In this article you will learn how to setup and deploy kwatch in your Kubernetes (K8s) cluster to monitor and receive real time crash alerts through PagerDuty

Configure PagerDuty

Step 1: Create a new service

Step 2: Give your service a Name and a Description

Step 3: Add an Escalation Policy

Step 4: Make sure to add the Events API V2 Integration

Step 5: Navigate to your service and copy the Integration Key

Configure kwatch

Step 1: Get the configuration template

curl  -L https://raw.githubusercontent.com/abahmed/kwatch/v0.3.0/deploy/config.yaml -o config.yaml

Step 2: Edit `config.yaml` file and add the Integration Key

apiVersion: v1
kind: Namespace
metadata:
  name: kwatch
---
apiVersion: v1
kind: ConfigMap
metadata:
  name: kwatch
  namespace: kwatch
data:
  config.yaml: |
    alert:
      pagerduty:
        integrationKey: <integration_key>

Step 3: Apply the configuration

kubectl apply -f config.yaml

Deploy kwatch

kubectl apply -f https://raw.githubusercontent.com/abahmed/kwatch/v0.3.0/deploy/deploy.yaml

You will now start receiving PagerDuty alerts whenever there is a pod crash in your Kubernetes (K8s) cluster!
