Deploy Camunda 7 on Kubernetes – Step by Step Guide

 Deploying Camunda 7 on Kubernetes is the best way to run BPM workflows in a scalable and production-ready environment.

In this guide, you will learn:

• Prerequisites

• Kubernetes deployment using Helm

• Database configuration

• Accessing Camunda Web Apps

• Production best practices

---

📌 What is Camunda 7?

Camunda 7 is an open-source BPM platform that supports:

• BPMN 2.0

• DMN

• CMMN

• Embedded & Standalone deployment

It is widely used for workflow automation in enterprise systems.

---

🧰 Prerequisites

Before deploying, ensure you have:

• Kubernetes cluster (Minikube / AKS / EKS / GKE)

• kubectl installed

• Helm installed

• PostgreSQL or external DB

• Docker (optional for custom image)

---

🛠 Step 1: Add Camunda Helm Repository

Camunda provides official Helm charts.

helm repo add camunda https://helm.camunda.io
helm repo update

---

🛠 Step 2: Create Namespace

kubectl create namespace camunda

---

🛠 Step 3: Install Camunda 7 via Helm

helm install camunda camunda/camunda-platform \
  --namespace camunda

This deploys:

• Camunda Webapps

• REST API

• Embedded H2 Database (default)

---

🛠 Step 4: Check Running Pods

kubectl get pods -n camunda

You should see pods like:

• camunda-platform-xxx

• postgresql-xxx

---

🛠 Step 5: Expose the Service

To access Camunda locally:

kubectl port-forward svc/camunda-platform 8080:80 -n camunda

Now open:

http://localhost:8080

Default login:

demo / demo

---

🛠 Step 6: Configure External Database (Production)

For production, do NOT use H2.

Edit values.yaml:

postgresql:
  enabled: true
  postgresqlUsername: camunda
  postgresqlPassword: camunda
  postgresqlDatabase: camunda

Then upgrade:

helm upgrade camunda camunda/camunda-platform \
  -f values.yaml \
  --namespace camunda

---

🛠 Step 7: Enable Ingress (Optional)

If running on cloud:

ingress:
  enabled: true
  hosts:
    - name: camunda.yourdomain.com

Apply upgrade again.

📷 Camunda 7 Web Apps on Kubernetes

You can access:

• Cockpit

• Tasklist

• Admin

• REST API

---

🔐 Production Best Practices

✔ Use external PostgreSQL
✔ Enable persistent volumes
✔ Configure resource limits
✔ Use Ingress + HTTPS
✔ Secure with Keycloak / OAuth
✔ Disable demo user

---

⚡ Scaling Camunda 7

Increase replicas:

replicaCount: 3

Then:

helm upgrade camunda camunda/camunda-platform -n camunda

Kubernetes will load balance traffic automatically.

---

🧪 Troubleshooting

Check logs:

kubectl logs <pod-name> -n camunda

Common issues:

• DB connection failure

• Wrong namespace

• Insufficient memory

---

📋 Deployment Checklist

✔ Helm installed
✔ Namespace created
✔ Database configured
✔ Pods running
✔ Service exposed
✔ Ingress enabled

---

🎯 Conclusion
