通过复制供应商文件夹构建golang

My Project structure

/github.com/user
 - libraries
 - services
     - service-api-signup
          - Dockerfile
          - main.go
     - service-api-second
          - ...
 - vendor

Docker file inside service-api-signup

FROM golang
COPY . /go/src/github.com/user/services/service-api-signup

# need to copy all the dependencies on vendor to /go/src/github.com/..

How can copy all my dependencies on vendor and libraries folder to go path on docker image to build ? (need to copy from parent directory and build)

Any way to setup my development environment ?

Thanks.
