## 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`
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
`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
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
[`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

|
||||||
|
|
||||||
|
## 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。 |
|
||||||
|
|
||||||
|

|
|
||||||
|
## 一：环境准备
|
||||||
|
|
||||||
|
三台服务器，一台master，两台node,master节点必须是2核cpu
|
||||||
|
|
||||||
|
| 节点名称 | IP地址 |
|
||||||
|
| :------: | :--------: |
|
||||||
|
| master | 10.0.0.220 |
|
||||||
|
| node-1 | 10.0.0.221 |
|
||||||
|
| node-2 | 10.0.0.222 |
|
||||||
|
| node-3 | 10.0.0.223 |
|
||||||
|
|
||||||
|
#### 1.所有服务器关闭防火墙和selinux
|
||||||
|
|
||||||
|
```shell
|
||||||
|
[root@localhost ~]# systemctl stop firewalld
|
||||||
|
[root@localhost ~]# systemctl disable firewalld
|
||||||
|
[root@localhost ~]# setenforce 0
|
||||||
|
[root@localhost ~]# sed -i '/^SELINUX=/c SELINUX=disabled/' /etc/selinux/config
|
||||||
|
[root@localhost ~]# swapoff -a 临时关闭
|
||||||
|
[root@localhost ~]# sed -i 's/.*swap.*/#&/' /etc/fstab 永久关闭
|
||||||
|
注意：
|
||||||
|
关闭所有服务器的交换分区
|
||||||
|
所有节点操作
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 2.保证yum仓库可用
|
||||||
|
|
||||||
|
```shell
|
||||||
|
[root@localhost ~]# yum clean all
|
||||||
|
[root@localhost ~]# yum makecache fast
|
||||||
|
注意：
|
||||||
|
使用国内yum源
|
||||||
|
所有节点操作
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 3.修改主机名
|
||||||
|
|
||||||
|
```shell
|
||||||
|
[root@localhost ~]# hostnamectl set-hostname master
|
||||||
|
[root@localhost ~]# hostnamectl set-hostname node-1
|
||||||
|
[root@localhost ~]# hostnamectl set-hostname node-2
|
||||||
|
[root@localhost ~]# hostnamectl set-hostname node-3
|
||||||
|
注意：
|
||||||
|
所有节点操作
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 4.添加本地解析
|
||||||
|
|
||||||
|

|
||||||
|
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
