This section explains how to set up a sandbox deployment with AdminAPI. Initially deploying and using local sandbox instances of MySQL is a good way to start your exploration of AdminAPI. You can fully test out the functionality locally, prior to deployment on your production servers. AdminAPI has built-in functionality for creating sandbox instances that are correctly configured to work with InnoDB Cluster, InnoDB ClusterSet, and InnoDB ReplicaSet in a locally deployed scenario.
Sandbox instances are only suitable for deploying and running on your local machine for testing purposes. In a production environment the MySQL Server instances are deployed to various host machines on the network. See Section 7.4, “Deploying a Production InnoDB Cluster” for more information.
Unlike a production deployment, where you work with instances and specify them by a connection string, sandbox instances run locally on the same machine as which you are running MySQL Shell. Therefore, to specify a sandbox instance you supply the port number which the MySQL sandbox instance is listening on.
