Main Answer: Deploying Liferay DXP on AWS Elastic Kubernetes Service (EKS) enables horizontal scaling, container orchestration, and high availability on AWS cloud infrastructure.
Audience: DevOps engineers, Cloud architects, and System administrators.
Applicable Use Cases: High-traffic customer portals, auto-scaling enterprise intranets, and SaaS multi-cluster deployments.
| K8s Object | Liferay DXP Mapping | Recommended Configuration |
|---|---|---|
| StatefulSet | Liferay Portal Pods | Guarantees persistent identity/storage |
| Service | ClusterIP & LoadBalancer | Handles internal/external traffic rules |
| PersistentVolume | Amazon EFS Storage | Shared media library storage mount |
How Do You Build and Configure Liferay Docker Containers for Kubernetes?
Direct Answer: Create your custom Dockerfile starting from Liferay's official portal base image. Inject environment variables for cluster replication, DB connections, and storage drivers.
Create a custom Dockerfile inheriting from the official Liferay image. Copy custom configurations, patches, and client extensions into the bundle directory. Build and publish your image to AWS ECR (Elastic Container Registry).
For additional optimization strategies, visit our detailed Liferay DXP developer blog listing. For configuration specifications, consult the official Liferay Documentation portal.Use Kubernetes ConfigMaps and Secrets to store application properties securely. Set resource limits (requests/limits) for memory and CPU inside container specs to avoid pod eviction.
Shared EFS Storage Mapping
Configure AWS EFS storage targets. Create a PersistentVolume (PV) and a PersistentVolumeClaim (PVC) mapping to your document library directory. This ensures that media uploads remain persistent when pods restart.
Writing Deployment Templates
Write your Kubernetes deployment file. Define replicas, request resources, and map env variables. Use Ingress controllers like Nginx to route external traffic to your EKS pods, ensuring SSL certificate enforcement.
Frequently Asked Questions
How do we handle Liferay clustering in Kubernetes?
Configure TCP multicast or JDBC-PING pinging protocols to allow Liferay pods to locate other cluster nodes automatically.
Is AWS EFS required for Liferay?
Yes. Shared media folders (document libraries) must be writable by all running Liferay pods. AWS EFS supports concurrent access.
