+
+## 一：Service
+
+​		将运行在一组 [Pods](https://v1-23.docs.kubernetes.io/docs/concepts/workloads/pods/pod-overview/) 上的应用程序公开为网络服务的抽象方法
+
+​		使用 Kubernetes，你无需修改应用程序即可使用不熟悉的服务发现机制；Kubernetes 为 Pods 提供自己的 IP 地址，并为一组 Pod 提供相同的 DNS 名， 并且可以在它们之间进行负载均衡
+
+​		Kubernetes Service 定义了这样一种抽象：逻辑上的一组 Pod，一种可以访问它们的策略 —— 通常称为微服务
+
+​		举个例子，考虑一个图片处理后端，它运行了 3 个副本。这些副本是可互换的 —— 前端不需要关心它们调用了哪个后端副本。 然而组成这一组后端程序的 Pod 实际上可能会发生变化， 前端客户端不应该也没必要知道，而且也不需要跟踪这一组后端的状态
+
+#### 1.定义 Service
+
+例如，假定有一组 Pod，它们对外暴露了 9376 端口，同时还被打上 `app=MyApp` 标签：
+
+```shell
+apiVersion: v1
+kind: Service
+metadata:
+  name: my-service
+spec:
+  selector:
+    app: MyApp
+  ports:
+    - protocol: TCP
+      port: 80
+      targetPort: 9376
+```
+
+上述配置创建一个名称为 "my-service" 的 Service 对象，它会将请求代理到使用 TCP 端口 9376，并且具有标签 `"app=MyApp"` 的 Pod 上
+
+Kubernetes 为该服务分配一个 IP 地址（有时称为 "集群IP"），该 IP 地址由服务代理使用
+
+注意：
+
+​		Service 能够将一个接收 `port` 映射到任意的 `targetPort`。 默认情况下，`targetPort` 将被设置为与 `port` 字段相同的值
+
+#### 2.多端口 Service
+
+​		对于某些服务，你需要公开多个端口。 Kubernetes 允许你在 Service 对象上配置多个端口定义
+
+```shell
+apiVersion: v1
+kind: Service
+metadata:
+  name: my-service
+spec:
+  selector:
+    app: MyApp
+  ports:
+    - name: http
+      protocol: TCP
+      port: 80
+      targetPort: 9376
+    - name: https
+      protocol: TCP
+      port: 443
+      targetPort: 9377
+```
+
+## 二：发布服务
+
+#### 1.服务类型
+
+ClusterIP
+
+NodePort
+
+LoadBalancer
+
+ExternalName
+
+#### 2.服务类型
+
+​		对一些应用的某些部分（如前端），可能希望将其暴露给 Kubernetes 集群外部 的 IP 地址
+
+​		Kubernetes `ServiceTypes` 允许指定你所需要的 Service 类型，默认是 `ClusterIP`
+
+`Type` 的取值以及行为如下：
+
+​		`ClusterIP`：通过集群的内部 IP 暴露服务，选择该值时服务只能够在集群内部访问。 这也是默认的 `ServiceType`
+
+ ![img](https://xingdian-image.oss-cn-beijing.aliyuncs.com/xingdian-image/6R1zaHS1QM_i4c4W1k2ttg.png)   
+
+​		`NodePort`：通过每个节点上的 IP 和静态端口（`NodePort`）暴露服务。 `NodePort` 服务会路由到自动创建的 `ClusterIP` 服务。 通过请求 `<节点 IP>:<节点端口>`，你可以从集群的外部访问一个 `NodePort` 服务
+
+  ![img](https://xingdian-image.oss-cn-beijing.aliyuncs.com/xingdian-image/-E5GOvNElgId7mwjBs9elw.png)      
+
+​		[`LoadBalancer`](https://v1-23.docs.kubernetes.io/zh/docs/concepts/services-networking/service/#loadbalancer)：使用云提供商的负载均衡器向外部暴露服务。 外部负载均衡器可以将流量路由到自动创建的 `NodePort` 服务和 `ClusterIP` 服务上
+
+​		你也可以使用Ingress来暴露自己的服务。 Ingress 不是一种服务类型，但它充当集群的入口点。 它可以将路由规则整合到一个资源中，因为它可以在同一IP地址下公开多个服务
+
+```shell
+[root@master nginx]# kubectl expose deployment nginx-deployment --port=80 --type=LoadBalancer
+```
+
+#### 3.NodePort
+
+​		如果你将 `type` 字段设置为 `NodePort`，则 Kubernetes 控制平面将在 `--service-node-port-range` 标志指定的范围内分配端口（默认值：30000-32767）
+
+例如：
+
+```shell
+apiVersion: v1
+kind: Service
+metadata:
+  name: my-service
+spec:
+  type: NodePort
+  selector:
+    app: MyApp
+  ports:
+      # 默认情况下，为了方便起见，`targetPort` 被设置为与 `port` 字段相同的值。
+    - port: 80
+      targetPort: 80
+      # 可选字段
+      # 默认情况下，为了方便起见，Kubernetes 控制平面会从某个范围内分配一个端口号（默认：30000-32767）
+      nodePort: 30007
+```
+
+#### 4.案例
+
+```shell
