Fiddle with go.mod to make dockerhub build it?

idk it stopped working with:

---> Running in 74be85315501
1mgo: cannot find main module, but found .git/config in /go/src/mypackage/myapp
to create a module there, run:
go mod init

Removing intermediate container 74be85315501
The command '/bin/sh -c go get -d -v' returned a non-zero code: 1
