Docksal swap file command to increase swap size for Composer issues (beta)

swap.sh

#!/usr/bin/env bash

set -e  # Abort if anything fails

echo "Checking current swap space..."
fin exec free -h

# Increase swap memory
echo "Creating 512M swap file..."
fin exec sudo dd if=/dev/zero of=/swapfile bs=1M count=512

echo "Formatting swap file..."
fin exec sudo mkswap /swapfile
fin exec sudo chown root /swapfile
fin exec sudo chmod 0600 /swapfile

# echo "Adding swap to /etc/fstab..."
# fin exec sudo echo "/swap   swap  swap  defaults  0 0" >> /etc/fstab
# fin exec echo "/swap none swap sw 0 0" | sudo tee -a /etc/fstab
echo "Enabling swap..."
fin exec sudo swapon /swapfile -a

echo "Checking new swap space..."
fin exec free -h

Fstab doesn't look like it's available on these docker containers, so the command errors out.