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: nginx-deployment
+spec:
+  replicas: 3
+  selector:
+    matchLabels:
+      app: nginx
+  template:
+    metadata:
+      labels:
+        app: nginx
+    spec:
+      containers:
+      - name: nginx-server
+        image: nginx:1.16
+        ports:
+        - containerPort: 80
+```
+
+```shell
+apiVersion: v1
+kind: Service
+metadata:
+  name: nginx-services
+  labels:
+    app: nginx
+spec:
+  type: NodePort
+  ports:
+  - port: 88
+    targetPort: 80
+    nodePort: 30010
+  selector:
+    app: nginx
+```
+
+#### 5.了解
+
+​	`ExternalName` 是 `Kubernetes` 服务（`Service`）类型中的一种，它允许你将服务映射到一个外部的 DNS 名称，而不是选择器（`selector`）所定义的一组 Pod；这意味着当你在集群内部通过服务名称访问时，实际上是在访问外部指定的资源。
+
+使用场景
+
+​	`ExternalName` 类型的服务非常适合以下几种情况：
+
+​	当你需要将内部服务指向外部系统或第三方 API
+
+​	当你希望服务名称和外部资源名称之间保持解耦，即使外部资源发生变化，只需要更新服务配置
+
+​	对于微服务架构中的跨团队合作，不同团队管理自己的服务，通过 `ExternalName` 来互相调用对方的服务
+
+配置方式
+
+​	创建一个 `ExternalName` 类型的服务非常简单，只需在服务定义文件中设置 `spec.type` 为 `ExternalName` 并提供 `spec.externalName` 字段来指明你要映射的外部域名
+
+```yaml
+apiVersion: v1
+kind: Service
+metadata:
+  name: external-service
+  namespace: default
+spec:
+  type: ExternalName
+  externalName: example.com
+```
+
+案例
+
+​	假设你正在管理一个电子商务平台，该平台由多个微服务组成，并且有一个专门处理支付的外部服务，这个支付服务是由第三方提供商托管的，其域名是 `payments.externalprovider.com`
+
+背景
+
+​	你的电商平台需要调用支付网关来完成交易过程。支付网关是一个由外部供应商提供的服务，不在你的 `Kubernetes`集群内运行，但是你的应用程序代码需要能够像调用内部服务一样方便地访问它
+
+使用 `ExternalName` 服务
+
+​	为了简化与外部支付服务的交互，你可以创建一个名为 payment-gateway 的 ExternalName 类型的服务，这样所有的内部服务就可以通过 payment-gateway.default.svc.cluster.local（假设在默认命名空间中）来访问外部的支付服务，而不需要直接硬编码外部域名
+
+```yaml
+apiVersion: v1
+kind: Service
+metadata:
+  name: payment-gateway
+  namespace: default
+spec:
+  type: ExternalName
+  externalName: payments.externalprovider.com
+```
+
+应用程序代码调整
+
+​	在你的应用程序代码中，你只需要配置服务名称为 payment-gateway 或者根据集群内的 DNS 解析规则使用完整的 FQDN (Fully Qualified Domain Name) payment-gateway.default.svc.cluster.local 来发起请求。比如，在 Java Spring Boot 应用中，你可以设置 REST 客户端的基础 URL：
+
+```java
+@Bean
+public RestTemplate restTemplate(RestTemplateBuilder builder) {
+    // 注意这里使用的是服务名称，而不是直接使用外部域名
+    return builder.rootUri("http://payment-gateway").build();
+}
+```
+
+总结
+
+​	通过这种方式，`ExternalName` 服务帮助你在`Kubernetes` 环境中优雅地整合了外部依赖，同时保持了良好的抽象层次和灵活性

+<h1><center>Kubernetes资源对象Volumes</center></h1>
+
+著作：行癫  <盗版必究>
+
+------
+
+## 一：Volumes
+
+​		Container 中的文件在磁盘上是临时存放的，这给 Container 中运行的较重要的应用 程序带来一些问题。问题之一是当容器崩溃时文件丢失。kubelet 会重新启动容器， 但容器会以干净的状态重启。 第二个问题会在同一 Pod中运行多个容器并共享文件时出现。 Kubernetes 卷（Volume） 这一抽象概念能够解决这两个问题。
+
+​		Docker 也有 卷（Volume） 的概念，但对它只有少量且松散的管理。 Docker 卷是磁盘上或者另外一个容器内的一个目录。 Docker 提供卷驱动程序，但是其功能非常有限。
+
+​		Kubernetes 支持很多类型的卷。 Pod 可以同时使用任意数目的卷类型。 临时卷类型的生命周期与 Pod 相同，但持久卷可以比 Pod 的存活期长。 因此，卷的存在时间会超出 Pod 中运行的所有容器，并且在容器重新启动时数据也会得到保留。 当 Pod 不再存在时，卷也将不再存在。
+
+​		卷的核心是包含一些数据的一个目录，Pod 中的容器可以访问该目录。 所采用的特定的卷类型将决定该目录如何形成的、使用何种介质保存数据以及目录中存放的内容。
+
+​		使用卷时, 在 .spec.volumes字段中设置为 Pod 提供的卷，并在.spec.containers[*].volumeMounts字段中声明卷在容器中的挂载位置。
