# Development Dockerfile for Multiway Gateway (Control Plane + Data Plane)

# This Dockerfile uses a lower optimization profile for faster builds.
# Use this for development and testing; use the main Dockerfile for production.

#   docker build -f Dockerfile.dev --target controlplane -t multiway:dev .
#   docker build -f Dockerfile.dev --target dataplane -t multiway-dataplane:dev .
