Oracle enables organizations using Coherence to move their clusters into the cloud. By supporting industry standards, such as Docker and Kubernetes, Oracle facilitates running Coherence on cloud-neutral infrastructure. In addition, Oracle provides an open-source Coherence Operator (“the operator”), which implements features to assist with deploying and managing Coherence clusters in a Kubernetes environment. You can:
The current version of the Coherence Operator is 3.0.2
The Coherence Operator is a Go based application built using the Operator SDK
Deploy Coherence clusters into Kubernetes using a custom resource definition
Flexibly override and customize cluster configuration.
Safely scale the Coherence deployments using standard Kubernetes tools such as the
kubectl scale command.
Use Kubernetes Zone information to ensure data stored in Coherence is resilient to loss of a Zone. Coherence goes to great efforts to ensure data is safe across processes, machines, racks and sites. When Coherence is deployed to Kubernetes with the Coherence Operator, data will be spread across zones to ensure this underlying principle is supported; thus by default, loss of any zone is a tolerated failure mode. This is reflected in the StatusHA value (SITE-SAFE) for partitioned services, in addition to the member level site information that is equivalent to the kubernetes zone label on the associated pod.
Use Kubernetes persistent volumes when using Coherence’s disk-based storage features Elastic Data or Persistence.
Deploy custom code for your server side classes.
Use Coherence*Extend to access your cluster with a variety of clients.
The fastest way to experience the operator is to follow the Quick Start guide
We have a public Slack channel where you can get in touch with us to ask questions about using the operator or give us
feedback or suggestions about what features and improvements you would like to see.
We would love to hear from you. To join our channel, please
visit this site to get an invitation.
The invitation email will include details of how to access our Slack workspace.
After you are logged in, please come to
#operator and say, “hello!”
