詹金斯 kubernetes 插件存档/junit

Question

我有一个通过 kubernetes-jenkins 插件在 k8s 上运行的多容器作业。一切正常，但我无法junit 或archiveArtifacts 任何东西。我怀疑这是因为它只存在于容器中但不确定。代码如下：

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

podTemplate(
        label: label,
        containers: [
                containerTemplate(name: 'c1', image: 'c1'),
                containerTemplate(name: 'c2', image: 'c2'),
                containerTemplate(name: 'c3', image: 'c3'),
        ],
        volumes: [
                hostPathVolume(mountPath: '/var/run/docker.sock', hostPath: '/var/run/docker.sock'),
        ],
) {
    node(label) {
        stage('test') {
            container('c1') {
                sh """
                  cd /some-path
                  ./generate-junit-xml
                """

                archiveArtifacts allowEmptyArchive: true, artifacts: '/some-path/foo.xml'

                sh "cat /some-path/foo.xml"
            }
        }
    }
}

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

podTemplate(
        label: label,
        namespace: 'jenkins',
        imagePullSecrets: [ 'myreg' ],
        containers: [
                containerTemplate(name: 'c1', image: 'c1'),
                containerTemplate(name: 'c2', image: 'c2'),
                containerTemplate(name: 'c3', image: 'c3'),
        ],
        volumes: [
                hostPathVolume(mountPath: '/var/run/docker.sock', hostPath: '/var/run/docker.sock'),
        ],
) {
    node(label) {
        stage('test') {
            container('c1') {
                sh """
                  ./something-that-generates-junit-foo-xml
                """

                archiveArtifacts allowEmptyArchive: true, artifacts: '/abs/path/to/foo.xml'

                sh "cat /abs/path/to/foo.xml"
            }
        }
    }
}

构建日志显示以下输出：

[Pipeline] archiveArtifacts
Archiving artifacts
WARN: No artifacts found that match the file pattern "/some-path/foo.xml". Configuration error?
[Pipeline] sh
[test-pipeline] Running shell script
+ cat /some-path/unittest.xml
<?xml version="1.0" encoding="utf-8"?>...</xml>

非常感谢您的帮助！

Answer 1

junit 和 archiveArtifacts 都只能归档 WORKSPACE 内的文件，容器不会使用主机（jenkins WORKSPACE 所在的位置）刮除任何卷，除非您明确这样做

我解决了这个问题：
- 在我保存文件的地方添加额外的卷

hostPathVolume(hostPath: '/tmp', mountPath: '/tmp')

- 使用File Operations Plugin 将文件从tmp 复制到WORKSPACE

dir("/tmp/screenshots") {
    fileOperations([fileCopyOperation(excludes: '', flattenFiles: true, includes: '*.png', targetLocation: "${WORKSPACE}/screenshots")])
}

- 归档工件

archiveArtifacts allowEmptyArchive: true, artifacts: 'screenshots/**/*.png'

Answer 2

将工件复制到 Jenkins 工作区将解决它

age('test') {
        container('c1') {
            sh """
              ./something-that-generates-junit-foo-xml
            """
            sh 'cp /abs/path/to/foo.xml ${WORKSPACE}/abs/foo.xml'
            archiveArtifacts allowEmptyArchive: true, artifacts: 'abs/foo.xml'

            sh "cat /abs/path/to/foo.xml"
        }

如果你需要所有目录内容，你可以复制目录

sh 'cp -r /abs/path/to/ ${WORKSPACE}/abs/to'
archiveArtifacts allowEmptyArchive: true, artifacts: 'abs/to/*.xml'
