I have a CloudFormation template that asks for these parameters

----- cftemplate.yaml -----




    Description: Subnet for the Instance

    Type: 'AWS::EC2::Subnet::Id'


    Description: Security Group for Instance

    Type: 'List<AWS::EC2::SecurityGroup::Id>'**




   Type: AWS::EC2::Instance



    **SubnetId: !Ref Subnet

    SecurityGroupIds: !Ref SecurityGroups**


----- cftemplate.yaml -----

Now for deploying stack, I'm using the below command:

aws cloudformation create-stack --stack-name StackName --template-body file://cftemplate.yaml --parameters file://params.json

And params.json have:

---- params.json ----- 












----- params.json -----

Now I want to eliminate the use of JSON, Can anyone help me with the shorthand syntax for the command that should provide the same effect as the above code?

The CLI would be:

aws cloudformation create-stack \

    --stack-name StackName \

    --template-body file://cftemplate.yaml \

    --parameters ParameterKey=Subnet,ParameterValue=subnet-11111111 ParameterKey=SecurityGroups,ParameterValue=sg-111111111\\,sg-222222222

Verify the command using your parameters:

aws cloudformation create-stack --stack-name StackName --template-body file://instance.yaml --parameters ParameterKey=Subnet,ParameterValue=subnet-0ae6ce0f9bbf52251 ParameterKey=SecurityGroups,ParameterValue=sg-06d2a3e9c8aa99620\\,sg-004d23d188ec1146f

and should result in deploying stack:


    "StackId": "arn:aws:cloudformation:us-east-1:xxxxxx:stack/StackName/61fbacd0-d3b0-11ea-970a-0ad23187ddb2"
