After much hard work from @cbro and others, we have a new landing page and tutorials for Go:
These samples demonstrate building and launching fully idiomatic Go servers using Managed VMs (like App Engine, but uses Docker for containerization).
The best part: No Google lock-in. The Hello World sample is straight out of the Go standard library. No Google-only or App Engine-only libraries required. The Bookshelf sample demonstrates 3 options for storage (CloudSQL, MongoDB and Cloud Datastore). The samples use the standard MySQL and MongoDB drivers.
We’d love your feedback. Use this thread or find us on the Gophers slack on the #appengine channel.
