etcd Watch example using Go client

etcd is a distributed, highly available key-value store which serves as the persistent back end for Kubernetes

Here is an example to demonstrate its Watch feature. For details, check out the README (and the sample code) on Github

It uses

• etcd Docker image
• etcd Go client

Summary

• a watch is set, and …
• … the channel is used to listen to events
• a separate goroutine is spawned to trigger key modification which in turn generates events

Cheers!
