基於kubernetes平台微服務的部署
基於kubernetes平台微服務的部署
首先下載插件：
kubernetes Continuous Deploy
然後去找 .kube/ 里的config 複製裡面的內容
去添加憑據：
然後就是腳本更新：
def git_address = "//20.0.0.20:82/root/tensquare_back.git"
def git_auth = "904eff5d-41c8-44ad-ba24-7f539a0edb96"
//構建版本的名稱
def tag = "latest"
//Harbor私服地址
def harbor_url = "20.0.0.50:85"
//Harbor的項目名稱
def harbor_project_name = "tensquare"
//Harbor的憑證
def harbor_auth = "427399a8-db35-48e8-b5cf-a1ea63f10cc5"
//k8s的憑證
def k8s_auth="4f3c9e60-da07-49b3-89ae-d708516e8071"
//定義k8s-barbor的憑證
def secret_name="registry-auth-secret"
podTemplate(label: 'jenkins-slave', cloud: 'kubernetes', containers: [
containerTemplate(
name: 'jnlp',
image: "20.0.0.50:85/library/jenkins-slave-maven:latest"
),
containerTemplate(
name: 'docker',
image: "docker:stable",
ttyEnabled: true,
command: 'cat'
),
],
volumes: [
hostPathVolume(mountPath: '/var/run/docker.sock', hostPath: '/var/run/docker.sock'),
nfsVolume(mountPath: '/usr/local/apache-maven/repo', serverAddress: '20.0.0.10' , serverPath: '/opt/nfs/maven'),
],
)
{
node("jenkins-slave"){
// 第一步
stage('pull code'){
checkout([$class: 'GitSCM', branches: [[name: '*/master']], extensions: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_address}"]]])
}
// 第二步
stage('make public sub project'){
//編譯並安裝公共工程
sh "mvn -f tensquare_common clean install"
}
// 第三步
stage('make image'){
//把選擇的項目資訊轉為數組
def selectedProjects = "${project_name}".split(',')
for(int i=0;i<selectedProjects.size();i++){
//取出每個項目的名稱和埠
def currentProject = selectedProjects[i];
//項目名稱
def currentProjectName = currentProject.split('@')[0]
//項目啟動埠
def currentProjectPort = currentProject.split('@')[1]
//定義鏡像名稱
def imageName = "${currentProjectName}:${tag}"
//編譯，構建本地鏡像
sh "mvn -f ${currentProjectName} clean package dockerfile:build"
container('docker') {
//給鏡像打標籤
sh "docker tag ${imageName} ${harbor_url}/${harbor_project_name}/${imageName}"
//登錄Harbor，並上傳鏡像
withCredentials([usernamePassword(credentialsId: "${harbor_auth}", passwordVariable: 'password', usernameVariable: 'username')])
{
//登錄
sh "docker login -u ${username} -p ${password} ${harbor_url}"
//上傳鏡像
sh "docker push ${harbor_url}/${harbor_project_name}/${imageName}"
}
//刪除本地鏡像
sh "docker rmi -f ${imageName}"
sh "docker rmi -f ${harbor_url}/${harbor_project_name}/${imageName}"
}
def deploy_image_name = "${harbor_url}/${harbor_project_name}/${imageName}"
//部署到K8S
sh """
sed -i 's#\$IMAGE_NAME#${deploy_image_name}#' ${currentProjectName}/deploy.yml
sed -i 's#\$SECRET_NAME#${secret_name}#' ${currentProjectName}/deploy.yml
"""
kubernetesDeploy configs: "${currentProjectName}/deploy.yml", kubeconfigId: "${k8s_auth}"
}
}
}
}
要更改的就是：
添加k8s的憑證：
然後在eureka 目錄下創建deploy文件：
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: "//eureka-0.eureka:10086/eureka/,//eureka- 1.eureka:10086/eureka/"
- name: EUREKA_INSTANCE_HOSTNAME
value: ${MY_POD_NAME}.eureka
podManagementPolicy: "Parallel"
裡面的application.yml配置文件更改如下：
server:
port: ${PORT:10086}
spring:
application:
name: eureka
eureka:
server:
# 續期時間，即掃描失效服務的間隔時間（預設為60*1000ms）
eviction-interval-timer-in-ms: 5000
enable-self-preservation: false
use-read-only-response-cache: false
client:
# eureka client間隔多久去拉取服務註冊資訊 默認30s
registry-fetch-interval-seconds: 5
serviceUrl:
defaultZone: ${EUREKA_SERVER://127.0.0.1:${server.port}/eureka/}
instance:
# 心跳間隔時間，即發送一次心跳之後，多久在發起下一次（預設為30s）
lease-renewal-interval-in-seconds: 5
# 在收到一次心跳之後，等待下一次心跳的空檔時間，大於心跳間隔即可，即服務續約到期時間（預設為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}}
然後在提交前在k8s所有主機上操作
docker login -u lvbu -p Lvbu1234 20.0.0.50:85
kubectl create secret docker-registry registry-auth-secret --docker-server=20.0.0.50:85 --docker-username=lvbu --docker-password=Lvbu1234 -- [email protected]
然後去提交之前的修改的配置
提交完之後就可以構建了！
然後去查看：
kubectl get secrets
kubectl get pods
kubectl get servicef 查看能看到埠 訪問node節點的埠 就會發現註冊中心有了
然後部署服務網關：
同理更改配置文件中的eureka集群地址：
//eureka-0.eureka:10086/eureka/,//eureka- 1.eureka:10086/eureka/
所有的都要更改！
然後一樣的操作在網關低下創建deploy.yml文件：
內容如下：
---
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"
在提交前先去手動上傳父工程依賴到NFS的maven共享倉庫目錄中：
然後在構建！
然後就是部署admin_service：
也是創建deploy.yml：
---
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"
然後 集群地址也要更改！
接下來的部署gatjering 也是如此：
deploy.yml文件如下：
---
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！
然後就可以一次性提交程式碼然後一次性構建！
結果如下：
