我的 build.gradle.kts 配置为使用UTC时间戳标记图像:

configure<DockerExtension> {
    configure(this.getProperty("javaApplication"), closureOf<DockerJavaApplication> {
        baseImage = "openjdk:8-jre-alpine"
        tag = "${name}:${Instant.now().epochSecond}"
    })
}

当我跑的时候 dockerBuildImage 本地任务,我可以看到我的标记图像:

$docker image ls
REPOSITORY     TAG          IMAGE ID       CREATED       SIZE

“构建docker”步骤的输出如下所示:

标签丢在哪里了 ?

请注意,第二步中的一些图像ID( docker image ls

save 和 load Bitbucket Pipelines' artifacts

首先,我稍微更改了标记方案:

configure<DockerExtension> {
    configure(this.getProperty("javaApplication"), closureOf<DockerJavaApplication> {
        baseImage = "openjdk:8-jre-alpine"
        tag = "${name}:${System.getenv("DOCKER_TAG")}"
    })
}

因此,我依赖于一个环境变量,而不是UTC时间戳 DOCKER_TAG

然后,定义“构建docker”步骤如下:

- step: &build-docker
    name: Build Docker images
    image:
      name: openjdk:8
    services:
      - docker
    script:
      - export DOCKER_TAG=${BITBUCKET_BUILD_NUMBER}
      - ./gradlew dockerBuildImage
      - docker save
        --output images.tar
        forklift-1:${DOCKER_TAG}
        forklift-2:${DOCKER_TAG}
        forklift-3:${DOCKER_TAG}
        forklift-3:${DOCKER_TAG}
    artifacts:
      - images.tar
    caches:
      - gradle-wrapper
      - gradle

我可以使用构建编号作为标记,但是可以提供任何值。

- step: &publish-docker
    name: Publish Docker images
    image:
      name: docker
    services:
      - docker
    script:
      - docker load --input images.tar
      - docker image ls
      - docker push â¦

这是有效的,因为 docker save

生成标准输出流的tarred存储库。包含所有父层, 和所有标签+版本
