是否可以通过docker golang:alpine image构建静态的sqlite Go应用程序?

I'm trying to build my app which contains go-sqlite3 by docker.

main.go

package main

import (
        "database/sql"

        _ "github.com/mattn/go-sqlite3"
)

func main() {
        sql.Open("sqlite3", "test.db")
}

Dockerfile

FROM golang:alpine
RUN apk add --no-cache git
RUN apk add --no-cache sqlite-libs sqlite-dev
RUN apk add --no-cache build-base
WORKDIR /go/src/app
COPY *.go ./
RUN go-wrapper download
RUN go-wrapper install

I use this command to copy the compiled program out to my host OS (Arch Linux).

docker build -t mygo .
docker run --rm -v $$PWD:/usr/src/app mygo /bin/cp /go/bin/app /usr/src/app

The problem is the compiled program is missing dynamic library

$  ldd app
   ...
   libc.musl-x86_64.so.1 => not found

What I expected is like

$  ldd app
not a dynamic executable

    refer to how to create a statically linked golang executable with go 1.5+

    Change the Dockerfile's go-wrapper install line into

    RUN go-wrapper install -ldflags "-linkmode external -extldflags -static"
