Introduction

Kubernetes ArangoDB Operator.

Chart Details

Chart will install fully operational ArangoDB Kubernetes Operator.

Resources Required

In default installation deployment with 1 pod will be created. The operator pod require 256MB of ram and 250m of CPU.

Installing the Chart

Chart can be installed in two methods:

• With all Operators in single Helm Release
• One Helm Release per Operator

Possible Operators:

• ArangoDeployment - enabled by default
• ArangoDeploymentReplications - enabled by default
• ArangoLocalStorage - disabled by default
• ArangoBackup - disabled by default
• ArangoJob - disabled by default
• ArangoClusterSynchronization - disabled by default

To install Operators in mode "One per Helm Release" we can use:

helm install --name arango-deployment kube-arangodb.tar.gz \
             --set operator.features.deployment=true \
             --set operator.features.deploymentReplications=false \
             --set operator.features.storage=false \
             --set operator.features.backup=false \
             --set operator.features.apps=false \
             --set operator.features.k8sToK8sClusterSync=false
