从Gitlab流水线构建Packer

Question

我正在尝试在Gitlab流水线中执行我的packer构建，但在互联网上没有找到相关示例，不过我看到有一个Docker镜像，因此我希望这个YAML文件可以完成任务：

image: hashicorp/packer

stages:
  - build

build:
  stage: build
  script:
    - echo "Hello world"
    - packer build ./definition.json
  only:
    - master

但我不理解这种行为，CI拉取镜像、克隆存储库，最终结果却是这样：

Skipping Git submodules setup
Usage: packer [--version] [--help] <command> [<args>]

Available commands are:
    build       build image(s) from template
    console     creates a console for testing variable interpolation
    fix         fixes templates from old versions of packer
    inspect     see components of a template
    validate    check that a template is valid
    version     Prints the Packer version

Usage: packer [--version] [--help] <command> [<args>]

Available commands are:
    build       build image(s) from template
    console     creates a console for testing variable interpolation
    fix         fixes templates from old versions of packer
    inspect     see components of a template
    validate    check that a template is valid
    version     Prints the Packer version

ERROR: Job failed: exit code 127

它甚至没有打印我的 echo Hello World，并且打印了2次如何与CLI交互，为什么会出现这种情况？

我找到了如何修复它，我必须更改：

image: hashicorp/packer

转化为：

image:
  name: hashicorp/packer
  entrypoint:
    - '/usr/bin/env'
    - 'PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'
