# Homebrew安装
macOS我们可以使用Homebrew来安装docker Homebrew 的 Cask 已经支持 Docker for Mac，因此可以很方便的使用 Homebrew Cask 来进行安装：
# 安装命令
brew cask install docker
==> Satisfying dependencies
==> Downloading https://download.docker.com/mac/stable/28905/Docker.dmg
######################################################################## 100.0%
==> Verifying SHA-256 checksum for Cask 'docker'.
==> Installing Cask docker
==> Moving App 'Docker.app' to '/Applications/Docker.app'.

# 手动安装
下载最新的Docker for Mac或者Edge版本，即可以看到内置的kubernets集群，直接点击安装即可
安装完毕后，如果页勾选了Show system containers选项，那么使用如下的Docker命令，能看到自动安装的kubernetes相关容器：
➜ ~ docker container ls --format "table{{.Names}}\t{{.Image }}\t{{.Command}}"

关于各个容器的作用，可以残月这里 (opens new window)。在安装过程中，Docker页为我们安装了kubectl控制命令：
$ kubectl get namespaces
$ kubectl get posts --namespace kube-system

接下来我们可以使用kubectl命令来创建简单的kubernets-dashboard服务：
➜ ~ kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml
secret "kubernetes-dashboard-certs" created
serviceaccount "kubernetes-dashboard" created
role "kubernetes-dashboard-minimal" created
rolebinding "kubernetes-dashboard-minimal" created
deployment "kubernetes-dashboard" created
service "kubernetes-dashboard" created

服务安装完毕后可以查看部署的容器和服务：
➜ ~ kubectl get deployments --namespace kube-system
NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE
kube-dns 1 1 1 1 22m
kubernetes-dashboard 1 1 1 0 26s
➜ ~ kubectl get services --namespace kube-system

kube-dns ClusterIP 10.96.0.10 <none> 53/UDP,53/TCP 22m

在Dashboard启动完毕后，可以使用kubectl提供的Proxy服务来访问该面板：
$ kubectl proxy
# 打开如下地址：

如果访问出错，可以尝试kubernetes-dashboard服务，或者查阅这里 (opens new window)
$ kubectl -n kube-system edit service kubernetes-dashboard
# Please edit the object below. Lines beginning with a '#' will be ignored,
# and an empty file will abort the edit. If an error occurs while saving this file will be
# reopened with the relevant failures.

访问上述地址，我们可以看到登陆界面：
此时可暂时直接跳过，进入到控制面板中
Docker同样为我们提供了简单的应用示范，可以直接使用如下的Docker Compose配置文件：
version: '3.3'
services:
web:
build: web
image: dockerdemos/lab-web
volumes:
- "./web/static:/static"
ports:
- "80:80"
words:
build: words
image: dockerdemos/lab-words
deploy:
replicas: 5
endpoint_mode: dnsrr

然后使用stack命令创建应用栈：
$ docker stack deploy --compose-file stack.yml demo
Stack demo was created
Waiting for the stack to be stable and running...

应用栈创建完毕后，可以使kubectl查看创建的Pods:
$ kubectl get pods

也可以来查看部署的集群与服务：
$ kubectl get deployments
NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE
db 1 1 1 1 3m
web 1 1 1 1 3m
words 5 5 5 5 3m
$ kubectl get services
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
db ClusterIP None <none> 55555/TCP 3m
kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 52m
web LoadBalancer 10.97.154.28 <pending> 80:30577/TCP 3m

可以看到这里的web有所谓的LoadBalancer类型，机可以对外提供服务。最后我们可以用stack与kubectl名利ing来删除应用：
$ docker stack remove demo
$ kubectl delete deployment kubernetes-dashboard --namespace kube-system

# 镜像加速
鉴于国内网络问题，后续拉取Docker镜像十分缓慢，我们需要配置加速期来解决，
- 官网 (opens new window)
- 网易 (opens new window)
- 阿里云 (opens new window): 阿里云的镜像官方地址是：http://dev.aliyun.com/search.html， 开发这需要开通阿里开发者账户，登陆后https://cr.console.aliyun.com/undefined/instances/mirrors 中查看你的专属加速器地址
