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

This builds the controller binary and docker file, and pushes the image to the specified hub with the `latest` tag.
Once the images are pushed, configure kubectl to point to your cluster and install the controller.

Install the controller manifest:

```bash

"spaceLength": 10, "stack": true, "steppedLine": false, "targets": [ { "expr": "sum(irate(pilot_xds_pushes{type=\"cds\"}[1m]))", "format": "time_series", "intervalFactor": 1, "legendFormat": "Cluster", "refId": "C" }, { "expr": "sum(irate(pilot_xds_pushes{type=\"eds\"}[1m]))", "format": "time_series", "intervalFactor": 1, "legendFormat": "Endpoints", "refId": "D" }, { "expr": "sum(irate(pilot_xds_pushes{type=\"lds\"}[1m]))", "format": "time_series", "intervalFactor": 1, "legendFormat": "Listeners",...

Note that clients can actually send three types of messages - requests, ACKs of previous pushes, and NACKs of previous pushes. Unfortunately, these are not clearly distinguished in the API, so there is some logic to split these out (`shouldRespond`).
