无法在Loki中获取日志记录

Question

我根据这位医生创建了ECS集群

我使用的是CloudFormation模板：

    AWSTemplateFormatVersion: "2010-09-09"
    Resources:
      # ...
      TaskDefinition:
        Type: AWS::ECS::TaskDefinition
        Properties:
          Family: !Sub "${Application}-${Env}"
          ExecutionRoleArn:
            Fn::ImportValue:
              !Sub "${Env}-TaskExecutionRole"
          Cpu: 256
          Memory: 256
          ContainerDefinitions:
            - Name: nextjs
              Image: nextjs
              DependsOn:
                - containerName: log_router
                  condition: START
              Essential: true
              LogConfiguration:
                LogDriver: awsfirelens
                Options:
                  Name: loki
                  Url: "http://loki.xxx.com/loki/api/v1/push"
                  Labels: "{job=\"firelens\"}"
                  RemoveKeys: "container_id,ecs_task_arn"
                  LabelKeys: "container_name,ecs_task_definition,source,ecs_cluster"
                  LineFormat: key_value
              Links:
                - log_router
            - Name: nginx
              Image: nginx
              DependsOn:
                - containerName: nextjs
                  condition: START
              Essential: true
              PortMappings:
                - ContainerPort: 80
              LogConfiguration:
                LogDriver: awsfirelens
                Options:
                  Name: loki
                  Url: "http://loki.xxx.com/loki/api/v1/push"
                  Labels: "{job=\"firelens\"}"
                  RemoveKeys: "container_id,ecs_task_arn"
                  LabelKeys: "container_name,ecs_task_definition,source,ecs_cluster"
                  LineFormat: key_value
              Links:
                - nextjs
                - log_router
            - Name: log_router
              Image: grafana/fluent-bit-plugin-loki:latest
              Essential: true
              FirelensConfiguration:
                Type: fluentbit
                Options:
                  enable-ecs-log-metadata: true
              LogConfiguration:
                LogDriver: awslogs
                Options:
                  awslogs-group: firelens-container
                  awslogs-region: us-east-1
                  awslogs-create-group: true
                  awslogs-stream-prefix: firelens
              memoryReservation: 50

所有三个容器都已启动并正在运行，但我在CloudWatch中得到了以下错误消息：

无法加载输出插件“loki”

屏幕截图(对不起，但是当我把它作为图像添加时，它失败了)：https://imgur.com/qnE0Cjd

而Grafana Loki是空的

哪里出错了？它是否与DependsOn或Links有关？

因为同样的问题而挣扎。结果证明那些医生是错的。插件的名字是"grafana-loki"，而不是像文档中所说的"loki“。也许这改变了一些时间，而文档只是过时了。

"logConfiguration": {
    "logDriver": "awsfirelens",
    "options": {
        "Name": "grafana-loki",
        "Url": "https://[...]/loki/api/v1/push",
        "Labels": "{job=\"firelens\"}",
        "RemoveKeys": "container_id,ecs_task_arn",
        "LabelKeys": "container_name,ecs_task_definition,source,ecs_cluster",
        "LineFormat": "key_value"
    }
},
