HashiCorp has released a new collection of tutorials on its Learn platform, teaching developers how to create and use custom Terraform providers. The tutorials focus on the Terraform HashiCups provider, which interacts with a fictional coffee-shop application. As learners progress through the tutorials, they will gain hands-on experience creating a custom Terraform provider using the Terraform Plugin SDK v2, exploring topics such as authentication, data sources, and debugging. By the end of the collection, developers will be equipped to create their own custom Terraform providers, leveraging the latest features in Terraform 0.13 and the Terraform Plugin SDK v2.
