Connect To The Aerospike Cluster

You can connect to an Aerospike cluster deployed by Aerospike Kubernetes Operator through Aerospike Admin (asadm) or through applications which use Aerospike client libraries.

Port Access

When the Aerospike cluster is deployed in a single pod per Kubernetes host mode(multiPodPerHost set to default of 'false'), ports 3000 (service port) and 4333 (TLS port) on all Kubernetes hosts should be accessible to all clients and tools.

When the Aerospike cluster is configured to have multiple pods per Kubernetes host mode(multiPodPerHost set to 'true'), port range (30000–32767) on all Kubernetes hosts should be accessible to all clients and tools.

Configure the firewall rules for the Kubernetes cluster accordingly.

See the Cluster Configuration Settings section for more information on using the multiPodPerHost setting.

Aerospike Node Endpoints

Use kubectl describe to get the IP addresses and port numbers:

 kubectl -n [namespace] describe aerospikecluster [Aerospike_cluster name]

For example, to get the IP addresses and port numbers for the cluster aerocluster in the aerospike namespace:

kubectl -n aerospike describe aerospikecluster aerocluster

The Status > Pods section provides pod-wise access, alternate access, TLS access, and TLS alternate access endpoints as well as TLS name (if TLS is configured) to be used to access the cluster.

$ kubectl -n aerospike describe aerospikecluster aerocluster

Connect to the Cluster

When connecting from outside the Kubernetes cluster network, you need to use the host external IPs. By default, the Operator configures access endpoints to use Kubernetes host internal IPs and alternate access endpoints to use host external IPs.

Refer to network policy configuration for details.

From the example status output, for pod aerocluster-0-0, the alternate access endpoint is 34.70.193.192:31312

With a Client

To use a client from outside the Kubernetes network using external IPs, set the following for the client policy using appropriate client API.

host: 34.70.193.192
port: :31312
username: admin
password: admin123 # based on the configured secret
use-services-alternate: true

To use asadm from within the Kubernetes network run:

host: 10.128.15.225
port: :31312
username: admin
password: admin123 # based on the configured secret
use-services-alternate: false

With asadm

With kubectl

kubectl run -it --rm --restart=Never aerospike-tool -n aerospike --image=aerospike/aerospike-tools:latest -- asadm -h [cluster name] -U [username] -P [password]

To use asadm from outside the Kubernetes network:

asadm -h 34.70.193.192:31312 -U [username] -P [password] --services-alternate

To use asadm from within the Kubernetes network:

asadm -h 10.128.15.225:31312 -U [username] -P [password]
