Apache NiFi on Kubernetes provides powerful data flow automation with production-grade scalability. Here's how we deploy it on EKS for enterprise clients.
Why NiFi on EKS?
Running NiFi on EKS gives you auto-scaling, high availability across AZs, integrated IAM for S3/Kinesis access, and easy integration with the rest of your AWS data stack.
Prerequisites
- EKS cluster (1.28+) with at least 3 nodes (m5.xlarge minimum)
- EBS CSI driver for persistent volumes
- ALB ingress controller for HTTPS access
- Cert-manager for TLS certificates
Helm Deployment
Use the official Apache NiFi Helm chart with these key configurations: - Set replicas to 3 for HA with ZooKeeper - Use EBS gp3 volumes for repositories (10Gi minimum per node) - Enable OIDC or LDAP authentication — never run NiFi without auth - Set resource requests: 4 CPU, 8Gi memory per pod
Persistent Storage
NiFi needs persistent storage for flowfile repos, content repos, and provenance repos. Use separate EBS volumes for each to maximize I/O performance.
Security Hardening
- Enable TLS between NiFi nodes with auto-generated certificates
- Use AWS Secrets Manager for sensitive processor properties
- Apply network policies to restrict NiFi pod egress
- Enable NiFi's built-in authorization with admin user setup
Monitoring
Deploy Prometheus with NiFi metrics reporter. Key metrics to watch: active threads, flow file count, backpressure thresholds, and bulletin errors.
