I made a little bash script to automate a disc image creation.

It creates a temporary directory to store all needed files then export it in a new DMG file. Temporary directory is then deleted. You can automatically launch this script at the end of your build process.

#!/bin/bash
# Create .dmg file for macOS

# Adapt these variables to your needs
APP_VERS="1.0"
DMG_NAME="MyApp_v${APP_VERS}_macos"
OUTPUT_DMG_DIR="path_to_output_dmg_file"
APP_FILE="path_to_my_app/MyApp.app"
OTHER_FILES_TO_INCLUDE="path_to_other_files"


# The directory of the script
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

# The temp directory used, within $DIR
WORK_DIR=`mktemp -d "${DIR}/tmp"`

# Check if tmp dir was created
if [[ ! "${WORK_DIR}" || ! -d "${WORK_DIR}" ]]; then
    echo "Could not create temp dir"
    exit 1
fi

# Function to deletes the temp directory
function cleanup {
    rm -rf "${WORK_DIR}"
    #echo "Deleted temp working directory ${WORK_DIR}"
}

# Register the cleanup function to be called on the EXIT signal
trap cleanup EXIT

# Copy application on temp dir
cp -R "${APP_FILE}" "${WORK_DIR}"
# Copy other files without hidden files
rsync -a --exclude=".*" "${OTHER_FILES_TO_INCLUDE}" "${WORK_DIR}"

# Create .dmg
hdiutil create -volname "${DMG_NAME}" -srcfolder "${WORK_DIR}" -ov -format UDZO "${OUTPUT_DMG_DIR}/${DMG_NAME}.dmg"
