When managing large distributed databases, administrators often don't have time to go through setup wizards when deploying new software. Couchbase Server provides a RESTful API for provisioning instances, including creating new clusters or joining existing ones. To configure a new cluster, administrators can use the `curl` command to define memory allocation, services availability, and create an administrative account. They can also create buckets with specific settings, such as bucket type, ram quota, and authentication type. Additionally, the RESTful API allows administrators to join existing clusters and rebalance the cluster after adding or removing nodes. By utilizing these API endpoints, administrators can automate the configuration process using scripts, making it easier to manage large-scale deployments.
