Test Docker BuildX

• A minimum example to build C code into docker image to run on multiple architects (amd64/aarch64).

Build and run on local docker env

./run build
./run up
./run ps

Build with GitHub Action

• See: .github/workflows/buildx.yml
• GitHub will run the action upon "git push", then it will push the docker image generated onto Docker Hub's registry.

Run on AMD64/ARM64 platform

docker run meetroger/hello
