How to configure start.sh as the Execution Script
Learn how to define start.sh so it automatically runs actions during the deploy process.
# start.sh
# Checks if the .env file exists in the Docker root directory
if [ -f "/.env" ]; then
echo "Copying .env from the root directory to the current directory ./"
cp /.env ./ # Copies the .env file to the current directory
else
echo "Warning: .env file not found in the Docker root directory."
fi
# Runs the Java application
java -jar standalone.jar -Xmx1024M -Xms256M
6. Done!
