Introduction

This document provides information about the system requirements and limitations for deploying and running OIG domains with the WebLogic Kubernetes Operator 3.0.1.

In this release, OIG domains are supported using the “domain on a persistent volume” model only, where the domain home is located in a persistent volume (PV).

System requirements for OIG domains

A running Kubernetes cluster with Helm and Docker installed. For the minimum version requirements refer to document ID 2723908.1 on My Oracle Support.
You must have the cluster-admin role to install the operator.
We do not currently support running OIG in non-Linux containers.
A running Oracle Database 12.2.0.1 or later. The database must be a supported version for OIG as outlined in Oracle Fusion Middleware 12c certifications. It must meet the requirements as outlined in About Database Requirements for an Oracle Fusion Middleware Installation and in RCU Requirements for Oracle Databases.
Java Developer Kit (11.0.3 or later recommended)

Limitations

Compared to running a WebLogic Server domain in Kubernetes using the operator, the following limitations currently exist for OIG domains:

The “domain in image” model is not supported.
Only configured clusters are supported. Dynamic clusters are not supported for OIG domains. Note that you can still use all of the scaling features, you just need to define the maximum size of your cluster at domain creation time.
Deploying and running OIG domains is supported only with WebLogic Kubernetes Operator version 3.0.1 currently supports the WebLogic MBean trees only.
The WebLogic Monitoring Exporter currently supports the WebLogic MBean trees only. Support for JRF MBeans has not been added yet.
