DEPRECATION NOTICE

This chart is deprecated and no longer supported.

Quick Start

bash

$ helm install stable/terracotta

Introduction

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

Prerequisites

Kubernetes 1.10+

Installing the Chart

To install the chart with the release name my-release:

bash

$ helm install --name my-release stable/terracotta

The command deploys Terracotta on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Tip: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

bash

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Configuration

The following table lists the configurable parameters of the Terracotta chart and their default values.

Parameter	Description	Default
`image.repository`	Terracotta Image name	`terracotta/terracotta-server-oss`
`image.tag`	Terracotta Image tag	`{VERSION}`
`image.pullPolicy`	Image pull policy	`Always`
`replicaCount`	Number of Terracotta members	2
`offheaps`	Offheap resource defintions, as a list of {name, size, unit}	`[{offheap-1, 512, MB}, {offheap-2, 256, MB}]`
`nodeSelector`	Terracotta Node labels for pod assignment	`nil`
`resources`	CPU/Memory resource requests/limits	`nil`
`service.type`	Kubernetes service type ('ClusterIP', 'LoadBalancer', or 'NodePort')	`ClusterIP`
`service.clusterIP`	Kubernetes service ClusterIP	`None`
`service.terracottaPort`	Kubernetes main service port	`9410`
`service.syncPort`	Kubernetes sync service port	`9430`

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

bash

$ helm install --name my-release \
  --set replicaCount=3  --set offheaps[0].name=otherOffheap --set offheaps[0].unit=GB --set offheaps[0].size=6 \
    stable/terracotta

The above command sets number of Terracotta nodes to 3, and it defines just 1 offheap resource named otherOffheap, 6 GB large

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

bash

$ helm install --name my-release -f values.yaml stable/terracotta

Tip: You can use the default values.yaml
