• Operator3-设计一个operator二-owns的使用

    背景：

    上一节（Operator3-设计一个operator）做完发现一个问题 我创建了jan 应用jan-sample，子资源包括deployment，service.ingress,pod(其中pod是deployment管理的)
    image.png
    手动删除Pod.由于Deployment rc控制器。Pod资源可以自动重建。但是我删除deployment能不能自动重建呢？正常的deployment service ingress子资源的生命周期，我应该是靠jan应用去维系的，试一试：

    [zhangpeng@zhangpeng jan]$ kubectl delete deployment jan-sample
deployment.apps "jan-sample" deleted
[zhangpeng@zhangpeng jan]$ kubectl get deployment
No resources found in default namespace.

    到这里才发现没有考虑周全…删除deployment资源并不能重建，正常创建应用应该要考虑一下jan资源下面资源的重建.搜了一下别人写的operator貌似的可以加一下Owns，尝试一下！

    Deployment Ingress Service关于Owns的使用

    Deployment

    func (r *JanReconciler) SetupWithManager(mgr ctrl.Manager) error {
	return ctrl.NewControllerManagedBy(mgr).
		For(&janv1.Jan{}).
		Owns(&appsv1.Deployment{}).
		Complete(r)
}

    Deployment delete尝试

    make run develop-operator项目，并尝试delete deployment jan-sample查看是否重建：

    [zhangpeng@zhangpeng develop-operator]$ kubectl get Jan
[zhangpeng@zhangpeng develop-operator]$ kubectl get all

    [zhangpeng@zhangpeng develop-operator]$ kubectl delete deployment jan-sample
[zhangpeng@zhangpeng develop-operator]$ kubectl get deployment

    • 2

    image.png
    恩发现deployment应用可以自动重建了！

    image.png

    Ingress and Service资源

    简单添加一下Owns？

    but其他资源是否可以呢？是不是也偷懒一下添加Owns？

    func (r *JanReconciler) SetupWithManager(mgr ctrl.Manager) error {
	return ctrl.NewControllerManagedBy(mgr).
		For(&janv1.Jan{}).
		Owns(&appsv1.Deployment{}).
		Owns(&corev1.Service{}).
		Owns(&v1.Ingress{}).
		Complete(r)
}

    尝试了一下不生效的，但是这种方式思路是对的至于为什么不生效呢？
    deploy声明了&appv1.Deployment,但是service,ingress是没有创建变量声明的！

    拆分改造代码

    继续改造Jan operator使其支持service ingress子资源的误删除创建：

    把这边拆分一下？

    [zhangpeng@zhangpeng develop-operator]$ kubectl delete svc jan-sample
[zhangpeng@zhangpeng develop-operator]$ kubectl get svc

    en service的自动恢复生效了
    image.png
    然后试一试ingress

    [zhangpeng@zhangpeng develop-operator]$ kubectl get ingress
[zhangpeng@zhangpeng develop-operator]$ kubectl delete ingress jan-sample
[zhangpeng@zhangpeng develop-operator]$ kubectl get ingress

    继续发现问题:
    en,我修改一下jan_v1_jan.yaml中host ww1.zhangpeng.com修改为ww11.zhangpeng.com,but ingress的相关信息没有及时更新啊？
    image.png
    继续模仿一下上面的service oldservice newservice新增 newIngress oldIngress ：
    image.png
    重新make run
    ingress相关信息得到了修改

    2. 将 deployment service ingress或者其他资源作为operator应用的子资源，进行生命周期管理
    3. 下一步想处理一下 make run 控制台的输出，输出一些有用的信息
