CommaDelimitedList parameter and command line

[emmanuel...@menlosecurity.com]

How can I pass comma delimited list parameters at the command line?

HERE IS THE ERROR

aws --profile 7009 --output table --region us-west-1  cloudformation create-stack --stack-name Release001a --parameters ParameterKey=JumpHostCidrs,ParameterValue='52.53.216.135/32, 54.183.176.252/32' 

 --stack-policy-url http://s3.amazonaws.com/config.menlosecurity.com/cfn.d/Release/001a/deny_update_all.json --capabilities CAPABILITY_IAM --disable-rollback --template-url https://s3.amazonaws.com/config.menlosecurity.com/cfn.d/Release/001a/master.cfn

Parameter validation failed:

Invalid type for parameter Parameters[0].ParameterValue, value: [u'52.53.216.135/32', u'54.183.176.252/32'], type: <type 'list'>, valid types: <type 'basestring'>

make: *** [_cloudformation_s3_create_stack] Error 255

HERE IS THE RELEVANT SECTION OF THE TEMPLATE

    "JumpHostCidrs": {

      "ConstraintDescription": "must be a comma delimited list of 2 IP addresses x.x.x.x/32",

      "Default": "50.250.253.241/32, 50.250.253.241/32",

      "Description": "Comma-delimited list of 2 IP addresses",

      "Type": "CommaDelimitedList"

    },

Why is the awscli expecting the basestring type?

If I don't pass the parameter on the command line, the default value works fine and as expected in the template (Select(0... etc))

Any clue is appreciated.

It seems like what you're doing should be right, this seems to indicate that you should single quote AND escape the commas though: https://forums.aws.amazon.com/thread.jspa?threadID=142854

Not sure why, or if that will actually help.

It is actually an issue related to the awscli

https://github.com/aws/aws-cli/issues/1529

 I got it working by escaping the quotes or surrounding in single quotes:

ParameterKey=SecurityGroups,ParameterValue=\"sg-11111111,sg-22222222\"

'ParameterKey=SecurityGroups,ParameterValue="sg-11111111,sg-22222222"'
