Configure network access to an OpenSearch cluster

By default, in clusters with a public subnet, connections are allowed from all IP addresses, provided a login and password are used.

Connections to a cluster in a private subnet are allowed from the cluster's subnet and from subnets associated with the cluster's subnet via a cloud router.

You can restrict access to a Managed Databases cluster using security groups.

Any changes to network access settings are the client's responsibility.

Security groups in a Managed Database cluster

A security group in a Managed Databases cluster is a set of rules for filtering incoming and outgoing cluster traffic. For security groups to work, traffic filtering (port security) must be enabled on the network.

If filtering is enabled in the network, all ports in this network are assigned the default security group, which allows all traffic through the ports. You can assign a different security group when creating a cluster or in an existing cluster.

In addition to the security groups you select when creating a cluster, a service security group is automatically assigned to the Managed Database cluster network ports. This group supports cluster operation and cannot be modified or deleted. The service group is only visible in the OpenStack CLI and Terraform.

Learn more about security groups in the Security groups section.

Assign a security group in an existing cluster

warning

After assigning the group, all active sessions that do not comply with the group's rules will be terminated.

  1. Make sure that traffic filtering (port security) is enabled on the cluster network. To do this, in the Control panel, from the top menu, click Products → Cloud Servers → Network → the Private networks or Public networks tab. A network with filtering enabled is marked with .

    If filtering is disabled, to use security groups, create a new cluster in a new subnet or in a subnet with traffic filtering enabled.

  2. In the Control panel, from the top menu, click Products and select Managed Databases.

  3. Open the Active tab.

  4. Open the database cluster page → Settings tab.

  5. In the Security block, click Edit.

  6. Select the security group you want to assign to all ports in the cluster network.
