Tarantool

Tarantool Tarantool is a Lua application server integrated with a database management system.

Introduction

This chart bootstraps a Tarantool deployment on a Kubernetes cluster using the Helm package manager.

The chart is heavily based on stable/redis chart.

Configuration

The following tables lists the configurable parameters of the Tarantool chart and their default values.

Parameter	Description	Default
image	Tarantool image	tarantool/tarantool:1.8
imagePullPolicy	Image pull policy	IfNotPresent
serviceType	Kubernetes Service type	ClusterIP
useSecurity	Use password	false
tarantoolUser	Tarantool username	tarantool
tarantoolPassword	Tarantool password	Randomly generated
args	Tarantool command-line args	[]
persistence.enabled	Use a PVC to persist data	true
persistence.existingClaim	Use an existing PVC to persist data	nil
persistence.storageClass	Storage class of backing PVC	generic
persistence.accessMode	Use volume as ReadOnly or ReadWrite	ReadWriteOnce
persistence.size	Size of data volume	8Gi
resources	CPU/Memory resource requests/limits	Memory: 256Mi, CPU: 100m
nodeSelector	Node labels for pod assignment	{}
tolerations	Toleration labels for pod assignment	[]
networkPolicy.enabled	Enable NetworkPolicy	false
networkPolicy.allowExternal	Don't require client label for connections	true
service.annotations	annotations for tarantool service	{}
service.loadBalancerIP	loadBalancerIP if service type is LoadBalancer	``

The above parameters map to the env variables defined in tarantool/tarantool. For more information please refer to the tarantool/tarantool image documentation.

Persistence

The Tarantool image stores the Tarantool data at the /var/lib/tarantool path of the container.

By default, the chart mounts a Persistent Volume volume at this location. The volume is created using dynamic volume provisioning. If a Persistent Volume Claim already exists, specify it during installation.

Existing PersistentVolumeClaim

1. Create the PersistentVolume
2. Create the PersistentVolumeClaim
3. Install the chart

$ helm install --set persistence.existingClaim=PVC_NAME tarantool
