Zundoko Operator
=========================
Zundoko Operator is a [Kubernetes operator](https://github.com/operator-framework/awesome-operators) built with [Kubebuilder](https://github.com/kubernetes-sigs/kubebuilder), that plays ZundokoKiyoshi.
Deploy to Kubernetes cluster
-----------------------------------
You need [kubectl](https://kubernetes.io/docs/reference/kubectl/overview/) to deploy Zundoko Operator with it.
1. `git clone https://github.com/kaitoy/zundoko-operator.git`
2. `cd zundoko-operator`
3. `kubectl apply -f config/crds/zundokokiyoshi_v1beta1_hikawa.yaml`
4. `kubectl apply -f config/crds/zundokokiyoshi_v1beta1_kiyoshi.yaml`
5. `kubectl apply -f config/crds/zundokokiyoshi_v1beta1_zundoko.yaml`
6. `kubectl apply -f zundoko-operator.yaml`
Usage
-----
### Start a ZundokoKiyoshi
1. Write a Hikawa manifest.
e.g.)
```yaml
apiVersion: zundokokiyoshi.kaitoy.github.com/v1beta1
kind: Hikawa
metadata:
labels:
controller-tools.k8s.io: "1.0"
name: hikawa-sample
spec:
intervalMillis: 500
```
2. Apply the manifest to start a ZundokoKiyoshi.
* Zundoko Operator starts to create Zundokos one by one with the Say fields set to "Zun" or "Doko" randomly.
* When 4 "Zun"s are created and then "Doko" is done, Zundoko Operator creates Kiyoshi.
3. See Zundokos by: `kubectl get zundoko`
```sh
[root@k8s-master ~]# kubectl get zundoko
NAME SAY AGE
hikawa-sample-zundoko-001 Doko 6m
hikawa-sample-zundoko-002 Doko 6m
hikawa-sample-zundoko-003 Doko 6m
hikawa-sample-zundoko-004 Zun 6m
hikawa-sample-zundoko-005 Doko 6m
hikawa-sample-zundoko-006 Doko 6m
```
4. See Kiyoshi by: `kubectl get kiyoshi`
```sh
[root@k8s-master ~]# kubectl get kiyoshi
NAME SAY AGE
hikawa-sample-kiyoshi Kiyoshi! 7m
```
5. Delete the manifest to clean a ZundokoKiyoshi.
Development
-----------
You need [Docker](https://www.docker.com/) to build Zundoko Operator container image, and [kustomize](https://github.com/kubernetes-sigs/kustomize) to generate a Kubernetes manifest file.
1. Build container image
1. `git clone https://github.com/kaitoy/zundoko-operator.git`
2. `cd zundoko-operator`
3. `docker build .`
2. Generate Kubernetes manifest file
1. `kustomize build config/default > zundoko-operator.yaml`
