This operator automatically creates uptime monitors at UptimeRobot for your Kubernetes Ingress resources. This allows you to easily integrate uptime monitoring of your services into your Kubernetes deployments.

⚠️ This project is still in an early phase. Use it on your own risk but make sure to create issues for issues you encounter.

❤️ to UptimeRobot for providing a pro account to be able to test the pro plan features!

After installing the uptimerobot-operator it'll watch for Ingress resources in your Kubernetes cluster. For example after creating the following Ingress

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: my-ingress
  annotations:
    uroperator.brennerm.github.io/monitor.type: HTTPS
    uroperator.brennerm.github.io/monitor.interval: "600"
spec:
  rules:
  - host: brennerm.github.io
    http:
      paths:
      - pathType: Prefix
        path: "/"
        backend:
          service:
            name: service1
            port:
              number: 80

a new monitor for the URL https://brennerm.github.io is automatically being created in your UptimeRobot account.

The same monitor can also be created using the UptimeRobotMonitor resource like so:

apiVersion: uroperator.brennerm.github.io/v1beta1
kind: UptimeRobotMonitor
metadata:
  name: my-custom-monitor
spec:
  url: "https://brennerm.github.io"
  type: HTTPS
  interval: 600

The operator also supports creating public status pages. See below for details.

1. Create an or login to your UptimeRobot account (no credit card required and they provide up to 50 monitors for free)
2. Go to "My Settings"
3. Generate and save "Main API Key" (the other API keys do not provide sufficient permissions to create, update and delete monitors)

1. Add the uptimerobot-operator chart repo helm repo add uptimerobot-operator https://brennerm.github.io/uptimerobot-operator/helm
2. Deploy the Helm chart helm upgrade --install uptimerobot-operator uptimerobot-operator --set uptimeRobotApiKey=$MY_UPTIMEROBOT_API_KEY

Have a look at the values file if you want to customize the deployment.

ℹ️ The following commands will make the operator work with your currently selected Kubernetes cluster (kubectl config current-context).

1. Install all dependencies pipenv install
2. Set UptimeRobot API key export UPTIMEROBOT_API_KEY=$MY_UPTIMEROBOT_API_KEY
3. Start operator kopf run --standalone ur_operator/handlers.py

1. Build Docker image docker build -t uptimerobot-operator .
2. Start container docker run -e UPTIMEROBOT_API_KEY=$MY_UPTIMEROBOT_API_KEY -v ~/.kube:/home/ur_operator/.kube uptimerobot-operator

1. Start container docker run -e UPTIMEROBOT_API_KEY=$MY_UPTIMEROBOT_API_KEY -v ~/.kube:/home/ur_operator/.kube ghcr.io/brennerm/uptimerobot-operator:latest

The UptimeRobotMonitor resource supports all current parameters for monitors that UptimeRobot offers. Below you can find a list that contains all of them.

For Ingress resources the same parameters are supported. You pass them through annotations attached to your Ingress with the prefix uroperator.brennerm.github.io/monitor.. See below for an example.

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: my-ingress
  annotations:
    uroperator.brennerm.github.io/monitor.type: HTTPS
    uroperator.brennerm.github.io/monitor.interval: "600"
spec:
  rules:
...

To disable ingress handling completely pass the environment variable URO_DISABLE_INGRESS_HANDLING=1 to the operator.

The PublicStatusPage resource supports all current parameters for status pages that UptimeRobot offers. Below you can find a list that contains all of them.

apiVersion: uroperator.brennerm.github.io/v1beta1
kind: PublicStatusPage
metadata:
  name: my-public-status-page
spec:
  monitors: "0" # will include all monitors

The MaintenanceWindow resource supports all current parameters for maintenance windows that UptimeRobot offers. Below you can find a list that contains all of them.

apiVersion: uroperator.brennerm.github.io/v1beta1
kind: MaintenanceWindow
metadata:
  name: my-maintenance-window
spec:
  type: DAILY
  startTime: "10:00"
  duration: 30

The AlertContact resource supports all current parameters for alert contacts that UptimeRobot offers. Below you can find a list that contains all of them.

apiVersion: uroperator.brennerm.github.io/v1beta1
kind: AlertContact
metadata:
  name: my-alert-contact
spec:
  type: EMAIL
  value: foo@bar.com
