Feedback from the customer:

Hi team, I've worked out the issue with Fluent Bit. It turns out the docs incorrectly state the "Name" parameter in the agent configuration as "grafana-loki", when it's supposed to be "loki". It also recommends using "Url" as a parameter, when in fact it's supposed to be "httpusername", "httppasswd" and "host".

here's the Terraform code for it:

    logConfiguration = {
      logDriver = "awsfirelens"

      options = {
        Name        = "loki"
        Labels      = "{env=\"${var.environment}\",job=\"${var.name}\"}"
        Remove_Keys = "$container_id,$ecs_task_arn"
        Label_Keys  = "$container_name,$ecs_task_definition,$source,$ecs_cluster"
        Line_Format = "key_value"
        Host        = "logs-prod-026.grafana.net"
        Http_User   = "695835"

      }

      secretOptions = [{
        name      = "Http_Passwd"
        valueFrom = data.aws_secretsmanager_secret.grafana_cloud_loki_http_password.id
      }]
    }

The other parameter names needed to be updated as well to include underscores, while the *_Keys parameters expect dollar signs at the start of each reference key, as seen above.

Finally, this config works for the latest images: grafana/fluent-bit-plugin-loki:latest
