我的 Bitbucket 管道在 CodeDeploy 步骤（部署到 EC2 实例）上失败

Question

这里是 AWS 新手。

我正在开发我的第一个 Bitbucket 管道以部署到 AWS。它分为三个步骤：

1. 压缩项目文件
2. 上传到 AWS S3 存储桶
3. 使用 CodeDeploy 将应用程序文件部署到 EC2 实例

这是我最近的跑步：

事实上，我认为这是进步！我第一次运行这个时，我自己在 6 分半钟左右停止了它，因为它似乎挂在这条线上：

aws deploy wait deployment-successful --deployment-id d-V1OU4NNG8

这次它自己失败了，至少提供了一些诊断信息可供查看。

            }
        }
    }
}

这似乎是相关信息：

        "errorInformation": {
            "message": "The overall deployment failed because too many individual instances failed deployment, too few healthy instances are available for deployment, or some instances in your deployment group are experiencing problems.", 
            "code": "HEALTH_CONSTRAINTS"
        }

好的，“失败的单个实例太多”、“运行状况良好的实例太少”——我只部署到一个 EC2 实例，而该实例失败了。无论出现什么问题，它都不会很快失败，大约需要 5 分钟以上才会失败。我想无论出现什么问题，或者是否需要检查其他诊断，这些都将在 AWS 端找到。我是 AWS 的新手。如果您能为我提供一些指导，告诉我在 AWS 端寻找什么以查找其他诊断，或者在哪里查找可能的错误配置，这将非常有帮助。谢谢！

我想通了。我在部署文件夹结构的根部丢失了文件 appspec.yml。

我添加了这个appspec.yml（它是简单的，我正在一步一步进行）：

version: 0.0
os: linux
files:
  - source: /
    destination: /api
hooks:

成功！
