Ensure lock issue on docker

[alex88]

I'm trying to fetch dependencies in a dockerfile to build the project

Locally on OSX it works fine, on docker with this dockerfile

FROM golang:1.8-alpine

# Package dependencies
RUN apk add --update --no-cache git libc-dev

# install dependency tool
RUN go get github.com/golang/dep && go install github.com/golang/dep/cmd/dep

# Copy project files
WORKDIR /go/src/github.com/prj/app
COPY . /go/src/github.com/prj/app

# Get dependencies
RUN dep ensure -v
# Compile code
RUN go build

RUN ["app"]

The ensure -v output is

Any idea?

Hello, welcome! Thanks for the issue report.

I wonder if this is just #323 again, despite it (oddly) only occurring within a container. I'm inclined to defer digging further in until we merge #325 (hopefully tonight); then, retest here.

@sdboyer oh sorry, haven't found that one, anyway, that branch works for me, so I'll close this issue as it's probable because of that issue. Thanks!
