Finding a Cluster’s Endpoints
You can find a cluster’s cluster endpoint and reader endpoint using the Amazon DocumentDB console or AWS CLI.
Using the Console
To find a cluster’s endpoints using the console
- Sign in to the AWS Management Console, and open the Amazon DocumentDB console at https://console.aws.amazon.com/docdb.
- In the navigation pane, choose clusters.
- From the list of clusters, choose the name of the cluster you are interested in.
- Scroll down to the Details section and locate the cluster endpoint and the reader endpoint.
 ```
- To connect to this cluster, scroll up to the Connect section. Locate the connection string for the
mongoshell and a connection string that can be used in the application code to connect to your cluster.
 ```
Using the AWS CLI
To find the cluster and reader endpoints for your cluster using the AWS CLI, run the describe-db-clusters command with these parameters.
Parameters
--db-cluster-identifier—Optional. Specifies the cluster to return endpoints for. If omitted, returns endpoints for up to 100 of your clusters.--query—Optional. Specifies the fields to display. Helpful by reducing the amount of data that you need to view to find the endpoints. If omitted, all information about a cluster is returned.--region—Optional. Use the--regionparameter to specify the Region that you want to apply the command to. If omitted, your default Region is used.
The following example returns the DBClusterIdentifier, endpoint (cluster endpoint), and ReaderEndpoint for sample-cluster.
For Linux, macOS, or Unix:
1. aws docdb describe-db-clusters \
2. --region us-east-1 \
3. --db-cluster-identifier sample-cluster \
4. --query 'DBClusters[*].[DBClusterIdentifier,Port,Endpoint,ReaderEndpoint]'
For Windows:
1. aws docdb describe-db-clusters ^
2. --region us-east-1 ^
3. --db-cluster-identifier sample-cluster ^
4. --query 'DBClusters[*].[DBClusterIdentifier,Port,Endpoint,ReaderEndpoint]'
Output from this operation looks something like the following (JSON format).
1. [
2. [
3. "sample-cluster",
4. 27017,
5. "sample-cluster.cluster-corlsfccjozr.us-east-1.docdb.amazonaws.com",
6. "sample-cluster.cluster-ro-corlsfccjozr.us-east-1.docdb.amazonaws.com"
7. ]
8. ]
Now that you have the cluster endpoint, you can connect to the cluster using either mongo or mongodb. For more information, see Connecting to Endpoints.
