ArangoDB Kubernetes Operator
The ArangoDB Kubernetes Operator (kube-arangodb) is a set of operators
that you deploy in your Kubernetes cluster to:
- Manage deployments of the ArangoDB database
- Manage backups
- Provide
PersistentVolumeson local storage of your nodes for optimal storage performance. - Configure ArangoDB Datacenter-to-Datacenter Replication
Each of these uses involves a different custom resource:
- Use an ArangoDeployment resource to create an ArangoDB database deployment.
- Use an ArangoMember resource to observe and adjust individual deployment members.
- Use an ArangoBackup and ArangoBackupPolicy resources to create ArangoDB backups.
- Use an ArangoLocalStorage resource to provide local
PersistentVolumesfor optimal I/O performance. - Use an ArangoDeploymentReplication resource to configure ArangoDB Datacenter-to-Datacenter Replication.
Continue with Using the ArangoDB Kubernetes Operator to learn how to install the ArangoDB Kubernetes operator and create your first deployment.
State
The ArangoDB Kubernetes Operator is Production ready.
Limits
| Limit | Description | Community | Enterprise |
|---|---|---|---|
| Cluster size limit | Limits of the nodes (DBServers & Coordinators) supported in the Cluster mode | 64 | 1024 |
Production readiness state
Beginning with Version 0.3.11 we maintain a production readiness state for individual new features, since we expect that new features will first be released with an "alpha" or "beta" readiness state and over time move to full "production readiness".
Operator will support Kubernetes versions supported on providers and maintained by Kubernetes. Once version is not supported anymore it will go into "Deprecating" state and will be marked as deprecated on Minor release.
Kubernetes versions starting from 1.18 are supported and tested, charts and manifests can use API Versions which are not present in older versions.
The following table has the general readiness state, the table below covers individual newer features separately.
| Platform | Kubernetes Version | ArangoDB Version | State | Remarks | Provider Remarks |
|---|---|---|---|---|---|

- Community Edition:
arangodb/kube-arangodb:1.2.41 - Enterprise Edition:

Installation of latest release using Kubectl
This procedure can also be used for upgrades and will not harm any running ArangoDB deployments.

Installation of latest release using kustomize
Installation using kustomize looks like installation from yaml files, but user is allowed to modify namespace or resource names without yaml modifications.
It is recommended to use kustomization instead of handcrafting namespace in yaml files - kustomization will replace not only resource namespaces, but also namespace references in resources like ClusterRoleBinding.
See manifests/kustomize directory for available combinations of installed features.
Community Edition example

kind: Kustomization
namespace: my-custom-namespace
resources:
- https://github.com/arangodb/kube-arangodb/manifests/kustomize/crd?ref=1.2.36
- https://github.com/arangodb/kube-arangodb/manifests/kustomize/deployment?ref=1.2.36
Enterprise Edition example
apiVersion: kustomize.config.k8s.io/v1beta1

namespace: my-custom-namespace

Installation of latest release using Helm
Only use this procedure for clean installation of the operator. For upgrades see next section
Community Edition
# The following will install the operator and basic CRDs resources.
helm install --generate-name https://github.com/arangodb/kube-arangodb/releases/download/1.2.41/kube-arangodb-1.2.41.tgz
# To use `ArangoLocalStorage`, set field `operator.features.storage` to true
helm install --generate-name https://github.com/arangodb/kube-arangodb/releases/download/1.2.41/kube-arangodb-1.2.41.tgz --set "operator.features.storage=true"
Enterprise Edition
# The following will install the operator and basic CRDs resources.
helm install --generate-name https://github.com/arangodb/kube-arangodb/releases/download/1.2.41/kube-arangodb-1.2.41.tgz --set "operator.image=arangodb/kube-arangodb-enterprise:1.2.41"
# To use `ArangoLocalStorage`, set field `operator.features.storage` to true
helm install --generate-name https://github.com/arangodb/kube-arangodb/releases/download/1.2.41/kube-arangodb-1.2.41.tgz --set "operator.image=arangodb/kube-arangodb-enterprise:1.2.41" --set "operator.features.storage=true"
Upgrading the operator using Helm
To upgrade the operator to the latest version with Helm, you have to delete the previous operator deployment and then install the latest. HOWEVER: You must not delete the custom resource definitions (CRDs), or your ArangoDB deployments will be deleted!
Therefore, you have to use helm list to find the deployments for the
operator (kube-arangodb) and use helm delete to delete them using the
automatically generated deployment names. Here is an example of a helm list output:
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
kube-arangodb-1-1696919877 default 1 2023-10-10 08:37:57.884783199 +0200 CEST deployed kube-arangodb-1.2.31
So here, you would have to do
helm delete kube-arangodb-1-1696919877
Then you can install the new version with helm install as normal:
