    Requirements for Couchbase Capella Links

    You need to take the following steps on your Couchbase Capella operational cluster:

    • To allow Enterprise Analytics to connect to a Couchbase Capella operational cluster, you must add the IP address of the Enterprise Analytics server to the Capella cluster’s "Allowed IP" list. For more information, see Add an Allowed IP Address.

    • Get the hostname or external IP address for 1 of the Couchbase Capella cluster nodes. You supply this value to Enterprise Analytics as the hostname/IP address.

    • Create a user and password for Enterprise Analytics to use when connecting. Give this user read/write permissions for all buckets and scopes you want to stream. For more information, see Create Cluster Access Credentials.

    • Save a copy of the Couchbase Capella cluster root certificate. You can find the certificate on the Capella UI at the Security Certificate page under Settings.

    • Note the names of the bucket, scope, and collection you want to stream to Enterprise Analytics.
