如何使用 jenkins 部署有状态应用程序

Question

长话短说；博士有谁知道允许部署有状态应用程序的 Jenkins 插件

我正在使用 Jenkins 通过多分支 CI/CD 管道自动执行开发过程。我正在尝试部署有状态应用程序。我正在使用“Kubernetes Continuous Deploy Version1.0.0”插件进行部署管道按预期正确运行，除了一部分。

状态为绿色，但是，有状态集未在 k8s 集群上启动或更新。当我检查状态时，我的插件似乎跳过了我提供的 YAML。 “将应用程序部署到 Kubernetes”阶段的状态：

            Starting Kubernetes deployment
        Loading configuration: /var/lib/jenkins/workspace/algo-1_master/Preprod/Trader/statefulset_algo_1.yaml
        Skipped unsupported resource: StatefulSet(apiVersion=apps/v1, kind=StatefulSet,

    , template=PodTemplateSpec(metadata=ObjectMeta(annotations={},

        valueFrom=EnvVarSource(configMapKeyRef=null, fieldRef=null, resourceFieldRef=null,

         EnvVar(name=API_KEY, value=null, valueFrom=EnvVarSource(configMapKeyRef=null, fieldRef=null, resourceFieldRef=null,

        additionalProperties={}), additionalProperties={})], envFrom=[], image=arieltar/algo-1,

 additionalProperties={}), updateStrategy=null, volumeClaimTemplates=[], additionalProperties={}), status=null, additionalProperties={})
            Finished Kubernetes deployment

我的流水线如下

pipeline {
    environment {
      dockerimagename = "arieltar/algo-1"
      dockerImage = ""
    }

    agent any

    stages {

      stage('Checkout Source') {
        steps {
          git 'https://github.com/finance-dataspider/spiderdoc.git'
        }
      }

      stage('Build image') {
        steps{
          script {
            dockerImage = docker.build(dockerimagename,"./Preprod/Trader/")
          }
        }
      }

      stage('Pushing Image') {
        environment {
                registryCredential = 'dockerhub-reg'
            }
        steps{
          script {
            docker.withRegistry( 'https://registry.hub.docker.com', registryCredential ) {
              dockerImage.push("latest")
            }
          }
        }
      }

      stage('Deploying App to Kubernetes') {
        steps {
          script {
            kubernetesDeploy(configs: "Preprod/Trader/statefulset_algo_1.yaml", kubeconfigId: "kubernetes")
          }
        }
      }

    }

  }

简单的解决方案，如果插件不支持有状态集并且您想部署它，请不要使用它。

只需将 kubectl 安装到 bash 中并直接使用它来应用 YAML

stage('Deploy Image') {
      steps{
        script {
          docker.withRegistry( '', registryCredential ) {
            dockerImage.push("$BUILD_NUMBER")
             dockerImage.push('latest')

          }
        }
      }
    }
    stage('Deploy to K8s') {
      steps{
        script {
          sh "sed -i 's,TEST_IMAGE_NAME,harshmanvar/node-web-app:$BUILD_NUMBER,' deployment.yaml"
          sh "cat deployment.yaml"
          sh "kubectl --kubeconfig=/home/ec2-user/config get pods"
          sh "kubectl --kubeconfig=/home/ec2-user/config apply -f deployment.yaml"
        }
      }
    }
