Binding or Unbinding an EIP

Scenario

After creating a CDM cluster, you can bind an EIP to or unbind an EIP from the cluster. The EIP is billed based on the VPC service.

If CDM needs to access a local or Internet data source, or a cloud service in another VPC, bind an EIP to the CDM cluster or use a NAT gateway to enable the CDM cluster to share the EIP with ECSs to access the Internet. For details, see Adding an SNAT Rule.

If SSL encryption is configured for the access channel of a local data source, CDM cannot connect to the data source using the EIP.

Prerequisites

• You have created a CDM cluster.
• Your EIP quota is sufficient.

Procedure

1. Log in to the CDM console and choose Cluster Management in the left navigation pane.

   Another method: Log in to the DataArts Studio console by following the instructions in Accessing the DataArts Studio Instance Console. On the DataArts Studio console, locate a workspace and click DataArts Migration to access the CDM console.
