prometheus-adapter/deploy/README.md

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:
