Docker-Compose Up Fails... Cannot find package "gopkg.in/mgo.v2/bson

[markwk]

I wanted to about setting this up again with docker either on a Mac or on a Linux machine in the cloud. Running docker-compose up gave me this error:

Step 4/23 : RUN CGO_ENABLED=0 GOOS=linux go build -ldflags '-s' -a -installsuffix cgo -v -o server

Feels like some cleanup and updating needed in the compose or docker file?
