Configsets support

[lony]

When I use the following method http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-init.html#aws-resource-init-configsets

I get ValueError('config property is required') as a workaround I change one of my changesets to config, but is there better way to "validate" Metadata?

Can you give a snippet of the code that you're using that isn't working the way you expect?

print(template.to_json())

Results in:

Traceback (most recent call last):
  File "pp.py", line 65, in <module>
    group='root'),
  File "/Users/lony/Desktop/data-platform/src/operations/jenkins/venv/lib/python2.7/site-packages/troposphere/cloudformation.py", line 187, in __init__
    self.validate(data, dict(kwargs))
  File "/Users/lony/Desktop/data-platform/src/operations/jenkins/venv/lib/python2.7/site-packages/troposphere/cloudformation.py", line 207, in validate
    raise ValueError('config property is required')
ValueError: config property is required

Just because I don't name one configset "config". Even if it is valid by AWS.

This is months later but the solution is to write it as:

`Metadata=Metadata(

Usage

            # http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-init.html
            Init(
                    InitConfigSets(configSets=
                        {"ascending": ["config1", "config2"]}
                ),
                'config1': InitConfig(
                        files=InitFiles({

etc; `

It's mildly inconsistent with the general troposphere API....

I was having the same issue, I used this and it seems to work for me:

Metadata=Metadata(Init(
        InitConfigSets(InstallAndConfigure=['config']),
        config=InitConfig(
            commands={
                '01_setup_aws': {
                    'command': Join('', [
                        'aws configure set s3.signature_version s3v4\n',
                        'aws configure set region ', Ref("AWS::Region")
                    ])
                }
            }
        ),
    ))

A similar issue occurs when you try to use the TemplateGenerator to read an existing CFT that contains a AWS::CloudFormation::Init section with no "config" property, even though it has a "configSets" property. See https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-init.html
