What version of Go are you using (go version)?

> docker run --rm golang:1.10 go version
go version go1.10 linux/amd64

Does this issue reproduce with the latest release?

yes

What operating system and processor architecture are you using (go env)?

> docker run --rm golang:1.10 go env

What did you do?

docker build .

Here is the Dockerfile:

FROM golang:1.10 AS builder

# Download and install vgo
RUN go get golang.org/x/vgo

# Login to github
COPY netrc /root/.netrc

# Copy the code and compile
COPY . ./
RUN vgo vendor

What did you expect to see?

Locally, vgo vendor creates a vendor directory and imports the dependencies specified in the go.mod file.

What did you see instead?

The command '/bin/sh -c vgo vendor' returned a non-zero code: 1

Here are the reported errors:

Here is the go.mod file:

module "github.com/pierreprinetti/ldb/web"

require "github.com/lib/pq" v0.0.0-20180201184707-88edab080323

I have no idea whether this is a problem of the Docker image only, in which case I apologise for posting this issue here.

I have more or less the same problem with vgo vendor and it's problem in Docker and on Windows machine too...

It looks like you have GOPATH=. and you are copying the module into that same place. The go get has the effect of creating ./src/golang.org/x/vgo, and then the COPY creates ./go.mod, so that it looks like the GOPATH's downloaded source lives inside the module. That in turn makes it look like src/golang.org/x/vgo is part of the project you are working on, and vgo gets very confused by its own (unsupported) use of vendoring.

Even if you did rm -rf src/golang.org/x/vgo after the go get, you will probably run into other problems with GOPATH and the module root being the same place. You should move one or the other instead.

I will repurpose this bug for detecting when there's a $GOPATH/go.mod and diagnosing that better.
