有什么用我也不想说了，这个是k8s CI/CD,进阶玩家玩的了，比你们喜欢Arg CD更科学，更现代

在 Kubernetes 中安装 KubeVela

helm repo add kubevela https://charts.kubevela.net/core
helm repo update
helm install --create-namespace -n vela-system kubevela kubevela/vela-core --wait

启动VelaUX 控制台

#启用控制台

wget https://github.com/kubevela/kubevela/releases/download/v1.9.6/kubectl-vela-v1.9.6-linux-amd64.zip
mv kubectl-vela /usr/bin/
vela addon enable velaux
#暴露端口
vela addon enable velaux serviceType=NodePort
vela status addon-velaux -n vela-system --endpoint

登录完控制台配置集群

创建一个你的应用

apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
  name: first-vela-app
spec:
  components:
    - name: express-server
      type: webservice
      properties:
        image: oamdev/hello-world
        ports:
         - port: 8000
           expose: true
      traits:
        - type: scaler
          properties:
            replicas: 1
  policies:
    - name: target-default
      type: topology
      properties:
        # local 集群即 Kubevela 所在的集群
        clusters: ["你的K8s集群名字"]
        namespace: "default"
    - name: target-prod
      type: topology
      properties:
        clusters: ["你的K8s集群名字"]
        # 此命名空间需要在应用部署前完成创建
        namespace: "prod"
    - name: deploy-ha
      type: override
      properties:
        components:
          - type: webservice
            traits:
              - type: scaler
                properties:
                  replicas: 2
  workflow:
    steps:
      - name: deploy2default
        type: deploy
        properties:
          policies: ["target-default"]
      - name: manual-approval
        type: suspend
      - name: deploy2prod
        type: deploy
        properties:
          policies: ["target-prod", "deploy-ha"]

创建你的应用

vela env init prod --namespace prod
# 执行
vela up -f first-app.yaml

vela status first-vela-app

最后集成你的喜欢的GitLab或者jnekins,(本人比较喜欢Jenkins技术含量比较丰富，gitlab-ci就不做例子了，太幼稚简单了)

下面一条是jenkinsfile CI/CD(配置了动态slave，docker in docker)

pipeline {
    agent {
        kubernetes {
            inheritFrom 'devops'

        }
    }

     stages {
      stage('Get Code') {
        steps {
     checkout scmGit(branches: [[name: '*/release']], extensions: [], userRemoteConfigs: [[credentialsId: 'll', url: 'http://git.XXXX.com/wallet-pay/api.git']])
         }
           }
      stage('Test-docker....') {
            steps {
            
            //建议使用docker阶级构建一个容器即可
                container('docker'){
                     sh 'docker BUILD'
                    //script{
                     //dockerlmage =  docker.build name + ":" + ${BUILD_ID}
            }
               }

   stage ('Deploy') {
    steps {
            sh '''
        curl -X POST -H 'content-type: application/json' --url http://192.168.0.193:30000/api/v1/webhook/9349hjwlasmpbo41 -d '
        {
          "upgrade": {
            "express-server": {
              //你的镜像
              "image": "${image}"
            }
          },
          "codeInfo": {
            "commit": "",
            "branch": "",

        }
        '
        '''
