This sample demonstrates how to use the Oracle WebLogic Server Kubernetes Operator (hereafter “the operator”) to set up a WebLogic Server (WLS) cluster on the Azure Kubernetes Service (AKS). After going through the steps, your WLS domain runs on an AKS cluster. You have several options for managing the cluster, depending on which domain home source type you choose. With Domain in PV, you can manage your WLS domain by accessing the WebLogic Server Administration Console or WLST. With Model in Image, you use the operator to perform WLS administrative operations.
Azure Kubernetes Service makes it simple to deploy a managed Kubernetes cluster in Azure. AKS reduces the complexity and operational overhead of managing Kubernetes by offloading much of that responsibility to Azure. As a hosted Kubernetes service, Azure handles critical tasks like health monitoring and maintenance for you. The Kubernetes masters are managed by Azure. You only manage and maintain the agent nodes. As a managed Kubernetes service, AKS is free - you only pay for the agent nodes within your clusters, not for the masters.

This sample demonstrates running the WebLogic cluster on AKS using two domain home types. The instructions for each are self-contained and independent. This section lists the domain home source types recommended for use with AKS, along with some benefits of each. For complete details on domain home source types, see Choose a domain home source type.
