Hi,

I’ve inherited a legacy app that compiles Tohora from source at the start of the Dockerfile i.e.

```auto
# build tohora from source
FROM balenalib/raspberrypi3-golang as builder

RUN go get -d -v github.com/mozz100/tohora/...

WORKDIR /go/src/github.com/mozz100/tohora

RUN go build

```

When I try to use `balena push` to deploy the code to my test device I get the following error,

```auto
[main] Step 1/33 : FROM balenalib/raspberrypi3-golang as builder
[main] ---> 448bfdca5029
[main] Step 2/33 : RUN go get -d -v github.com/mozz100/tohora/...

[main]
[main] Removing intermediate container 164be2f108cf
[main] The command '/bin/sh -c go build' returned a non-zero code: 1

```

This code was deployed to other production devices and is still running on them fine. I can also run the Docker build locally too with no problems and everything just builds. Can anyone suggest why the code won’t deploy here? Should I be using a different method such as `git push` or something?

If anyone needs to know how to fix the issue, it appears to have come about with a change of versions in `go` in the base image. Later versions of go fetch packages into the `pkg/mod` folder rather than the `src` folder. To go back to the old behaviour simply add `ENV GO111MODULE=off` before the `RUN go get` command
