Migrating to Operator

What has changed

IMC controller worked on the basis of annotations on the routes or ingresses. That is obsolete now and the whole lifecycle and additional configuration for monitors are now managed by EndpointMonitor custom resource. Provider specific annotations are now part of Custom Resource now:

apiVersion: endpointmonitor.stakater.com/v1alpha1
kind: EndpointMonitor
metadata:
  name: uptimerobot-config-example
spec:
  forceHttps: true
  providers: "UptimeRobot"
  healthEndpoint: "/healthzzz"
  urlFrom:
    routeRef:
      name: frontend
  uptimeRobotConfig:
    interval: 600
    monitorType: "http"
    KeywordExists: "yes"
    KeywordValue: "404"

Old way of using it with Controller:

apiVersion: v1
kind: Route
metadata:
  name: frontend
  annotations:
    monitor.stakater.com/enabled: true
    uptimerobot.monitor.stakater.com/interval: 600
    uptimerobot.monitor.stakater.com/monitor-type: 'http'
    uptimerobot.monitor.stakater.com/keyword-exists: 'yes'
    uptimerobot.monitor.stakater.com/keyword-value: '404'
spec:
  to:
    kind: Service
    name: hello-openshift
  port:
    targetPort: http
  tls:
    termination: edge
    insecureEdgeTerminationPolicy: Redirect
  wildcardPolicy: None
