Prerequisites and System Requirements

    +

    To install the Couchbase Autonomous Operator, all you need is a running Kubernetes or OpenShift cluster.

    If you don’t have access to a Kubernetes cluster, but still want to use the Operator for development, Minikube (single-node Kubernetes cluster) and Minishift (single-node OpenShift cluster) make great alternatives. Both of these products are much easier to install and deploy when compared to setting up and running an actual Kubernetes or OpenShift cluster.

    Platform Compatibility

    Support Level Definitions:
    Certified

    Couchbase has performed an extensive testing and review process to make sure that the Operator runs well out of the box on the specified platform.

    Supported

    Couchbase believes that the Operator will run well out of the box on the specified platform, but extensive testing has not been performed. Couchbase will make a best effort to investigate issues on a Supported platform version, but it is recommended that you run the Operator on a Certified platform version.

    Developer Preview

    Couchbase is still developing functionality for the specified platform, but you are encouraged to start your own testing and provide early feedback.
