写在最前

因为有一些比较前沿的springboot项目采用的是gradle没有使用maven，故而本篇章介绍一下如何自定义podTemplate接入gradle到kubesphere

1. 构建流程

KubeSphere 官方的 builder-base 代码库可以在 https://github.com/kubesphere/devops-agent/tree/master/gradle 找到，里面包含了 DevOps 相关的构建工具与配置。如果你需要下载其他版本的 OpenJDK，可以参考 JDK 官方提供的 https://jdk.java.net/java-se-ri/17-MR1，该页面列出了各个版本的详细下载信息，方便你根据需求选择合适的版本进行使用。

1.1 openjdk11

FROM kubespheredev/builder-base:v3.1.0

# gradle6
ENV GRADLE_VERSION 6.9.1
ENV GRADLE_HOME /usr/local/gradle-${GRADLE_VERSION}
ENV PATH ${GRADLE_HOME}/bin:$PATH

# 下载并安装 Gradle
RUN curl -fSL https://services.gradle.org/distributions/gradle-${GRADLE_VERSION}-bin.zip -o gradle.zip && \
    echo "$(curl -sLf https://services.gradle.org/distributions/gradle-${GRADLE_VERSION}-bin.zip.sha256) gradle.zip" | sha256sum --check && \
    unzip -q gradle.zip -d /usr/local && \
    rm -f gradle.zip

# 通过 RUN 检查 Gradle 版本
RUN gradle --version

# 下载并安装 OpenJDK 11（使用指定的 URL）
RUN curl -fSL https://download.java.net/openjdk/jdk11.0.0.2/ri/openjdk-11.0.0.2_linux-x64.tar.gz -o /tmp/openjdk-11.tar.gz && \
    tar -xzf /tmp/openjdk-11.tar.gz -C /usr/local && \
    rm -f /tmp/openjdk-11.tar.gz

# 设置 JAVA_HOME 和 PATH
ENV JAVA_HOME /usr/local/jdk-11.0.0.2
ENV PATH $JAVA_HOME/bin:$PATH

# 通过 RUN 检查 Java 版本
RUN java -version

1.2 openjdk17

FROM kubespheredev/builder-base:v3.1.0

# gradle6
ENV GRADLE_VERSION 6.9.1
ENV GRADLE_HOME /usr/local/gradle-${GRADLE_VERSION}
ENV PATH ${GRADLE_HOME}/bin:$PATH

# 下载并安装 Gradle
RUN curl -fSL https://services.gradle.org/distributions/gradle-${GRADLE_VERSION}-bin.zip -o gradle.zip && \
    echo "$(curl -sLf https://services.gradle.org/distributions/gradle-${GRADLE_VERSION}-bin.zip.sha256) gradle.zip" | sha256sum --check && \
    unzip -q gradle.zip -d /usr/local && \
    rm -f gradle.zip

# 通过 RUN 检查 Gradle 版本
RUN gradle --version

# 下载并安装 OpenJDK 17（使用指定的 URL）
RUN curl -fSL https://download.java.net/openjdk/jdk17.0.0.1/ri/openjdk-17.0.0.1+2_linux-x64_bin.tar.gz -o /tmp/openjdk-17.tar.gz && \
    tar -xzf /tmp/openjdk-17.tar.gz -C /usr/local && \
    rm -f /tmp/openjdk-17.tar.gz

# 设置 JAVA_HOME 和 PATH
ENV JAVA_HOME /usr/local/jdk-17.0.0.1
ENV PATH $JAVA_HOME/bin:$PATH

# 通过 RUN 检查 Java 版本
RUN java -version

2. 连接测试

2.1 jenkins-casc-config

我就用gradle6.9.1-openjdk11来演示

          limits:
            ephemeral-storage: "10Gi"
      securityContext:
        fsGroup: 1000

2.2 jenkinsfile

我写了一个简单的gradle的springboot小demo项目，你可以fork到你的gitee仓库里面去，https://gitee.com/tanqidi/gradle

pipeline {
  agent {
    node {
      label 'gradle6.9.1-openjdk11'
    }

  }
  stages {
    stage('拉取项目') {
      agent none
      when {
        environment name: 'BUILD_ENV', value: 'UAT_CICD'
      }
      steps {
        container('gradle') {
          git(credentialsId: 'gitee-secret', branch: 'master', url: 'https://gitee.com/tanqidi/gradle.git', changelog: true, poll: false)
        }

      }
    }

    stage('项目编译') {
      agent none
      when {
        environment name: 'BUILD_ENV', value: 'UAT_CICD'
      }
      steps {

      }
    }

          withCredentials([usernamePassword(credentialsId : 'aliyun-harbor-secret' ,passwordVariable : 'name' ,usernameVariable : 'passwd' ,)]) {
            sh 'echo "$name" | docker login $REGISTRY -u "$passwd" --password-stdin'
            sh 'docker push $REGISTRY/$HARBOR_NAMESPACE/$MODULE_NAME:$MODULE_VERSION'
          }

        }

      }
    }

    stage('部署到UAT环境') {
      agent none
      steps {
        container('gradle') {
          withCredentials([kubeconfigFile(credentialsId: "$KUBECONFIG_CREDENTIAL_ID", variable: 'KUBECONFIG')]) {
            script {
              sh "echo \'${DEPLOY_YAML}\' > deploy.yaml"
              sh "cat deploy.yaml"
              sh "envsubst < deploy.yaml | kubectl apply -f -"
            }

          }

        }

      }
    }

2.3 构建测试

选择gradle6.9.1-openjdk11，运行结果完整正确

2.4 试验访问

流水线会自动生成deployment，service要手动变更为NodePort来试验访问

3. 镜像制品

registry.cn-hangzhou.aliyuncs.com/tanqidi/build-gradle:gradle6.9.1-openjdk11
registry.cn-hangzhou.aliyuncs.com/tanqidi/build-gradle:gradle6.9.1-openjdk17

4. 操作总结

总的来说还是比较快速的就配置上了gradle并且构建通过了，在jenkins-case-conig那个部分比较晦涩难懂，可以看看前面的构建章节是有详细截图和描述的。
