Building the image from Docker

[grabekm90]

What is the preferred way to build the image from Docker?
I tried:

docker run --rm -v "$PWD":/go/src golang make -C /go/src build`

Then I got:

make: Entering directory '/go/src'
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -ldflags "-X main.Version=v1.0.0 -X main.Git=116fd50" -o build/rancher-letsencrypt-linux-amd64

        /go/src/github.com/janeczku/rancher-letsencrypt/rancher (from $GOPATH)
make: Leaving directory '/go/src'
make: *** [Makefile:29: build] Error 1

I do not use golang everyday...

Right, I found a build script:
https://github.com/TrueCarry/rancher-letsencrypt/blob/master/scripts/build.sh

Now we forked that repo and prepared a multistage Dockerfile:
