# Example Deployment

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

2. `kubectl create namespace monitoring` to ensure that the namespace that we're installing
   the custom metrics adapter in exists.

3. This can be deployed via `kubectl create -f manifests/` or via `kustomize`
   a. if using `kubectl create -f manifests/` modify the Deployment as necessary to point to your Prometheus server, and the ConfigMap to contain your desired metrics discovery configuration.
   b. if using `kustomize` reference the kustomization file located: `http://github.com/kubernetes-sigs/prometheus-adapter/deploy?ref=release-X.XX`
   example kustomization.yaml:

   ```kustomization.yaml
   ---
   apiVersion: kustomize.config.k8s.io/v1beta1
   kind: Kustomization
