# ArangoDB Kubernetes Operator

[![Docker Pulls](https://img.shields.io/docker/pulls/arangodb/kube-arangodb.svg)](https://hub.docker.com/r/arangodb/kube-arangodb/)

ArangoDB Kubernetes Operator helps do run ArangoDB deployments
on Kubernetes clusters.

To get started, follow the Installation instructions below and/or
read the [tutorial](./docs/Manual/Tutorials/Kubernetes/README.md).

## State

The ArangoDB Kubernetes Operator is still in **development**.

Running ArangoDB deployments (single, active-failover or cluster)
is reasonably stable, and we're in the process of validating
production readiness of various Kubernetes platforms.

The feature set of the ArangoDB Kubernetes Operator is close to what
it is intended to be.

# `ArangoDeploymentReplication` resources.
helm install https://github.com/arangodb/kube-arangodb/releases/download/0.3.9/kube-arangodb.tgz
# To use `ArangoLocalStorage`, also run
helm install https://github.com/arangodb/kube-arangodb/releases/download/0.3.9/kube-arangodb-storage.tgz
```
