ECS，未生成cloudwatch日志

如何解决ECS，未生成cloudwatch日志

我的cloudwatch日志运行正常。

然后我对容器被杀死（ecs,automated task/image deletion working strangely）有疑问

因此，我尝试使用最新文档（https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/EC2NewInstanceCWL.html）更新ECS代理设置

您只需要添加以下几行

#!/bin/bash
curl https://s3.amazonaws.com/aws-cloudwatch/downloads/latest/awslogs-agent-setup.py -O
chmod +x ./awslogs-agent-setup.py
./awslogs-agent-setup.py -n -r us-east-1 -c s3://DOC-EXAMPLE-BUCKET1/my-config-file

在此之前，我有以下几行内容：（就cloudwatch日志而言，它实际上是有效的）

#!/bin/bash

# https://docs.aws.amazon.com/AmazonECS/latest/developerguide/using_cloudwatch_logs.html

# Install awslogs and the jq JSON parser
yum install -y awslogs jq

# Inject the CloudWatch Logs configuration file contents
cat > /etc/awslogs/awslogs.conf <<- EOF

log_stream_name = {cluster}/{container_instance_id}

[/var/log/messages]

log_group_name = /var/log/messages
log_stream_name = {cluster}/{container_instance_id}
datetime_format = %b %d %H:%M:%S

log_group_name = /var/log/ecs/ecs-init.log

log_group_name = /var/log/ecs/audit.log
log_stream_name = {cluster}/{container_instance_id}

以下是运行ecs初始化的python脚本。我无法理解它（它中断了）

wget https://s3.amazonaws.com/aws-cloudwatch/downloads/latest/awslogs-agent-setup.py

该文件太大，无法粘贴到此处。
