1The MongoDBContainer class has a constructor that takes a Docker image name as a parameter. This class also has a static method getDefaultImage() that returns the default Docker image name. So, you can use the following code to create a MongoDBContainer object:2MongoDBContainer mongo = new MongoDBContainer(3    MongoDBContainer.getDefaultImage());4The following code shows how to use the start() method of the MongoDBContainer class to start a MongoDB container:5mongo.start();6The following code shows how to use the getReplicaSetUrl() method of the MongoDBContainer class to get the replica set URL:7String replicaSetUrl = mongo.getReplicaSetUrl();8The following code shows how to use the getShardUrl() method of the MongoDBContainer class to get the shard URL:9String shardUrl = mongo.getShardUrl();10The following code shows how to use the getDatabaseName() method of the MongoDBContainer class to get the database name:11String databaseName = mongo.getDatabaseName();12The following code shows how to use the getReplicaSetName() method of the MongoDBContainer class to get the replica set name:13String replicaSetName = mongo.getReplicaSetName();14The following code shows how to use the getShardName() method of the MongoDBContainer class to get the shard name:15String shardName = mongo.getShardName();16The following code shows how to use the getUsername() method of the MongoDBContainer class to get the username:17String username = mongo.getUsername();18The following code shows how to use the getPassword() method of the MongoDBContainer class to get the password:19String password = mongo.getPassword();20The following code shows how to use the getMongoClient() method of the MongoDBContainer class to get the MongoDB client:
