基于kubernetes平台微服务的部署

基于kubernetes平台微服务的部署

首先下载插件：

kubernetes Continuous Deploy

然后去找 .kube/ 里的config 复制里面的内容

 

去添加凭据：

 

 

 

 

 

 

然后就是脚本更新：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93

要更改的就是：

添加k8s的凭证：

 

 

 

然后在eureka 目录下创建deploy文件：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

metadata:   name: eureka spec:   serviceName: "eureka"   replicas: 2   selector:     matchLabels:       app: eureka   template:     metadata:       labels:         app: eureka     spec:       imagePullSecrets:         - name: $SECRET_NAME       containers:         - name: eureka           image: $IMAGE_NAME           ports:             - containerPort: 10086           env:             - name: MY_POD_NAME               valueFrom:                 fieldRef:                   fieldPath: metadata.name             - name: EUREKA_SERVER               value: "http://eureka-0.eureka:10086/eureka/,http://eureka- 1.eureka:10086/eureka/"             - name: EUREKA_INSTANCE_HOSTNAME               value: ${MY_POD_NAME}.eureka   podManagementPolicy: "Parallel"

　　

里面的application.yml配置文件更改如下：

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

server:   port: ${PORT:10086} spring:   application:     name: eureka   eureka:   server:     # 续期时间，即扫描失效服务的间隔时间（缺省为60*1000ms）     eviction-interval-timer-in-ms: 5000     enable-self-preservation: false     use-read-only-response-cache: false   client:     # eureka client间隔多久去拉取服务注册信息 默认30s     registry-fetch-interval-seconds: 5     serviceUrl:       defaultZone: ${EUREKA_SERVER:http://127.0.0.1:${server.port}/eureka/}   instance:     # 心跳间隔时间，即发送一次心跳之后，多久在发起下一次（缺省为30s）     lease-renewal-interval-in-seconds: 5     #  在收到一次心跳之后，等待下一次心跳的空档时间，大于心跳间隔即可，即服务续约到期时间（缺省为90s）     lease-expiration-duration-in-seconds: 10     instance-id: ${EUREKA_INSTANCE_HOSTNAME:${spring.application.name}}:${server.port}@${random.l ong(1000000,9999999)}     hostname: ${EUREKA_INSTANCE_HOSTNAME:${spring.application.name}}

 

　

 

然后在提交前在k8s所有主机上操作

?

1	docker login -u lvbu -p Lvbu1234 20.0.0.50:85

?

1	kubectl create secret docker-registry registry-auth-secret --docker-server=20.0.0.50:85 --docker-username=lvbu --docker-password=Lvbu1234 -- docker-email=lbu@qq.com

　　

然后去提交之前的修改的配置

 

提交完之后就可以构建了！

然后去查看：

?

1	kubectl get secrets

?

1	kubectl get pods

?

1	kubectl get servicef  查看能看到端口 访问node节点的端口  就会发现注册中心有了

 

 

然后部署服务网关：

同理更改配置文件中的eureka集群地址：

?

1	http://eureka-0.eureka:10086/eureka/,http://eureka- 1.eureka:10086/eureka/

所有的都要更改！

 

然后一样的操作在网关低下创建deploy.yml文件：

内容如下：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

--- apiVersion: v1 kind: Service metadata:   name: zuul   labels:     app: zuul spec:   type: NodePort   ports:     - port: 10020       name: zuul       targetPort: 10020   selector:     app: zuul --- apiVersion: apps/v1 kind: StatefulSet metadata:   name: zuul spec:   serviceName: "zuul"   replicas: 2   selector:     matchLabels:       app: zuul   template:     metadata:       labels:         app: zuul     spec:       imagePullSecrets:         - name: $SECRET_NAME       containers:         - name: zuul           image: $IMAGE_NAME           ports:             - containerPort: 10020   podManagementPolicy: "Parallel"

　　

在提交前先去手动上传父工程依赖到NFS的maven共享仓库目录中：

 

 

　　

然后在构建！

 

 

 

然后就是部署admin_service：

也是创建deploy.yml：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

--- apiVersion: v1 kind: Service metadata:   name: admin   labels:     app: admin spec:   type: NodePort   ports:     - port: 9001       name: admin       targetPort: 9001   selector:     app: admin --- apiVersion: apps/v1 kind: StatefulSet metadata:   name: admin spec:   serviceName: "admin"   replicas: 2   selector:     matchLabels:       app: admin   template:     metadata:       labels:         app: admin     spec:       imagePullSecrets:         - name: $SECRET_NAME       containers:         - name: admin           image: $IMAGE_NAME           ports:             - containerPort: 9001   podManagementPolicy: "Parallel"

　　

然后 集群地址也要更改！

 

接下来的部署gatjering  也是如此：

deploy.yml文件如下：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

--- apiVersion: v1 kind: Service metadata:   name: gathering   labels:     app: gathering spec:   type: NodePort   ports:     - port: 9002       name: gathering       targetPort: 9002   selector:     app: gathering --- apiVersion: apps/v1 kind: StatefulSet metadata:   name: gathering spec:   serviceName: "gathering"   replicas: 2   selector:     matchLabels:       app: gathering   template:     metadata:       labels:         app: gathering     spec:       imagePullSecrets:         - name: $SECRET_NAME       containers:         - name: gathering           image: $IMAGE_NAME           ports:             - containerPort: 9002   podManagementPolicy: "Parallel"

　　

也要修改集群地址eureka！

 

然后就可以一次性提交代码然后一次性构建！

结果如下：
