使用cloud-init用户数据 [英] Using cloud-init user data

问题描述

我有一个简单的cloud-init用户数据，正在传递给ec2。我在ec2实例上通过右键单击该实例并在其中设置用户数据来设置此数据。

以下是我的云初始化用户数据

 ＃cloud-config 
 
 runcmd：
-[ls，-l，/] 
- [sh，-xc， echo $（date）'：hello world！'] 
-[sh，-c，echo ========= hello world'===== ====] 
-[touch，/home/ec2-user/hello.txt] 
 
 final_message：系统终于在10秒后启动 
  

我从这里，我添加了触摸命令

我的期望是查看/var/log/cloud-init.log上的数据。但我在那里看不到。另外我也看不到任何错误，也看不到创建的hello.txt文件。

是否缺少某些内容？

我正在运行amazon linux实例，而不是ubuntu实例

解决方案

这是您第三条命令中的语法错误：

 -[sh，-c，echo ========== hello world'===== ====] 
  

这是有效的用户数据：

 ＃cloud-config 
 
 runcmd：
-[ls，-l，/] 
-[ sh，-xc，'echo $（date）：hello world！'] 
-[sh，-c，'echo ========= hello world ====== ==='] 
-[touch，/home/ec2-user/hello.txt] 
 
 final_message：系统终于启动了 
 
输出：{全部：'| tee -a /var/log/cloud-init-output.log'} 
  

注意cloud-init执行日志仅在 /var/log/cloud-init.log 中。指定 output 指令后，您应该在 /var/log/cloud-init-output.log 中看到输出。 / p>

I have a simple cloud-init user data that I am passing in to ec2. I set this data on my ec2 instance by right clicking the instance and setting the user data in there.

Following is my cloud-init user data

#cloud-config

runcmd:
 - [ ls, -l, / ]
 - [ sh, -xc, "echo $(date) ': hello world!'" ]
 - [ sh, -c, echo "=========hello world'=========" ]
 - [ touch, /home/ec2-user/hello.txt ]

final_message: "The system is finally up, after 10 seconds"

I got this example from here and I added the touch command

My expectation was to see the data on the /var/log/cloud-init.log. But I don't see it there. Also I don't see any errors nor see the hello.txt file created

Is there something that I am missing?

I am running an amazon linux instance and not an ubuntu instance

解决方案

It's an syntax error in your 3rd command:

- [ sh, -c, echo "=========hello world'=========" ]

This is a working user-data:

#cloud-config

runcmd:
 - [ ls, -l, / ]
 - [ sh, -xc, 'echo $(date) ": hello world!"' ]
 - [ sh, -c, 'echo "=========hello world========="' ]
 - [ touch, /home/ec2-user/hello.txt ]

final_message: "The system is finally up"

output : { all : '| tee -a /var/log/cloud-init-output.log' }

Notice that it shows cloud-init execution log only in /var/log/cloud-init.log. you should see output in /var/log/cloud-init-output.log after specifying the output directive.
