What is your suggestion?

Allow users to specify a file on disk for coder create command, e.g. through a flag --parameter-file

Why do you want this feature?

1. Allows coder create to be more easily used in scripts. Today we prompt, which is hard to automate.
2. Bug: can't use Backspace in "Specify a name for your workspace" #1226 stems from a fix that was made to allow long inputs to be entered on macOS terminal. If we revert change to fix the backspace bug, we need some workaround method that will allow long inputs on the CLI for macOS, and this parameter file fits the bill.
3. General usability. Users that create more than one similar workspace today are forced to reenter the same data at prompts.

Are there any workarounds to get this functionality today?

Not as such, although they can enter parameters at the prompts.

Are you interested in submitting a PR for this?
