godep不安装必需的软件包

I'm trying to run the application (written in Go) inside docker. To install dependencies I'm using godep. When executing godep inside docker, following error is received

 docker run -ti --rm -v $PWD:/go/src/app -p3000:3000 golang bash 
 root@7c491d184712:/go/src/app# go get github.com/tools/godep 
 root@7c491d184712:/go/src/reno# godep save 
 godep: Package (github.com/Shopify/sarama) not found

Godep needs you to have local copies of the dependencies you want to vendor. You should run go get before running godep save. Additionally, assuming you have sub-packages in your app folder, you should run godep save ./....
