Creating a Build Script for Go

A bash script to generate build for all OS in Go.

The Script

Copy the following script and save it as build.sh. You may want to set the script executable after save it - chmod +x build.sh.

#!/bin/bash

# Set the package name and version
if [ ! "$PACKAGE_NAME" ]; then
    echo -ne "\nMissing Package Name.\n"
    exit 1
fi

if [ ! "$PACKAGE_VERSION" ]; then
    echo -ne "\nMissing Package Version.\n"
    exit 1
fi

# Define the target operating systems and architectures with file extensions
TARGETS=(
  "linux/amd64:tar.gz"
  "linux/arm64:tar.gz"
  "darwin/amd64:tar.gz"
  "windows/amd64:zip"
)

# Set the output directory
OUTPUT_DIR="installers"

# Create the output directory if it doesn't exist
mkdir -p "$OUTPUT_DIR"

# Build for each target
for target in "${TARGETS[@]}"; do
  # Split the target into GOOS and GOARCH with file extension
  goos_arch="${target%:*}"
  file_extension="${target#*:}"
  IFS='/' read -r goos goarch <<< "$goos_arch"

  # Set the environment variables
  export GOOS="$goos"
  export GOARCH="$goarch"

  # Build the package
  echo "Building for $GOOS/$GOARCH..."
  file_name="${PACKAGE_NAME}-${PACKAGE_VERSION}-${GOOS}-${GOARCH}"
  output_file="$OUTPUT_DIR/$file_name"

  if [ $GOOS = "windows" ]; then
        output_zip="${output_file}"
        output_file+='.exe'
        GOOS=$GOOS GOARCH=$GOARCH go build -o "${output_file}"
        zip -m "${output_zip}.zip" "${output_file}"
    else
        GOOS=$GOOS GOARCH=$GOARCH go build -o "${output_file}"
        tar -czvf "${output_file}.tar.gz" "${output_file}"
    fi

    rm "${output_file}"
done

Usage

export PACKAGE_VERSION=1.0.0 && export PACKAGE_NAME=shipper && . ./build.sh

You should see all archives in installers/ directory.
