Provider Scaffolding (skaff)

skaff is a Terraform AWS Provider scaffolding command line tool. It generates resource, data source, or function source files, along with test files which adhere to the latest best practices. These files are heavily commented with instructions, serving as the best way to get started with provider development.

Overview workflow steps

1. Figure out what you're trying to do:
   • Resource, data source, or function?
   • Name it.

   Tip

   Net-new resources should be implemented with Terraform Plugin Framework (i.e. the default skaff settings). See Terraform Plugin Development Packages and this issue for additional information.

2. Use skaff to generate provider code.
3. Go through the generated code, customizing as necessary.
4. Run, test, refine.
5. Remove "TIP" comments.
6. Submit a pull request.

Running skaff

1. Clone the Terraform AWS Provider repository.

2. Install skaff.

   make skaff
   

3. Change into the appropriate directory.

   • For resources and data sources, this is the service directory where the new entity will reside, e.g. internal/service/mq.
   • For functions, this is internal/functions.
4. Generate the resource, data source or function. For example,
   • skaff resource --name BrokerReboot.
   • skaff datasource --name IAMRole.
   • skaff function --name ARNParse.

To get help, enter skaff without arguments.
