XDR for Aerospike on Kubernetes
To deploy a cluster as a cross-datacenter replication (XDR) source, configure auth-password-file
, auth-user
, auth-mode
and node-address-port
in the aerospikeConfig.xdr.dcs
section of the CR file.
After updating these configurations in the CR file, apply the CR file to deploy the cluster.
For more information, see the documentation on cross-datacenter replication (XDR).
Enable XDR and create a remote datacenter (DC)
This example is the XDR-specific configuration section for the Aerospike cluster CR file.

For the full CR file, see the example XDR CR.
This and other example CRs are available in the main Aerospike Kubernetes Operator repository.
Remote DC password file
If the destination cluster has security enabled, then aerospike-secret
created in this section should also have a password_DC1.txt
file containing the password for the destination DC.

Server versions
Aerospike Database instances in different destination clusters can run different versions of the database. For example, if you have clusters running Database 6.0, you can add a new cluster with the latest version and preserve XDR functionality.
