Monitoring Kubernetes with Statuscake

Statuscake push monitors are a basic (and free) check that can be setup to make sure your kube-scheduler is functioning correctly.

This guide will show you how to create a Kubernetes job that launches a curl command to your Statuscake push monitor.

Prerequisites :

Free Statuscake account with a contact group setup.
Kubernetes Cluster with kubectl setup on your local machine.

Statuscake setup

Select a test type of PUSH, add your test name and contact group. Save your new monitor. Save the Push URL for later.

Kubernetes Setup

Create a secret with your Statuscake push URL by running the following command:

kubectl create secret generic statuscake \
--from-literal=url="<Your push URL>"

Create statuscake-cronjob.yml or

kubectl apply -f https://raw.githubusercontent.com/adamhancock/statuscake-push-k8s/master/statuscake-cronjob.yaml

              imagePullPolicy: IfNotPresent
              args:
                - /bin/sh
                - -c
                - wget -q "$(statuscake)"
          restartPolicy: OnFailure

statuscake-cronjob.yml

Run kubectl apply to create the cronjob

kubectl apply -f statuscake-cronjob.yml
