Cloudformation external parameter file do not support YAML file

Yaowenjie commented 7 years ago

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
