go get github.com/jcnnghm/cmdtrack
First, download the google cloud sdk from https://cloud.google.com/sdk/. Unzip it and move the directory to ~/google-cloud-sdk. Then run ~/google-cloud-sdk/install.sh to install it - it's already setup in shared.rc. Open a new shell so gcloud gets added to the path.
From there, these are the commands I used:
cd go/src/github.com/jcnnghm/cmdtrack
gcloud config set project cmdtrack-1127
go get ./...
cd server
go get github.com/gorilla/context
gcloud app deploy
