+# Start ArangoDB on Kubernetes in 5min
+
+Starting an ArangoDB database (either single server or full blown cluster)
+on Kubernetes involves a lot of resources.
+
+The servers needs to run in `Pods`, you need `Secrets` for authentication,
+TLS certificates and `Services` to enable communication with the database.
+
+Use `kube-arangodb`, the ArangoDB Kubernetes operator to greatly simplify
+this process.
+
+In this guide, we'll explain what the ArangoDB Kubernetes operator is,
+how to install it and how use it to deploy your first ArangoDB database
+in a Kubernetes cluster.
+
+## What is `kube-arangodb`
+
+`kube-arangodb` is a set of two operators that you deploy in your Kubernetes
+cluster to (1) manage deployments of the ArangoDB database and (2)
+provide `PersistenVolumes` on local storage of your nodes for optimal
+storage performace.
+
+Note that the operator that provides `PersistentVolumes` is not needed to
+run ArangoDB deployments. You can also use `PersistentVolumes` provided
+by other controllers.
+
+In this guide we'll focus on the `ArangoDeployment` operator.
+
+## Installing `kube-arangodb`
+
+To install `kube-arangodb` in your Kubernetes cluster, make sure
+you have acces to this cluster and the rights to deploy resources
+at cluster level.
+
+For now, any recent Kubernetes cluster will do (e.g. `minikube`).
+
+Then run (replace `<version>` with the version of the operator that you want to install):
+
+```bash
+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
+```
+
+The first command installs two `CustomResourceDefinitions` in your Kubernetes cluster:
+
+- `ArangoDeployment` is the resource used to deploy ArangoDB database.
+- `ArangoLocalStorage` is the resource used to provision `PersistentVolumes` on local storage.
+
+The second command installs a `Deployment` that runs the operator that controls
+`ArangoDeployment` resources.
+
+## Deploying your first ArangoDB database
+
+The first database we're going to deploy is a single server database.
+
+Create a file called `single-server.yaml` with the following content.
+
+```yaml
+apiVersion: "database.arangodb.com/v1alpha"
+kind: "ArangoDeployment"
+metadata:
+  name: "single-server"
+spec:
+  mode: single
+```
+
+Now insert this resource in your Kubernetes cluster using:
+
+```bash
+kubectl apply -f single-server.yaml
+```
+
+The `ArangoDeployment` operator in `kube-arangodb` will now inspect the
+resource you just deployed and start the process to run a single server database.
+
+To inspect the currentl status of your deployment, run:
+
+```bash
+kubectl describe ArangoDeployment single-server
+# or shorter
+kubectl describe arango single-server
+```
+
+To inspect the pods created for this deployment, run:
+
+```bash
+kubectl get pods --selector=arango_deployment=single-server
+```
+
+The result will look similar to this:
+
+```plain
+NAME                                 READY     STATUS    RESTARTS   AGE
+single-server-sngl-cjtdxrgl-fe06f0   1/1       Running   0          1m
+```
+
+Once the pod reports that it is has a `Running` status and is ready,
+your database s available.
+
+## Connecting to your database
+
+The single server database you deployed in the previous chapter is now
+available, but only from within the Kubernetes cluster.
+
+To make the database available outside your Kubernetes cluster (e.g. for browser acces)
+you must deploy an additional `Service`.
+
+There are several possible types of `Service` to choose from.
+We're going to use the `NodePort` type to expose the database on port 30529 of
+every node of your Kubernetes cluster.
+
+Create a file called `single-server-service.yaml` with the following content.
+
+```yaml
+kind: Service
+apiVersion: v1
+metadata:
+  name: single-server-service
+spec:
+  selector:
+    app: arangodb
+    arango_deployment: single-server
+    role: single
+  type: NodePort
+  ports:
+  - protocol: TCP
+    port: 8529
+    targetPort: 8529
+    nodePort: 30529
+```
+
+Deploy the `Service` into your Kubernetes cluster using:
+
+```bash
+kubectl apply -f single-server-service.yaml
+```
+
+Now you can connect your browser to `https://<node name>:30529/`,
+where `<node name>` is the name or IP address of any of the nodes
+of your Kubernetes cluster.
+
+Your browser will show a warning about an unknown certificate.
+Accept the certificate for now.
+
+Then login using username `root` and an empty password.
+
+If you want to delete your single server ArangoDB database, just run:
+
+```bash
+kubectl delete ArangoDeployment single-server
+```
+
+## Deploying a full blown ArangoDB cluster database
+
+The deployment of a full blown cluster is very similar to deploying
+a single server database. The difference is in the `mode` field of
+the `ArangoDeployment` specification.
+
+Create a file called `cluster.yaml` with the following content.
+
+```yaml
+apiVersion: "database.arangodb.com/v1alpha"
+kind: "ArangoDeployment"
+metadata:
+  name: "cluster"
+spec:
+  mode: cluster
+```
+
+Now insert this resource in your Kubernetes cluster using:
+
+```bash
+kubectl apply -f cluster.yaml
+```
+
+The same commands used in the single server deployment can be used
+to inspect your cluster. Just use the correct deployment name (`cluster` instead of `single-server`).
+
+Connecting to your cluster requires a different `Service` since the
+selector now has to select your `cluster` deployment and instead
+of selecting all `Pods` with role `single` it will have to select
+all coordinator pods.
+
+The service looks like this:
+
+```yaml
+kind: Service
+apiVersion: v1
+metadata:
+  name: cluster-service
+spec:
+  selector:
+    app: arangodb
+    arango_deployment: cluster
+    role: coordinator
+  type: NodePort
+  ports:
+  - protocol: TCP
+    port: 8529
+    targetPort: 8529
+    nodePort: 31529
+```
+
+Note that we've choosen a different node port (31529) for this `Service`
+to avoid conflicts with the port used in `single-server-service`.
