AWS CodeDeploy无故失败

Question

我正在尝试使用AWS CodeDeploy将Java war文件部署到EC2实例。

我已经在这场战争的根源中添加了一个appspec.yml，内容如下：

version: 0.0
os: linux 
files:
  - source: /
    destination:  /var/scwcd/scwcd

我还创建了一个EC2实例，codeDeploy应用程序可以看到此Ec2实例。 我将此战争文件手动上传到我的S3存储桶，并将codeDeploy源设置为S3文件。 我还为CodeDeploy添加了足够的权限来访问S3和EC2实例。

但是部署始终会失败，并显示以下消息：

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

我检查了部署事件列表，发现每个动作都被跳过而没有错误代码：

我还检查了EC2实例，发现目标文件夹/ var / scwcd不存在。

有人知道我错过了吗？

谢谢！

您是否已在EC2实例上安装了CodeDeploy代理[1]？跳过所有事件通常意味着代理未调用CodeDeploy服务端点[2]。

您可以在实例首次启动时使用EC2 UserData中的以下命令来安装代理程序：

Amazon Linux / RHEL

    // Initialize the GraphServiceClient.
    GraphServiceClient client = await MicrosoftGraphClient.GetGraphServiceClient();

    var subRequest = client.Subscriptions.Request();
    var result = subRequest.GetAsync().Result;

    return Ok(result);
