For optimal performance, ArangoDB should be configured with locally attached
SSD storage.
To accomplish this, one must create `PersistentVolumes` for all servers that
The easiest way to accomplish this is to deploy an
[`ArangoLocalStorage` resource](./StorageResource.md).
The ArangoDB Storage Operator will use it to provide `PersistentVolumes` for you.
The alternative is to create `PersistentVolumes` manually, for all servers that
need persistent storage (single, agents & dbservers).
E.g. for a `Cluster` with 3 agents and 5 dbservers, you must create 8 volumes.

## Installation
The ArangoDB Kubernetes Operator needs to be installed in your Kubernetes
cluster first. To do so, clone this repository and run:
cluster first.
To do so, run (replace `<version>` with the version of the operator that you want to install):
```bash
kubectl apply -f manifests/crd.yaml
kubectl apply -f manifests/arango-deployment.yaml
kubectl apply -f https://raw.githubusercontent.com/arangodb/kube-arangodb/<version>/manifests/crd.yaml
kubectl apply -f https://raw.githubusercontent.com/arangodb/kube-arangodb/<version>/manifests/arango-deployment.yaml
```
To use `ArangoLocalStorage`, also run:
```bash
kubectl apply -f manifests/arango-storage.yaml
kubectl apply -f https://raw.githubusercontent.com/arangodb/kube-arangodb/<version>/manifests/arango-storage.yaml
```
You can find the latest release of the ArangoDB Kubernetes Operator
[in the kube-arangodb repository](https://github.com/arangodb/kube-arangodb/releases/latest).
## Cluster creation
Once the operator is running, you can create your ArangoDB cluster
by creating a custom resource and deploying it.
For example:
For example (all examples can be found [in the kube-arangodb repository](https://github.com/arangodb/kube-arangodb/tree/master/examples)):
```bash
kubectl apply -f examples/simple-cluster.yaml

The second command installs a `Deployment` that runs the operator that controls

The optional third command installs a `Deployment` that runs the operator that
provides `PersistentVolumes` on local disks of the cluster nodes.
Use this when running on bare-metal or if there is no provisioner for fast
storage in your Kubernetes cluster.

The first database we are going to deploy is a single server database.
