# MCP Sessionize Server - Quarkus Native Multi-stage Build
# =============================================================================
# Builds a native executable using Mandrel (Red Hat's GraalVM distribution)
# and deploys on the smallest possible image (ubi9-quarkus-micro-image)
#
# Build:
# docker build -t ghcr.io/jeanlopezxyz/mcp-sessionize .
#
# Run:
# docker run -i --rm -p 8080:8080 -e SESSIONIZE_EVENT_ID=xxx ghcr.io/jeanlopezxyz/mcp-sessionize
#
# Image size: ~50-100MB (vs ~400MB with JVM)
# Startup time: ~50ms (vs ~2s with JVM)
