This post outlines how to establish connectivity between two Aerospike clusters by leveraging Aerospike's Cross Datacenter Replication (XDR) feature to seamlessly transmit data from a source cluster to a destination cluster, providing high availability for critical data systems.

Ensuring network visibility for Aerospike service ports in the remote data center from a source cluster is crucial. However, this can pose challenges, especially in a Kubernetes environment. Fortunately, there is a solution: deploying a proxy server in front of the private Kubernetes destination cluster. To showcase this solution, we recommend installing the Kubernetes Operator to facilitate the creation and scheduling of the source and destination databases. While the demonstration is on setting up replication in one direction, it's worth noting that Aerospike supports active-active replication. This is accompanied by a conflict resolution mechanism to handle update clashes. This XDR proxy also supports this feature as well.

Let's begin the process.

Fig. 1 Aerospike Kubernetes Operator

The following Kubernetes nodes have been created using EKS.

First, display the following private and public IP addresses from listing the nodes with the kubectl command.

kubectl get nodes -o wide

Now, get a copy of the Aerospike git repo for the Kubernetes Operator.

git clone \ https://github.com/aerospike/aerospike-kubernetes-operator.git
cp features.conf \ aerospike-kubernetes-operator/config/samples/secrets/.

Setup

Run the following commands in the order specified. Wait for the CSV “Succeeded phase” to appear after running this line. Initially, it might take between 30 seconds and a minute to show up.

kubectl get csv -n operators -w

cd aerospike-kubernetes-operator/
kubectl apply -f config/samples/storage/eks_ssd_storage_class.yaml
curl -sL \
https://github.com/operator-framework/operator-lifecycle-manager/releases/download/v0.22.0/install.sh | bash -s v0.22.0
kubectl create -f \
https://operatorhub.io/install/aerospike-kubernetes-operator.yaml
kubectl get csv -n operators -w
cd..
git clone \ https://github.com/nareshmaharaj-consultant/kubernetes-anything
cd kubernetes-anything
./createNamespace.sh aerospike
cd ../aerospike-kubernetes-operator/
kubectl -n aerospike create secret generic aerospike-secret \
--from-file=config/samples/secrets
kubectl -n aerospike create secret generic auth-secret \
--from-literal=password='admin123'

Destination Cluster

Use the following YAML configuration file for our destination cluster. Save the file and name it ssd1_xdr_dest_6.1_cluster_cr.yaml:

apiVersion: asdb.aerospike.com/v1beta1
kind: AerospikeCluster
metadata:
  name: aerocluster-dest-xdr

        secretName: auth-secret
        roles:

    namespaces:
      - name: test
        memory-size: 134217728

          filesize: 1073741824
          data-in-memory: true

Next, create the following Kubernetes resources for our Aerospike destination cluster:

XDR destination database user login credentials, as a Kubernetes secret
Destination database cluster using our YAML file named ssd1_xdr_dest_6.1_cluster_cr.yaml

export secret_auth_name=xdr-user-auth-secret
export password_secret=admin123
kubectl -n aerospike create secret generic $secret_auth_name \
--from-literal=password=$password_secret
kubectl create -f ssd1_xdr_dest_6.1_cluster_cr.yaml
kubectl -n aerospike get po -w

You should see the database pods up and running successfully.

kubectl get po -n aerospike -w

aerocluster-dest-xdr-0-0   1/1     Running           0          24s

XDR-Proxy

Next, set up the xdr-proxy. Take a brief look at Fig. 1 Aerospike Kubernetes Operator, and you’ll notice that we are working from the right to the left in that order.

Configuration

Create the following xdr-proxy configuration file. Replace the seed address with a fully qualified domain name (FQDN) for the destination database pod(s) you created earlier. Multiple seed addresses may be added (hint: recommended in production).

cd ..
mkdir -p xdr-cfg/etc/auth
cd xdr-cfg/etc/

cat <<EOF> aerospike-xdr-proxy.yml
# Change the configuration for your use case.
# Naresh Maharaj
# Refer to https://www.aerospike.com/docs/connectors/enterprise/xdr-proxy/configuration/index.html

EOF

sudo tee auth/password_DC1.txt <<EOF

EOF
cd ..

kubectl -n aerospike create configmap xdr-proxy-cfg --from-file=etc/
kubectl -n aerospike create secret generic xdr-proxy-auth-secret \
--from-file=etc/auth

Deployment

Now that you have the xdr-proxy configuration file created, produce the Kubernetes deployment YAML file for the xdr-proxy. The following YAML file is used to deploy the xdr-proxy pods, ideally in the same data center or location where the destination databases will be hosted.

