Redis Labs helm repository

Deprecation Notice

This repository is deprecated and should not be used, to deploy Redis Enterprise on Kubernetes pelease refer to the Redis Enterprise Operator: https://github.com/RedisLabs/redis-enterprise-k8s-docs

Redis Enterprise Chart

To install the chart just run:

helm install --namespace redis -n 'redis-enterprise' ./redis-enterprise

To install the chart with an override file:

helm install --namespace redis -n 'redis-enterprise' ./redis-enterprise -f ./redis-enterprise/values.yaml -f ./override-values.yaml

GKE quickstart

password=$(gcloud container clusters describe YOUR_SETUP_NAME --zone us-central1-a | grep password | cut -d":" -f 2 | tr -d " ")
kubectl --username=admin --password=$password apply -f rbac_tiller.yaml
helm init --service-account tiller
helm install --namespace redis -n 'prod' ./redis-enterprise

Generate static files

To generate static yaml files from the chart file you can run the following command (note the output dir should exists before running this):

helm template --namespace redis -n 'prod' ./redis-enterprise -f ./redis-enterprise/values.yaml -f ./override.yaml --output-dir /tmp/helm_out

override files are not mandatory, its only needed if one would like to override the defaults values.

   requests:
    cpu: 2
    memory: 4096Mi
