Code examples for connecting to a MongoDB cluster

Examples were tested in the following environment:

• Yandex Cloud virtual machine running Ubuntu 20.04 LTS
• Bash: 5.0.16
• Python: 3.8.2; pip3: 20.0.2
• PHP: 7.4.3
• OpenJDK: 11.0.8; Maven: 3.6.3
• Node.JS: 10.19.0, npm: 6.14.4
• Go: 1.13.8

To see code examples with the host FQDN filled in, open the cluster page in the management console and click Connect.

All examples assume that the root.crt SSL certificate is located in the /home/<home_directory>/.mongodb/ directory.

If the connection to the cluster and the test query are successful, the following data is output:

• For PHP examples, the ping command result.
• For other examples, the name of the database the connection was established to.

Available connection methods depend on whether the cluster sharding is enabled:

• Examples for connection to a non-sharded cluster
• Examples for connection to a sharded cluster
