Quick Start
$ 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:
$ 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:
$ 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,
$ 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,
$ helm install --name my-release -f values.yaml stable/terracotta
Tip: You can use the default values.yaml
