Reworked Dockerfile for a more production oriented usage - Added .dockerignore to speed up build context and avoid rebuilding when unecessary - Specified Alpine and Go versions as build arguments - Specified Go target CPU architecture as build arguments to be able to build for ARM devices - Specified base images as build arguments to be able to build for ARM devices - Trimmed down size of final image using `-a -installsuffix cgo -ldflags="-s -w"` go build flags and by copying the statically built binary only to the final image - Added clear build and run instructions for the Docker container 5 years ago			`ARG BASE_IMAGE_BUILDER=golang`

Added Docker labels and Go commit, version and buildSource 5 years ago			`RUN CGO_ENABLED=0 GOOS=linux GOARCH=${GOARCH} GOARM=${GOARM} go build -a -installsuffix cgo -ldflags="-s -w \`
Git commit reference mechanism changed - Git commit is passed as a build argument as explained in README.md - `.git` directory is ignored by Docker for a quicker build and smaller context - the build arg VCS_REF is used both to tag the image and the Go program 5 years ago			`-X main.commit=${VCS_REF} \`
