# Bookinfo Sample

See <https://istio.io/docs/examples/bookinfo/>.

**Note**: We need the owner of the PR to perform the appropriate testing with built/pushed images to their own docker repository before we would build/push images to the official Istio repository.

## General Setup

```bash
# This defines the docker hub to use when running integration tests and building docker images
# eg: HUB="docker.io/istio", HUB="gcr.io/istio-testing"

        // progress display name on the console, whereas we want to display both the progress display name and the status
        // This should be pushed down into the progress logger infrastructure so that an operation can have both a display name (that doesn't change) and
        // a status (that does)
        if (statusProgressLogger == null) {

	BuildClusters(node *model.Proxy, req *model.PushRequest) ([]*discovery.Resource, model.XdsLogDetails)

	// BuildDeltaClusters returns both a list of resources that need to be pushed for a given proxy and a list of resources
	// that have been deleted and should be removed from a given proxy. This is Delta CDS output.
	BuildDeltaClusters(proxy *model.Proxy, updates *model.PushRequest,

# This folder is then passed as the docker context. This avoids complex .dockerignore or large context loads.

# Example image config
example:
- name: helloworld # Name of the image. Will end up pushed to <HUB>/helloworld:<TAG>
  dockerfile: helloworld/Dockerfile.proxyv2
  files:
  # Include a static file
  # Inside the Dockerfile, this is referenced by the base name (README.md), not the full name.
