AWS CodeDeploy 一直失败 - 找不到平台：没有清单

如何解决AWS CodeDeploy 一直失败 - 找不到平台：没有清单

我正在尝试排查问题，为什么我使用 AWS 代码管道的部署失败了。我正在使用 AWS 代码部署从 S3 进行部署。

我有一个带有 CentOS 8 服务器的 EC2 实例，架构为 x86_64，该应用程序是一个在 Nginx 上运行的网站

我的 appspec.yml 如下所示：

version: 0.1
os: linux
files:
  - source: /
    destination: /var/www/html/

从位于 /var/log/amazon/ssm/amazon-ssm-agent.log 中的日志中失败的原因

2021-03-06 17:11:22 错误 [logTraceDone @ trace.go.100] [ssm-document-worker] [18633a65-1007-4d73-b43b-54e7b06001d9] [DataBackend] [pluginName=aws:configurePackage] 确保包在本地可用 - 错误：找不到平台：找不到平台的清单：centos，版本 8，架构 x86_64

"runtimeStatus": {
    "configurePackage": {
      "status": "Failed","code": 1,"name": "aws:configurePackage","output": "\n----------ERROR-------\nFailed to find platform: no manifest found for platform: centos,version 8,architecture x86_64\nFailed to find platform: no manifest found for platform: centos,architecture x86_64\n","startDateTime": "2021-03-06T11:41:17.471Z","endDateTime": "2021-03-06T11:41:22.047Z","outputS3BucketName": "","outputS3KeyPrefix": "","stepName": "","standardOutput": "","standardError": "Failed to find platform: no manifest found for platform: centos,architecture x86_64\n"
    }

此外，如果我使用 cli 执行部署状态日志 aws deploy get-deployment-instance --deployment-id d-id --instance-id i-id

我得到的错误是

{
    "instanceSummary": {
        "deploymentId": "d-id","instanceId": "arn:aws:ec2:.............","status": "Failed","lastUpdatedAt": 1615032216.643,"lifecycleEvents": [
            {
                "lifecycleEventName": "ApplicationStop","startTime": 1615032216.503,"endTime": 1615032216.503,"status": "Failed"
            },{
                "lifecycleEventName": "DownloadBundle","status": "Skipped"
            },{
                "lifecycleEventName": "BeforeInstall",{
                "lifecycleEventName": "Install",{
                "lifecycleEventName": "AfterInstall",{
                "lifecycleEventName": "ApplicationStart",{
                "lifecycleEventName": "ValidateService","status": "Skipped"
            }
        ]
    }
}

是否知道此问题的根本原因是什么以及对此的解决方案是什么？
