With the following Rockerfile,
FROM golang:1.7.4
RUN mkdir -p $GOPATH/src/github.com/digitalocean/bind_exporter && \
cd $GOPATH/src/github.com/digitalocean/bind_exporter && \
git clone https://github.com/digitalocean/bind_exporter.git . && \
go get && \
go build -v && \
ls -l /go/bin
EXPORT /go/bin/ /app
#####################################################################
FROM busybox
IMPORT /app
CMD ["/app/bind_exporter"]
TAG bind_exporter:{{ .Version }}
Build looks reasonable:
$ rocker build -var Version=v1

But when I run, I get the following error:

It seems that there's an issue exporting the go binary (bind_exporter) from the build image to the distribution image. I think I'm using IMPORT/EXPORT correctly, but I'm fairly new to Rockerfile, so it could totally be that, too. Help?

Nope. Problem was that go wasn't linking statically. Sigh.
