### CLI

To build the operator CLI, simply:

```bash
make build
```

Ensure the created binary is in your PATH to run the examples below.

### Controller (in cluster)

Building a custom controller requires a Dockerhub (or similar) account. To build using the container based build:

```bash
HUB=docker.io/<your-account> TAG=latest make docker.operator
```

# This repository has been enabled for BUILD_WITH_CONTAINER=1. Some
# test cases fail within Docker, and Mac + Docker isn't quite perfect.
# For more information see: https://github.com/istio/istio/pull/19322/

1. Config serving (XDS)

### Config Ingestion

Istio reads from over 20 different resources types, and aggregates them together to build the proxy configuration. These resources can be sourced from Kubernetes (via watches), files, or over xDS; Kubernetes is by far the most common usage, though.

Primarily for historical reasons, ingestion is split into a few components.
