aerysinnovation/upx repository overview
UPX
Overview
A small image for usage in multi-stage Docker builds to compress binary files like Go or Rust. Based on the official busybox image and build via multi-stage build himself to make the image as small as possible ~1.7MB For more information on the great tool UPX check out their GitHub project!
Usage
CMD
To compress any file run following command
$ docker run --rm -w $PWD -v $PWD:$PWD gruebel/upx:latest --best --lzma -o [compressed file name] [file name]
Docker multi-stage build
For this example I used the official example of the Docker documentation for multi-stage builds
FROM golang:1.7.3 as builder
WORKDIR /go/src/github.com/alexellis/href-counter/
RUN go get -d -v golang.org/x/net/html
COPY app.go .
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o app .
# Before copying the Go binary directly to the final image,
# add them to the intermdediate upx image
FROM gruebel/upx:latest as upx
COPY --from=builder /go/src/github.com/alexellis/href-counter/app /app.org
# Compress the binary and copy it to final image
RUN upx --best --lzma -o /app /app.org
FROM alpine:latest
RUN apk --no-cache add ca-certificates
WORKDIR /root/
COPY --from=upx /app .
CMD ["./app"]
