Suppose you have a Kubernetes cluster up and running. You want to deploy a docker container (https://hub.docker.com/repository/docker/aliakkas/karatepdi). Karatepadi is a Spring Boot Rest application for automating ETL testing using Behaviour Driven Development framework Karate and embedded Pentaho Data Integration engine. You can use it to execute PDI job/transformation or running Karate feature file to produce cucumber reports.
Prerequisites
- working kubernetes cluster with kubectl configured
- locally installed kubectl and helm commands
- RBAC authorisation already setup
- docker image of karatepdi.1.0.0
Setting up karatepdi
Keep etl resources together by creating a namespace called ‘etl’.
- create a file called etl/namespaces.yml with the following content:
kind: Namespace
apiVersion: v1
metadata:
name: etl- apply and test the namespace exists
$ kubectl get namespaces -n etl
etl Active 2d- deploy karatepdi
create a file called etl/pdi.yml with the following content:
apiVersion: "apps/v1"
kind: "Deployment"
metadata:
name: "pdi"
namespace: "etl"
labels:
app: "pdi"
spec:
replicas: 1
selector:
matchLabels:
app: "pdi"
template:

labels:
app: "pdi"
spec:
containers:
- name: "karatepdi"
image: "docker.io/aliakkas/karatepdi:1.0.0"
imagePullPolicy: "IfNotPresent"
resources: {}
ports:
- containerPort: 9999
status: {}- test the deployment
$ kubectl create -f ~/apps/docker/pdi.yml
verify that the PODs are running
$ kubectl get pods -n etl
