python - 分子在运行基本测试时抱怨“[703] 应该更改默认元数据：描述”

Question

我无法运行该 molecule test命令，因为它会引发以下错误，而我可以运行单个命令而不会出现任何错误（还提供了 --debug o/p 下面）

[701] Role info should contain platforms
/root/.config/pip/molecule-testing/meta/main.yml:1
{'meta/main.yml': {'__file__': u'/root/.config/pip/molecule-testing/meta/main.yml', u'dependencies': [], u'galaxy_info': {u'description': u'your description', u'license': u'license (GPLv2, CC-BY, etc)', u'author': u'your name', u'company': u'your company (optional)', u'galaxy_tags': [], '__line__': 2, '__file__': u'/root/.config/pip/molecule-testing/meta/main.yml', u'min_ansible_version': 1.2}, '__line__': 1}}

[703] Should change default metadata: company

但是，如果我在命令下运行，它会完美运行。那么，谁能指出为什么整个测试都失败了，我该怎么办？

TLDR；

ansible-lint这些是您应该修复的错误/良好做法。您可以lint通过简单地启动来自行运行舞台molecule lint。

从您当前的输出中，您只需要meta/main.yml在您的角色中添加一些信息。

到底发生了什么

每个molecule命令（例如converge, create, destroy, test...）都会针对您的角色启动一系列步骤（序列）。您可以在命令输出中看到步骤列表，如下面的示例所示，该示例取自您运行时的问题converge：

└── default
    ├── dependency
    ├── create
    ├── prepare
    └── converge

这些序列是默认配置的，但可以molecule.yml在您的场景目录中自定义。如果您对该主题感兴趣，可以查看我维护的开源角色的自定义。

默认情况下，converge序列不包含lint阶段。因此，您无需验证所有内容即可运行您的测试手册。

另一方面，该test序列包括以下所有步骤：

└── default
    ├── lint
    ├── dependency
    ├── cleanup
    ├── destroy
    ├── syntax
    ├── create
    ├── prepare
    ├── converge
    ├── idempotence
    ├── side_effect
    ├── verify
    ├── cleanup
    └── destroy

如您所见，第一个是lint，它（默认情况下）应该yamllint在您的所有 yml 文件上运行，然后是ansible-lint您的角色和测试手册，最后flake8是您的 python 文件（testinfra测试、自定义模块、自定义插件过滤器......） .

您的完整测试失败，因为最佳实践检查器ansible-lint正在报告您应该修复的问题。据我所知，它们非常微不足道，应该在你的几行中消失meta/main.yml
