When build beego docker image with default docker file, show error: `godep: No Godeps found (or in any parent directory)`

Question

I'm new to Go & Beego.

When I build docker image with beego's default docker file, it shows this error :

godep: No Godeps found (or in any parent directory)

The build info is:

The solution is very simple: run godep save in your project locally, and you will go a new folder Godeps in your project. it contains file:Godeps.json. After this, run docker build . again, you will got your docker image.
