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 defaultArangoDeploymentReplications- enabled by defaultArangoLocalStorage- disabled by defaultArangoBackup- disabled by defaultArangoJob- disabled by defaultArangoClusterSynchronization- 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
