无法使用 kaniko 从 GitLab CI 构建 Docker 映像并将其推送到（私有）Artifactory

我正在设计一个 GitLab CI 管道来为给定的服务构建一个 Docker 镜像。

这是迄今为止 Gitlab CI 清单（相关摘录）的样子：

...

publish-docker-image:
  stage: publish
  dependencies:
    - assemble
  image:
    name: docker.tld.com/namespace/kaniko:latest # At work they offer a custom kaniko image
    entrypoint: [""]
  script:
    - mkdir --parents /kaniko/.docker/
    - mv $kaniko_config /kaniko/.docker/config.json # $kaniko_config is a file variable from GitLab CI
    - /kaniko/executor --context $CI_PROJECT_DIR --dockerfile $CI_PROJECT_DIR/Dockerfile --destination artifactory.tld.com/artifactory/docker-snapshot/organization/project/kaniko-test:0.1.0

该$kaniko_config文件转换为以下 JSON：

{
  "auths": {
    "https://artifactory.tld.com/": {
      "username": "the_real_username",
      "password": "the_real_password"
    }
  }
}

现在，每次运行管道时，我都会得到以下输出：

$ mkdir --parents /kaniko/.docker/
$ mv $kaniko_config /kaniko/.docker/config.json
$ cat /kaniko/.docker/config.json
{
  "auths": {
    "https://artifactory.tld.com/": {
      "username": "the_real_username",
      "password": "the_real_password"
    }
  }
}
$ /kaniko/executor --context $CI_PROJECT_DIR --dockerfile $CI_PROJECT_DIR/Dockerfile --destination artifactory.tld.com/artifactory/docker-snapshot/organization/project/kaniko-test:0.1.0

Cleaning up file based variables

我在这里做错了什么？此外，我不知道为什么错误消息上有https://artifactory.tld.com/v2/(the /v2)，因为我没有使用类似的东西。
