# kube-health-monitoring

This is simple solution to monitor the health of your deplyoments in kuberenetes. It includes a cron job which will run 

every X minutes and check weather any of your deployments doesn't have running pods. If so it will send an alert message to slack.

### Deployment

Prerequisites

* kubectl 

First you need to create a configmap from the shell script. For that run

```bash

kubectl create configmap available-pods-check --from-file=available-pods-check.sh

```

Second we need to create cron job and service account for it. 

Please make sure to modify cron.yaml file and set the following env variables: 

* CHANNEL

* WEBHOOK (You can check [here](https://api.slack.com/messaging/webhooks) how to create Inbound Webhook for Slack)

Also you can change the schedule of cronjob which is set to run every 5 minutes.

After that go ahead and run 

```bash

kubectl apply -f cron.yaml

```

 

You can check that your cron has been created, and the last schedule by running

```bash

kubectl get cronjob available-pods-check

```

Stay healthy!
