服务无法下达任务

问题描述

好的，我不知道该在哪里进行故障排除。我正在尝试加速一个具有在ECS中运行的基本应用程序的堆栈。我将在下面显示cloudformation。但是我不断得到：

Ok, I am lost with where to to even troubleshoot this. I am trying to spin up a stack that has a basic app running in ECS. I will show the cloudformation below. But I keep getting:

我启动并运行了2个EC2实例，但均未出现在ECS中集群实例。

I get 2 EC2 instances up and running but neither appear in the ECS cluster instances.

以下是我的一些理论：

• 是我的user_data对吗？我需要对这些值进行细分吗？


• 健康状况检查


• 我的应用程序是使用端口4567的sinatra应用程序。

此外，我基本上是从并进行了简化它。所以这是我当前的json，

Also, I basically started with this, http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/quickref-ecs.html and just streamlined it. So here is my current json, https://gist.github.com/kidbrax/388e2c2ae4d622b3ac4806526ec0e502

另一方面，如何简化此过程以消除所有自动缩放？只是想让它以某种形式或方式工作？

On a side note, how could I simplify this to take out all autoscaling? Just want to get it working in some form or fashion?

推荐答案

为使ECS实例加入集群，以下内容必须满足以下条件：

In order for the ECS instance to join the cluster, the following conditions must be met:

1. 必须正确配置代理以通过群集> /etc/ecs/ecs.config 文件。


2. 必须为ECS实例分配正确的IAM角色，以允许ECS代理访问ECS终端节点。


3. ECS实例必须通过igw或NAT连接到Internet才能与控制平面联系。


4. ECS上的ECS代理实例应该正在运行。

1. The agent must be configured correctly to connect to the correctcluster via the /etc/ecs/ecs.config file.
2. The ECS instance must be assigned the correct IAM role to allow the ECS agent to access the ECS endpoints.
3. The ECS instance must have a connection to the Internet to contact the control plane, either via igw or NAT.
4. The ECS agent on the ECS Instance should be running.

用于配置 /etc/ecs/ecs.config 文件。

UserData that should be used to configure /etc/ecs/ecs.config file.

#!/bin/bash
echo ECS_CLUSTER=ClusterName >> /etc/ecs/ecs.config

您可以在/中检查COntainer实例未向Cluster注册的原因var / log / ecs / ecs-agent.log *

You can check reason for COntainer Instance not registering with Cluster in /var/log/ecs/ecs-agent.log*
