从 aws cloudformation describe-stacks 获取输出 [英] Getting Outputs from aws cloudformation describe-stacks
本文介绍了从 aws cloudformation describe-stacks 获取输出的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我使用下面的来获取堆栈信息 我想通过 AWS Cli:
I am using the below to get the stack information I want via AWS Cli:
aws cloudformation --region ap-southeast-2 describe-stacks --stack-name mystack
返回结果正常:
{
"Stacks": [
{
"StackId": "arn:aws:mystackid",
"LastUpdatedTime": "2017-01-13T04:59:17.472Z",
"Tags": [],
"Outputs": [
{
"OutputKey": "Ec2Sg",
"OutputValue": "sg-97e13dff"
},
{
"OutputKey": "DbUrl",
"OutputValue": "myUrl"
}
],
"CreationTime": "2017-01-13T03:27:18.893Z",
"StackName": "mystack",
"NotificationARNs": [],
"StackStatus": "UPDATE_ROLLBACK_COMPLETE",
"DisableRollback": false
}
]
}
但我不知道如何只返回 OutputValue 的值,即 myUrl
But I do not know how to return only the value of OutputValue which is myUrl
因为我不需要其余的,只需要 myUrl.
As I do not need the rest, just myUrl.
是否可以通过 aws cloudformation describe-stacks 实现?
Is that possible via aws cloudformation describe-stacks?
编辑
我刚刚意识到我可以使用 --query:
I just realize I can use --query:
--query "Stacks[0].Outputs[1].OutputValue"
将得到我想要的,但我想使用 DbUrl 否则如果输出的数量发生变化,我的结果将出乎意料.
will get exactly what I want but I would like to use DbUrl else if the number of Outputs changes, my result will be unexpected.
推荐答案
我得到了答案,使用下面的:
I got the answer, use the below:
--query "Stacks[0].Outputs[?OutputKey=='DbUrl'].OutputValue" --output text
