Geode

A Chart to install Apache Geode clusters in kubernetes

Install Chart

To install the Geode in your Kubernetes cluster:

$ helm repo add geode-repo https://sbawaska.github.io/geode-helm-chart
"geode-repo" has been added to your repositories
$ helm install geode-repo/geode --name=my-geode-cluster

Dashboard

Follow the steps listed in the output of the above helm install command to launch Geode's dashboard (pulse)

Status

After installation succeeds, you can get a status of Chart

helm status <deployment name>

Tip: use helm list to get the deployment name

Delete

If you want to delete your Chart, use this command

helm delete <deployment name>

Install Chart with specific cluster size

By default, this Chart will create a geode cluster with one locator and 3 servers. If you want to change the cluster size during installation, you can use --set config.num_locators={value} to specify number of locators and --set config.num_servers={value} to specify the number of servers.

For example: To start 5 servers

helm install --set config.num_servers=5 incubator/geode

Install Chart with specific resource size

By default, this Chart creates a locator with 50m JVM heap and a server with 100m JVM heap. If you want to give more memory to your locator, you can use --set memory.max_locators={value} and for the servers --set memory.max_servers={value}.

For example: To start servers with 20G memory

helm install --set memory.max_servers=20g incubator/geode

Scale cluster

When you want to change the cluster size of your geode cluster, first lookup the name of the geode-server statefulset

kubectl get statefulsets

Then scale the stateful set using the kubectl scale command

kubectl scale statefulsets <deployment name>-geode-server --replicas=5
