Add microk8s to pick-right-solution.md (#10542)
* Add microk8s to pick-right-solution.md
Microk8s is a single-command installation of upstream Kubernetes on any Linux and should be included in the list of local-machine solutions.

Add microk8s to foundational.md (#10543)
* 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?
* Rewrote first paragraph
And included a bullet list of features of microk8s

<h3>应用程序伸缩</h3>
|

|

<p>在之前的模块中，我们创建了一个 <a href="http://kubernetes.io/docs/user-guide/deployments/"> Deployment</a>，然后通过 <a href="http://kubernetes.io/docs/user-guide/services/">Service</a>让应用程序外部可见。
|
||
Deployment 仅为我们的应用程序创建了一个 Pod。
|
||
当流量增加时，我们将需要扩展应用程序以跟上用户需求。</p>

<p><b>Scaling</b> 是通过更改 Deployment 中的副本数量实现的。</p>

<p>扩展 Deployment 将确保创建新的 Pods 并将其调度到拥有可用资源的 Node 节点上，收缩会保证 Pods 数量减少至新的所需状态。
|
||
Kubernetes 还支持 Pods 的 <a href="http://kubernetes.io/docs/user-guide/horizontal-pod-autoscaling/"> 自动缩放 </a> ，但不在本教程范围之内。收缩到零也是可以的，此时它将终止指定 Deployment 的所有 Pod。 </p>
|
||
|
||
<p>运行应用程序的多个实例需要一种将流量分发给所有实例的方法。服务有内置的负载均衡器，可将网络流量分配给 Deployment 暴露的所有 Pods。服务通过使用 endpoints 持续监控运行的 Pods，以确保流量仅发送到可用的 Pods。</p>
