# -----------------------------
# Builder stage
# -----------------------------
# Uses Maven with Eclipse Temurin Java 21 on Alpine.
# This stage builds the application jar only.
FROM maven:3.9.15-eclipse-temurin-21-alpine AS builder

# Copy the full project into the build container.

# Set project directory.
WORKDIR /usr/src/app/

# Build the project and create the application jar.
# -B = batch mode, useful for CI
# -ntp = no transfer progress, cleaner logs
# Tests and JaCoCo are skipped because this image only needs the built runtime jar.

# -----------------------------
# Final runtime stage
# -----------------------------
# Uses a smaller Alpine-based Eclipse Temurin Java 21 JRE image.
# This avoids the Ubuntu-based OS package vulnerabilities reported by Snyk.

# Fix the startup script for Alpine runtime:
# 1. Remove Windows CRLF line endings if present.
# 2. Replace #!/bin/bash with #!/bin/sh because Alpine does not include bash by default.
# 3. Make the script executable.
# 4. Validate that the jar and startup script exist during image build.
