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.
* capitalized Istio
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

证书轮换 | templates/task |
{{% capture overview %}} 本文展示如何在 kubelet 中启用并配置证书轮换。 {{% /capture %}}
{{% capture prerequisites %}}
-
要求 Kubernetes 1.8.0 或更高的版本
-
Kubelet 证书轮换在 1.8.0 版本中处于 beta 阶段, 这意味着该特性可能在没有通知的情况下发生变化。
{{% /capture %}}
{{% capture steps %}}
概述
Kubelet 使用证书进行 Kubernetes API 的认证。 默认情况下，这些证书的签发期限为一年，所以不需要太频繁地进行更新。
Kubernetes 1.8 版本中包含 beta 特性 kubelet 证书轮换， 在当前证书即将过期时， 将自动生成新的秘钥，并从 Kubernetes API 申请新的证书。 一旦新的证书可用，它将被用于与 Kubernetes API 间的连接认证。
启用客户端证书轮换
kubelet 进程接收 --rotate-certificates 参数，该参数决定 kubelet 在当前使用的证书即将到期时，
是否会自动申请新的证书。 由于证书轮换是 beta 特性，必须通过参数 --feature-gates=RotateKubeletClientCertificate=true 进行启用。
kube-controller-manager 进程接收
--experimental-cluster-signing-duration 参数，该参数控制证书签发的有效期限。
理解证书轮换配置
当 kubelet 启动时，如被配置为自举（使用--bootstrap-kubeconfig 参数），kubelet 会使用其初始证书连接到
Kubernetes API ，并发送证书签名的请求。 可以通过以下方式查看证书签名请求的状态：
kubectl get csr
最初，来自节点上 kubelet 的证书签名请求处于 Pending 状态。 如果证书签名请求满足特定条件，
控制器管理器会自动批准，此时请求会处于 Approved 状态。 接下来，控制器管理器会签署证书，
证书的有效期限由 --experimental-cluster-signing-duration 参数指定，签署的证书会被附加到证书签名请求中。
Kubelet 会从 Kubernetes API 取回签署的证书，并将其写入磁盘，存储位置通过 --cert-dir 参数指定。
然后 kubelet 会使用新的证书连接到 Kubernetes API。
当签署的证书即将到期时，kubelet 会使用 Kubernetes API，发起新的证书签名请求。 同样地，控制器管理器会自动批准证书请求，并将签署的证书附加到证书签名请求中。 Kubelet 会从 Kubernetes API 取回签署的证书，并将其写入磁盘。 然后它会更新与 Kubernetes API 的连接，使用新的证书重新连接到 Kubernetes API。