Tip: Remember that your xdr-proxy configuration differs from the Kubernetes xdr-proxy deployment file.

cat <<EOF> xdr-proxy-deployment.yaml

kubectl create -f ssd1_xdr_src_6.1_cluster_cr.yaml
kubectl get po -n aerospike -w

From the source cluster, confirm the XDR component has connected to the xdr-proxy by filtering the Kubernetes log file as shown in the following kubectl command.

kubectl -n aerospike logs aerocluster-source-xdr-0-0 -c aerospike-server | grep xdr | grep conn

Simple message test

Add some sample messages to the source database and confirm they are being received in the destination database cluster. Start by getting the source database service address and connect using Aerospike's command line tool - AQL.

kubectl get svc -n aerospike

NAME                         TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)             AGE

Insert a source record using the following command in AQL

kubectl run -it --rm --restart=Never aerospike-tool -n aerospike --image=aerospike/aerospike-tools:latest -- aql -U admin -P admin123 -h aerocluster-source-xdr-0-0

insert into test.a1 (PK,a,b,c,d) values(1,"A","B","C","D")
OK, 1 record affected.

aql> select * from test
+----+-----+-----+-----+-----+

+----+-----+-----+-----+-----+
| 1  | "A" | "B" | "C" | "D" |
+----+-----+-----+-----+-----+
1 row in set (0.023 secs)

Now, run the following select query in the destination cluster.

kubectl run -it --rm --restart=Never aerospike-tool -n aerospike --image=aerospike/aerospike-tools:latest -- aql -U admin -P admin123 -h aerocluster-dest-xdr-0-0

aql> select * from test

+----+-----+-----+-----+-----+
1 row in set (0.031 secs)

OK

Interim summary

At this point, it's confirmed that xdr-proxy is doing exactly what It should do.

If if you review the log file for the initial two xdr-proxies scheduled, you should see userKey=1.

kubectl logs xdr-proxy-7d9fccd6c8-5q7gn -n aerospike | grep record-parser
2022-12-08 14:53:50.607 GMT DEBUG record-parser - parsed message fields: key=Key(namespace='test', set=a1, digest=[120, 48, -23, -90, 110, 126, 84, -1, 114, -116, -9, -21, 28, 75, 126, -68, -51, 83, 31, -117], userKey=1, lastUpdateTimeMs=1670511230565, userKeyString=1, digestString='eDDppm5+VP9yjPfrHEt+vM1TH4s=')

kubectl logs xdr-proxy-7d9fccd6c8-f5zkt -n aerospike | grep \
record-parser
(none)

Scaling the XDR-Proxies

Go ahead and scale up the xdr-proxy to six pods by editing the file xdr-proxy-deployment.yaml and then apply the changes.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: xdr-proxy
  namespace: aerospike
  labels:
    app: xdr-proxy
spec:
  replicas: 6
  selector:
    matchLabels:
      app: xdr-proxy
...
kubectl apply -f xdr-proxy-deployment.yaml

You can achieve exactly the same by running the following command.

kubectl scale deploy xdr-proxy -n aerospike --replicas=6

You should now have six instances of the xdr-proxies running.

kubectl get po -n aerospike -w
NAME                         READY   STATUS    RESTARTS   AGE
aerocluster-dest-xdr-0-0     1/1     Running   0          3h50m

xdr-proxy-7d9fccd6c8-r56vs   1/1     Running   0          7s

Add some sample messages in the source cluster with primary keys 5, 6, and 7. Note that in Aerospike, a primary key serves as a unique identifier for a record within a specific set in a specific namespace. This key is a unique identifier for addressing the record for any operation.

aql> insert into test (PK,a,b) values (5,"A","B")
OK, 1 record affected.
aql> insert into test (PK,a,b) values (6,"A","B")
OK, 1 record affected.
aql> insert into test (PK,a,b) values (7,"A","B")
OK, 1 record affected.

Notice how userKey=5, userKey=6, and userKey=7 have been shipped across to the newly scaled xdr-proxies. Run the commands below to see the same,

However, we need to consider one critical factor. When data is actively flowing between source and destination clusters, the existing cached list of xdr-proxy connections from the source cluster will not be refreshed just because you added a bunch of new xdr-proxies. Consequently, the newly scaled xdr-proxies you have just scheduled will not be utilized immediately.

To demonstrate this, let's add data to the source cluster using Aerospike's benchmark tool. At the same time, we will scale the xdr-proxies on the destination side and observe the results.

Add data to the source cluster

Before you begin, reduce the xdr-proxy server count to one (1) to clarify the observations. In this example, I use my local machine, which has the benchmark tool installed, to send data to the source EC2 instances. To do this, you’ll need to obtain the external IP address of the source cluster’s Kubernetes service. You can download the benchmark tool from https://aerospike.com/docs/tools/install.

kubectl get AerospikeCluster aerocluster-source-xdr -n aerospike  -o yaml

You may need to add a firewall rule to allow traffic into the Kubernetes service. Connect the asbenchmark tool to start writing traffic using the public IP address for the NodePort Service.

asbenchmark -h 54.173.138.131:31999 -Uadmin -Padmin123 -z 10 -servicesAlternate -w RU,0 -o B256

Scale up the xdr-proxy servers from one to two and check the logs of both proxies to see what messages have been received. In a production environment, you should always disable the unnecessary logging.

Notice how no data has passed through the new xdr-proxy instance xdr-proxy-7d9fccd6c8-s2tzt.
