Aerospike Helm Chart

This is an implementation of Aerospike StatefulSet found here:

• https://github.com/aerospike/aerospike-kubernetes

Pre Requisites

• Kubernetes 1.7+ with beta APIs enabled and support for statefulsets

• PV support on underlying infrastructure (only if you are provisioning persistent volume).

• Requires at least v2.5.0 version of helm to support

Chart Details

This chart will do the following:

• Implement a dynamically scalable Aerospike cluster using Kubernetes StatefulSets

Installing the Chart

To install the chart with the release name my-aerospike using a dedicated namespace(recommended):

helm repo add incubator http://storage.googleapis.com/kubernetes-charts-incubator
helm install --name my-aerospike --namespace aerospike stable/aerospike

The chart can be customized using the following configurable parameters:

Parameter	Description	Default
image.repository	Aerospike Container image name	aerospike/aerospike-server
image.tag	Aerospike Container image tag	4.5.0.5
image.pullPolicy	Aerospike Container pull policy	Always
replicaCount	Aerospike Brokers	1
command	Custom command (Docker Entrypoint)	[]
args	Custom args (Docker Cmd)	[]
persistentVolume	Config of persistent volumes for storage-engine	{}
confFile	Config filename. This file should be included in the chart path	aerospike.conf
resources	Resource requests and limits	{}
nodeSelector	Labels for pod assignment	{}
terminationGracePeriodSeconds	Wait time before forcefully terminating container	30

Specify parameters using --set key=value[,key=value] argument to helm install

Alternatively a YAML file that specifies the values for the parameters can be provided like this:

helm install --name my-aerospike -f values.yaml stable/aerospike

Conf files for Aerospike

There is one conf file added to each Aerospike release. This conf file can be replaced with a custom file and updating the confFile value.

If you modify the aerospike.conf (and you use more than 1 replica), you want to add the #REPLACE_THIS_LINE_WITH_MESH_CONFIG comment to the config file (see the default conf file). This will update your mesh to connect each replica.

Known Limitations

• Persistent volume claims tested only on GCP
• Aerospike cluster is not accessible via an external endpoint
