* 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

管理巨页(HugePages) | templates/task |
{{% capture overview %}} {{< feature-state state="alpha" >}}
作为 alpha 特性,Kubernetes 支持在 Pod 应用中使用预先分配的巨页(或称“大页面”,下文统称为“巨页”)。 本文描述了用户如何使用巨页,以及当前的限制。
{{% /capture %}}
{{% capture prerequisites %}}
- 为了使节点能够上报巨页容量,Kubernetes 节点必须预先分配巨页。 每个节点只能预先分配一种特定规格的巨页。
- 用户必须在整个系统中将专用的 alpha 特性开关
HugePages设置为 true:--feature-gates=HugePages=true。
节点会自动发现全部巨页资源,并作为可供调度的资源进行上报。
{{% /capture %}}
{{% capture steps %}}
API
用户可以通过在容器级别的资源需求中使用资源名称 hugepages-<size> 来使用巨页,其中的 size 是特定节点上支持的以整数值表示的最小二进制单位。 例如,如果节点支持 2048KiB 的页面规格, 它将暴露可供调度的资源 hugepages-2Mi。 与 CPU 或内存不同,巨页不支持过量使用(overcommit)。
apiVersion: v1
kind: Pod
metadata:
generateName: hugepages-volume-
spec:
containers:
- image: fedora:latest
command:
- sleep
- inf
name: example
volumeMounts:
- mountPath: /hugepages
name: hugepage
resources:
limits:
hugepages-2Mi: 100Mi
volumes:
- name: hugepage
emptyDir:
medium: HugePages
- 巨页的资源需求和限制必须相等。 该条件在指定了资源限制,而没有指定需求的情况下默认成立。
- 巨页是被隔离在 pod 作用域的,计划在将来的迭代中实现容器级别的隔离。
- 巨页对 EmptyDir 卷提供支持,EmptyDir 卷所使用的巨页,不能够超出 pod 请求的内存容量。
- 通过带有
SHM_HUGETLB的shmget()使用巨页的应用,必须运行在一个与proc/sys/vm/hugetlb_shm_group匹配的补充组下。
(待实现的)特性
- 在 pod 级别隔离的基础上,支持巨页在容器级别的隔离。
- 作为服务质量特性,保证巨页的 NUMA 局部性。
- 支持 ResourceQuota 。
- 支持 LimitRange 。
