1、编写pm2项目Dockerfile文件
遇到的一个问题：
当我们在Dockerfile中采用pm2 start的启动命令时，一直无法正常启动，最后改成pm2-runtime启动方式
具体文件如下

# Set the base image
FROM node:16.20.2WORKDIR /home/dex-transaction-ws# Copy files
COPY ./ /home/dex-transaction-ws/# Set ENV variables
ENV INAME=${SVC_NAME}# Install dependencies and compile
RUN npm install pm2 -g
#RUN yarn install --frozen-lockfile
RUN yarn# Expose port 8888 - note that docs port is 8080
EXPOSE 8888# Set the default command to run when starting the container
CMD  pm2-runtime app.js --name dex-transaction-ws

2、配置k8s pods yaml文件

---
apiVersion: apps/v1
kind: Deployment

查询pods运行情况

~# kubectl get pods -n biking |grep dex-transaction-ws
dex-transaction-ws-5498654dff-hrpw9                   1/1     Running   1 (37h ago)   3d13h
~# kubectl get deployment -n biking |grep dex-transaction-ws
dex-transaction-ws                   1/1     1            1           4d14h
~# kubectl get ingress -n biking |grep dex-transaction-ws
dex-transaction-ws        biking-ingress   dex-test.cuiwjrpcvi.com,dexws-test.cuiwjrpcvi.com                         172.16.10.202,172.16.10.203   80, 443   4d14h

3、编写jenkins的pipeline文件

// 参数构建
pipeline {agent anyparameters {gitParameter(name: 'BRANCH_TAG', type: 'PT_BRANCH_TAG', branchFilter: 'origin/(.*)', defaultValue: 'main', selectedValue: 'DEFAULT', sortMode: 'DESCENDING_SMART', description: '请选择需要部署的代码：')choice(name: 'mode', choices: ['deploy','rollback'], description: '请选择发布或者回滚？')        choice(name: 'ENVMENT', choices: ['sit','exp','gray','prod'], description: '环境参数')        string(name: 'iname', defaultValue: 'dex-transaction-ws', description: '服务名称')}environment {dest_path = "/var/jenkins_home/workspace/${JOB_NAME}"job_path = "/data/docker-compose/jenkins/jenkins_home/workspace/${JOB_NAME}"mod_path = "/data/docker-compose/jenkins/jenkins_home/mod"}stages {stage('clean'){steps {cleanWs(cleanWhenAborted: true, cleanWhenFailure: true, cleanWhenNotBuilt: true, cleanWhenSuccess: true, cleanWhenUnstable: true, cleanupMatrixParent: true, disableDeferredWipeout: true,deleteDirs: true)}    }        stage('从 gitlab 中拉取代码') {when {environment name: 'mode',value: 'deploy'}steps {deleteDir()checkout([$class: 'GitSCM', branches: [[name: "${params.BRANCH_TAG}"]],gitTool: 'Default', userRemoteConfigs: [[url: 'https://gitlab.abc.net/bk/spot/dex-transaction-ws.git', credentialsId: 'gitlab-deploy',]]])}}stage('Node Install And Build docker image'){steps{script{sh """docker build --build-arg SVC_NAME=${iname} -t harbor.abc.com/test/${iname}:$ENVMENT ."""}}}stage('Push image to hub'){steps{script{withCredentials([usernamePassword(credentialsId: 'harbor-secret-dev',, passwordVariable: 'password', usernameVariable: 'username')]) {sh 'docker login -u ${username} -p ${password}  harbor.abc.com'}sh 'docker push harbor.abc.com/test/${iname}:$ENVMENT'}}}stage('deploy Server'){steps{script{sh """curl -X PUT \-H "content-type: application/json" \-H "Cookie: KuboardUsername=admin; KuboardAccessKey=ccpyiaxei7i8.8kjh69sh8amx8sp45x6i3t2tzwscdgeb" \-d '{"kind":"deployments","namespace":"test","name":"${iname}","images":{"harbor.cuiwjrpcvi.com/bktest/${iname}":"harbor.cuiwjrpcvi.com/bktest/${iname}:${ENVMENT}"}}' \"http://X.X.X.X:1234/kuboard-api/cluster/Test/kind/CICDApi/admin/resource/restartWorkload"    curl -X PUT \-H "Content-Type: application/yaml" \-H "Cookie: KuboardUsername=admin; KuboardAccessKey=ccpyiaxei7i8.8kjh69sh8amx8sp45x6i3t2tzwscdgeb" \-d '{"kind":"deployments","namespace":"test","name":"${iname}"}' \"http://X.X.X.X:1234/kuboard-api/cluster/Test/kind/CICDApi/admin/resource/restartWorkload""""}}}}
}
