aws
Cloudformation external parameter file do not support YAML file
I used aws-cli to update my stacks, and want to use an external yaml file (dev.yaml) as parameters file like below:
aws cloudformation update-stack --stack-name test --template-body file://./api-test.yaml --parameters file://./dev.yaml
In dev.yaml, it only has:
---
- ParameterKey: APICacheClusterSize
ParameterValue: '1.6'
However, I got this Error message when I run the update command above:
Error parsing parameter '--parameters': Expected: '=', received: '-' for input:
---
- ParameterKey: APICacheClusterSize
^
ParameterValue: '1.6'
If I use JSON file with same context as below, and use it instead of dev.yaml, it works fine:
[
{
"ParameterKey": "APICacheClusterSize",
"ParameterValue": "1.6"
}
]
So, can the external parameters file for aws cloudformation be YAML file? or will...?
Hi, we currently don't have any plans to support YAML as part of the command line arguments. I will mark this as a feature request as I can see how it might be useful for some people.
The contents of the the file you provide to --parameters is loaded and dumped straight in as an argument so you can only have the file contents be in one of two formats:
Shorthand syntax:
ParameterKey=string,ParameterValue=string,UsePreviousValue=boolean
or JSON syntax:
[
{
"ParameterKey": "string",
"ParameterValue": "string",
"UsePreviousValue": true|false
}
]
+1 allowing YAML formatted data for --template-body but not for --parameters is awkward
since you can provide a template in yaml, you should be able to provide the parameters in yaml too i think this feature is a must-have
