Introduction

Kubernetes ArangoDB Bootstrap Helper.

Chart Details

Chart will bootstrap ArangoDeployment with predefined Users, Databases, Collections and Permissions.

Prerequisites

ArangoDeployment as the destination. Bootstrap will ensure that ArangoDeployment is Ready before starting deployment

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
