⁠Zundoko Operator

Zundoko Operator is a Kubernetes operator⁠ built with Kubebuilder⁠, that plays ZundokoKiyoshi.

⁠Deploy to Kubernetes cluster

You need kubectl⁠ 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.)

   apiVersion: zundokokiyoshi.kaitoy.github.com/v1beta1
   kind: Hikawa
   metadata:
     labels:
       controller-tools.k8s.io: "1.0"
     name: hikawa-sample
   spec:
     intervalMillis: 500
   

   Copy

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

   [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
   

   Copy

4. See Kiyoshi by: kubectl get kiyoshi

   [root@k8s-master ~]# kubectl get kiyoshi
   NAME                    SAY        AGE
   hikawa-sample-kiyoshi   Kiyoshi!   7m
   

   Copy

5. Delete the manifest to clean a ZundokoKiyoshi.
