Use distroless/go for the Docker image about ots HOT 2 CLOSED

This should definitely work. I've got this as a working concept.

FROM golang
WORKDIR /go
RUN go get gopkg.in/Luzifer/ots.v0
WORKDIR src/gopkg.in/Luzifer/ots.v0/
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o main .

FROM scratch  
COPY --from=0 /go/src/gopkg.in/Luzifer/ots.v0/main /main
ENTRYPOINT ["./main"]

from ots.

luzifer/ots     latest     0f52edc23446     3 hours ago       18.9MB
<none>          <none>     9a9b3b7febf2     8 seconds ago     12.7MB

Using scratch with only the binary inside would only mean a 6.2M reduction but a loss of any components possibly usable for later addition of additional storage providers requiring certificates or similar.

I had a look at the gcr.io/distroless/base image and the build process is totally intransparent: There is no Dockerfile but a bazel build loading stuff from some rulesets.

So for now the build in this repo will stay using alpine as its base.

If you want not to have the alpine base in the image you're using, I'm adding a Dockerfile.minimal to the repo you can use to docker build -f Dockerfile.minimal . an image without an alpine base.
