1. 确保ECS容器的日志驱动程序配置正确。

示例：

{
    "AWSEBDockerrunVersion": "1",
    "Logging": {
        "LogDriver": "awslogs",
        "Options": {
            "awslogs-group": "/aws/ecs/my-app",
            "awslogs-region": "us-east-1",
            "awslogs-stream-prefix": "my-app"
        }
    },
    "Image": {
        "Name": "my-app-image",
        "Update": "true"
    },
    "Ports": [
        {
            "ContainerPort": "80"
        }
    ]
}

2. 检查IAM角色的权限是否正确配置，以确保AWS CloudWatch日志代理可以访问要上传的日志组。

示例：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "logs:CreateLogGroup",
                "logs:CreateLogStream",
                "logs:PutLogEvents"
            ],
            "Effect": "Allow",
            "Resource": [
                "arn:aws:logs:us-east-1:123456789012:log-group:/aws/ecs/my-app:*"
            ]
        },
        {
            "Action": [
                "logs:DescribeLogGroups",
                "logs:DescribeLogStreams"
            ],
            "Effect": "Allow",
            "Resource": [
                "arn:aws:logs:us-east-1:123456789012:*"
            ]
        }
    ]
}

3. 确认AWS CloudWatch代理已正确配置在ECS集群中。

示例：

{
  "containerDefinitions": [
    {
      "name": "my-app",
      "image": "my-app-image",
      "essential": true,
      "portMappings": [
        {
          "containerPort": 80,
          "hostPort": 80
        }
      ],
      "logConfiguration": {
        "logDriver": "awslogs",
        "options": {
          "awslogs-group": "/aws/ecs/my-app",
          "awslogs-region": "us-east-1",
