* Add microk8s to foundational.md
Adding microk8s as credible and stable alternative to get started with Kubernetes on a local machine. This is especially attractive for those not wanting to incur the overhead of running a VM for a local cluster.
* Update foundational.md
Thank you for your suggestions! LMK if this works now?

此任务展示如何调试StatefulSet。
{{% /capture %}}
{{% capture prerequisites %}}
- 你需要有一个Kubernetes集群,通过必要的配置使kubectl命令行工具与您的集群进行通信。
- 你应该有一个运行中的StatefulSet,以便用于调试。

调试StatefulSet
由于StatefulSet在创建时设置了app=myapp标签,列出仅属于该StatefulSet的所有pod时,可以使用以下命令:
kubectl get pods -l app=myapp
如果您发现列出的任何Pods长时间处于Unknown 或Terminating状态,关于如何处理它们的说明任务,请参阅删除 StatefulSet Pods。您可以参考调试 Pods指南来调试StatefulSet中的各个Pod。
StatefulSets提供调试机制,可以使用注解来暂停所有控制器在Pod上的操作。在任何StatefulSet Pod上设置pod.alpha.kubernetes.io/initialized注解为"false"将暂停 StatefulSet的所有操作。暂停时,StatefulSet将不执行任何伸缩操作。一旦调试钩子设置完成后,就可以在StatefulSet pod的容器内执行命令,而不会造成伸缩操作的干扰。您可以通过执行以下命令将注解设置为"false":
kubectl annotate pods <pod-name> pod.alpha.kubernetes.io/initialized="false" --overwrite
当注解设置为"false"时,StatefulSet在其Pods变得不健康或不可用时将不会响应。StatefulSet不会创建副本Pod直到每个Pod上删除注解或将注解设置为"true"。
逐步初始化
创建StatefulSet之前,您可以通过使用和上文相同的注解,即将yaml文件中.spec.template.metadata.annotations里的pod.alpha.kubernetes.io/initialized字段设置为"false",对竞态条件的StatefulSet进行调试。
apiVersion: apps/v1beta1
kind: StatefulSet
metadata:
name: my-app
spec:
serviceName: "my-app"
replicas: 3
template:
metadata:
labels:
app: my-app
annotations:
pod.alpha.kubernetes.io/initialized: "false"
...
...
...
设置注解后,如果创建了StatefulSet,您可以等待每个Pod来验证它是否正确初始化。StatefulSet将不会创建任何后续的Pods,直到在已经创建的每个Pod上将调试注解设置为"true" (或删除)。 您可以通过执行以下命令将注解设置为"true":
kubectl annotate pods <pod-name> pod.alpha.kubernetes.io/initialized="true" --overwrite
