Create a stack in HCP Terraform using `terraform stacks create ...` 2. Upload the configuration from a directory with the necessary files after initializing the stack. You can use https://github.com/quixoticmonk/hashiconf-stack as a sample stack. ### Additional Context _No response_ ### References _No response_ ### Generative AI / LLM assisted development? _No response_
