how to deploy the load-watcher as a service?

[colocasia98]

Hi all,
I found this line in README:
kubectl create -f manifests/load-watcher-deployment.yaml
but I did not find the manifests/load-watcher-deployment.yaml in repo.
Maybe a sample deployment file is needed?
thanks.

load-watcher-deployment.yaml can be something like:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: load-watcher-deployment
  labels:
    app: load-watcher
spec:
  replicas: 1
  selector:
    matchLabels:
      app: load-watcher
  template:
    metadata:
      labels:
        app: load-watcher
    spec:
      containers:
      - name: load-watcher
        image: [load-watcher image]
        env:
        - name: METRICS_PROVIDER_NAME
          value: [eg. SignaFx]
        - name: METRICS_PROVIDER_ADDRESS
          value: [metrics_provider_endpoint]
        - name: METRICS_PROVIDER_TOKEN
          value: [token]
        - name: SIGNALFX_CLUSTER_NAME
          value: [cluster_name]
        ports:
        - containerPort: 2020

you may need rbac if you are using metrics server

apiVersion: v1
