AppRegistry — Service Catalog AppRegistry

AWS docs: https://docs.aws.amazon.com/servicecatalog/latest/dg/applications.html

Service Catalog AppRegistry groups related AWS resources into named applications. Overcast implements the REST-JSON path-based API under /applications — all operations return JSON and error with application/json envelopes.

A CloudFormation stack or any standalone resource can be associated with an application; the web UI shows a “belongs to application X” banner on resource detail pages when a match is found.

CloudFormation integration

Resource type	Status	Notes
`AWS::ServiceCatalogAppRegistry::Application`	✅ Supported	`GetAtt` attributes: `Id`, `Arn`, `Name`, `ApplicationName`, `ApplicationTagKey`, `ApplicationTagValue`.
`AWS::ServiceCatalogAppRegistry::ResourceAssociation`	✅ Supported	Physical ID is `<appId>/<resourceType>/<resource>`.

CDK awsApplication tag auto-association: the provisioner scans each resource’s Tags for an awsApplication=<app-arn> entry (propagated by CDK’s Application L2 construct) and records a direct association with the owning application immediately after provisioning. Resources tagged this way are returned from ListAssociatedResources without requiring the web UI to expand the parent stack.

Endpoints

Application lifecycle

Operation	Status	Notes	AWS Docs
`CreateApplication`	✅ Supported	Auto-populates `applicationTag.awsApplication = <arn>` to match real AppRegistry. ID is a generated short identifier; ARN uses the standard `arn:aws:servicecatalog:...` format.	docs
`GetApplication`	✅ Supported	Lookup accepts application name, ID, or ARN.	docs
`ListApplications`	✅ Supported	No pagination (`nextToken` never returned).	docs
`DeleteApplication`	✅ Supported	Also removes all resource associations for the application.	docs
`UpdateApplication`	✅ Supported	Updates `name` (with collision detection) and `description`; bumps `lastUpdateTime`.	docs

Resource associations

Operation	Status	Notes	AWS Docs
`AssociateResource`	✅ Supported	Only `resourceType=CFN_STACK` is exercised today, but any resource type/ARN pair is accepted. URL-encoded resource ARN in the path.	docs
`DisassociateResource`	✅ Supported		docs
`ListAssociatedResources`	✅ Supported	No pagination.	docs
`GetAssociatedResource`	✅ Supported		docs

Attribute groups

Operation	Status	Notes	AWS Docs
`CreateAttributeGroup`	✅ Supported	Inert tier — attributes JSON is stored verbatim.	docs
`GetAttributeGroup`	✅ Supported	Lookup accepts name, ID, or ARN.	docs
`ListAttributeGroups`	✅ Supported	No pagination.	docs
`UpdateAttributeGroup`	✅ Supported	Name, description, and attributes can all be patched.	docs
`DeleteAttributeGroup`	✅ Supported	Does not cascade to associations.	docs
`AssociateAttributeGroup`	✅ Supported	Attribute group is accepted by name, ID, or ARN.	docs
`DisassociateAttributeGroup`	✅ Supported		docs
`ListAssociatedAttributeGroups`	✅ Supported	Returns the associated attribute group IDs for an application. No pagination.	docs

Tagging

Operation	Status	Notes	AWS Docs
`TagResource`	✅ Supported	Inert tier — merges into the shared ARN-keyed tag store.	docs
`UntagResource`	✅ Supported	`tagKeys` removed from the stored map.	docs
`ListTagsForResource`	✅ Supported	Returns the stored map, or `{}` for an ARN with no recorded tags.	docs

CloudFormation resources

Operation	Status	Notes	AWS Docs
`AWS::ServiceCatalogAppRegistry::Application`	✅ Supported	`GetAtt` attributes: `Id`, `Arn`, `Name`, `ApplicationName`, `ApplicationTagKey`, `ApplicationTagValue`.	docs
`AWS::ServiceCatalogAppRegistry::ResourceAssociation`	✅ Supported	Physical ID is `<appId>/<resourceType>/<resource>`.	docs
