Hands-On Microservices with Kotlin

Creating a database

We have now installed a MongoDB server that can handle several databases, but we are going to need one for our examples.

First, let's find out what databases exist using the show dbs command:

> show dbsadmin 0.000GBlocal 0.000GB

By default, there are two databases on our server: the admin database and the local database; these are system databases that Mongo requires to function:

• admin database: Holds different security and administration information
• local database: Stores the data required for this instance of our MongoDB server

Those two databases cannot be deleted, so we need to create our own, but first, we need to inform the client that we are going to use a different database using the use command:

> use microservices ...
