本地Kubernetes部署架构

校验Kubernetes安装

1、启动minikube作为Kubernetes Server端

minikube start

2、校验Kubernetes版本

$ kubectl version
Client Version: version.Info{Major:"1", Minor:"21", GitVersion:"v1.21.1", GitCommit:"5e58841cce77d4bc13713ad2b91fa0d961e69192", GitTreeState:"clean", BuildDate:"2021-05-12T14:18:45Z", GoVersion:"go1.16.4", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"20", GitVersion:"v1.20.2", GitCommit:"faecb196815e248d3ecfb03c680a4507229c2a56", GitTreeState:"clean", BuildDate:"2021-01-13T13:20:00Z", GoVersion:"go1.15.5", Compiler:"gc", Platform:"linux/amd64"}

3、kubectl config current-context

$ kubectl config current-context
minikube

4、检查集群信息

$ kubectl cluster-info
Kubernetes control plane is running at https://192.168.49.2:8443
KubeDNS is running at https://192.168.49.2:8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

5、检查节点信息

$ kubectl get nodes
NAME       STATUS   ROLES                  AGE   VERSION
minikube   Ready    control-plane,master   16d   v1.20.2

安装和访问Kubernetes Dashboard

1、安装Kubernetes Dashboard

https://github.com/kubernetes/dashboard

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.3.1/aio/deploy/recommended.yaml

:::danger 如果未部署成功并且多次执行了apply命令，可能会出现如下报错：The ClusterRoleBinding "kubernetes-dashboard" is invalid: roleRef: Invalid value: rbac.RoleRef{APIGroup:"rbac.authorization.k8s.io", Kind:"ClusterRole", Name:"kubernetes-dashboard"}: cannot change roleRef原因是已经存在重复的ClusterRoleBinding，使用命令kubectl delete clusterrolebinding kubernetes-dashboard删除重复的绑定即可。然后再执行该命令则不会出现问题 :::

kubectl get pods --namespace=kubernetes-dashboard

:::tips 注意：这里的命令行参数--namespace后面的值要改为对应的YAML文件里面的Namespace的值 :::

2、启动Kube Proxy

kubectl proxy
# 如果kubernetes部署在服务器通过公网IP访问则使用下面的命令，否则默认绑定的是127.0.0.1
kubectl proxy --address='0.0.0.0'

3、生成访问令牌

kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | grep admin-user | awk '{print $1}')

4、访问Dashboard

http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/

Staffjoy部署到本地Kubernetes环境

1、镜像构建（可选）

mvn clean package -DskipTests
docker-compose build
docker images

服务容器化和Docker compose部署

2、部署MySQL数据库（可选）

• staffjoy_account
• staffjoy_company

  授予ip访问权限

  ```bash [root@iZuf68qk0bio1l786kylamZ ~]# docker exec -it mysql bash root@c4c2e8d188de:/# mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 39 Server version: 8.0.26 MySQL Community Server - GPL

<a name="sp0ra"></a>
### 3、部署Staffjoy（K8s/test）
```bash
kubectl apply -f config.yml

# 指定test目录下的所有yaml文件
kubectl apply -f test

4、端口转发

# 查询faraday pod名
kubectl get pods
kubectl poft-forward faraday-svc-deployment-8584d9c74d-v92wt 80:80

5、启动SwitchHosts

6、命令行校验

kubectl get pods -o wide
kubectl get services
kubectl get deployments

7、K8s Dashboard校验

8、Staffjoy校验

9、清理

kubectl delete deployment --all
kubectl delete service --all
kubectl delete configmaps --all

Staffjoy部署到阿里云Kubernetes架构

阿里云Kubernetes拓扑结构

https://developer.aliyun.com/article/88526

阿里云Kubernetes环境创建

1、创建VPC

2、创建RDS数据库

加IP白名单更新JDBC连接字符串创建ROOT帐号创建数据库和表

3、创建共享版Kubernetes集群

4、校验

kubectl config current-context
kubectl cluster-info
kubectl get nodes

Staffjoy部署

1、部署Staffjoy（Kubernetes/UAT）

kubectl apply -f config
kubectl apply -f uat

2、阿里云Dashboard校验

3、命令行校验

kubectl get pods -o wide
kubectl get services
kubectl get deployments

4、启用SwitchHosts

更新ELB IP地址

5、Staffjoy校验

6、删除阿里云Kubernetes和RDS
