Jenkins 您可能无法访问本地主机

我试图通过jenkins管道脚本构建sonarqube，在构建过程中，我遇到了无法访问localhost 9000的错误

注意：我可以在y浏览器中访问我的localhost sonar 9000，并且在上面的jenkins输出中有一个构建点url，比如localhost:9000，也可以从jenkins日志访问，但是在这行的末尾有一行，比如无法访问主机127.0.0.1

vi /etc/hosts
127.0.0.1 sonarqube

由于您的Jenkins正在docker容器中运行构建，如注释中所述，解决方案是使用IP地址或本地DNS名称从构建脚本中访问sonarqube，因为localhost不会解析为docker容器中的主机。

我认为这与代理有关。 如果您正在代理后运行sonar生命周期，请在Maven.m2/settings.xml中注释代理指令块

Jenkins是否在docker容器中执行构建？是的，我正在管道脚本中使用pod容器模板。我是否要在此处更新我的脚本？嗨，Ale，请帮助我们，由于此问题，我们正在影响整个项目。从容器中，无法作为本地主机访问主机。请改用外部DNS名称（或ip）。另外，你读过这个q/a吗：嗨，Alex，谢谢你的快速回复，我在/etc/hosts文件中有更新IP地址，比如10.0.0.4 localhost

def label = "worker-${UUID.randomUUID().toString()}"

podTemplate(label: label, containers: [
        containerTemplate(name: 'nodejs', image: 'node:10-buster', ttyEnabled: true, command: 'cat'),
            containerTemplate(name: 'docker', image: 'docker:1.12.6', command: 'cat', ttyEnabled: true),
    containerTemplate(name: 'sonarqube', image: 'sonarsource/sonar-scanner-cli:latest', command: 'cat', ttyEnabled: true),
    containerTemplate(name: 'kubectl', image: 'lachlanevenson/k8s-kubectl:v1.8.3', command: 'cat', ttyEnabled: true)

],
volumes: [
   hostPathVolume(mountPath: '/var/run/docker.sock', hostPath: '/var/run/docker.sock'),
]) {
  node(label) {
    def myRepo = checkout scm
    def gitCommit = myRepo.GIT_COMMIT
    def gitBranch = myRepo.GIT_BRANCH
    def shortGitCommit = "${gitCommit[0..10]}"
    def previousGitCommit = sh(script: "git rev-parse ${gitCommit}~", returnStdout: true)



    stage('sonar-scanner') {
     container('sonarqube') {
       sh "/opt/sonar-scanner/bin/sonar-scanner -X -Dsonar.host.url=http://localhost:9000 -Dsonar.login=admin"
      }
  }


}
