Docker images are now created.

## Push docker images to docker hub

After the local build is successful, you will need to push the images to Docker hub.  You may need to login to Docker before you run the command using `docker login`.

```bash
cd samples/bookinfo
BOOKINFO_LATEST=true BOOKINFO_TAG=$TAG BOOKINFO_HUB=$HUB src/build-services.sh --push
```

For example:

```bash

	// may be safely recycled.
	popped atomic.Uint32

	// spans is the set of spans in this block.
	spans [spanSetBlockEntries]atomicMSpanPointer
}

// push adds span s to buffer b. push is safe to call concurrently
// with other push and pop operations.
func (b *spanSet) push(s *mspan) {
	// Obtain our slot.
	cursor := uintptr(b.index.incTail().tail() - 1)
	top, bottom := cursor/spanSetBlockEntries, cursor%spanSetBlockEntries

	defer s.Unlock()
	for _, client := range s.clients {

			select {
			case client.XdsConnection().PushCh() <- secretName:
			case <-client.XdsConnection().StreamDone():
			}
		}(client)
