In this section, you’ll find end-to-end tutorials for managing MongoDB on 123cluster. You’ll start by initializing a new replica-set and adding standby members, then move on to creating databases and provisioning dedicated backup nodes. From there, you’ll master operational tasks such as starting/stopping nodes, stepping down a primary, and performing exports and restores (both backup and export workflows). Finally, you’ll learn how to copy a database and safely tear down resources by dropping nodes, databases, backups, and exports. By the end, you’ll be fully equipped to automate every aspect of a MongoDB deployment via 123cluster’s UI and underlying REST API.
