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.

RBAC and Networking Requirements

Preparing the Kubernetes cluster to run the Operator may require setting up proper RBAC and network settings in your Kubernetes cluster. Before moving forward, review the following documentation:

Next Steps

As you’re setting up your Kubernetes environment, make sure that you’re following the recommended best practices.

Once your Kubernetes environment is set up, you can move on to installing the admission controller and the Operator.
