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 PersistentVolumes on 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 PersistentVolumes for 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.

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.

Installation and Usage

Docker images:

• Community Edition: arangodb/kube-arangodb:1.2.43
• Enterprise Edition: arangodb/kube-arangodb-enterprise:1.2.43

Installation of latest release using Kubectl

This procedure can also be used for upgrades and will not harm any running ArangoDB deployments.

Community Edition

kubectl apply -f https://raw.githubusercontent.com/arangodb/kube-arangodb/1.2.43/manifests/arango-crd.yaml
kubectl apply -f https://raw.githubusercontent.com/arangodb/kube-arangodb/1.2.43/manifests/arango-deployment.yaml
# To use `ArangoLocalStorage`, also run
kubectl apply -f https://raw.githubusercontent.com/arangodb/kube-arangodb/1.2.43/manifests/arango-storage.yaml
# To use `ArangoDeploymentReplication`, also run
kubectl apply -f https://raw.githubusercontent.com/arangodb/kube-arangodb/1.2.43/manifests/arango-deployment-replication.yaml

Enterprise Edition

kubectl apply -f https://raw.githubusercontent.com/arangodb/kube-arangodb/1.2.43/manifests/enterprise-crd.yaml
kubectl apply -f https://raw.githubusercontent.com/arangodb/kube-arangodb/1.2.43/manifests/enterprise-deployment.yaml
# To use `ArangoLocalStorage`, also run
kubectl apply -f https://raw.githubusercontent.com/arangodb/kube-arangodb/1.2.43/manifests/enterprise-storage.yaml
# To use `ArangoDeploymentReplication`, also run
kubectl apply -f https://raw.githubusercontent.com/arangodb/kube-arangodb/1.2.43/manifests/enterprise-deployment-replication.yaml

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

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
namespace: my-custom-namespace
resources:
  - https://github.com/arangodb/kube-arangodb/manifests/kustomize/crd?ref=1.2.43
  - https://github.com/arangodb/kube-arangodb/manifests/kustomize/deployment?ref=1.2.43

Enterprise Edition example

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
namespace: my-custom-namespace
resources:
  - https://github.com/arangodb/kube-arangodb/manifests/kustomize-enterprise/crd?ref=1.2.43
  - https://github.com/arangodb/kube-arangodb/manifests/kustomize-enterprise/deployment?ref=1.2.43

Installation of latest release using Helm

Only use this procedure for clean installation of the operator. For upgrades see next section

From Chart Repository

Chart Installation

# Add helm repository
helm repo add kube-arangodb https://arangodb.github.io/kube-arangodb

Community Edition

# The following will install the operator and basic CRDs resources.
helm install --generate-name kube-arangodb/kube-arangodb
# To use `ArangoLocalStorage`, set field `operator.features.storage` to true
helm install --generate-name kube-arangodb/kube-arangodb --set "operator.features.storage=true"

Enterprise Edition

helm install --generate-name kube-arangodb/kube-arangodb-enterprise
# To use `ArangoLocalStorage`, set field `operator.features.storage` to true
helm install --generate-name kube-arangodb/kube-arangodb-enterprise --set "operator.features.storage=true"

From Chart Release

Community Edition

# The following will install the operator and basic CRDs resources.
helm install --generate-name https://github.com/arangodb/kube-arangodb/releases/download/1.2.43/kube-arangodb-1.2.43.tgz
# To use `ArangoLocalStorage`, set field `operator.features.storage` to true
helm install --generate-name https://github.com/arangodb/kube-arangodb/releases/download/1.2.43/kube-arangodb-1.2.43.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/1.2.43/kube-arangodb-enterprise-1.2.43.tgz
# To use `ArangoLocalStorage`, set field `operator.features.storage` to true
helm install --generate-name https://github.com/arangodb/kube-arangodb/releases/download/1.2.43/kube-arangodb-enterprise-1.2.43.tgz --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:

Community Edition

# The following will install the operator and basic CRDs resources.
helm install --generate-name https://github.com/arangodb/kube-arangodb/releases/download/1.2.43/kube-arangodb-1.2.43.tgz
# To use `ArangoLocalStorage`, set field `operator.features.storage` to true
helm install --generate-name https://github.com/arangodb/kube-arangodb/releases/download/1.2.43/kube-arangodb-1.2.43.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/1.2.43/kube-arangodb-enterprise-1.2.43.tgz
# To use `ArangoLocalStorage`, set field `operator.features.storage` to true
helm install --generate-name https://github.com/arangodb/kube-arangodb/releases/download/1.2.43/kube-arangodb-enterprise-1.2.43.tgz --set "operator.features.storage=true"
