Support for --parameter-values in sam local 0.3.0

[amirkav]

I read issues #400 and #456 and it looks like --parameter-values or --parameter-overrides are no longer supported for sam local invoke command. The ability to pass on parameters to a SAM Template when running locally is critical to test the behavior of the lambda function when deployed remotely.

Will --parameter-values or --parameter-overrides be supported for 'sam local invoke' command in future releases?

+1 for this feature. It's really helpful in local testing.

Closing. Was released with 0.6.1

SAM CLI --parameter-overrides doesn't use the same format as AWS CLI

$ aws cloudformation deploy help

       --parameter-overrides  (list) A list of parameter structures that spec-
       ify input parameters for your stack  template.  If  you're  updating  a
       stack  and  you don't specify a parameter, the command uses the stack's
       existing value. For new stacks, you must specify parameters that  don't
       have  a  default  value.  Syntax: ParameterKey1=ParameterValue1 Parame-
       terKey2=ParameterValue2 ...

       Syntax:

          "string" "string" ...

$ sam local start-api --help

       --parameter-overrides      Optional. A string that contains
                                  CloudFormation parameter overrides encoded
                                  as key=value pairs. Use the same format as
                                  the AWS CLI, e.g. 'ParameterKey=KeyPairName,
                                  ParameterValue=MyKey ParameterKey=InstanceTy
                                  pe,ParameterValue=t1.micro'

Users gets the following error while using aws cloudformation deploy format:

Error: Invalid value for "--parameter-overrides": ParameterKey1=ParameterValue1 is not in valid format. It must look something like 'ParameterKey=KeyPairName,ParameterValue=MyKey ParameterKey=InstanceType,ParameterValue=t1.micro'

Using sam local start-api --parameter-overrides Environment=dev throws:

Error: Invalid value for "--parameter-overrides": Environment=dev is not in valid format. It must look something like 'ParameterKey=KeyPairName,ParameterValue=MyKey ParameterKey=InstanceType,ParameterValue=t1.micro'

[jfuss]

@guijob The way you are specifying them are incorrect.

sam local start-api --parameter-overrides ParameterKey=Environment,ParameterValue=dev

@jfuss How override multi parameters ?

[martijnvankempen]

@pmayet You can override multiple parameters by using quotes.

Example:
--parameter-overrides "ParameterKey=Key1,ParameterValue=value1 ParameterKey=Key2,ParameterValue=value2"
