Example Deployment
==================
1. Make sure you've built the included Dockerfile with `TAG=latest make container`. The image should be tagged as `gcr.io/k8s-staging-prometheus-adapter:latest`.

2. Create a secret called `cm-adapter-serving-certs` with two values:
`serving.crt` and `serving.key`. These are the serving certificates used
by the adapter for serving HTTPS traffic. For more information on how to
generate these certificates, see the [auth concepts
documentation](https://github.com/kubernetes-incubator/apiserver-builder/blob/master/docs/concepts/auth.md)
in the apiserver-builder repository.
The kube-prometheus project published two scripts [gencerts.sh](https://github.com/prometheus-operator/kube-prometheus/blob/62fff622e9900fade8aecbd02bc9c557b736ef85/experimental/custom-metrics-api/gencerts.sh)
and [deploy.sh](https://github.com/prometheus-operator/kube-prometheus/blob/62fff622e9900fade8aecbd02bc9c557b736ef85/experimental/custom-metrics-api/deploy.sh) to create the `cm-adapter-serving-certs` secret.
