure passwords
python -c "import secrets; print('MySQL Password:', secrets.token_urlsafe(32))"
python -c "import secrets; print('Flask Secret:', secrets.token_hex(32))"
Update these in your .env file:
FLASKSECRETKEY=generatedflasksecret_here
MYSQLROOTPASSWORD=generatedmysqlpassword_here
