Dockerfile

# Dockerfile for Linux build automation.

# Run with 'DOCKER_BUILDKIT=1 docker build -o release .' from the repo root.

# Demonstrates developing PoE-Overlay on Linux and produces testable Linux
# builds. Each step will be cached independently, so subsequent builds will be
# faster. First build will take up to 10 minutes.
# IMPORTANT: Set DOCKER_BUILDKIT=1 in your environment variables or you will not
# get any build artifacts in your release folder.
