WebLogic Server Certification For Kubernetes

  Oracle has certified the deployment of WebLogic Server 12.2.1.3 domains running on Kubernetes. Kubernetes, Docker, Oracle Linux host operating system versions and kernel versions that have been certified are described below. The WebLogic Server on Kubernetes certification includes and requires using the Flannel network fabric in Kubernetes.
WebLogic Server
JDK
Host OS
Kubernetes
Docker
Network Fabric
12.2.1.3
8
Oracle Linux 7  UEK 4
1.7.5 and 1.8.0
17.03-ce
Flannel  v0.9.1-amd64
 Oracle has certified and support the following WebLogic configurations and features:
• Running one or more WebLogic domains in a Kubernetes cluster
• Single or multiple node Kubernetes clusters
• WebLogic Managed Servers in Clustered and Non Clustered configurations
• WebLogic Server Configured Clusters (vs Dynamic Clusters). See documentation for details.
• Unicast WebLogic Server cluster messaging
• Load balancing HTTP requests using Træfik as Ingress controllers in Kubernetes clusters
• HTTP Session replication
• JDBC communication with external database systems
• JMS
• JTA
• JDBC store and File store using Persistent Volumes
• Inter Domain communication (JMS, Transactions, EJBs,…)
• Auto-scaling of a WebLogic cluster
• Integration with Prometheus monitoring using the WebLogic Monitoring Exporter
• RMI communication from outside/inside the Kubernetes cluster
• Upgrading Applications
• Patching WebLogic domain
• Service migration of singleton services
• Database leasing
In this certification of WebLogic Server on Kubernetes, the following configurations and features are not supported:
• WebLogic domains spanning Kubernetes clusters
• Whole Server Migration
• Use of Node Manager for WebLogic Servers lifecycle management (start/stop)
• Consensus leasing
• Dynamic Clusters (will add certification of Dynamic Clusters at a future date)
• MultiCast WebLogic Server cluster messaging
• Multitenancy
• Production Redeployment
