通过复制供应商文件夹构建golang

Question

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.

Answer 1

The normal way is to use a dependency manager such as dep.

An alternative is just to copy the vendor directory directly in your Dockerfile, but this is not ideal, as it will copy the entire vendor directory verbatim, even if it contains old or unused imports.
