RUN go-wrapper download   # "go get -d -v ./..."
RUN go-wrapper install    # "go install -v ./..."

#final stage
FROM alpine:latest
RUN apk --no-cache add ca-certificates
COPY --from=builder /go/bin/app /app
ENTRYPOINT ./app
LABEL Name=cloud-native-go Version=0.0.1
EXPOSE 3000

The error is :

Step 5/12 : RUN go-wrapper download   # "go get -d -v ./..."
 ---> Running in 70c2e00f332d
/bin/sh: go-wrapper: not found

i Build it with

go-wrapper has been deprecated and removed from the images using go version 10 and above. See here.

If you are fine using go v1.9 you can use the following image: golang:1.9.6-alpine3.7.

So your Dockerfile will be:

FROM golang:1.9.6-alpine3.7
WORKDIR /go/src/app
COPY . .
RUN apk add --no-cache git
RUN go-wrapper download   # "go get -d -v ./..."
RUN go-wrapper install    # "go install -v ./..."

#final stage
FROM alpine:latest
RUN apk --no-cache add ca-certificates
COPY --from=builder /go/bin/app /app
ENTRYPOINT ./app
LABEL Name=cloud-native-go Version=0.0.1
EXPOSE 3000
