Dependency path issues setting up Dep with Docker

Hi guys, I'm stuck on this Dep issue that I can't fix, it's probably something stupid that I'm missing, maybe you can give me some hints on it.

I've got my Go project running in a Docker container. I install and manage my dependencies with Dep. So far so good until I'm trying to split my code in a different package. The sub-packages won't find my vendor dependencies installed with Dep anymore.

When I move all my files back to one folder and rename everything back to "main" package it starts working.

This is the error I get:

root@c348fbca321e:/go# go run src/my-lib/main.go
src/my-lib/mySubLib/db.go:6:2: cannot find package "_/go/src/my-lib/vendor/github.com/go-sql-driver/mysql" in any of:
    /usr/local/go/src/_/go/src/my-lib/vendor/github.com/go-sql-driver/mysql (from $GOROOT)
    /go/src/_/go/src/my-lib/vendor/github.com/go-sql-driver/mysql (from $GOPATH)

And here is a public GitHub repo with my entire setup and installation steps: https://github.com/doomhz/my-go-project

Any idea how to fix this? Any help would be much appreciated. Thanks in advance.

you can put them back in multiple directory, but your docker file should look something like this..

FROM golang:alpine
WORKDIR /go/src/github.com/doomhz/my-go-project
COPY . .
RUN go get -d -v ./...
RUN go install -v ./...
ENTRYPOINT ["my-go-project"]
