使用 Docker 將 Node/express 應用程序運行到 EC2 時出現 CloudWatch“UnknownEndpoint”錯誤

Question

我嘗試使用 docker 圖像和此命令在 ec2 上運行節點/快速應用程序“ sudo docker run -it -p 127.0.0.1:3000:3000 name/app:latest" ，我收到以下錯誤：

UnknownEndpoint: Inaccessible host: `logs.us-east-1.amazonaws.com’ at port `undefined’. This service may not be available in the `us-east-1' region.

AWS AMI ：ubuntu/images/hvm-ssd/ubuntu-jammy-22.04-amd64-server-20220912

"@aws-sdk/client-cloudwatch-logs": "^3.183.0", HTTPS 在服務器上啟用

如果我在 ec2 上克隆 repo 並使用“ pm2 --name appName start npm -- start ”運行它，它運行良好。

你能幫我理解如何解決這個問題嗎？

我通過使用帶有以下標志的 docker host.network 解決了這個問題docker -.network host ，如此處所述。
