# What does this do?
This does parameter validation for dynamic parameters in `wsbuilder`. All input parameters are validated in `coder/coder` before being sent to terraform.
The heart of this PR is [`ResolveParameters`](b65001e89c/coderd/dynamicparameters/resolver.go (L30-L30)).
# What else changes?
`wsbuilder` now needs to load the terraform files into memory to succeed. This does add a larger memory requirement to workspace builds.
# Future work
- Sort autostart handling workspaces by template version id. So workspaces with the same template version only load the terraform files once from the db, and store them in the cache.
This PR extracts dynamic parameter rendering logic from
coderd/parameters.go into a new coderd/dynamicparameters package. Partly
for organization and maintainability, but primarily to be reused in
`wsbuilder` to be leveraged as validation.
