 * Git (1.8 or later recommended)
-* Java Developer Kit (1.8u131 or later recommended; please use 1.8, tests will not work on 1.9 or later versions)

 Because the target runtime environment for the operator is Oracle Linux, no particular effort has been made to ensure the build or tests run on any other operating system.  Please be aware that Oracle will not provide support, or accept pull requests to add support, for other operating systems.

 * _Host Path Persistent Volumes:_ If using a `hostPath` persistent volume, then it must be available on all worker nodes in the cluster and have read/write/many permissions for all container/pods in the WebLogic Server deployment.  Be aware
   that many cloud provider's volume providers may not support volumes across availability zones.  You may want to use NFS or a clustered file system to work around this limitation.
