Build
docker build -t go_scratch .
Run
docker run --rm -i -t go_scratch
If everything went well we should see the following output
hello world
We can use the base golang image FROM golang:alpine AS builder to compile a standalone binary. Then in a new docker layer we can copy the built binary into a standalone layer.
FROM scratch
COPY --from=builder /go/src/hello/hi /go/src/hello/hi
This is great for security omiting all linux system utils and great for speedy deployments as we end up with a 2MB Go binary.