+
+#### 1.cephfs
+
+​		cephfs卷允许你将现存的 CephFS 卷挂载到 Pod 中。 不像emptyDir那样会在 Pod 被删除的同时也会被删除，cephfs卷的内容在 Pod 被删除 时会被保留，只是卷被卸载了。这意味着 cephfs 卷可以被预先填充数据，且这些数据可以在 Pod 之间共享。同一cephfs卷可同时被多个写者挂载。
+
+详细使用官方链接:
+
+```shell
+https://github.com/kubernetes/examples/tree/master/volumes/cephfs/
+```
+
+#### 2.hostPath
+
+​		hostPath卷能将主机节点文件系统上的文件或目录挂载到你的 Pod 中。 虽然这不是大多数 Pod 需要的，但是它为一些应用程序提供了强大的逃生舱。
+
+|     **取值**      |                           **行为**                           |
+| :---------------: | :----------------------------------------------------------: |
+|                   | 空字符串（默认）用于向后兼容，这意味着在安装 hostPath 卷之前不会执行任何检查。 |
+| DirectoryOrCreate | 如果在给定路径上什么都不存在，那么将根据需要创建空目录，权限设置为 0755，具有与 kubelet 相同的组和属主信息。 |
+|     Directory     |                 在给定路径上必须存在的目录。                 |
+|   FileOrCreate    | 如果在给定路径上什么都不存在，那么将在那里根据需要创建空文件，权限设置为 0644，具有与 kubelet 相同的组和所有权。 |
+|       File        |                 在给定路径上必须存在的文件。                 |
+|      Socket       |             在给定路径上必须存在的 UNIX 套接字。             |
+|    CharDevice     |               在给定路径上必须存在的字符设备。               |
+|    BlockDevice    |                在给定路径上必须存在的块设备。                |
+
+hostPath 配置示例：
+
+```shell
+apiVersion: v1
+kind: Pod
+metadata:
+  name: test-pd
+spec:
+  containers:
+  - image: k8s.gcr.io/test-webserver
+    name: test-container
+    volumeMounts:
+    - mountPath: /test-pd
+      name: test-volume
+  volumes:
+  - name: test-volume
+    hostPath:
+      # 宿主上目录位置
+      path: /data
+      # 此字段为可选
+      type: Directory

+[root@master ~]# systemctl start docker
+[root@master ~]# systemctl enable docker
+注意：
+	所有节点操作
+```
+
+#### 6.安装kubeadm和kubelet
+
+```shell
+[root@master ~]# cat >> /etc/yum.repos.d/kubernetes.repo <<eof
+[kubernetes]
+name=Kubernetes
+baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64

+net.bridge.bridge-nf-call-ip6tables = 1
+net.bridge.bridge-nf-call-iptables = 1
+vm.swappiness = 0
+注意：
+	所有节点操作
+```
+
+## 二：部署Kubernetes
+
+#### 1.镜像下载
+
+```shell
+https://www.xingdiancloud.cn/index.php/s/6GyinxZwSRemHPz
+注意：
+	下载后上传到所有节点
+```
+
+#### 2.镜像导入
+
+```shell
+[root@master ~]# cat image_load.sh
+#!/bin/bash
+image_path=`pwd`
+for i in `ls "${image_path}" | grep tar`
+do
+        docker load  < $i
+done
+[root@master ~]# bash image_load.sh
+注意：
+	所有节点操作
+```
+
+#### 3.master节点初始化
+
+```shell
+[root@master ~]# kubeadm init --kubernetes-version=1.23.1 --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=10.0.0.220
+
+Your Kubernetes control-plane has initialized successfully!
+
+To start using your cluster, you need to run the following as a regular user:
+
+  mkdir -p $HOME/.kube
+  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
+  sudo chown $(id -u):$(id -g) $HOME/.kube/config
+
+Alternatively, if you are the root user, you can run:
+
+  export KUBECONFIG=/etc/kubernetes/admin.conf
+
+You should now deploy a pod network to the cluster.
+Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
+  https://kubernetes.io/docs/concepts/cluster-administration/addons/
+
+Then you can join any number of worker nodes by running the following on each as root:
+
+kubeadm join 10.0.0.220:6443 --token mzrm3c.u9mpt80rddmjvd3g \
+        --discovery-token-ca-cert-hash sha256:fec53dfeacc5187d3f0e3998d65bd3e303fa64acd5156192240728567659bf4a
+```
+
+#### 4.安装pod插件
+
+```shell
+[root@master ~]# wget http://www.xingdiancloud.cn:92/index.php/s/3Ad7aTxqPPja24M/download/flannel.yaml
+[root@master ~]# kubectl create -f flannel.yaml
+```
+
+#### 5.将node加入工作节点
+
+```shell
+[root@node-1 ~]# kubeadm join 10.0.0.220:6443 --token mzrm3c.u9mpt80rddmjvd3g --discovery-token-ca-cert-hash sha256:fec53dfeacc5187d3f0e3998d65bd3e303fa64acd5156192240728567659bf4a
+注意：
+这里使用的是master初始化产生的token
+这里的token时间长了会改变，需要使用命令获取，见下期内容
+没有记录集群 join 命令的可以通过以下方式重新获取:
+kubeadm token create --print-join-command --ttl=0
+```
+
+#### 6.master节点查看集群状态
+
+```shell
+[root@master ~]# kubectl get nodes
+NAME     STATUS   ROLES                  AGE     VERSION
+master   Ready    control-plane,master   26m     v1.23.1
+node-1   Ready    <none>                 4m45s   v1.23.1
+node-2   Ready    <none>                 4m40s   v1.23.1
+node-3   Ready    <none>                 4m46s   v1.23.1
+```

+
+#### 3.master节点初始化
+
+```shell
+[root@master ~]# kubeadm init --kubernetes-version=1.23.1 --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=10.0.0.220
+
+Your Kubernetes control-plane has initialized successfully!
+
+To start using your cluster, you need to run the following as a regular user:
+
+  mkdir -p $HOME/.kube
+  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
+  sudo chown $(id -u):$(id -g) $HOME/.kube/config
+
+Alternatively, if you are the root user, you can run:
+
+  export KUBECONFIG=/etc/kubernetes/admin.conf
+
+You should now deploy a pod network to the cluster.
+Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
+  https://kubernetes.io/docs/concepts/cluster-administration/addons/
+
+Then you can join any number of worker nodes by running the following on each as root:
+
+kubeadm join 10.0.2.150:6443 --token tlohed.bwgh4tt5erbc2zhg \
+        --discovery-token-ca-cert-hash sha256:9b28238c55bf5b2e5e0d68c6303e50bf6f12e7e07126897c846a4f5328157e16 
+```
+
+#### 4.安装pod插件

+
+#### 5.将node加入工作节点
+
+```shell
+[root@node-1 ~]# kubeadm join 10.0.0.220:6443 --token mzrm3c.u9mpt80rddmjvd3g --discovery-token-ca-cert-hash sha256:fec53dfeacc5187d3f0e3998d65bd3e303fa64acd5156192240728567659bf4a
+注意：
+这里使用的是master初始化产生的token
+这里的token时间长了会改变，需要使用命令获取，见下期内容
+没有记录集群 join 命令的可以通过以下方式重新获取:
+kubeadm token create --print-join-command --ttl=0
+```
+
+#### 6.master节点查看集群状态
+
+```shell
+[root@master ~]# kubectl get node
+NAME     STATUS   ROLES           AGE    VERSION
+master   Ready    control-plane   7m     v1.25.0
+node-1   Ready    <none>          2m7s   v1.25.0
+node-2   Ready    <none>          50s    v1.25.0
+node-3   Ready    <none>          110s   v1.25.0
+```
+
+## 三：部署Dashboard
+
+#### 1.kube-proxy 开启 ipvs
+
+```shell
+[root@master ~]# kubectl get configmap kube-proxy -n kube-system -o yaml > kube-proxy-configmap.yaml
+[root@master ~]# sed -i 's/mode: ""/mode: "ipvs"/' kube-proxy-configmap.yaml
+[root@master ~]# kubectl apply -f kube-proxy-configmap.yaml
+[root@master ~]# rm -f kube-proxy-configmap.yaml
+[root@master ~]# kubectl get pod -n kube-system | grep kube-proxy | awk '{system("kubectl delete pod "$1" -n kube-system")}' 
+```
+
+#### 2.Dashboard安装脚本
+
+```shell
+[root@master ~]# cat dashboard.yaml
